In general building permit is required before any building work can commence. The defination of work in section 3 of the Act includes:
a. the construction, erection, assembly or placement of a building or an incidental structure; or
b. the renovation, alteration, extension, improvement or repair of a building or an incidental structure.
‘Incidental structure’ is defined under the Act as a structure attached to or incidental to a building. Therefore the placement (installation) of solar panels attached to or incidental to a building is
considered building work requiring a building permit – unless an exemption applies.
Compliance with applicable building standards Solar panels must resist the appropriate wind loading, be securely fixed down and comply with applicable building standards to the satisfaction of the building surveyor. Where a building permit is required, a registered building surveyor will issue a Certificate of Design Compliance (CDC) to certify compliance with applicable building standards.
