🛡 Compliance & Licensing Guide

You Deserve More Than a Promise.

Our Commitment to Licensed, Compliant Bathroom Renovations Across Australia

Here’s the thing about hiring someone to work on your home — you’re trusting them with something that matters. Your space, your money, and in the case of a bathroom, the structural integrity of your property for years to come.

Every renovator we send to your home is fully licensed, properly insured, and works to Australian building codes and industry standards. Not because we’re ticking a box — because it’s the only way we know how to work.

We’ve seen what happens when homeowners hire unlicensed tradies. Failed waterproofing hiding behind tiles for years. Electrical work that voids a home insurance claim. Bathrooms that fail inspection when it’s time to sell. It’s an expensive mess, and it’s completely avoidable.

Why This Actually Matters (And Why Most People Don’t Find Out Until It’s Too Late)

Bathrooms look straightforward. Tiles, a vanity, maybe a new shower screen. But behind those walls you’ve got plumbing, waterproofing, and electrical running through a small, wet space. Get any one of those wrong and you’re not looking at an inconvenience — you’re looking at structural damage, mould, safety hazards, or a bathroom that fails inspection the day you try to sell.

Non-compliant bathroom work in Australia can mean:

Water damage from failed waterproofing

Inadequate waterproofing lets moisture penetrate substrates. By the time mould or rot becomes visible, the damage is already extensive — and the rectification bill will exceed what the original bathroom cost.

Home insurance claims rejected

Insurers regularly reject water damage claims when non-compliant renovation work is involved. Unlicensed electrical work can void your policy for anything connected to that circuit.

Failed building inspections

Non-compliant plumbing and drainage is flagged at sale or refinance. Buyers' solicitors and building inspectors look for this. An undocumented bathroom renovation is a genuine liability.

Significant rectification costs

Bringing a non-compliant bathroom up to code after the fact — especially once tiling is complete — costs considerably more than getting it right the first time.

Electrical hazards in wet areas

Wiring that wasn't done to AS/NZS 3000 standard in a wet area creates genuine electrocution risk. This is not a theoretical concern — it's one of the most serious risks in a bathroom renovation.

No statutory warranty protection

Hiring an unlicensed contractor voids your statutory warranty rights entirely. There is no legal recourse if the work is defective. The cheap quote stops looking cheap pretty quickly.

Australian renovation work is governed by the National Construction Code and a series of Australian Standards that exist specifically to prevent these problems. They’re not red tape. They’re the reason a properly built bathroom still performs exactly as it should a decade after it was finished.

The Standards Behind Every Renovation We Complete

The National Construction Code sets the minimum performance requirements for all residential building work in Australia. It’s the foundation everything else sits on — and our projects are built to meet it, not work around it. For a bathroom renovation specifically, the key standards that shape how we work are:

🏗️
NCC Volume 2
National Construction Code

Sets the baseline performance requirements for all Class 1 residential buildings. The foundation everything else sits on.

💧
AS 3740
Waterproofing of Wet Areas

Defines exactly where membranes go, how high they run up walls, and how they must be sealed. Non-compliance is the single most common cause of bathroom defect claims.

🔧
AS/NZS 3500
Plumbing & Drainage

Governs all plumbing work — water supply, sanitary drainage, hot water, and fixture connections. Must be completed by a licensed plumber in every state.

AS/NZS 3000
Australian Wiring Rules

Covers all electrical installation in bathrooms, including mandatory RCDs on all bathroom circuits. Wet areas and electricity require a licensed electrician — no exceptions.

These standards aren’t just hurdles to clear. They’re the reason a bathroom built properly still performs exactly as it should five, ten, even fifteen years down the track. We treat compliance as a quality benchmark, not a minimum we’re aiming for.

Licensed Contractors in Every State — Not Just a Claim, We’ll Show You the Numbers

In Australia, building and trade licensing is handled state by state. The licence your contractor needs in Queensland is different from the one they need in Victoria — and every state has its own authority that issues and monitors them. We work with licensed and registered contractors in every state and territory we service.

New South Wales
NSW Fair Trading

Contractor Licence — Residential Building Work

Victoria
Victorian Building Authority (VBA)

State requirements can change. The above is a general guide only. Your Lifestyle Bathrooms specialist will confirm the exact permit and licensing requirements for your specific property location and scope of work before your project begins.

Before any renovation starts, you have every right to ask for your contractor’s licence number and verify it yourself. Go to your state authority’s website, type in the number, and check it’s current and valid for the work being done. We’ll give you our details before you even ask — because if a contractor hesitates when you raise that question, that’s already a red flag.

