Every rule and rate below for Western Australia is read from Sumitt's own tables when this page renders, not written for it.
The rules in Western Australia that Sumitt already knows
Every rule below is read, when this page renders, from Sumitt’s own law tables: the ones the quote builder, the variation composer, the extension-of-time notice and the payment-claim generator run on, and its table of the Security of Payment Acts of the states it builds no claim for. Sumitt warns and never blocks, and the page moves the day a table does.
Deposit cap in Western Australia
The law in Western Australia caps a deposit at 6.5% of a home building work contract over $7,500 and under $500,000 (Home Building Contracts Act 1991, s 10, and Home Building Contracts Regulations 1992, r 2A).
Up to 20% can apply to a contract for cabinetry work, other than off-the-shelf cabinets, where more than half the contract value is work done off-site (Home Building Contracts Regulations 1992, r 3A).
Check it applies to your contract.
Western Australia's deposit cap applies only to a home building work contract over $7,500 and under $500,000. For a job of $7,500 or less, or $500,000 or more, a deposit of about 10% is common practice, not law.
Sumitt's default deposit is 10% of the total including GST. Sumitt warns you when a deposit goes over the line, and it never changes the deposit you set.

Licence line in Western Australia
Sumitt's licence-line warning covers New South Wales, Victoria and Queensland today. It carries no line for Western Australia, so the licensing rules there stay yours to check.
Security of Payment claims in Western Australia
Western Australia's Building and Construction Industry (Security of Payment) Act 2021 lets you give a payment claim for a progress payment (s 22). It does not apply to a contract for home building work with an individual, worth $500,000 or less, unless the work is for multiple dwellings or their residential development business; a contract between a head contractor and a subcontractor, or between two subcontractors, stays covered (s 10(1)).
Sumitt builds the payment claim for New South Wales, Victoria and Queensland today, not yet for Western Australia, so in the app an overdue invoice there runs up the follow-up ladder to the letter of demand.

Variations in Western Australia
In Western Australia the variation rules, ss 7 and 8 of the Home Building Contracts Act, bind a home building work contract between a builder and an owner over $7,500 and under $500,000, not a cost plus contract or a subcontract (s 3(1), and the Home Building Contracts Regulations 1992, r 2A).
A variation must be in writing, set out all of its terms and its cost, show its date, and be signed by the builder and the owner or their agents (s 7(1)).
Give the owner a copy of the signed variation as soon as reasonably practicable after both of you sign it, and before its work starts (s 7(2)). Section 8 takes out of s 7(1) and (2) a variation made necessary by a written direction lawfully given by a person acting under a written law, or by circumstances you could not reasonably have foreseen when the contract was entered into, but only if, within 10 working days after you received notice of the direction or became aware, or should reasonably have become aware, of the circumstances, you give the owner a statement setting out the reason for the variation and its cost, and a copy of any such direction (s 8(1) and (2)). A rise in your labour or materials costs alone does not bring a variation within the second of those (s 8(4)).
Section 7(3) makes these the builder's duties, and a failure does not by itself make the contract, or a provision of it, illegal, void or unenforceable (s 27(1)). Without the variation signed by you both, the price of the extra work is your word against the owner's.
On a contract the Act covers, the owner's copy of the signed variation before the varied work starts is a statutory element (s 7(2), which has effect subject to s 8, s 13(4) and Sch 1 cl 5, as s 7(4) says), not just good practice. Sumitt flags a running job that has an unapproved variation on it.
Sumitt structures the variation, records your signature as you send it and collects the owner's at the link, a record you keep, not legal advice. Where your contract sets its own variation process, follow it too.

Extensions of time in Western Australia
In Western Australia the contract sets the extension-of-time window. Sumitt's notice defaults to 10 calendar days from the day the delay ended, shows the countdown, and asks you to check the contract's own figure.
A template you serve in your own name, not legal advice. Your contract's own extension-of-time clause governs the window and the grounds, so check it and keep a copy of everything.

What the work costs in Perth / WA metro
Sumitt's Perth / WA metro card runs materials at 1.03 and labour at 1.02 against the national card at 1.00. Outside the metro the Regional (freight + travel) card applies: materials 1.08, labour 1.03.
| Job | Cost | Floor | Healthy | Premium | Healthy, Perth / WA metro | |

National figures per unit, ex GST, derived from Sumitt’s 2026 rate cards priced over the benchmark scope shown under each job; the last column prices the same scope on the Perth / WA metro card. Cost is the benchmark cost of doing the work before any margin, and Floor, Healthy and Premium are the sell rates that land those margins. Not a survey of what anyone else charges, and nothing here reflects what any Sumitt user charges. How to read it, and the method, are on the index.
