Overview

The Housing Alterations Code streamlines approval for alterations, additions, and ancillary works to existing dwelling houses on eligible residential land—when changes are modest and meet prescriptive measurements. This pathway is useful for renovations, extensions, decks, garages and similar works that fall short of triggering a full DA.

Typical Works Covered

• Internal reconfigurations that do not change external envelope beyond limits.
• Ground-floor or first-floor additions within height & setback envelopes.
• New or enlarged attached/detached garages, carports, awnings, patios, pergolas.
• Minor external alterations (windows, cladding) within area thresholds.

Key Standards Themes

Controls typically regulate gross floor area added, wall & roof height, boundary setbacks, overlooking/privacy screens, stormwater disposal, protection of trees, and construction in flood or bushfire contexts.

When a DA Is Needed

Exceeding numeric standards, affecting a heritage item/area, encroaching on easements, or proposing work on environmentally sensitive land will disqualify a project from this Code.

Frequently Asked Questions (FAQs)

Q: Can I add a second storey under this Code?
A: Yes, if height, setbacks, and overshadowing controls are met; otherwise lodge a DA.

Q: Do BASIX and building code requirements still apply?
A: Yes—Code compliance doesn’t remove other statutory obligations.
