Decks & Pergolas rules in Canterbury-Bankstown
Building a deck or pergola in Canterbury-Bankstown? City of Canterbury-Bankstown applies the New South Wales planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Often no approval needed if within exempt limits
A deck, balcony or patio can be built as exempt development, with no DA or CDC, if it is no more than 25 m² in floor area, sits no higher than 1 m above ground, is behind the front building line and set back at least 900 mm from side and rear boundaries. Bigger or higher structures need a Complying Development Certificate or a Development Application.
Key rules at a glance
| Max floor area (no approval) | 25 m² (combined for all decks/balconies/patios on the lot) |
| Max height above ground | 1 m (finished floor above existing ground level) |
| Setback from boundary | At least 900 mm from side and rear boundaries; behind the front building line |
| Pergola (roofless) | Exempt up to ~25 m² and 3 m high with the same setbacks |
| Rural zones setback | 5 m from each boundary in RU1-RU6 and R5 zones |
| Heritage / overlay | Exemption does not apply on heritage items, in conservation areas or on environmentally sensitive land, so approval is needed |
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.
