Demolition for Townhouse Developments: A Guide for Small Developers

If you’re a small developer in Melbourne running your first — or your fifth — townhouse project, the demolition phase is the bit where the project either gets out of the gate cleanly or starts haemorrhaging time and money before a single footing is dug.

We see it both ways every week. A well-scoped demolition delivers a clean, build-ready site three weeks ahead of program, with every council, WorkSafe and EPA document filed away in the project folder. A poorly scoped one stalls a planning permit-approved 4-unit development for two months because the asbestos in the existing 1968 brick veneer wasn’t surveyed before the builder’s site supervisor arrived, the asset protection bond turned out to be three times what was budgeted, and the back-fence neighbour lodged a complaint that triggered a council inspection.

The difference between the two scenarios isn’t luck. It isn’t the suburb. And it isn’t even the size of the existing dwelling. It’s whether the demolition phase was scoped as its own project, with its own permits, its own engineering, its own asbestos pathway and its own EPA waste compliance — or whether it was bolted onto the builder’s contract as a $12,000 “demolition allowance” line item and waved through.

This guide is the plain-English version of what demolition actually involves on a small townhouse development in Melbourne in 2026 — what you’ll pay, how long it takes, where the regulatory traps sit, and how to make sure your demolition contractor is set up to hand over a build-ready site, not just a flattened block.

We’re a fully licensed Melbourne demolition company with Class B (non-friable) asbestos removal capability held in-house, and we run the demolition phase on small townhouse developments across every metropolitan Melbourne council and regional Victoria. Below is the framework we walk every developer-client through at the quote stage.

Quick answer: Demolition for a small townhouse development in Melbourne (typically 2–4 units on a single existing residential lot) is essentially a multi-asset residential demolition run with developer-grade compliance documentation. You’re usually demolishing one existing dwelling plus outbuildings, garages, fences, paths, driveways, and sometimes a granny flat. In 2026, expect to pay $22,000–$55,000+ for a typical dual-occupancy or 3–4 unit site demolition (depending on size, asbestos, access, slab depth and council), allow 8–14 weeks end-to-end from contract signing to handover (longer in Heritage Overlay areas), and budget for: a Section 29A demolition consent, an asset protection permit and bond, four service disconnections, a hazardous materials survey, licensed asbestos removal (almost certain on any pre-2003 dwelling), full EPA Waste Tracker compliance, and an asbestos clearance certificate. The single biggest source of variation on developer projects is whether the demolition contractor coordinates everything as one workstream — or hands you back a half-finished job that your builder then has to fix at variation rates.

Why Demolition for Townhouse Developments Is Its Own Discipline

Most demolition guides — including a few of our own — are written for homeowners doing a single knock-down rebuild. The framework is the same, but the risk profile is different when you’re a developer.

Three things change the moment a demolition becomes part of a development:

Holding cost is real money. Every week the site sits idle between contract signing and slab pour is a week of interest, council rates, insurance, and (often) bridging finance interest. A two-week demolition delay on a typical Melbourne 3-unit townhouse development can easily cost $4,000–$8,000 in holding alone — more than the difference between the cheapest and the most expensive compliant quote.
The site has to be build-ready, not just demolished. Your builder will not start excavating new footings while old strip footings are still in the ground. Your structural engineer won’t issue final slab design until the cleared block has a geotechnical report. Your Registered Building Surveyor won’t sign off on construction commencement without the asbestos clearance certificate. “Demolished” and “build-ready” are two different states, and they’re separated by several days of work that cheap demolition quotes routinely leave out.
The documentation is part of the project asset. When the units go to market in 12–18 months, the conveyancing checks on every sale will look for the demolition documentation — Section 29A consent, asbestos clearance certificate, EPA Waste Tracker records, asset protection final inspection. Missing documentation doesn’t just delay completion; it shows up at every future settlement and chips at end-sale value.

A demolition contractor who quotes the work as “just knocking the house over” is solving the cheapest 30% of the problem. The remaining 70% — coordination, documentation, build-ready handover, EPA compliance — is what separates a developer project that runs to program from one that doesn’t.

What’s Actually Being Demolished on a Typical Townhouse Site

The phrase “townhouse demolition” makes it sound like there’s a townhouse on site getting knocked down. On a small developer project, that’s almost never what’s happening. What you’re actually demolishing is the existing single dwelling and everything attached to its history — and the unit count refers to what you’re building, not what’s coming down.

