Key points at a glance
- The Building Code sets the performance all building work must achieve, not how to achieve it.
- It is contained in Schedule 1 of the Building Regulations 1992.
- Compliance can be shown via Acceptable Solutions, Verification Methods, or an alternative solution.
- All building work must comply with the Code — even work that does not need a consent.
How the Code is structured
The Building Code is performance-based: it states the outcomes building work must achieve rather than prescribing exact methods. It is organised into clauses covering areas such as stability (B), protection from fire (C), access (D), moisture and weathertightness (E), safety of users (F), services and facilities (G), and energy efficiency (H).
Because it is performance-based, there is often more than one way to comply, giving designers and builders flexibility while keeping a consistent safety and durability standard.
Ways to show compliance
MBIE publishes Acceptable Solutions and Verification Methods — recipes that are automatically accepted as meeting the Code. Following one of these is the simplest route to compliance.
You can also use an alternative solution, where you demonstrate through evidence, testing or expert opinion that a different approach still meets the Code. Product certification schemes such as CodeMark can support this.
For homeowners
- Ask your designer or builder which Acceptable Solution or method your project follows.
- Weathertightness (clause E2) is critical — make sure cladding details are Code-compliant.
- Code compliance underpins your Code Compliance Certificate and future resale.
For tradespeople
- Cite the relevant Acceptable Solution or Verification Method in your documentation.
- Keep product data and CodeMark certificates for alternative solutions.
- Remember the Code applies to exempt work too, not just consented work.
