If you wish to make changes to your building consent this may be done by way of a minor variation or an amendment. An approved variation or amendment must be obtained before the work is carried out.

Minor changes (variation)

If the change is not significantly different from the approved building consent plans and specifications, you can request approval for a minor variation. These are usually able to be carried out on-site by your building inspector. Some examples of minor variation include:

  • substituting similar products (e.g. one internal lining for a similar internal lining minor wall bracing changes)
  • minor construction change (e.g. changing the framing method used around a window)
  • changing a room's layout (e.g. repositioning fixtures in a bathroom).

Building inspectors may approve minor variations that arise in the course of building work. These are changes that do not affect compliance with the building code. Minor variations are recorded on an inspection site notice.

If you are requesting a minor variation this must be done before the work is undertaken and you will need to provide:

  • two sets of amended drawings
  • authorised owners approval.

You can find more information about minor variations(external link) at the Ministry of Building, Innovation and Employment (MBIE) website.

Major changes (amendment)

If the change is significantly different to your approved plans, these must be formally authorised as amendments to the building consent. To request an amendment, submit an Application for a Building Consent [PDF, 776 KB] (Form B-002) also available in Word [DOCX, 423 KB]

Some examples of amendments include, but are not limited to:

  • any alteration that increases or decreases the floor area of the building
  • relocating or removing internal load-bearing supports
  • substantive changes to ground level, resulting in changes to foundations or retaining structures
  • changes to fire safety aspects.

We recommend that you submit your amendment application online, to avoid delays and scanning fees. Alternatively, you can also submit your application at the Civic Building(external link), 53 Hereford St, Christchurch.

An application for amendment is processed in the same way as an original consent application. The Council is required to process the amendment application within 20 working days, and charges for processing at the same hourly rates. Unless the changes are extensive, however, amended consents can usually be processed quickly.

Get your amendment application approved prior to undertaking the building work.

Fees for amendments

A lodgement fee is charged for an application for amendment of a building consent. Refer to the Building Consents Fee Schedule. You may also incur charges based on the additional time required to review and process the amended consent, or for additional inspections.
