AI summary

Whether you need building consent for a bathroom renovation depends on the scope of work. Consent is generally required for structural changes, significant drainage alterations, new tiled wet areas, or adding a new bathroom.

Simpler jobs like like-for-like fixture replacements and cosmetic updates are often exempt. However, all work must still comply with the NZ Building Code.

Always confirm requirements with your local council or a licensed professional to avoid fines, insurance issues, and problems when selling your home.
