Step-by-Step Guide to Filing a Complaint with the Building Commission WA

Dealing with a builder who’s done the wrong thing is exhausting in a way that’s hard to describe unless you’ve been through it. You’ve paid money, often a significant amount, and what you got in return is either shoddy work, unfinished work, or a contractor who has completely gone quiet on you. If you’re in Western Australia and you’ve hit that wall, the Building Commission Perth is where you need to start. Here’s exactly how to go about it.

Know What They Actually Deal With

This part matters more than people realise. The Commission handles complaints about registered building practitioners – think licensed builders, building surveyors, painters registered under the relevant scheme. If your issue is defective work, incomplete work, or a contractor who behaved unprofessionally or breached their obligations, you’re in the right place.

But here’s where a lot of people waste weeks going in circles: payment disputes aren’t handled here. If your contractor owes you a refund or you’re arguing over invoices, that’s a completely different process. Getting clear on this before you start saves you a lot of frustration.

Pull Together Every Document You Have

Most complaints don’t fail because the work wasn’t defective – they fail because the person filing couldn’t back up what they were saying. The Commission needs evidence, not just a story.

Dig out your signed contract, any written quotes or variations, invoices, bank transfer records, every email thread, every text message exchange. Then photograph the work. The dodgy tiling, the cracked render, the unfinished roof – document the physical state of things in detail, with dates if your phone records them.

If you’ve already had another tradie look at the work and give you a written opinion on what’s wrong, that’s gold. Include it. The more concrete your file looks, the more seriously it gets taken.

Try to Sort It Directly First

The WA Building Commission will want to see that you made a genuine attempt to resolve things before coming to them. That doesn’t mean you need to chase someone for months who clearly isn’t going to respond: it just means you need to show you tried.

Write a formal letter or email to the contractor. Spell out specifically what the problems are, what you want done about them, and give a clear deadline – two weeks is reasonable in most cases. Keep a copy. If they ignore it, that’s now part of your complaint. If they respond badly, that’s part of it too.

This is also around the point where, if you’re dealing with something complicated or expensive, it’s worth having a quick conversation with WA Property Lawyers who specifically handle building matters. Early advice doesn’t mean you’re escalating; it means you’re not accidentally making moves that damage your own position before the formal process gets going.

Lodge the Actual Complaint

Go to the Building Commission WA website and complete the online complaint form. Don’t rush through it. Be specific about everything. Attach your documentation when you submit. Don’t hold anything back with the plan to send it later. Give them the complete picture from day one, because first impressions within a complaint file do matter.

You’ll get an acknowledgement, then a case officer will be assigned. It takes time, and that’s just the reality of these processes, so don’t expect things to move fast.

What Happens During the Investigation

Your case officer might reach out to both sides for more information. They may arrange an inspection of the building work or attempt a conciliation where both parties try to reach an agreement. Stay responsive during this stage. Getting emotional in written submissions rarely helps anyone’s case.

If conciliation doesn’t resolve it, the matter can be referred for disciplinary action against the practitioner, which can carry real consequences for their licence and registration.

When the Commission Process Isn’t Enough

Some disputes are too large, too contested, or too legally complex to be fully resolved through the Commission alone. If you’re in that situation, property dispute lawyers Perth who actually specialise in building disputes are worth speaking to. They can advise on whether civil action makes sense alongside your Commission complaint, or whether a different route altogether is the stronger play.

Perth property lawyers who work regularly in this space understand where the Commission’s jurisdiction ends and where your other options begin. That kind of clarity is genuinely useful when you’re deep in a dispute and can’t see the exit.

Wrapping Up

The Perth Building Commission exists specifically to protect homeowners from practitioners who don’t do the right thing. Use it. But use it properly, document everything, follow the steps in the right order, and get professional advice early if the stakes are high. That combination gives you the best possible chance of a real outcome.