A typical 2–4 unit townhouse development site in metropolitan Melbourne contains:

The existing dwelling — usually a single-storey weatherboard, brick veneer or double brick home from the 1940s–1990s; occasionally an inter-war or Edwardian on inner-east and middle-ring sites
A detached garage or carport — almost always with asbestos cement walls and/or Super Six roofing if pre-1990
One or more garden sheds, workshops or sleep-outs — often unauthorised additions with their own asbestos content
A driveway and crossover — concrete, brick paving or asphalt
Fencing on three or four boundaries — often fibro asbestos sheeting on side and rear boundaries in pre-1990 properties
Original strip footings, pier holes and slab edges below the visible structure
Sometimes a swimming pool — adds significant excavation, plumbing decommissioning and waste volume
Often buried fence post concrete, old septic systems, soak pits, fuel tanks and other artefacts that nobody’s seen for forty years until the excavator finds them

Every one of those needs to come out before the new build can start. The “house” might be 130 m² of floor area, but the total demolition footprint on a small townhouse development is routinely 200–280 m² of structure across multiple assets, plus 150–250 m² of hard surfaces (driveway, paths, slabs) and 60–120 linear metres of fencing.

That’s why a quote that says “demolish existing dwelling: $14,000” without itemising the rest is essentially fiction. The dwelling is half the work.

The Five-Stage Demolition Pathway for a Townhouse Development

Demolition on a small developer project follows the same statutory pathway as a single-house knock-down rebuild, but with more parallel workstreams and tighter coordination. Here’s the framework in the order it actually plays out.

Stage 1: Pre-Contract Due Diligence (Often Done by the Developer, Not the Demolisher)

Before you sign a demolition contract — ideally before you settle on the site — five checks should already be done:

VicPlan property report — zoning, overlays, heritage controls, vegetation protection, flood overlay, bushfire prone area status. Free, online, fifteen minutes.
Current Certificate of Title (within 3 months) — restrictive covenants, Section 173 agreements, easements. These can torpedo a multi-unit development independently of council approval.
Heritage Overlay schedule check — not just whether an overlay applies, but whether the property is individually significant, contributory, or non-contributory in the schedule. The three categories are treated very differently. We covered the council-by-council picture in our Council Demolition Permits in Melbourne: A Suburb-by-Suburb Overview.
Planning permit feasibility — a town planner’s pre-application advice or a planning permit application already in train before demolition is contracted. Demolishing in front of a refused planning permit is one of the most expensive avoidable mistakes a small developer can make.
Site walk with a licensed demolition contractor — most of the cost variables on a townhouse site (access, asbestos quantity, slab depth, tree retention, neighbour proximity, service location) are only visible on the ground. A serious quote needs a serious site inspection. Quotes generated from satellite photos under-measure systematically — almost always in the developer’s disfavour.

For the broader permit framework, see our Building Permits vs Demolition Permits in Melbourne and Victoria guide.

Stage 2: Statutory Approvals (Where Most of the Timeline Lives)

Once the planning permit for the new development is granted (or running in parallel, in the case of code-assessable projects), the demolition-side approvals stack runs as follows:

Section 29A demolition consent under the Building Act 1993 and Building Regulations 2018, granted by council. Required where the demolition meets the 50% volume test or affects any street-facing facade. On almost every townhouse development site, both tests are easily met. Statutory fee: 5.75 fee units = $96.66 for 2025–26.
Asset protection permit and bond from your local council. Fees range from around $323 in Wyndham to $465+ in Hume, with inner-east councils (Boroondara, City of Melbourne, Yarra, Stonnington, Port Phillip) charging a permit fee plus a separately calculated security bond — often $2,000–$10,000+ for a townhouse development site with multiple street frontage, kerb risk and street trees.
Hazardous materials survey by an independent licensed assessor. Typical cost $450–$1,200 depending on the size and complexity of the existing building and outbuildings.
WorkSafe Victoria asbestos removal notification — lodged by the licensed removalist a minimum of 5 days before non-friable removal commences.
Service disconnections lodged in parallel with all four utilities: electricity (and any solar PV system), gas, water and telecoms (NBN, copper or HFC). Lead times typically run 2–6 weeks. We unpack the detail in How We Disconnect Utilities Before Demolition in Melbourne.
EPA Waste Tracker registrations for every reportable priority waste stream — asbestos waste, contaminated soil if present, refrigerant gases from any air-conditioning still in place.
Building permit for demolition issued by the Registered Building Surveyor (RBS) once every upstream approval is in place.

