Houses, Additions and Alterations

New homes, additions and structural alterations usually need a building permit. Planning approval, onsite wastewater approval and bushfire information may also be required.

Common Projects

new houses and grouped dwellings
extensions, verandahs and structural alterations
ancillary dwellings, sometimes called granny flats
internal alterations that affect structure, fire safety, exits or building classification
converting a non-habitable building or room to habitable use
earthworks, retaining walls, water tanks and stormwater works associated with the project

Start with the Site

Check zoning, setbacks, existing approvals, easements, access, levels, stormwater, servicing and whether the land is bushfire prone. W

here sewer is unavailable, coordinate the dwelling design with the approved onsite wastewater system.

Design and Certification

Your designer and building surveyor should confirm the building classification and applicable National Construction Code requirements.

Engineering, energy efficiency, smoke alarms, waterproofing, termite management, glazing and bushfire construction may need to be documented.

Ancillary Dwellings

An ancillary dwelling is self-contained accommodation on the same lot as another dwelling.

Planning exemptions and standards have specific conditions.

Confirm whether development approval is required and how water, wastewater, parking, access and bushfire requirements will be addressed.

Do Not Use a Shed as a House Without Approval

A shed or other Class 10 building is not approved for residential occupation.

Converting it to habitable use can require planning approval, a building permit or retrospective approval, engineering and substantial upgrades.

Approval is not guaranteed.
