Langley City permits for decks, sheds, carports and garages
Do I need a permit for a deck, shed, carport, or garage?
Short answer
In Langley City, a detached shed or accessory building of 10 square metres or less needs no building permit, but anything larger does. A garage needs one, as do carport or garage conversions and any sundeck. Even without a permit, you must meet zoning setbacks.
Key facts
| Sheds | A detached shed or accessory building of 10 m² or less in plan needs no building permit (it must still meet zoning setbacks); anything larger needs one.Sources differ: The guide says 'under 10 m²' and '10m2 or larger' while the bylaw says '10m2 or less'; they differ at exactly 10 m².

| Decks | Bylaw: a building permit is needed for a sundeck, or for enclosing an area above or below an existing sundeck.

How it works
Under the Building and Plumbing Bylaw, a detached building of 10 square metres or less in plan needs no building permit, and anything larger does. A garage or carport is a building, so it needs a permit unless it is detached and 10 square metres or less. Enclosing a carport into a garage or living or storage space, or converting a garage to living or storage space, also needs one.

Good to know
- Decks: the bylaw requires a permit for a sundeck, or for enclosing an area above or below an existing sundeck, with no height threshold. The City's deck guide says a permit is needed for a deck more than 2 feet above the surrounding finished grade, or a cover over an existing deck. Because they differ, confirm with the Building Division before building a low deck.
- A shed of 10 square metres or less must still meet zoning setbacks.
- In the R1 zone, an accessory building may be up to 4.6 metres high, with total accessory floor area up to 60 square metres. Setbacks are 6.0 metres front, 1.5 metres rear, 1.5 metres interior side and 3.0 metres exterior side. Overall lot coverage for all buildings is 36%. It must be at least 1.0 metre from the house and no closer to the front lot line. Other zones differ; check the Zoning Bylaw.
- The City's 2022 guides quote older zoning figures from the repealed bylaw; do not rely on them.
- Watercourse setbacks and floodplain rules may also apply.
