Williams Lake building permits: when you need one and how to apply
Do I need a building permit, and how do I apply?
Short answer
In Williams Lake, most construction needs a City building permit: new buildings, additions, structural renovations, suites, sheds of 10 square metres or more, and decks over 600 mm above the ground. Fences, low patios and routine maintenance do not. Email the application to building@williamslake.ca or bring it to City Hall.

How it works
The City of Williams Lake issues building permits under Building Bylaw 2274. Check your zoning first, because zoning rules still apply to work that needs no building permit.
A permit is needed for: new homes and buildings, detached accessory buildings of 10 m² (100 sq ft) or more, decks more than 600 mm (2 ft) above grade, additions and structural renovations, secondary suites, enclosing a carport, porch or sundeck, retaining walls over 1.2 m (4 ft), relocations, demolitions, and new plumbing and sprinkler systems.
No permit is needed for: fences (except retaining walls), accessory buildings under 10 m², patios 600 mm or less above grade, trellises, arbours, soil-retaining walls under 1.22 m high and signs on single-family residential parcels, landscaping and planters, and painting and routine maintenance.
Steps
- Check your lot's zoning (see the zoning lookup answer).
- Fill in the Building Permit Application and the other forms on the Building Inspection page.
- Email it to building@williamslake.ca or bring it to City Hall.
- Pay the fee and security deposit (see the fees answer).
- Request each inspection online or in writing, for example by email to building@williamslake.ca. The bylaw asks for at least 48 hours' notice for simple buildings.
Good to know
- The City's page says accessory buildings "over" 10 m² need a permit; the bylaw says those "less than" 10 m² do not. Follow the bylaw, and confirm with Building Inspection if your shed is close to 10 m².
- Gas and electrical permits come from Technical Safety BC, not the City.
- The City page asks for 48 business hours' notice for inspections; the bylaw says 48 hours. Allow the longer time.
- Not sure? Call Building Inspection at 250-392-8488.