⚠️ Common trap for small developers: Lodging these approvals sequentially instead of in parallel. Section 29A, asset protection, the four service disconnections and the asbestos survey should all be lodged within the same 48–72 hours of contracting the demolisher. Each one runs on its own clock; running them in series adds 4–6 weeks of pure waiting to a project that didn’t need it. A demolition contractor who can act as your authorised agent across the lot is worth the engagement.

Stage 3: Asbestos Removal and Site Strip

If the existing dwelling on your townhouse site was built or significantly renovated before 31 December 2003 — and most Melbourne townhouse development sites involve pre-2003 housing — assume asbestos is present until the hazardous materials survey says otherwise. For properties built between 1950 and 1989, the question isn’t whether there’s asbestos. It’s where, how much, and what licence class is needed.

Most townhouse-site asbestos is non-friable (bonded) — cement sheet eaves, cladding, garage walls, Super Six roofing, vinyl floor tiles, bathroom linings, fibro fences, switchboard backing boards. All of this is Class B work under the OHS Regulations 2017, and it’s the licence class we hold in-house.

The asbestos pathway on a typical townhouse site looks like this:

Hazardous materials survey by an independent licensed assessor (5–10 days including NATA-accredited lab turnaround)
Written report identifying every ACM location across the dwelling, garage, sheds, fences, electrical and wet-area linings
WorkSafe asbestos removal notification lodged a minimum of 5 days ahead
Class B licensed asbestos removal under wet methods, whole-sheet removal, double-bagging in 200 µm polythene
Independent licensed asbestos assessor issues the clearance certificate — this must not be the same party that did the removal
EPA Waste Tracker registration for every load, transport by an A10a or A10b permission holder, disposal at an EPA-authorised landfill
Soft-strip of any salvageable materials (hardwood floorboards, leadlight, fireplaces) before mechanical demolition begins

For townhouse sites carrying significant non-friable ACM, allow $4,000–$14,000 for the asbestos removal line, separately itemised from the structural demolition. For decade-by-decade guidance on what’s likely hiding in the dwelling, see our Asbestos in 1950s–1980s Melbourne Homes: What’s Likely Hiding guide. For licence verification, Licensed Asbestos Removal Victoria: How to Verify Your Contractor.

⚠️ Common trap for small developers: Quotes that bundle asbestos into “site prep” without itemising the licence class, the WorkSafe notification, the named independent assessor, the disposal facility, or the per-square-metre rate. Those quotes are pricing a non-compliant job. The asbestos line items on our full pricing framework are in The Cost of Asbestos Removal in Melbourne and Why It Varies.

Stage 4: Structural Demolition and Site Clearance

With approvals in place, asbestos removed, services disconnected and the perimeter secured with temporary fencing, the structural demolition itself takes:

2–4 days for a single-storey weatherboard or brick veneer with detached garage
3–5 days for a single-storey double brick home with outbuildings
5–7 days for a two-storey home with outbuildings
5–10 days for a larger or multi-asset site (e.g. two dwellings on a battle-axe lot)

A typical 5–13 tonne excavator with a grapple, pulveriser or hydraulic hammer attachment is the universal tool. Wrecking balls haven’t been used on residential demolitions in Melbourne for decades; implosion is reserved for high-rise. The detail of how the machinery decision actually gets made is in our Excavator vs Wrecking Ball vs Implosion: Modern Demolition in Melbourne guide.

Material is segregated on the ground as it comes out:

Clean concrete and brick stockpiled for crushing into recycled aggregate — the largest stream by weight on most townhouse sites
Steel and metal — roofing, plumbing, structural members, rebar from the slab — to scrap recovery
Clean timber — viable hardwood floorboards, structural members — to salvage or biomass
Mixed waste — drywall, insulation, fixtures, plastics — to a licensed mixed waste facility
Asbestos waste (already removed earlier, separately tracked) — to an authorised landfill

The metropolitan waste levy is $167.90 per tonne from 1 July 2025 — up roughly 28% from the prior year, with another rise scheduled. A typical townhouse site demolition generates 80–180 tonnes of mixed waste, so the levy alone runs into thousands of dollars. Aggressive on-ground segregation and on-site or local crushing is what keeps that number manageable. For the full EPA framework, see our EPA Victoria’s Rules for Construction and Demolition Waste in 2026.

Stage 5: Site Preparation for the New Build

This is the stage that separates a properly scoped townhouse demolition from a quick-and-dirty one — and it’s where most developer-side variation invoices end up coming from.

