6.2. Porches and verandas between 20 and 30sqm in floor area – Chartered Professional Engineer

Small house with small porch

This exemption covers porches and verandas between 20 and 30 square metres where the design and construction is carried out by a Licensed Building Practitioner (LBP) and the work is carried out in accordance with that design.

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 allows you to build or extend a deck or veranda up to 30 square metres, provided the design is carried out or reviewed by a Chartered Professional Engineer. The work must also be carried out in accordance with that design.

Before you begin, please read the notes for porches and verandas.

If a homeowner intends to build a veranda or porch less than 20 square metres on the ground floor, exemption 17 (section 6.1.) may be applicable.

What is exempt

  1. A building owner wishes to increase the size of an existing porch from the entry to a dwelling at ground level. The size of the porch (including the existing one) is 25 square metres. Provided that plans and specifications designed or reviewed by a Chartered Professional Engineer and the work is carried out in accordance with that design, the work does not need a consent.
  2. A ground floor apartment owner wishes to increase the area of an existing veranda from 20 square metres to 30 square metres. The design is carried out or reviewed by a Chartered Professional Engineer and subsequently the work is carried out in accordance with that design.
  3. A building owner wishes to increase the area of an existing veranda from 15 square metres to 30 square metres by buying pre-engineered kitset products. The design of this proprietary product has been signed off by a Chartered Professional Engineer and the construction of the veranda will be according to that design.

What needs consent

  1. The owners of a commercial building wish to build a veranda on the first floor level to cover an area of 25 square metres. A building consent is required as the proposed location is above the ground floor of the building.
  2. A shop owner wants to build a 35 square metres veranda in a space without public access. This requires a building consent as the area exceeds 30 square metres.
