We checked Building Commission NSW, NSW Government and Service NSW pages on 1 November 2026. We found no recent change to the owner builder permit rules themselves, but several wider 2026 changes affect residential building, and the core owner builder rules still apply. This guide sets out what changed, when, and what you should do, and flags what we could not confirm.
The owner builder rules that apply now
These are existing rules rather than new ones. None of the pages below shows a “last updated” date (they show only a 2026 copyright line), so check them before you act.
- Permit: you need an owner builder permit for work valued at over $10,000 on your own home if you are not contracting a licensed builder to supervise it, as this page explains. Only one permit can be issued in any five-year period unless the application and an earlier permit relate to the same land or special circumstances apply.
- Applying: the application page lists the documents you need, including a current white card and an approved DA or CDC. It says assessment takes up to three business days. See our step-by-step permit guide.
- Education: work valued at more than $20,000 needs the owner builder education requirement or an approved equivalent. The NSW Government wording varies slightly, with one page saying “more than $20,000” and another “$20,000 or more”, so confirm on the live page. Our NSW owner builder course is one way to meet it.
- Fee: $233 for a new one-year permit, per the fees page (July 2026 to June 2027, last updated 1 September 2026).
- Responsibilities: the working as an owner-builder page says trades over $5,000 must be licensed, electrical, plumbing, draining, gasfitting and air-conditioning work always needs a licensed person, and you must meet work health and safety duties. Knowingly hiring an unlicensed contractor carries a maximum penalty of $22,000.
- Selling: if you sell within 7 years and 6 months of the permit being issued, the contract must include a consumer warning (same page).
What changed in 2026
Police checks for new trade licence applicants (23 June 2026)
Building Commission NSW announced on 16 June 2026 that, from 23 June 2026, new applications for Individual Contractor Licences, Qualified Supervisor Certificates and Tradesperson Certificates need a National Police Certificate no more than four months old. The page does not mention owner builders. It affects the trades you hire, not your permit. Our suggestion, not an official requirement, is to keep checking every contractor’s licence before you sign.
Critical stage inspections (22 May 2026)
The industry changes page (last updated 19 August 2026) says changes introduced on 22 May 2026 let building surveyors registered in certain restricted classes carry out critical stage inspections one registration class above their own, under supervision. This is a certifier matter, with no new task for owner builders.
The Building (Approvals and Practitioners) Act 2026 (passed August 2026)
The NSW Government’s Building Productivity Reforms page (last updated 19 August 2026) says this Act passed Parliament in August 2026. It covers prefabricated and modular buildings, modernising building approvals, and dispute resolution for occupied apartment buildings, and strengthens rules on certifier conflicts of interest. The page says the reforms take effect once the associated regulations are developed, with industry consultation during 2026 and 2027. No start date is given and the page does not mention owner builders. For now, nothing changes for your permit or approvals, but watch for the regulations.
A ministerial release dated 5 August 2026 says certifier fines for breaching conflict of interest rules rise from $33,000 to $1.1 million. The Building Commission page words this as “proposed to increase”, so we have not treated the new penalty as in force.
Design and Building Practitioner changes (deferred)
The industry changes page says regulation changes due to start on 1 July 2026 have been deferred. They relate to extending the Design and Building Practitioners Act 2020 to class 3 and 9c remedial work and to practitioner professional indemnity insurance. They are not aimed at typical owner builder homes.
National Construction Code update (1 May 2027)
The same page says NSW will adopt NCC 2025 on 1 May 2027. The current edition is NCC 2022 Amendment 2, in effect since 29 July 2025. If your build will run past that date, ask your designer or certifier which edition applies to your approval.
What owner builders should do now
- Confirm your permit, education and white card requirements on the live pages above.
- Check every trade’s licence, and use only licensed people for specialist work.
- Keep your insurance certificates and written contracts.
- Ask your certifier whether the NCC change affects your timing.
- Recheck the Building Commission NSW industry changes page every few months.
What we could not confirm
- Any 2025 or 2026 change to owner builder permit thresholds, the application process or the education requirement. We found none on the pages we read.
- The date and legal basis of the move of owner builder regulation to Building Commission NSW. The pages now say Building Commission NSW manages permits, with Service NSW taking applications, but we found no transfer date.
- Any start date for the Building (Approvals and Practitioners) Act 2026.
- Whether the higher certifier penalty is already in force.
