8.3. Carports between 20 and 40 sqm in floor area – Licensed Building Practitioner

Simple carport next to house

This exemption relates to roofed structures that are used for motor vehicle storage. To be regarded as a carport, at least one side of the structure must remain open to the outdoors at all times.

Please note: The below exemption comes into force from 31 August 2020. You will still need a building consent if your project starts before this date.

This exemption relates to roofed structures that are used for motor vehicle storage. To be regarded as a carport, at least one side of the structure must remain open to the outdoors at all times. This exemption also includes all work relating to the disposal of storm-water as it relates to the carport.

To qualify for this exemption, a homeowner must engage a Licensed Building Practitioner (LBP) to design, construct and/or supervise any carport with a net floor area (which is taken to be the area within the posts and/or walls supporting the roof structure) not exceeding 40 square metres and the work must be carried out in accordance with that design.

Any design or construction work done using this exemption must be carried out or supervised by a LBP. Homeowners are encouraged to seek LBPs with the right competence for this work, as this provides the best assurance.

The design work is best carried out by a LBP holding a Design licence. The construction work is best carried out by an LBP in one of the following licensing classes, as may be relevant to the building work planned to be undertaken:

  • Bricklaying and blocklaying
  • Carpentry
  • External Plastering
  • Foundations
  • Roofing

Refer to the Who can undertake exempt work section for more information about Licensed Building Practitioners.

You should check and confirm the LBPs current licensing status and licensing history before you engage them to carry out work under this exemption.

If supervision is being applied by a Licensed Building Practitioner under this exemption, that supervision must align with the Practice Note issued for Supervision by LBPs, which can be found at www.lbp.govt.nz.

If the proposed carport is between 20 and 40 square metres, exemption 44 (section 8.2) may apply.
