If you’re planning any construction, demolition or alteration work, you probably need to obtain a building consent before the work begins. Some work may also require resource and earthworks consents, and vehicle access approval.
A building consent verifies that the work proposed complies with the building code.
Work cannot start until you have a building consent and all other necessary authorisations (such as resource consents, earthworks bylaw consents).
You need to allow at least four weeks to obtain a building consent when planning your project.
Once a consent has been issued, work must begin within 12 months and adhere to approved building plans. Inspections are required throughout the construction process in order to secure the final Code Compliance Certificate.
You should plan to complete your project within two years.
The following are examples of work requiring a building consent:
Schedule 1 of the Building Act lists work that does not need a building consent.
Work on new or existing kerb crossings and driveways. You will need to provide a range of information including gradients, crossfalls, widths and surfacing.
If you are constructing a vehicle crossing (driveway) or amending an existing one to access the legal road from your building/house site, you will need a permit from the Access and Transport team. This is a separate process and not part of your building consent.
More information and the application form is available on our Access and Transport Vehicle Crossings page.

If your are altering the ground level or moving earth, you may need a resource consent for earthworks. Earthworks are not covered by your building consent.
Council requires all new homes to install a greywater system and/or a rainwater storage tank. Rainwater would be used for toilet flushing and outdoor water uses while greywater from the washing machine and bathroom would be used for outdoor irrigation.

Council has developed performance standards for two acceptable water management solutions:
