Home Renovations
Home Renovations near you
A home renovation is work on a house you already own: reworking rooms, replacing what has worn out, opening up a plan that no longer suits the household. Australian housing stock makes that a very wide category. A weatherboard cottage on stumps, a post-war brick veneer on a slab, a Queenslander with living space underneath and a 1990s project home all renovate differently, and the first useful conversation with a builder is about what is actually behind the linings rather than what the finished room should look like.

Two separate approvals sit behind most jobs and they come from different places. Planning approval is about what you are allowed to build on the land, and it is set by state planning policy and your council. Building approval is about whether the construction satisfies the National Construction Code, and depending on the state it comes from a private certifier, a registered building surveyor or the council itself. Small internal work often needs neither. Anything structural almost always needs the second, and frequently the first as well.
The age of the house is the other variable that changes everything. Consumer Affairs Victoria states the obligation plainly: as the home owner it is your responsibility to make sure the planning and building permits are obtained, whether you get them yourself or ask your builder to. In a house built before the late 1980s, add an asbestos check to that list before anyone pulls a sheet off a wall.
Cosmetic, fit-out, services and structural work: which kind of renovation is yours
Almost every argument about a renovation quote comes from the two parties picturing a different category of work. Sorting the job into these bands before you ask for prices tells you which trades are involved, whether an approval is needed and how much of the cost is buried where you cannot see it.
- Cosmetic work — painting, new floor coverings, new door furniture — changes how a room reads without touching structure, services or waterproofing, and is the only band that is genuinely predictable.
- Fit-out work replaces fixed elements such as cabinetry, benchtops, wardrobes and built-in storage, and usually needs a carpenter or cabinetmaker plus a licensed electrician for any new point.
- Wet-area work disturbs a shower, bath surround or laundry floor, which brings in licensed plumbing and the Code's waterproofing requirements and takes the job out of the finishes category entirely.
- Services work — rewiring, switchboard upgrades, gas alterations, new drainage — is licensed everywhere in Australia whatever it costs, and each licensed trade should leave a compliance certificate behind.
- Structural work removes or alters something that carries load: a wall, a roof line, a lintel over a new opening in masonry. It needs an engineer's design and a building approval.
- Reconfiguration that changes the number of bedrooms, or creates a secondary dwelling, is a planning question before it is a building one, and the answer comes from your council.
- Repair after storm, flood or termite damage is its own category, because the insurer's scope, the builder's scope and the approval pathway all have to line up.
Exempt development, complying development and the building permit: the approval pathways by state
New South Wales sorts every proposal into one of three pathways. Minor work can be exempt development and needs no consent at all. Work that meets every development standard in the state's exempt and complying development policy can go through complying development, which the Department of Planning says covers alterations and additions to a house among other things, and which a council or an accredited certifier can determine in as little as twenty days against an average determination time for a development application of seventy days. Houses built to the NSW Housing Pattern Book have a ten-day pathway of their own. Anything that misses a standard goes to the council as a development application.
Victoria splits the question in two and puts the responsibility on the owner. Consumer Affairs Victoria states that before you start to build a house, or do your home extension or renovation, you or your agent must find out from the local council whether you need a planning permit, and that it is your obligation as the owner to make sure planning and building permits are obtained. The building permit comes from a registered building surveyor, and your builder cannot appoint that surveyor on your behalf — you appoint one yourself, or you use the municipal building surveyor at the council. Queensland runs its own system, in which a building development approval is issued by a building certifier before construction starts.
New South Wales adds a third certificate that catches renovators by surprise. The NSW Planning Portal states that if you are building a new home, undertaking renovations of fifty thousand dollars or more, or installing a pool or spa of more than forty thousand litres, you will need a BASIX certificate, which sets targets for water, energy use and thermal comfort. It is worth finding out early whether your job crosses that line, because BASIX commitments can change the glazing, insulation and hot water decisions you would otherwise have made on price alone.
How a multi-room renovation runs, from scope to final inspection
Finding the right builder starts with writing the brief once rather than four times. LokalMatch takes that brief — rooms, scope, postcode, rough timing — and puts it in front of builders who work in your area, who then contact you themselves. Those businesses pay for the enquiries they receive, and that is the whole of the platform's revenue. It builds nothing, prices nothing, and screens, scores or endorses no one, so the register check, the insurance certificate and the reference calls remain your job.
