What are the specific NCC 2022 Class 1 building requirements for accessible housing in Australia?

NCC 2022 mandates new accessibility standards for Class 1 buildings, ensuring housing is more adaptable for diverse needs. Key requirements include a step-free path from the boundary to a dwelling entrance, wider doorways and corridors on the entry level, and a toilet and shower with specific clearances on the entry level. Additionally, internal doors must have minimum clear openings, and reinforced walls are required in specific wet areas to allow for future grab rail installation. These provisions aim to enhance liveability and future adaptability.