A build-ready townhouse development site at handover should have:

All slab and footings removed to clear depth — typically 600–900 mm on older Melbourne homes, deeper on pier-and-beam construction
All buried fence post concrete, garden walls, paving slabs and historic infrastructure dug out (not buried under graded fill)
All demolition rubble removed from site to lawful EPA-authorised facilities, with weighbridge dockets on file for every load
Asbestos clearance certificate issued by an independent licensed assessor where ACM was present
Top ~100 mm of soil in any zone where non-friable ACM was disturbed, removed and disposed of as asbestos-contaminated soil
Site graded to a level agreed with your builder in writing — referenced to the proposed finished floor level (FFL) of the new units, not to “level” as a vague target
Re-pegging by a registered surveyor to re-establish boundary references (original pegs are almost always destroyed during demolition)
Geotechnical investigation scheduled on the cleared block (geotech done before demolition tells you about the wrong soil)
Asset protection final inspection passed and bond released
Documentation pack handed across in physical and digital form — every permit, every notification, every certificate, every docket, every invoice

A clearer walkthrough of what each of those steps actually involves is in our Site Preparation After Demolition: What Happens Before Your New Build Starts guide.

⚠️ Common trap for small developers: Accepting handover before the asbestos clearance certificate is in your hand. Without it, your builder won’t start, your RBS won’t release construction commencement, and the soil under your future units may still be carrying disturbed ACM fibres. Settle for nothing less than a full documentation pack at the moment you take the site back from the demolisher.

What Demolition Actually Costs for a Townhouse Development in 2026

Pricing varies inside a predictable range. Here are the working numbers for metropolitan Melbourne in 2026, assuming a fully licensed contractor, full WorkSafe and EPA compliance, lawful disposal at authorised facilities, and a clean documentation pack at handover.

Scope	Typical 2026 Cost Range
Dual occupancy site demolition (single dwelling + garage + outbuildings + paths)	$22,000–$38,000
3-unit townhouse site demolition (single dwelling + larger garage + outbuildings + driveway + fencing)	$28,000–$48,000
4-unit townhouse site demolition (often two dwellings or a larger original home + multiple outbuildings)	$38,000–$70,000+
Hazardous materials survey	$450–$1,200
Class B non-friable asbestos removal (typical townhouse-site scope)	$4,000–$14,000
Class A friable asbestos removal (fire-damaged, severely weathered, or pipe lagging present)	2–4× equivalent Class B rate
Asbestos-contaminated soil management	$80–$180 per m³
Independent asbestos clearance certificate	$300–$900 (larger sites up to $1,500)
Swimming pool decommissioning and removal	$8,000–$22,000 (if present)
Section 29A demolition consent	$96.66 (statutory, 2025–26)
Asset protection permit and bond	$323–$465+ permit; bond $0–$10,000+ depending on council
Service disconnection coordination	usually included in scope; provider fees vary
EPA Waste Tracker administration	usually included in scope; tonnage costs passed through
Site grading to FFL	typically included in scope on a properly written quote

What pushes a project up the range:

Inner-east or bayside location — heritage assessment, higher asset protection bonds, slower council turnaround, more careful machine work next to neighbours
Two existing dwellings on the site (common on battle-axe lots and corner sites being developed as 4 units)
Heavy asbestos load — pre-1990 dwelling with full cement-sheet cladding, asbestos roofing on the garage, fibro fences, vinyl floor tiles
Pool, spa or large outbuildings
Tight access — narrow shared driveways, single-vehicle frontage, mature street trees, overhead wires limiting machine size
Sloping site with retaining walls or significant cut-and-fill
Tree protection conditions under your planning permit that constrain machine positioning
Contamination history — former service station, dry cleaner, market garden, industrial use, fire damage

What sits a project at the lower end:

Outer-growth corridor location (Wyndham, Casey, Cardinia, Melton, Hume) — faster Section 29A turnaround, lighter heritage footprint, lighter asbestos profile, simpler asset protection
Single-storey post-1990 dwelling with minimal outbuildings
Direct vehicle access to multiple boundary lines
Flat site with no retaining walls
No pool

The deeper cost framework is in The Cost of Asbestos Removal in Melbourne and Why It Varies.

