@gardenroutebuilder Yes! While minor internal renovations don't require NHBRC enrolment, building a new habitable dwelling (including a second dwelling / granny flat) or a major structural addition that requires municipal building plan approval falls squarely under the Housing Consumers Protection Measures Act. Both you as the builder must be NHBRC-registered AND the specific home/dwelling must be enrolled prior to construction starting, plus if the client is using a bank building bond, the bank will not release a single progress draw without the NHBRC enrolment certificate.
