Building consent amendments and variations

Changes to consented building work are often proposed during a building project. While the 'approved building consent' (obtained before work commences) is the foundation document for most building work, the building consent process does allow for this consent to be altered before or during construction - through the building consent amendment process.

At the end of the building project, the approved building consent documentation needs to be an accurate reflection of what has actually been built.

Changes to an issued building consent

All changes to the issued building consent documents must be approved and recorded by the Building Consent Authority.

Minor variations

A variation that is minor is a change that does not usually affect compliance with the building code - for example, the type of taps used or positioning of kitchen joinery or non-structural walls or door.  Both Council and owners building consent documentation should be updated to reflect these changes.  Please discuss and record any minor variations on site with your Building Inspector.


Generally, where the work is outside the scope of the original consent (e.g. additional footprint or increases in floor area, construction method, or significant changes to the layout), this would be considered an amendment and requires an application to make the proposed change(s).

An amendment or minor variation must be approved by the Building Consent Authority before the new work is undertaken.

Applying for an amendment

Building work affected by an amendment must not be undertaken until Council has issued the amendment.  Council has 20 working days to process an amendment application.

You can apply for an amendment in the online portal.