Realistic Timelines for a Townhouse Development Demolition

End-to-end (from demolition contract signing to build-ready handover), realistic 2026 timelines:

Non-heritage outer-growth corridor townhouse site (Wyndham, Casey, Melton, Cardinia, Hume) — 8–10 weeks
Non-heritage middle-ring townhouse site (Glen Eira, Whitehorse, Manningham, Banyule, Maribyrnong, Brimbank) — 10–12 weeks
Inner-east non-heritage townhouse site (Boroondara, Stonnington, Bayside non-heritage pockets) — 11–14 weeks
Heritage Overlay townhouse site (Yarra, Stonnington, Boroondara, Bayside, Port Phillip, Hobsons Bay heritage zones) — 5–8 months, driven by planning permit timeline
Larger 4-unit site with two existing dwellings — add 2–3 weeks to the relevant baseline
Pool decommissioning required — add 1–2 weeks
Fire-damaged property — add 2–4 weeks for Class A asbestos and contaminated-soil work

A key thing for small developers to understand: the on-site demolition itself is the fastest part of the project. Even for a 4-unit site with two dwellings, the physical demolition is usually done in 5–10 working days. The rest of the timeline is council approvals, service disconnections, asbestos removal, and the site preparation tail. The full breakdown is in From Quote to Cleared Site: A Realistic Demolition Timeline in Melbourne and How Long Does It Take to Demolish a House in Melbourne?.

Where Melbourne’s Small-Developer Townhouse Activity Is Actually Happening

Townhouse infill activity isn’t evenly spread across Melbourne. The work concentrates in recognisable belts, each with its own profile of existing housing stock, council approach, asbestos load and developer-friendly (or developer-hostile) infrastructure.

Outer-Growth Corridor (Wyndham, Casey, Cardinia, Melton, Hume)

Tarneit, Werribee, Point Cook, Hoppers Crossing, Truganina, Cranbourne, Berwick, Narre Warren, Pakenham, Officer, Melton, Caroline Springs, Sunbury, Craigieburn. Generally the simplest demolition pathway in metropolitan Melbourne. Light heritage footprint, faster Section 29A turnaround, lighter asbestos load (most stock is post-1990), and reasonably efficient asset protection frameworks. Most demolitions here are single-storey 1990s–2000s homes being replaced with 2–3 unit townhouse projects on standard-sized lots. Allow 8–10 weeks end-to-end. The asset protection bonds are lower (Wyndham at around $323; Hume at $465); Casey runs a security bond model with refund inside 28 days of clean final inspection.

Middle-Ring North (Merri-bek, Darebin, Banyule, Whittlesea)

Brunswick, Coburg, Pascoe Vale, Northcote, Thornbury, Preston, Reservoir, Heidelberg, Bundoora, Ivanhoe. The classic 1950s–1980s asbestos belt — almost every demolition will have full Class B asbestos scope on eaves, fences, garage sheets, vinyl tiles and switchboard backing boards. Heritage Overlay coverage is patchy but genuine in pockets of Northcote, Thornbury, Brunswick East and Heidelberg. Asset protection bonds sit at the moderate end. Timelines typically 10–12 weeks.

Inner-West (Maribyrnong, Hobsons Bay, Brimbank-east)

Footscray, Yarraville, Seddon, Newport, Williamstown, Maribyrnong, Sunshine. Heavy 1950s–1970s asbestos load on the existing housing stock; Heritage Overlay coverage tighter than developers often expect in Yarraville, Seddon and Williamstown. Former industrial parcels (particularly around Footscray and Maribyrnong) can trigger environmental site assessment requirements that sit outside a standard demolition scope. Allow 10–13 weeks and budget for a Phase 1 ESA on any parcel with industrial history.

Inner-East and Bayside (Boroondara, Stonnington, Bayside, Glen Eira)

Hawthorn, Kew, Camberwell, Balwyn, Toorak, Armadale, Malvern, South Yarra, Prahran, Brighton, Hampton, Sandringham, Beaumaris, Caulfield, Bentleigh, McKinnon, Ormond. The trickiest belt for small developers. Heritage Overlay coverage is dense in many streets; asset protection bonds are the highest in metropolitan Melbourne (often $5,000–$15,000+ for a townhouse development); council Section 29A turnaround is slower than outer-growth councils because of higher application volumes and stricter plan checking; and mature street trees regularly come with separate tree protection conditions on demolition permits. Timelines typically 11–14 weeks for non-heritage and 5–8 months for heritage-affected projects.

Inner-City Heritage Belt (Yarra, Melbourne, Port Phillip)

Fitzroy, Carlton, Collingwood, Richmond, Princes Hill, North Melbourne, East Melbourne, South Melbourne, Albert Park, Middle Park, St Kilda. The most heritage-dense belt in Australia outside of central Sydney. Townhouse infill here is dominated by facade retention projects rather than full demolitions. Engineered temporary works, dilapidation surveys of adjoining properties, party-wall engineering reports and adjoining-owner agreements all become routine cost lines. Allow 5–8 months and engage a structural engineer early. The framework is in our Partial Demolition: When Removing Half a House Makes Sense in Melbourne guide.

