Livable Housing Design under NCC 2022: what's actually required
The ABCB Standard for Livable Housing Design 2022 is referenced in NCC 2022 Volume One Part G7 (Class 2 apartments) and Volume Two Part H8 (Class 1a houses). It's based on the Silver level of the Livable Housing Design Guidelines, and it's a lower bar than full AS 1428.1 accessibility, aimed at making a home easier to enter, move through, and adapt later, particularly for older residents and people with reduced mobility.
The six core requirements
Step-free access path from the property boundary, garage or accessible parking space to the entrance: minimum 1000mm wide, maximum 1:14 gradient (or 1:20 over runs up to 15m), with landings at least 1200mm long.
A step-free dwelling entrance, minimum 820mm clear opening, level or gently ramped threshold, and a 1200mm x 1200mm external landing.
Accessible internal doors and corridors to key ground-level rooms: 820mm clear door openings, 1000mm corridor width.
A ground-level sanitary compartment with adequate circulation space beside and in front of the pan.
At least one hobless shower on the entry level.
Reinforced walls around compliant bathrooms, so grabrails can be added later without demolition, even though they aren't required at construction.
It varies by state
The national baseline took effect 1 October 2023. Victoria followed from 1 May 2024, Queensland phased it in under the Queensland Development Code from 1 October 2023, and Tasmania delayed full implementation to October 2024–2025. NSW and the Northern Territory align broadly with the national timeline. Always check current requirements with the relevant building authority before relying on a specific date.
Why it's worth building to, not just complying with
Livable housing features reduce the odds of an expensive retrofit later, support residents who want to age in place, and in a growing number of NSW developments are now a mandatory planning requirement rather than a nice-to-have.
