The District publishes clear residential thresholds, a separate commercial patio framework, and a planning layer the City does not have: hazard development permit areas.
01
Where the residential line falls
The District's deck bulletin states that decks less than 600 mm, or 2 feet, in height and detached decks less than 10 square metres, or 108 square feet, in area do not require a building permit. Above 600 mm a permit is required, sited to accessory building requirements if detached and to principal building requirements if attached to the house.
02
Attached structures affect your numbers
The same bulletin states that decks attached to the house greater than 600 mm are included in the Building Coverage calculation, and that decks attached to the main dwelling greater than 1,981 mm are included in Floor Space Ratio. On a tight lot that can matter as much as the permit itself.
03
Slope can bring in an engineer
The District's building permit requirements questionnaire asks whether you are constructing within 30 feet of a slope greater than 18 percent, and separately greater than 36 percent, and identifies a geotechnical engineer as required in those cases. It also notes that where work has been started without permits, permit fees will be increased under the Fees and Charges Bylaw.
04
Hazard areas apply to some properties, not all
Some District properties fall within development permit areas covering streamside or environmental protection, slope or wildfire hazard. The District's patio guide states that use of land within those areas is discouraged and would likely require an environment or hazard development permit. This affects specific properties, not the District generally, and the District's own mapping is the place to check.
05
Commercial patios use the OCSA framework
The District's Guide for Establishing Outdoor Customer Service Areas states that requirements differ depending on whether the patio is on public or private property. An OCSA shall not exceed 50 percent of the gross floor area of the principal use, or 50 percent of its permitted seats, whichever is the lesser. Railing, fencing or other enclosure should be between 0.9 and 1.2 metres, overhead cover or other structures may require a Building Permit, and an umbrella or canopy should keep 2.1 metres clearance above any walking surface.