The sequence below is the one most Australian renovations follow. The useful thing about writing it down is that it shows you the hold points — the moments where something has to be inspected, certified or signed before the next trade can start — and those are where a job slips if nobody is watching them.
- Scope and drawings first, so that every builder prices the same job and variations later are real changes rather than misunderstandings.
- Hazardous materials survey on any house built before the late 1980s, done before demolition rather than during it, so removal can be planned and priced.
- Planning approval where it is needed, then the building approval from your certifier, surveyor or council.
- Demolition and strip-out, which is the point where the real condition of framing, wiring and drainage finally becomes visible.
- Structural work and rough-in: engineer-designed beams and lintels, then plumbing, electrical and any gas alterations, each inspected before it is covered up.
- Waterproofing to wet areas, left to cure as the membrane manufacturer specifies before anything is tiled over it.
- Linings, tiling and joinery, then fit-off, and finally the compliance certificates and the certifier's or surveyor's completion paperwork.
What actually moves the price of an Australian renovation
Prices are set by the market and by your particular house, and no honest guide can quote them. What a guide can do is tell you which variables move a quote most, so that when two prices differ you can find out why instead of guessing.
- Access: a narrow inner-city block with no side access, a steep site or an upper floor in a walk-up all mean materials and waste move by hand.
- Whether the services move. Leaving the sink, the cooktop, the toilet and the shower waste where they are removes several licensed trades' worth of work from the job.
- Structure: every wall you take out has to be assessed, and the ones that turn out to be load-bearing bring in an engineer, a beam and a building approval.
- Lead times on imported tapware, tiles and appliances, which can hold a trade off site and push a fixed-price job past its contract dates.
- Prime cost and provisional sums, which are allowances rather than prices — the number in the contract is a placeholder and the final account reflects what was actually chosen.
- Waste: tip fees, skips and, where asbestos is present, disposal at a facility licensed to receive it.
- Strata or body corporate approval in an apartment, which can dictate work hours, floor coverings and any change to common property.
- Whether you live in the house during the work, which slows a builder down and is usually reflected somewhere in the price.
Asbestos, hidden services and the variations that eat a renovation budget
Asbestos is the one that has to be planned rather than discovered. SafeWork NSW says a friable asbestos removal licence is required to remove any amount of friable asbestos, and a non-friable asbestos removal licence is required to remove more than ten square metres of non-friable asbestos, and it recommends using a licensed professional for any quantity at all. Its advice on doubt is the right rule for homeowners: if you think it is asbestos, treat it like it is. In the same era of housing, eaves linings, wet-area sheeting, vinyl floor backing and fences are the usual places it turns up.
- Wiring that predates the current standards, found only once the linings are off, and a switchboard with no room for the circuits the new plan needs.
- Drainage that does not run where the plan says it runs, which matters most when a wet area is being relocated.
- Existing waterproofing that was never compliant, discovered when a wall sheet comes off wet.
- Timber damage from termites or long-term leaks, which turns a cosmetic job into a structural one overnight.
- Variations agreed verbally on site and never written down, which is the single most common cause of a disputed final account.
- Provisional sums that were set low to make an early quote look competitive, so the price climbs as real selections are made.
- A scope that grows room by room until the job crosses an approval threshold nobody went back and checked.
What covers you after the builder leaves: NSW home building compensation and the equivalents elsewhere
Residential builders' insurance is a state scheme that pays the homeowner when the builder cannot put a defect right — because they have died, disappeared, become insolvent or lost their licence. New South Wales is the clearest worked example. icare, which runs the Home Building Compensation Fund and is the only insurer of it in the state, says cover is required by law for most residential building work valued at more than twenty thousand dollars unless an exemption applies, and that your builder must give you evidence of cover before work starts or before you pay any more money under the contract, including a deposit.
The cover is time-limited and the periods are worth knowing before you sign. icare sets them out as up to six years from completion for major defects, up to two years from completion for other defects, and up to twelve months from when work stopped or failed to start for incomplete or non-started work. Other states and territories run comparable schemes under different names — home warranty in Queensland, domestic building insurance in Victoria, home indemnity insurance in Western Australia — with their own thresholds and their own periods, so look up the figures for the state the work is in rather than assuming the NSW ones travel.
Separately from insurance, statutory warranties are implied into residential building contracts by state law and cannot be signed away, and the consumer guarantees in the Australian Consumer Law sit over the top of both. Keep every certificate, the contract, the approved plans and the variation paperwork together; if you ever need to make a claim or sell the house, that folder is the evidence.
