What this site says, and where it comes from
Sydney Building Lawyers is an informational website about building and construction law in New South Wales. This page sets out what it covers, the official sources behind it, and what it leaves out on purpose.
General information, not legal advice. This page sets out how the law generally applies. It does not take account of your circumstances, and you should get advice about your own situation before acting on it. The official sources this page is written from are listed on it; where they differ from anything here, they are the authority.

There is a great deal of building law online and much of it never says where it got anything. This page says. It is deliberately short on adjectives, because the things worth knowing about a website like this one are checkable.
Everything here is general information about the law in New South Wales. It is not legal advice and it cannot be, because it knows nothing about your contract, your site or your dates. Reading a page does not make you a client.
The law these pages are about
Most building disputes in New South Wales run on a small number of statutes. Which one matters to you depends on who you are, what kind of work was done, and whether the argument is about money or about the work itself.
These pages stay on that ground. They explain the mechanism — what the law sets up, what it asks of each side, and what usually happens next — rather than predicting what a tribunal would do with your matter.
- Home Building Act 1989 (NSW). Statutory warranties on residential building work: that the work is fit for its purpose, carried out diligently, finished in a reasonable time and in line with the contract. The Act also sits behind the requirement for home building compensation cover.
- Building and Construction Industry Security of Payment Act 1999 (NSW). A fast statutory route to progress payments for work already done: a payment claim, a payment schedule in reply, and adjudication where the amount is still in dispute.
- Design and Building Practitioners Act 2020 (NSW). Registration, regulated designs lodged on the NSW Planning Portal, and declarations that building work complies with the Building Code of Australia, for practitioners working on regulated buildings.
- The contract itself. Variations, extensions of time, defects liability and termination are usually decided by what the parties signed, read together with the legislation above.
The guides take three of these apart in more detail: before you sign, what makes a payment claim valid, and statutory warranties and who can rely on them.
How long a warranty claim lasts
Statutory warranties do not run forever. For contracts signed on or after 1 February 2012, proceedings to enforce them have to be started within six years for a major defect and two years for any other defect, measured from completion of the work. The exact deadline in a particular matter depends on the contract and on the facts, so it is worth having it assessed rather than assumed.
So the first question in a defect matter is usually not whether the work is bad. It is which side of that line the defect falls on, and whether the period has already run. Those two things decide whether a statutory warranty claim is still in time; other remedies can run to different limits.
Whether a particular problem counts as a major defect is a question about the building and about the Act. It is worth asking early, because the answer can change a two year window into a six year one, or the other way round.
If a warranty period might be close to expiring, do not wait until you have gathered more evidence. Raise it first. Gathering can continue afterwards. Where loss becomes apparent in the last six months of the period, NSW Government guidance describes a further six months after the period ends to enforce the warranty; whether that applies depends on the facts, so it is better not to have to rely on it.
Why payment disputes move so fast
The Security of Payment legislation exists so that contractors and subcontractors are paid for work already done without waiting for the whole job to be argued out. It does that by putting short, strict time limits on both sides.
A payment claim is served. The other side replies with a payment schedule that says what it proposes to pay and, if that is less than the amount claimed, all of the reasons why. If the amount is still disputed, the claimant may apply for adjudication.
The penalty for silence is the part people are caught by. A respondent who does not give a payment schedule in time can become liable for the full amount claimed, and can be shut out of raising a defence based on the contract or a cross-claim.
You will not find the day counts on this page. They depend on the kind of claim and on the contract, and a number read off a website is exactly how a right gets lost. The NSW Government’s Security of Payment pages hold the current ones, and they are the pages to read.
If a payment claim has arrived, write down the date it arrived before you do anything else. Everything after that is counted from it. See Security of Payment.
Where a building dispute is decided
Home building matters are heard in NCAT’s Consumer and Commercial Division. That list covers the everyday residential disputes rather than only the large ones.
Before NCAT will accept most home building applications, the dispute has to have been referred to NSW Fair Trading first, and evidence of that investigation has to be attached unless the matter is exempt. NCAT lists the exemptions, and they include an appeal against an insurer’s decision, claims involving an unlicensed contractor, and matters where the time for lodging a claim is due to expire within three months. Assume the referral applies to you until you are told otherwise.
Larger matters, commercial construction, and claims that are not home building at all belong in the courts instead. Which applies depends on the claim and on the amount, not on preference.
- Payment for home building work or services
- Incomplete or defective home building work
- Specialist work — electrical, plumbing, gasfitting, air conditioning
- Damage caused to other structures by home building work
- Appeals against an insurer's decision on a claim
Building Commission NSW runs a free complaint handling service for building work, and can refer a matter to a building inspector. Many disputes end there, before anything is filed anywhere.
How these pages are written
Every page carries the date it was last updated and the official sources it relies on. Those sources are NSW legislation, the courts and tribunals, and NSW government agencies. No commercial site is cited here, and no other law firm’s site is cited here.
Where a figure moves — a dollar threshold, a number of days, a fee — the mechanism is described and you are sent to the official page that holds the current number. That is deliberate. An out-of-date figure on a legal website is worse than no figure at all, because it looks reliable.
If a page here and an official source disagree, the official source is right. We would like to know about it: tell us and the page gets corrected.
What you will not find here
Some things are missing on purpose.
- Fees. No figures and no ranges. What a building matter costs depends on the contract, the size of the claim and how hard it is fought, so a number published here would tell you nothing about your own matter. Ask instead.
- Outcomes. No success rates, no case studies, no guarantees. A tribunal or a court decides the matter, and nobody can tell you in advance what it will decide.
- Reviews and testimonials. None are published here.
- Timeframes. How long a matter takes depends on the list it is in, the evidence and the other side. A figure for that would be a guess.
- Suburb pages. The Home Building Act applies the same way in Parramatta as in Penrith. There is nothing honest to write that changes with the postcode.
If something you needed is missing, or a page is hard to follow, say so. That is more useful than a compliment.
Checking a lawyer in New South Wales
You do not have to take any of this on trust, and you should not take it on trust from any legal website, including this one.
A solicitor in New South Wales may only practise while holding a current practising certificate. The Law Society of NSW issues those certificates and publishes a list of the solicitors who hold one, so a name can be checked before you hand over your contract and your correspondence. Engaging someone who does not hold one generally leaves you with very little if something goes wrong.
Complaints about a lawyer in New South Wales are dealt with by the Office of the NSW Legal Services Commissioner, under the Legal Profession Uniform Law. It is independent of any firm. Our complaints page explains how to raise something first, and where to take it if that does not settle the matter.
Do this for any building lawyer you are considering. It takes a few minutes and it is the one check nobody can talk you out of.
Privacy, terms and accessibility
Our privacy policy sets out what personal information is collected through this website, how it is handled and how to ask for access to it. The terms of use cover the website itself.
Our accessibility page sets out the standard this site works to, and how to ask for the same information in another format if any part of the site is hard for you to use.
