09 consent # Auckland building consent guide ## Summary General guide, with sources: **deck** (often no consent if fall is under 1.5 m), **kitchen and bathroom** (like-for-like usually none; tiled shower or added fixture needs consent), **roof** (comparable replacement in same position exempt), **carport** (ground-level up to 20 m2 exempt). Overlays can still need resource consent. Confirm with Auckland Council. General information summarised from the sources below on 2 Nov 2026. Rules change and every property is different. Confirm with Auckland Council before starting. Not legal advice. ## Deck A deck with no fall over 1.5 m often needs no building consent, but resource consent may still apply (such as site coverage or overlays). A handrail or barrier is needed over 1 m. Source: Auckland Council, build a deck. ## Kitchen and bathroom Like-for-like fixture changes are unlikely to need building consent. A tiled wet-area shower or an added fixture normally does. Plumbing must be done by an authorised person. Source: Auckland Council. ## Roof A comparable replacement in the same position is exempt from building consent (Schedule 1, exemption 1). A complete or substantial replacement with a different material, or work due to a durability failure, is not. Source: Building Performance (MBIE). ## Carport A ground-level carport up to 20 m2 is exempt, and 20 to 40 m2 can be exempt with licensed building practitioner supervision. Source: Building (Exempt Building Work) Order 2020. ## Overlays and sites Special character, flood, overland-flow, heritage and protected-tree overlays can add resource consent requirements even when building consent is not needed. Check your property on Auckland Council GeoMaps. ## Licensed building practitioners Restricted building work, such as structure and weathertightness on a house, must be done or supervised by a licensed building practitioner. Check the LBP register. ## Before work starts * [MBIE Building Performance: before building work starts (your rights)](https://www.building.govt.nz/getting-started/your-rights-and-obligations/homeowner-rights-and-obligations/know-your-rights-consumers/before-building-work-starts) * [MBIE Building Performance: consumer protection, disclosure statement and checklist](https://www.building.govt.nz/projects-and-consents/why-contracts-are-valuable/consumer-protection-disclosure-and-checklist) * [MBIE Building Performance: get the right people for your project](https://www.building.govt.nz/projects-and-consents/planning-a-successful-build/scope-and-design/choosing-the-right-people-for-your-type-of-building-work) ## Sources * [Auckland Council: build a deck](https://www.aucklandcouncil.govt.nz/en/building-and-consents/building-renovation-projects/build-deck.html) * [Auckland Council: kitchen and bathroom renovations](https://www.aucklandcouncil.govt.nz/en/building-and-consents/building-renovation-projects/kitchen-bathroom-home-renovations.html) * [Building Performance (MBIE): general repair, maintenance and replacement (Schedule 1, exemption 1)](https://www.building.govt.nz/projects-and-consents/planning-a-successful-build/scope-and-design/check-if-you-need-consents/building-work-that-doesnt-need-a-building-consent/technical-requirements-for-exempt-building-work/1-general-alterations-maintenance-and-removal/1-1-general-repair-maintenance-and-replacement) * [Building (Exempt Building Work) Order 2020](https://www.legislation.govt.nz/regulation/public/2020/0171/9.0/whole.html) * [Building Practitioners (LBP) register search](https://kete-lbp.mbie.govt.nz/advanced-building-practitioner-search/) * [Companies Office: business entity data](https://www.companiesoffice.govt.nz/data-services/available-data/business-entity-data/) * [New Zealand Business Number register](https://www.nzbn.govt.nz/) * [Auckland Council GeoMaps](https://geomaps.aucklandcouncil.govt.nz/) * [Google Maps Platform policies](https://developers.google.com/maps/documentation/places/web-service/policies)