South-East Middle Ring (Glen Eira, Kingston, Monash, Whitehorse, Manningham)

Bentleigh East, Carnegie, Murrumbeena, Hughesdale, Oakleigh, Clayton, Mount Waverley, Glen Waverley, Mentone, Mordialloc, Cheltenham, Box Hill, Doncaster, Templestowe, Blackburn. A strong townhouse infill market on 1960s–1980s housing stock — solid Class B asbestos profile, generally efficient council process, asset protection in the moderate range. Timelines typically 10–12 weeks.

Outer East and Yarra Ranges

Ringwood, Croydon, Bayswater, Knox, Lilydale. Mostly straightforward townhouse infill on 1970s–1990s stock, with asset protection at the lower end of metropolitan rates. The bushfire-affected sections of the Yarra Ranges add complications when fire damage is in the property’s history — fire often turns previously bonded asbestos into friable material requiring a Class A licensed removalist and contaminated-soil management. We covered this scenario in Bushfire-Damaged Property Demolition: The Victorian Process.

The Six Demolition Decisions That Most Often Cost Small Developers Money

After running the demolition phase on dozens of small townhouse developments, the same six judgment calls keep showing up as the difference between a project that ran clean and one that didn’t.

1. Accepting the Builder’s “Demolition Allowance” Instead of a Separate Quote

Many builders’ contracts include a $10,000–$15,000 “demolition allowance” — usually based on a quick estimate, often without a physical site inspection, almost never including asbestos, asset protection bonds, or site preparation to FFL. When the demolition tender comes in at $32,000 because the existing dwelling has eaves and garage cladding and vinyl tiles and a fibro fence, the variation lands on the developer.

The fix: Get an independent, line-itemised demolition quote before you sign the builder’s contract. Insist on a physical site inspection. Treat the demolition scope as its own contract, not a line item.

2. Lodging Approvals Sequentially Instead of in Parallel

Section 29A, the four service disconnections, the asset protection permit, the hazardous materials survey and the asbestos notification all run on their own clocks. Done in series, they take 12 weeks. Done in parallel, they take 4–6 weeks.

The fix: Engage a demolition contractor who acts as your authorised agent across the entire approvals stack and lodges everything within 48–72 hours of contract signing.

3. Underestimating the Asbestos Scope

A pre-1990 dwelling on a townhouse site is almost always carrying $4,000–$14,000 of Class B asbestos removal. Quotes that cite $1,500–$2,500 for “site asbestos” are pricing a different, non-compliant job — usually one that hopes the material can be quietly buried in the rubble. The day the EPA inspector or the Registered Building Surveyor catches it, you’re looking at a Class A clean-up at 3–4 times the original Class B cost.

The fix: Demand a separately itemised asbestos line with named licence class, named WorkSafe notification reference, named EPA-licensed disposal facility, named independent licensed assessor, and per-square-metre rate. Verify the WorkSafe asbestos removal licence on the live register before signing.

4. Treating Site Preparation as the Builder’s Problem

The grey zone between “demolished” and “build-ready” is where small-developer projects bleed days. If your demolition contract says “demolish existing structures” but is silent on slab removal, footing removal, fence post concrete, grading to FFL, re-pegging, geotechnical scheduling and the documentation pack — your builder will charge variation rates to do all of it.

The fix: Write the site-preparation scope into the demolition contract explicitly. Use the checklist in our Site Preparation After Demolition guide as the spec.

5. Skipping the Independent Asbestos Clearance Certificate

A clearance certificate must be issued by an independent licensed asbestos assessor — not the removalist. The independence is the entire point. A few contractors will offer to “self-certify” to save money. That certificate is non-compliant, your RBS will reject it, your builder won’t start, and the project goes back two weeks while an independent assessor is engaged.

The fix: Name the independent licensed assessor in the demolition contract at the quote stage. Verify they’re not commercially connected to the removalist. Sight the certificate at handover.

6. Letting the Demolition Contractor Disappear at Handover

Your conveyancing solicitor will ask for the documentation pack at every unit sale 12–18 months later. The asset protection bond doesn’t release until council final inspection. The EPA Waste Tracker reconciliation has to balance. The asbestos clearance certificate has to be on file. A contractor who packs up and stops returning calls the day after the rubble leaves is leaving you holding the bag on six different documentation streams.

