Deck & pergola rules in Queensland (2026)
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 |
Conditions & eligibility
- The deck must be detached from the house to use the exemption
- No point of the deck floor more than 1 m above natural ground level
- Floor area under 10 m² and no side longer than 5 m
- Must be unroofed and not enclosed
- Must still comply with the NCC and Queensland Development Code for structural adequacy
- Council planning-scheme overlays can add requirements
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.
How approval works in Queensland
Building approval (from a private building certifier) is the usual trigger. 'Accepted development' listed in Schedule 1 of the Building Regulation 2021 does not need it. Planning approval is usually not required for a house deck, but check the council planning scheme for overlays such as character, flood or bushfire.
Queensland has no single statewide zoning rulebook; each council's planning scheme sets overlays and siting, so confirm with your council or certifier.

Frequently asked questions
Do I need building approval for a deck in Queensland?
Only some decks are exempt. A deck can avoid building approval if it is under 10 m², less than 1 m above ground, unroofed, not attached to the house and has no side over 5 m. Most decks, especially attached or raised ones, need approval from a building certifier.
Can I build a deck without council approval in QLD?
A small, low, detached deck meeting the accepted-development limits needs no building approval, and a house deck usually needs no planning approval. Check your council's planning scheme for flood, bushfire or character overlays that can change this.
Does a roofed deck need approval in Queensland?
Yes. Adding a roof or enclosing the deck removes the exemption, so a roofed deck or patio needs building approval from a certifier.
