Description

If you want to substitute a building product originally specified in your building consent application, you need to show the council how it meets the Building Code requirements.

When deciding how to deal with a product substitution, the responsibility falls on the applicant to demonstrate that the proposed substitute will meet the performance requirements of the Building Code. Where the new product performs differently to the one specified, the applicant should also describe the effect of the change on other work.

If the building consent authority has existing knowledge about a suggested alternative, or an already-evaluated building product or system, justifying its compliance can be a simple matter.
