How to get a builder’s licence in NSW in 2026: qualifications, experience and the new police check

Getting a builder’s licence in NSW is the step that turns a tradesperson or site supervisor into someone who can contract with a homeowner for a whole job. It is also a step that many experienced people get wrong the first time, usually not because they lack the skills, but because their application does not show the experience the regulator needs to see.

This guide explains when you need a licence, the qualifications and experience required for general building work, the National Police Check that became part of the process on 23 June 2026, and the common reasons applications are refused. It is based on the NSW Government’s published requirements, which were last updated on 3 September 2026. Always check the official page before you apply, because the lists of approved qualifications and units change as training packages are updated.

When you need a licence

In NSW, you need a contractor licence to carry out, advertise or contract for residential building or trade work valued at more than $5,000 in labour and materials, including GST. That requirement also applies to subcontractors: if you subcontract for part of a larger job whose total value is over $5,000, you need a licence in your category even if your own part is smaller. The NSW Government’s example is a $3,000 dry plastering subcontract within a $30,000 kitchen renovation, which needs a dry plastering contractor licence.

Residential building work is broad. It covers constructing, altering or adding to a dwelling, and repairing, renovating, decorating or applying protective treatments to it. The general building work category includes garages, carports and sheds, including kits; kitchen, bathroom and laundry renovations; swimming pool building and structural landscaping; enclosures, atriums and conservatories; house lifting; and cladding removal and replacement.

Doing unlicensed work carries penalties of up to $22,000 for an individual and $110,000 for a company under the Home Building Act. More practically, an unlicensed builder can struggle to recover payment for the work.

Which licence do you need?

There are different licence types depending on whether you want to contract for work, supervise it, do it, or a combination. A company that contracts for building work needs its own contractor licence and a nominated supervisor who holds a qualified supervisor certificate or an endorsed contractor licence. A sole trader who quotes, contracts and supervises their own jobs typically needs an endorsed contractor licence.

Licences and certificates can be issued for one, three or five years. Longer terms mean fewer renewals, and renewal is where CPD comes in: NSW licensed builders must complete continuing professional development to renew. See our guide to NSW builder CPD for how points and renewals work.

The qualifications

For general building work, you must satisfy one of three qualification pathways set out by the NSW Government:

• A vocational qualification. A Certificate IV in Building and Construction, or one of the related Certificate IV qualifications listed, including every required unit of competency, plus one of the additional requirements. Those additional requirements include holding, or being qualified for, a carpentry or bricklaying licence, an approved Diploma of Building and Construction (Building), or an approved university degree.
• A four-year university degree in building, construction, construction management, construction project management, construction economics, applied science (building) or quantity surveying, which includes a mandatory work placement.
• A university degree plus a Certificate IV. An approved degree in a field such as civil or structural engineering, architecture or construction management, combined with the Certificate IV in Building and Construction and its required units.

The required units matter as much as the certificate title. The official list includes units on applying building codes and standards, managing work health and safety, construction contracts, estimating, scheduling and ordering, supervising on-site communication and administration, legal requirements, structural principles, small business finances, reading plans, site surveys and set-out, and resolving business disputes. A Certificate IV missing one of the required units may not qualify. Check your transcript against the current list before you apply.

The experience requirement

Qualifications alone are not enough. You must show at least two years of relevant industry experience in a wide range of building construction work, with the majority of that experience gained within ten years of your application. The rules on what counts are strict:

• The builder you worked for must hold a contractor licence in general building work.
• You must have been supervised and directed by someone holding an individual contractor licence or qualified supervisor certificate in general building work, who confirms your experience on the referee’s statement.
• You must have been paid lawfully for the work.
• Your experience must fall within one of four defined types: an employee of a licensed builder, a licensed subcontractor to a licensed builder, or a qualified supervisor working as a nominated supervisor in the circumstances the Government describes.

The regulator wants to see experience across all stages of construction and a wide range of work, enough to show you can do, coordinate and supervise the construction of a dwelling, deal with subcontractors and consumers, and build in line with the Building Code of Australia. Experience in only one trade, however long, is not enough for a full building licence. Experience as an owner builder does not count. And if you worked on two or more sites at the same time, the overlapping period counts only once.

The National Police Check

From 23 June 2026, all new applications for individual contractor licences, qualified supervisor certificates and tradesperson certificates must include a National Police Check. Building Commission NSW announced the change on 16 June, explaining that it would help identify high-risk individuals before they enter the industry, give access to criminal histories from every Australian jurisdiction, and replace manual checks that could slow applications down.

The check must be issued by an Australian law enforcement agency and be no more than four months old at the date of application. The Commission estimated the cost at about $30 to $80, tax deductible. It said it received around 18,000 individual new applications in the last financial year, and that it is investigating extending the requirement to company licences. The requirement brings home building licences into line with registrations under the Design and Building Practitioners scheme, which already needed a police check.

Why applications fail

The most common problem is not the qualification. It is the experience evidence. The NSW Government states that if an applicant fails to demonstrate the required amount of relevant site-based experience in a wide range of building construction work, the application will be refused. Weak applications tend to share the same faults:

• Thin referee statements that name a builder and a date range but do not describe the work done at each site.
• Trade-only experience, such as years of carpentry without supervision of other trades or the whole build sequence.
• Unlicensed supervision, where the person who supervised the work did not hold the required licence or certificate.
• Old experience, where most of it was gained more than ten years before the application.
• Missing units on the qualification transcript.
• An expired police check, older than four months when the application is lodged.

A worked example: the carpenter moving up

A licensed carpenter has spent eight years framing and fitting out houses for a volume builder, and has completed a Certificate IV in Building and Construction. Their first draft application lists one referee and describes the work as “carpentry and site work”. That application risks refusal: it reads as single-trade experience.

Instead, the carpenter spends a year as a leading hand under the builder’s site supervisor, coordinating other trades from slab to handover, and asks the supervisor, who holds a qualified supervisor certificate in general building work, to document each site in detail: set-out, slab, frame, roof, lock-up, services coordination, wet areas, fit-out, inspections and handover. With two strong referee statements, a transcript that matches the required units, and a fresh police check, the application shows exactly what the regulator is looking for.

After you are licensed

A licence brings obligations as well as opportunities: written contracts for work over the thresholds, home building compensation cover for jobs above the insurance threshold, statutory warranties, and CPD to renew. It also brings the regulator’s attention: the reforms Parliament passed in August strengthen the power to refuse or cancel licences obtained through misrepresentation or invalid qualifications. Getting the application right, with honest and well-documented evidence, is the foundation of everything that follows.

The bottom line

A NSW builder’s licence needs three things: the right qualification with every required unit, at least two years of properly supervised experience across the whole build, and, since June 2026, a current National Police Check. Most refusals come down to experience evidence, so plan it, document it site by site, and have your supervising builders describe what you actually did.
