Change of use, Extension of life, and subdivision

Sections 113-116B Building Act 2004, and sections 5-6, schedule 2, Building (Specified Systems, Change the Use, and Earthquake-prone Buildings) Regulations 2005

Overview

Change of Use
All buildings have designations that specify their use and their requirements under the Building Code. This can be in relation to all or just part of a building.

In order to change the designation of a building, there are various requirements that must be met, these include:
  • written confirmation from the building owner to the Territorial Authority (section 114).,
  • that the TA is satisfied that building in its new use will comply with the Building Code “as near as reasonably practicable”,
  • that the building complies with requirements around access and escape for fire,


It is also possible that a building consent might be required.

In general, it is important that the building is no worse off than before. For example, if a build had sufficient glazing, insulation, and access to natural light, these aspects ought not be compromised as a result of the change of use.

Extension of Life
There are rules around extending the life of a building with a specified length of life. 

Specifically, this affects buildings which were granted consent under section 113, which are buildings intended to be used for a particular purpose for 50 years or less.

The law provides that an owner wanting to extend the life of such a building must give notice to the territorial authority and receive written consent.

Subdivisions
If subdividing, the buildings involved must continue to comply, “as nearly as is reasonably practicable”, with the Building Code, especially in relation to:
  • means of escape from fire,
  • access and facilities for persons with disabilities (if this is a requirement under section 118),
  • protection of other property,


Otherwise, there will be a need to upgrade these or other parts of the building in order to achieve compliance.
