Buying a Renovator in Brisbane: What to Check Before You Buy
A renovator can be one of the smartest ways into a good Brisbane suburb. You buy below the price of a finished home, add value through the work and end up with a property shaped around how you live.
It can also be one of the most expensive mistakes in property. The difference usually comes down to what you check before you sign. This guide covers the key checks.

Check the overlays first
Many of Brisbane’s most sought-after suburbs are covered by the traditional building character overlay, which generally protects homes built before 1947. It can limit demolition and shape what you can change at the front of the house. Flood, bushfire and other overlays can also affect what you can build and what it costs to insure. Look up any property on Brisbane City Council’s City Plan online before you get attached to a plan.
Know what you’re really buying
Structure. Stumps, termite damage, roof condition and sagging floors can turn a cosmetic job into a structural one.
Asbestos. Homes built before 1990 may contain asbestos in sheeting, eaves and flooring. Removal needs licensed contractors and adds cost and time.
Services. Old wiring, galvanised plumbing and outdated switchboards often need replacing.
Unapproved work. Enclosed verandahs, built-in underneaths and extensions done without approval can be costly to fix.
A thorough building and pest inspection is essential. For bigger projects, it’s worth getting early building and interior design advice on what the home can realistically become before you go unconditional.
Price the renovation before you buy
Most renovation budgets blow out because they were guessed, not priced. Get a builder or designer to walk through the property during your due diligence period and give you a realistic range. Include design, approvals, demolition, contingency and the cost of living elsewhere during the works.
Then do the sum: purchase price plus all costs should leave room below the value of a finished home in the same street. If it doesn’t, keep looking.
Approvals, licenses and insurance
Some renovations need only a building approval from a private certifier. Others, especially in character areas, need council approval too. In Queensland, residential building work over $3,300 generally needs a licensed contractor and home warranty insurance, as the QBCC explains. Check every licence before you sign.
On larger projects, an independent construction project manager can coordinate designers, consultants and trades, and keep the budget and program on track.
Renovate or rebuild?
If the house isn’t protected and the structure is poor, a knockdown rebuild may cost little more than a major renovation and give a better result. New homes must meet Queensland’s Modern Homes standards for energy efficiency and accessibility. If the property is or will be an investment, note that from 1 July 2027 a one-for-one rebuild won’t count as an eligible new build for negative gearing.
Frequently asked questions
Is it cheaper to renovate or knock down and rebuild?
Renovating usually costs less upfront, but major renovations on older homes can approach the cost of a rebuild once hidden problems are found. Get both options priced before deciding.
Does a knockdown rebuild count as a new build for tax?
Only if it increases the number of dwellings on the land, under the draft rules. Replacing one house with one new house doesn’t qualify.
Do I need home warranty insurance?
In Queensland, home warranty insurance applies to residential building work over $3,300 done by a licensed contractor.
Do new homes have to meet 7-star energy ratings?
In Queensland, most new houses and townhouses must achieve 7 stars for thermal performance since 1 May 2024, with lower requirements for some eligible homes.
Our View
The right answer depends on the site, the budget and what the property needs to do for you. What matters most is making the decision with the full picture: planning, standards, tax, cost and end value. Projects go wrong when that work is skipped at the start.