The fix: Specify in the contract that the documentation pack — every permit, every notification, every clearance certificate, every weighbridge docket, every invoice — is handed across in physical and digital form before final payment. Hold a documentation-completion retention until it’s all received.

How Demolition Coordinates With Your Civil Works and Builder

On a small townhouse development, demolition usually sits between two other workstreams: the planning and design phase (architect, town planner, landscape architect) that precedes it, and the civil and structural phase (civil contractor, structural engineer, builder) that follows it. Done well, the three handovers are clean. Done badly, the seams are where variations live.

Three practical principles help.

Decide who owns the demolition contract before you sign the builder. Some builders prefer to receive a fully cleared, fully levelled site from a separately contracted demolition specialist (our most common arrangement on small developer projects). Others prefer to handle demolition through their own subcontractor and absorb site preparation into the early stages of the build. Either model works — but mixing them halfway through is where projects haemorrhage time and money. Lock the answer in before any deposits go through.

Get the structural engineering inputs before site grading. Your structural engineer will have a preferred Finished Floor Level, slab type and edge beam design for the new units. Those decisions should be sketched out — even in draft — before the demolition contractor grades the block. A site graded to “level” without knowing the engineering target is guessing; on most sites that guess is wrong, and the regrade lands on the developer.

Time the geotechnical investigation correctly. Geotech done before demolition tells you about the old soil under the existing slab. Geotech done after the slab and footings are removed tells you about the soil that will actually carry your new units. Schedule it for the cleared block, not the existing dwelling.

For the broader handover framework, see our Site Preparation After Demolition guide.

Frequently Asked Questions

What is “demolition for townhouse developments” in Melbourne?

Demolition for townhouse developments is the structural and regulatory work required to clear an existing residential site so that a small multi-unit project — typically 2–4 townhouses on a single existing residential lot — can be built. In practice it usually means demolishing one existing dwelling plus garages, sheds, fences, driveways, paths, and sometimes a pool or granny flat, then preparing a build-ready site for the new construction. It runs under the same statutory framework as a single-house knock-down rebuild (Building Act 1993, OHS Act 2004 and OHS Regulations 2017, Environment Protection Act 2017), with tighter coordination, larger documentation requirements and a greater focus on build-ready handover.

How much does demolition cost for a townhouse development in Melbourne in 2026?

For a typical dual-occupancy site (one existing dwelling, garage, outbuildings, paths and fencing), expect $22,000–$38,000 for a fully compliant demolition with site preparation. For a 3-unit townhouse site, $28,000–$48,000. For a 4-unit site with one or two existing dwellings, $38,000–$70,000+. Asbestos removal is itemised separately at $4,000–$14,000 for a typical Class B (non-friable) scope. Pool decommissioning, if present, adds $8,000–$22,000. Inner-east and heritage-affected sites sit at the upper end; outer-growth corridor sites sit at the lower end.

How long does demolition take for a townhouse development in Melbourne?

End-to-end from contract signing to build-ready handover: 8–10 weeks for a non-heritage outer-growth corridor site, 10–12 weeks for a middle-ring site, 11–14 weeks for an inner-east non-heritage site, and 5–8 months for a Heritage Overlay site driven by the planning permit timeline. The on-site demolition itself is the fastest part — typically 5–10 working days even on a multi-asset 4-unit site. The rest is council approvals, asbestos removal, service disconnections and site preparation.

Do I need a planning permit to demolish on a townhouse development site?

Sometimes. A planning permit for demolition is required where the site is affected by a planning control that triggers it — most commonly a Heritage Overlay, but also sometimes a Neighbourhood Character Overlay, a Significant Landscape Overlay, or a covenant on title. If a planning permit is required, it must be granted before Section 29A demolition consent can be issued. Note that the planning permit for the new townhouse development is separate from any planning permit for demolition — you may need both, and they’re assessed under different criteria.

Do I need Section 29A consent to demolish on a townhouse development site?

Almost always yes. Section 29A consent is required where either the 50% volume test is met (you’re demolishing more than half the volume of the existing building, counting any demolition completed or permitted in the previous three years) or any street-facing facade is being demolished or altered. On a townhouse development site where the existing dwelling is coming down entirely, both tests are easily met. The statutory fee is 5.75 fee units = $96.66 for 2025–26. Without Section 29A consent, your Registered Building Surveyor cannot issue the building permit for demolition.

What asset protection bond should I budget for on a townhouse development?

