What building work can I do without a consent in NZ?
Short answer
Schedule 1 of the Building Act lists work that's exempt from building consent — including minor repairs and maintenance, decks under 1.5m, certain small detached buildings, and (under recent changes) standalone single-storey dwellings up to 70m² with conditions. Exempt work must still meet the Building Code, and restricted building work still needs a Licensed Building Practitioner.
Key facts
- Minor repairs and like-for-like maintenance are generally exempt
- Decks under 1.5m above ground are usually exempt
- Small detached buildings and solar installs got easier in 2025
- Standalone single-storey dwellings up to 70m² can be exempt (with conditions and a PIM)
- Exempt work must still comply with the Building Code
Common Schedule 1 exemptions
Work that typically doesn't need a building consent includes:
- General repairs, maintenance and like-for-like replacement
- Decks, platforms and bridges under 1.5m above ground
- Many small detached structures such as sheds (within size limits)
- Cosmetic interior work that doesn't touch structure, plumbing or fire safety
Recent changes (2025–2026)
Schedule 1 was expanded to make it easier to install solar panels and build small detached buildings, and a Schedule 1A exemption now allows standalone single-storey dwellings up to 70m² without a full consent — subject to conditions and obtaining a Project Information Memorandum (PIM). Rules are still evolving, so check the current position with your council.
Exempt still means Code-compliant
Being consent-exempt doesn't mean the rules don't apply. The work must meet the Building Code, and any restricted building work (structural or weathertightness) must still be done or supervised by a Licensed Building Practitioner.
Knowing the rules is half the job. The other half is knowing who you're hiring — check any NZ builder's court action, insolvency history, director track record and AI risk score in 30 seconds.
