Q: What to do for projects on hold / awaiting DA? A: Speak with your certifier. Discuss timings and options unique to each project and devise the best way forward. There is a guideline for transitional arrangements that outlines how Section 37 of the Building Act 1975 may apply.


Q: After the project is engaged for BA, can we change the plans? A: Minor changes for the initially submitted plans will be acceptable. If there is a full re-design, as per the government guidelines (Section 37(1) (d) updated plans must be made in accordance to the new legislation. Q: What exemptions may apply? A: For affected projects engaged for BA after October 1st 2023, use the free online legislation to decide– no login required.

  • Access QDC MP 4.5 - the exemptions mean the work is exempt from Livable Housing Design Standards (LHDS).

Excerpt from p6 of the QDC MP 4.5 document.

"Ending 31st March 2025, the livable housing design provisions in Part H8 of the BCA (NCC, Volume 2) and P1 to P4 and A1 to A4 in Chapter 2.1 do not apply to the lawful carrying out of building work and assessment of a building development application for building work for: a) an affected dwelling b) a class 1a building that is located or is to be located on an affected lot"
  • Read also NCC Volume 2 section H (for housing!) for clauses that outline exemptions from the Livable Housing Provisions.

Surviving the implementation of the new code from Oct 1st 2023

The majority of 1a projects, including most extensions, renovations, raise / build in under, new dwellings will be impacted.

1. Read QDC MP 4.5 line by line to understand requirements. Bookmark to your PC for easy access and use with new projects. There are exemptions, such as for blocks with 12.5m street frontage or under, and for minor repairs.

Apply legislation layers, cross checking requirements throughout the process - start from QDC MP 4.5 to apply exemption criteria. More in the this Master Builders checklist. See page 18 of the Livable Housing Design Standard for further information about location of noggings for shower walls.

2. Communicate proactively via the plans, addressing challenges early. For example, have a livable housing design guide page with all documentation clear and concise. This might include step free entry, corridors, door widths and circulation spaces so plans can be clearly checked against the code.
