Decks & Pergolas rules in Logan
Building a deck or pergola in Logan? Logan City Council applies the Queensland planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Most decks need building approval; small low ones may not
A low freestanding deck can be exempt from building approval if it is under 10 m², no more than 1 m above ground, unroofed, not attached to the house and has no side longer than 5 m. Most decks, especially those attached to a house or raised for a view, need building approval from a building certifier.
Key rules at a glance
| Building approval - exempt deck | Not required if under 10 m², under 1 m above ground, unroofed, not attached, no side over 5 m |
| Building approval - most decks | Required for attached or raised decks (via a building certifier) |
| Roof or enclosure | A roofed or enclosed deck needs building approval |
| Setbacks (QDC MP1.1/1.2) | Typically 6 m front, 1.5 m side/rear for lots 450 m² or larger (varies with siting rules) |
| Planning approval | Usually not needed for a house deck unless an overlay (character/flood/bushfire) applies |
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
