There have been changes to the BCA and NCC Regulations in regard to the slip resistance requirements for residential stairs. The new standard specifies that the old testing method of R-ratings (R9, R10, R11, R12) be replaced with P-ratings (P0, P1, P2, P3, P4 and P5). Coatings used on stairs must meet or exceed a
P3 for dry surfaces and P4 for wet surfaces.
Once your building is considered to be suitable for occupation, an application for an occupancy permit / certificate is made to the relevant building surveyor. The building surveyor may request certificates or statements from various practitioners involved in the construction of the building to confirm that the building work complies with relevant building legislation. Having this certificate/permit signifies that a building surveyor is satisfied that the completed building work is safe and suitable for occupation.
