Do I need approval to replace a shed or patio?

Often, yes. A new shed, patio or carport is read against today’s rules, not the ones the old structure was built under, so replacing one is new building work even when it goes back in the same spot at the same size. If the new structure falls within the limits the state sets for exempt work, it can be built without a building application. If it does not, it needs its own approval, whatever the old one had.

Does the old approval cover the new structure?

No. An approval covers the structure it was given for. It still helps, because it shows where the old structure stood and that the spot was accepted once, and a certifier will often ask for it. If the old structure never had approval, the post on approval after it is built explains what that means for the lot.

Can I replace an old carport in the same spot?

Usually, if that spot still meets today’s siting rules. Setbacks, site cover and overlays may have changed since the old carport went up, and a position that was accepted then can sit outside the rules now. Where it does, the council has to agree to the position again before the building approval is given.

Is replacing like for like just repairs?

Replacing parts, such as a few roof sheets, a gutter or a post, is often maintenance, and the states treat it more lightly than new work. Taking the whole structure down and building another is new work, even when it is replaced like for like. The line between the two varies by state, so check with a certifier or the council before you start.

What should I check before the old one comes down?

whether the old structure had approval, and where it stood
the siting rules and overlays on the lot today
easements and sewer mains under or beside it
whether the old sheeting holds asbestos, which has its own removal rules

Reading it for your own lot

RapidSiteplan reads the council and building rules for your lot from its address, checks the design against them as you place it, lets you edit it as often as you like, and prints the site plan. Site plans and assessments in minutes. Draw the new structure where the old one stood and the plan shows whether that spot still meets today’s rules.

Search your address, or see what the plan shows for a shed, patio or carport. The Moreton Bay page lists what we hold for that council, and site plans by council covers the rest of Australia.

Common questions

Do I need approval to replace a shed or patio? Often, because a new structure is read against today’s rules, not the ones the old one was built under. If the new one falls within the limits the state sets for exempt work, it can be built without a building application. Otherwise it needs its own approval.

Can I replace an old carport in the same spot? Usually, if the spot still meets today’s siting rules. If the old carport sat closer to a boundary than the rules now allow, the new one may need the council to agree to the position first.

If I replace like for like, is it repairs? Replacing parts of a structure, such as sheets or a gutter, is often maintenance. Pulling the structure down and building a new one is new building work, even at the same size and in the same place.