Signs the renovation you are planning is really a building project
- You are thinking about removing a wall, and nobody has yet established whether it carries load.
- The plan moves a kitchen, bathroom or laundry to a different part of the house, which relocates drainage and usually the switchboard load with it.
- The work crosses your state's value threshold for a licensed contractor, a prescribed written contract and residential builders' insurance.
- In New South Wales, the spend reaches the point where a BASIX certificate is required and thermal performance becomes part of the design.
- The house dates from before the late 1980s and sheet materials will be cut, drilled or removed.
- More than three trades have to be sequenced, and one of them waiting would stop the whole job.
- You want a single party answerable for defects afterwards rather than several trades pointing at one another.
Home Renovations: frequently asked questions
Do I need council approval to renovate inside my own house?
It depends on the state and on what you are touching. Purely internal, non-structural work often needs no planning approval, but building approval is a separate question and structural work almost always needs it. In New South Wales, work that meets every standard in the state's exempt and complying development policy can be exempt or go through complying development, which a council or an accredited certifier can determine. In Victoria you must find out from the council whether a planning permit is needed, and a registered building surveyor issues the building permit. Queensland uses a building development approval from a building certifier.
Who appoints the building surveyor or certifier — me or my builder?
You do. Consumer Affairs Victoria states that your builder cannot appoint a private building surveyor on your behalf; you appoint one, or you use the municipal building surveyor at your council. The reason is independence: the person checking the work should not be chosen by the person doing it. Other states take the same approach to the appointment of a principal certifier, so treat a builder who offers to bring their own as a question rather than a convenience.
When does a renovation in New South Wales need a BASIX certificate?
The NSW Planning Portal says a BASIX certificate is needed if you are building a new home, undertaking renovations of fifty thousand dollars or more, or installing a pool or spa of more than forty thousand litres. BASIX sets targets for water, energy and thermal comfort, and the commitments it generates become conditions of your approval, so they need to be settled while the design is still on paper rather than after the windows have been ordered.
Can I remove asbestos sheeting myself?
SafeWork NSW says a licence is required to remove any amount of friable asbestos, and a non-friable asbestos removal licence is required to remove more than ten square metres of non-friable asbestos — and it recommends using a licensed professional for any amount. Disposal has to go to a facility licensed to receive it, which is one reason quotes that include asbestos removal look different from ones that do not. If you are unsure what a material is, assume it is asbestos and have it identified before anything is cut or drilled.
How long am I covered for defects after the work is finished?
In New South Wales, icare's Home Building Compensation Fund cover runs up to six years from completion for major defects, up to two years from completion for other defects, and up to twelve months from when work stopped or failed to start for incomplete work. Statutory warranties implied into the contract by state law run alongside that. Other states set their own periods under their own schemes, so check the ones that apply where the work is being done and keep the completion paperwork, because the clock usually runs from that date.
What should I do about variations once work has started?
Get every one of them in writing before the work is done, with the change described, the price and any effect on the completion date. Verbal agreements made on site are the most common cause of a disputed final account, and they are also the hardest to resolve afterwards because both parties genuinely remember the conversation differently. If a variation changes something structural or takes the job outside the approved plans, the certifier or building surveyor needs to know about it too.

What affects the cost of home renovation
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Size and scope of the project
- Structural changes, such as moving or removing walls
- Plumbing, electrical and HVAC work involved
- Finishes and materials chosen
- Design, drawings and permits
- Condition of the existing house once it's opened up
- Access to the site and the timeline
How to compare renovation contractors before you hire
- Look for a contractor who has finished projects similar in size and type to yours, and ask to see them.
- Get a written contract with the scope, the payment schedule, the timeline and how changes will be priced.
- Ask who will manage the job day to day and how often you'll get updates.
- Check that they carry liability insurance and workers' compensation coverage, and that their trades are licensed where required.
- Compare quotes on the same scope, and ask what each one leaves out.
- For structural changes, make sure an engineer or designer is involved where needed.
Questions to ask renovation contractors before you hire
- Who will pull the permits, and who will be there for inspections?
- Which parts of the job will you do yourselves, and which will go to subcontractors?
- How do you handle change orders and unexpected problems once walls are open?
- What is the payment schedule, and what is each payment tied to?
- Can you show me proof of liability insurance and workers' compensation coverage?
- What warranty do you offer on your workmanship, and is it in writing?
- Can I speak with a few of your recent clients?
Home renovation permits and local rules
Some home renovation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
