What can I do WITHOUT a Building Consent?

All building work must comply with the building code, however some work doesn’t need a Building Consent. Read on to see what can you do WITHOUT a Building Consent ….

If you are a building or home owner that is planning work and intend to carry it out yourself, then we have some guidance on what you can do without a building consent! Trade and sector professionals may be commissioned to do the work and provide advice on your project. All building work, whether it needs a building consent or is exempt, must still comply with the Building Code and other relevant legislation. For example work on plumbing, gas fitting, drain laying, electrical etc will still need to be to code and get relevant sign off from professionals. We are here to help, see below for a couple examples of types of work you don’t need a consent for…


Without a consent you can do various works including general repair, maintenance and replacement. You can build single-storey detached buildings not exceeding 10 square meters, depending on its material you can also build something slightly bigger (10-30sqm). Demolition of a detached building up to 3 stories high is also permitted without consent. Various exterior/landscaping works including building porches, veranda's, some pools, platforms, bridges and boardwalks are also permitted to a certain size and scope.