Ask for our licence details any time — before you sign, before we start, at any point. We’ll send them without hesitation.

Waterproofing: The Part That Really Can’t Be Skipped

If you only remember one thing from this page, make it this: bad waterproofing is the single most expensive mistake in a bathroom renovation — and you won’t know it happened until the damage is already done.

AS 3740 is the Australian Standard that governs how waterproofing must be applied in domestic wet areas. It sets out exactly where the membrane goes, how high it runs up the walls, and how it must be sealed at corners and junctions.

Under AS 3740, waterproofing in a bathroom must:

  • Cover the full floor area of all wet zones and extend up walls to the minimum required heights
  • Run to at least 1,800mm from the shower rose inside a shower recess
  • Be inspected and certified before tiling starts — once tiles go on, there’s no way to verify what’s beneath them
  • Be completed with documented sign-off on the job file

The damage from non-compliant waterproofing typically shows up years after the renovation — by which point the rectification cost well exceeds what the original bathroom cost to build. Water finds its way through any gap, and once it’s in your wall cavity or subfloor, you’ve got a serious problem on your hands.

On every project, waterproofing is independently inspected before a single tile goes down. That sign-off stays on file. No shortcuts, no exceptions, no matter the project size or budget.

Certified waterproofing is non-negotiable on our jobs. Tiling doesn’t start until that inspection is signed off.

Electrical and Plumbing — Licensed Tradespeople Only, Every Single Time

There’s no grey area here. Water and electricity sharing the same small space means every piece of electrical and plumbing work has to be done correctly, by someone who’s licensed and qualified to do it. We don’t cut costs by using unlicensed labour — on any job, at any price point.

Electrical

  • All electrical installation to AS/NZS 3000 (Australian Wiring Rules)
  • Safety switches (RCDs) required on all bathroom circuits — no exceptions
  • Only licensed electricians touch the wiring
  • Certificate of Compliance for Electrical Work issued on completion and handed to you

Plumbing

  • All plumbing to AS/NZS 3500 — water supply, drainage, hot water, and fixture connections
  • Completed by licensed plumbers only
  • Compliance certificates issued where required by state law
  • All certificates provided to you at project completion

Those certificates matter beyond the renovation itself. When you sell the property, refinance, or make an insurance claim, a bathroom with proper compliance documentation is worth considerably more than one without. Buyers’ solicitors check these things. Insurance assessors check these things. Make sure yours are in order.

Fully Insured — Because Things Don’t Always Go to Plan

Most renovation jobs go smoothly. But ‘most’ isn’t ‘all’, and when something unexpected happens on your property, you need to know everyone involved is properly covered.

🛡️
Public Liability Insurance

If something gets damaged or someone is injured during the renovation, you're covered. We carry this on every job.

👷
Workers Compensation

Every person on your site is covered while they're working. You bear no liability for on-site injuries.

🏡
Home Warranty Insurance

Mandatory in NSW, VIC, and QLD above the relevant threshold. Protects your deposit if the contractor can't complete the job.

Home Warranty Insurance is worth understanding. It protects you if a licensed contractor can’t complete the job — due to insolvency, death, or disappearance. It covers your deposit and any incomplete work. Several states require it by law, for good reason.

Ask any contractor you’re comparing quotes from for proof of insurance before you commit. Any contractor worth hiring will produce it immediately. We share ours upfront.

Safe Sites, Straight Talking, No Nasty Surprises

We work in compliance with Work Health and Safety (WHS) legislation across all Australian states and territories. In practice, that means a few things you’ll notice — and a few that just happen quietly in the background.

What you’ll actually see on your job:

  • The site is left clean and safe at the end of every working day — we’re in your home, and we act accordingly
  • Asbestos awareness protocols followed on every project — particularly important in homes built before 1990, where asbestos-containing materials can appear in wall sheeting, floor tiles, and adhesive compounds
  • If something unexpected turns up behind the walls — old waterproofing failures, previous work done wrong, anything we didn’t anticipate — we stop and talk to you before touching it
  • Safe work practices maintained throughout to protect our team and anyone in your household

A professional tradie runs a professional, safe site. That’s not a compliance exercise — it’s just how the job should be done.

Our Warranty — And Why It Only Exists If Your Renovator Is Licensed

When licensed contractors carry out residential building work in Australia, you’re automatically entitled to statutory warranty protections under home building legislation. These aren’t something we offer on top — they’re your legal rights as a homeowner.

