Patio approval in Brisbane
Brisbane's patio and deck rules are mostly about overlooking: privacy screens have a set openness, and a roof deck keeps away from the side boundary. A small, low, unroofed deck may be exempt building work within the state's limits, but most patios, pergolas and decks need building approval from a certifier.
The council's rules hold that a privacy screen on a deck or patio has limited openings, each kept narrow, and stands clear of the wall face. A roof deck or viewing platform stands back from the side boundary, with its floor held below a set height. The combined length of the house and every outbuilding is capped, counting decks, balconies and verandahs, so a long rear deck adds to it.
On the smallest lots private open space covers a share of the site, with an outdoor area opening directly off a main living space, so a patio there is part of how the whole house is planned. On character lots, external work is assessed against the character provisions first. An attached patio roof counts toward site cover under the state's rules.
Brisbane maps bushfire, flood, heritage and landslide, and the state adds vegetation. Landslide land usually means a soil test and engineer designed footings for a raised deck, and bushfire mapping brings a bushfire attack level assessment. Siting variations sit with the council, building approval with a private certifier or the council. Urban Utilities decides build-over near its sewer and never allows building over a maintenance hole.
The site plan shows the patio roof outline, the deck floor height, any privacy screens, the side boundary distances and the sewer.
What catches people out in Brisbane
- A privacy screen with gaps that are too wide misses the council's rule.
- Putting a roof on an existing deck ends any exemption it had.
- Decks and verandahs count toward the house's combined length.
- An attached patio roof counts toward site cover.