Asset protection permits range from around $323 in Wyndham to $465+ in Hume. Inner-east councils (Boroondara, Stonnington, City of Melbourne, Yarra, Port Phillip) charge a permit fee plus a separately calculated security bond, often $2,000–$10,000+ for a townhouse development site with multiple street frontage, mature street trees, kerb risk and footpath risk. The bond is refundable on a clean final inspection — usually within 28 days. Budget for the higher end on inner-east projects; outer-growth corridor sites generally sit at the lower end.

Does my existing dwelling have asbestos if it was built between 1950 and 1989?

Almost certainly yes. Australia was one of the heaviest per-capita users of asbestos in the world from the 1940s to the late 1980s, and Melbourne’s pre-1990 housing stock is essentially a four-decade fossil record of asbestos cement — eaves, fences, cladding, Super Six roofing, vinyl tiles, bathroom linings, Zelemite electrical backing boards. The question is where and how much, not whether. A hazardous materials survey by an independent licensed assessor is mandatory before demolition under Part 4.4 of the OHS Regulations 2017. The pattern for each decade is in our Asbestos in 1950s–1980s Melbourne Homes guide.

Can I get a Class B asbestos removalist to remove friable asbestos?

No. A Class B licence covers non-friable (bonded) asbestos only — cement sheeting, eaves, vinyl tiles, fibro fences, asbestos cement roofing, electrical backing boards. Friable asbestos — pipe lagging, sprayed insulation, fire-damaged or severely weathered ACM, asbestos-contaminated soil — requires a Class A licensed removalist. On a townhouse development site, the vast majority of asbestos is non-friable and within Class B scope. Where friable material is present (fire damage, severely weathered ACM, pipe lagging in an older property), the work is sub-contracted to a Class A specialist. We hold a Class B licence in-house and partner with Class A specialists where friability requires it. The licence-class distinction is unpacked in Friable vs Non-Friable Asbestos: Demolition Melbourne.

Who is responsible for the asbestos clearance certificate?

The independent licensed asbestos assessor — not the removalist who did the work. The independence is the legal requirement, and the point: the clearance certificate confirms the work area is free of asbestos contamination, and that confirmation has to come from a party with no commercial interest in saying “yes”. The clearance certificate becomes part of the property’s permanent record, is required before any further works on the site, and is routinely checked by your builder’s site supervisor, your RBS, future unit purchasers’ conveyancers and insurers. A reputable Melbourne demolition contractor names the independent assessor they engage at the quote stage.

What documentation do I get at handover for a townhouse demolition?

A complete documentation pack should include: Section 29A demolition consent, building permit for demolition, asset protection permit and final inspection report, hazardous materials survey, asbestos register, WorkSafe asbestos removal notification reference, asbestos clearance certificate from the independent licensed assessor, EPA Waste Tracker records for every reportable priority waste movement, weighbridge dockets for every load leaving site, service disconnection certificates for all four utilities, public liability insurance certificate (with asbestos cover), and the demolition contractor’s WorkSafe licence and VBA registration documents. We hand the full pack across in both physical and digital form, and recommend keeping it for a minimum of 5 years.

What happens if I demolish without the right permits?

Penalties under the Building Act 1993 can run into tens of thousands of dollars per offence for individuals and significantly more for companies. WorkSafe and EPA penalties stack on top — EPA Victoria penalties under the General Environmental Duty can reach $1.8 million for companies. Council can issue stop-work orders, refer the matter for prosecution, require you to rebuild or restore the structure in some heritage cases, and refuse to issue future approvals on the site. Insurance won’t cover unpermitted demolition. Future unit sales become significantly harder once council records show illegal works. The cost of compliance is dramatically lower than the cost of non-compliance.

Can the demolition contractor lodge the council applications on my behalf?

Yes — and on most small developer projects, this is the most efficient model. A Section 29A application can be lodged by the property owner or an authorised agent, and demolition contractors with experience on developer projects routinely act as authorised agent for the full approvals stack — Section 29A, asset protection, the four service disconnections, the WorkSafe notification and the EPA Waste Tracker registrations. The planning permit for the new townhouse development is typically lodged by a town planner; the asset protection permit is usually lodged by the demolition contractor in their own name.

Should I sign the builder’s contract before the demolition contract?

Not without an independent demolition quote in hand. A builder’s “demolition allowance” — usually $10,000–$15,000 — is almost always lower than the real cost of a fully compliant demolition with asbestos removal, asset protection bond, EPA waste compliance and site preparation. Signing the builder’s contract before pricing the demolition independently leaves you exposed to a variation invoice the moment the real demolition tender lands. Get the demolition quote first, lock the scope, then sign the builder.