6
Years — Structural Defects

Statutory warranty from completion date for all structural defects under Australian home building legislation.

2
Years — Non-Structural Defects

Covers fixtures, fittings, waterproofing quality, and finish defects that appear after completion.

We stand behind our work beyond those minimums. A bathroom that needs fixing two years after we finished it isn’t just a warranty issue to us — it’s a workmanship problem, and we’d want to know about it and sort it out.

Here’s the part that catches people off guard: these protections only apply if the work was done by a licensed contractor. Hire someone unlicensed — no matter how cheap the quote or how nice the tiles look — and you have no legal recourse if things go wrong. None. The statutory warranty simply doesn’t apply.

That’s not a scare tactic. It’s just how the legislation works.

We stand behind our work. If something isn’t right after we’ve finished, we want to know about it — and we’ll fix it.

How We Actually Make Sure Everything Is Done Properly

Saying you’re compliant is easy. Here’s how we make it happen, from the first site assessment through to the day we hand over your keys.

1
Before We Start — Scope and Compliance Review

Your project is assessed against the NCC and all relevant Australian Standards before anything is scoped or quoted. If there's a compliance requirement specific to your renovation — a plumbing relocation that triggers additional permit requirements, for example — you'll know before you sign anything.

Before Works Begin
2
The Right People for the Right Work

Licensed plumbers, electricians, waterproofers, and builders are matched to each project based on scope and location. Everyone on your job holds the correct licence for their work in your state. No one does work outside their registration.

Project Mobilisation
3
Waterproofing Inspection Before Tiling Starts

AS 3740-compliant waterproofing is applied and independently inspected before a tile is laid. This is a hard stop in our process. Tiling doesn't proceed until sign-off is on file.

Before Tiling
4
Certificates Handed Over on Completion

All compliance certificates — electrical, plumbing, and waterproofing — are collected and given to you when the job is finished. Keep them with your property records. You'll want them when you sell or refinance.

Final Walk-Through Before We Leave

Before we pack up, your bathroom is reviewed against scope, finish quality, and compliance requirements. If anything isn't right, we fix it before we go — not after a follow-up call, not next week. Before we leave.

Handover

That’s the process. No surprises, no chasing us up, no ‘we’ll pop back and sort that out.’

Do You Need a Building Permit for a Bathroom Renovation?

The straightforward answer: it depends on the scope of work and the state your property is in. Here’s a practical reference guide — but always confirm with your renovator or local council, as requirements vary.

Questions We Get Asked a Lot

Every state has a free online licence check. In NSW, go to NSW Fair Trading. In QLD, use the QBCC website. In VIC, search the Victorian Building Authority register. Enter the licence number and you’ll see whether it’s current, what it covers, and whether there are any complaints on file. Do this before you sign anything.
AS 3740 is the Australian Standard for waterproofing domestic wet areas. In plain language, it defines exactly how waterproofing must be applied in your shower, around your bath, and across wet floor areas. Non-compliant waterproofing is behind a large proportion of the water damage and mould problems homeowners deal with years after a renovation. The frustrating part is that everything looks fine on the surface — until it doesn’t.
Usually no. A standard bathroom renovation generally doesn’t require a Development Approval or council permit. But if you’re moving walls, relocating drainage, or making structural changes, a building permit may be required. We confirm this during the pre-project review and give you a straight answer before anything starts.
A few things, none of them good. Your statutory warranty rights don’t apply — there’s no legal protection if the work is defective. Your home insurance may reject any claim tied to that work. And if the renovation isn’t up to code, the rectification cost comes out of your pocket. The cheap quote stops looking cheap pretty quickly.
Yes — all building codes and compliance requirements apply equally to investment properties. For landlords, non-compliant bathrooms can create significant tenant safety liabilities and affect landlord insurance coverage. Property investors should treat compliance as non-negotiable.
When you purchase a property, you may inherit liability for any non-compliant renovation work. A thorough pre-purchase building inspection should identify this. If you’ve already purchased and discovered the issue, consult a licensed building consultant to assess what’s required to bring the work up to code.
Some cosmetic work can be done by homeowners. However, plumbing, electrical, gas, and waterproofing must be completed by licensed tradespeople in all states. Owner-builder permits exist but come with strict conditions, financial limits, and insurance implications. For most bathroom renovations, professional management is considerably more straightforward.
Permit processing typically ranges from 5 to 25 business days, depending on your state and local council. We lodge permit applications as early as possible and build the processing time into your project schedule so it doesn’t delay your start date.
