WA builder registration: Building Services Board classes, fees and obligations

TL;DR

WA residential building work valued over $20,000 that requires a building permit must be carried out by a registered building contractor under the Building Services (Registration) Act 2011 (WA). Registration is issued by the Building Services Board, administered by Building and Energy (under the Department of Local Government, Industry Regulation and Safety). There are two registration tiers: a building practitioner (individual supervisor, cannot contract directly) and a building contractor (the entity that signs and delivers the contract). Registration runs for three years; renewal fees are $538 for an individual contractor and $803 for a practitioner (verified 2026-05-08). Home indemnity insurance is compulsory for residential work over $20,000 before accepting any payment. Unregistered building work attracts a fine of $25,000. Owner-builder approval is available but the property cannot be sold within seven years of the building permit without home indemnity insurance.

In plain English

The Building Services Board (BSB) registers building contractors and practitioners in WA. Administrative support comes from Building and Energy (DEMIRS). The scheme runs under the Building Services (Registration) Act 2011 (WA).

WA uses “registration” not “licence.” The framework separates the individual supervisor (building practitioner) from the entity that contracts with clients (building contractor). A sole trader can hold both simultaneously; a company or partnership must nominate at least one registered practitioner.

What it requires

The two-tier structure

Registration type	Who applies	What it permits
Building practitioner	Individuals only	Supervise and manage building work as a nominated supervisor for a registered contractor; use the title “registered building practitioner”
Building contractor	Individual, partnership or company	Contract directly with clients for building work valued over $20,000 that requires a building permit; must have at least one nominated practitioner

A building practitioner may not provide building services directly to a client. All client-facing work must flow through a registered contractor entity.

What counts as building work

Building work under this scheme covers construction, erection, assembly, placement, renovation, alteration, extension, improvement, repair and demolition of buildings, and associated site preparation. The trigger: the work requires a building permit and the estimated value exceeds $20,000 (verified 2026-05-08, WA Government: Builders’ registration).

Excluded from the registration requirement: farm buildings, prefabricated structure manufacturing, parking areas, sporting surfaces, fire sprinklers, partition installation, safety systems, timber decking, glazing installation, cabinet making, freestanding fences and pools.

Qualification pathways (practitioner)

Building practitioner registration is the prerequisite for a contractor. Five sets apply (verified 2026-05-08, WA Government: Building practitioner registration):

Set	Qualification	Experience required
1	CPC50220 Diploma of Building and Construction	7 years full-time building work
2	Architect, surveyor or engineer registration; or RAIA / Engineers Australia / AIMM membership	5 years supervising construction
3	Australian Institute of Building membership	5 years in building construction
4	Board exam or RTO assessment (RPL available)	5 years supervising or managing construction
5	Board exam or RTO assessment (RPL available)	7 years WA building work outside Board jurisdiction

Financial requirements (contractor)

Must demonstrate: at least $50,000 cash or equivalent, quick ratio of at least 1:1, and capacity to meet debts as they fall due (verified 2026-05-08, WA Government: Building contractor registration).

Registration fees

Registration runs for three years. Fees are set under the Building Services (Registration) Regulations 2011 and reviewed periodically. Current fees (verified 2026-05-08, Building and Energy fees):

Registration type	New application (registration + application fee)	Renewal fee
Building practitioner	$1,080 ($803 registration + $277 application)	$803
Building contractor, individual	$815 ($538 registration + $277 application)	$538
Building contractor, partnership	$2,197 ($1,740 registration + $457 application)	$1,740
Building contractor, company	$4,157 ($3,700 registration + $457 application)	$3,700
Late renewal surcharge		$65

All fees are ex-GST. If an application is rejected, the registration fee component is refunded; the application fee is non-refundable.

CPD requirements

The Act and current regulations do not mandate CPD as a condition of renewal (verified 2026-05-08). No CPD obligation; renewal is fee-based only.

Registration term and renewal

Three years. Lodge renewal before expiry to avoid the $65 late surcharge. Processing: within 50 business days for complete applications (verified 2026-05-08, WA Government: Building contractor registration).

Home indemnity insurance and contract rules

Residential building work over $20,000 requires home indemnity insurance (HII) in the owner’s name before accepting any payment or commencing work (verified 2026-05-08, Building and Energy: HII obligations). Key rules:

Policy in the owner’s name; certificate submitted with the building permit application
Coverage from commencement to six years after practical completion
Exempt: associated-works-only contracts (pool installation, kitchen cabinetry, landscaping)
Under the Home Building Contracts Act 1991 (WA): deposit capped at 6.5% of contract price; all variations in writing, dated and signed before work starts (verified 2026-05-08, WA Government: Obligations for registered providers)
Builders building for themselves: HII required if they intend to sell within seven years of the building permit date

Owner-builder approval

Lets an individual property owner be named as the builder on a permit (work over $20,000) without contractor registration (verified 2026-05-08, WA Government: Owner-builder approval). Requires either a current/previous building registration or completing a WA owner-builder training course within 24 months of application.

Restriction	Detail
Selling restriction	Selling within 7 years without HII: $10,000 fine
Re-application limit	No second approval within 6 years of a prior permit (hardship waivers available)
Specialist trades	Electrical, plumbing and gas must still be licensed contractors
Administration	LGIRS Licensing Services: 1300 489 099

Penalties

Offence	Penalty
Carrying out building work without registration (s 7(1), Building Services (Registration) Act 2011 (WA))	$25,000 fine
Contravening a registration condition (s 40)	$25,000 fine
Selling owner-built dwelling within 7 years without HII	$10,000 fine
Breach of deposit cap or contract rules (Home Building Contracts Act 1991)	Up to $10,000 (individual) or $50,000 (company)

All verified 2026-05-08. Disputes go to the Building Commissioner (jurisdictional limit $100,000) under the Building Services (Complaint Resolution and Administration) Act 2011 (WA), with escalation to the State Administrative Tribunal (SAT).

Practical implications

For the builder:

Keep a registered practitioner nominated at all times. If your nominated practitioner leaves, replace them before the contractor registration lapses.
Obtain HII before the first payment, not before work commences. No HII certificate = no building permit.
Deposit cap is 6.5% of the contract price. Anything higher is a Home Building Contracts Act offence.

For the homeowner:

Verify registration free at MyLicence WA (BC prefix for contractors, BP for practitioners) before signing.
No HII certificate = do not pay the deposit. The certificate must be in your name.
Statutory warranties run for six years from practical completion.

For owner-builders:

Approval required before the building permit is issued for work over $20,000. Course required unless you hold a building or design registration.
If you intend to sell within seven years, obtain HII or face a $10,000 penalty.
