An accessory building or structure is located on the same site as your home or main building but is not attached to it. These structures serve a supporting function and can provide storage, shelter, or recreational space.
Common examples include:
Before you apply
Before planning your project, consult the Land Use Bylaw to understand specific regulations for accessory buildings, including maximum height, site coverage rules, setback distances from property lines, and location restrictions.
Do I need permits for my accessory structure?
If the total area of your accessory structure is 10 m2 or larger, a development permit is required.
If it's less than 10 m2, a development permit is not required.
Safety Codes permits are required for any new electrical wiring, gas lines, water lines, or heating appliances installed in your accessory building. A building permit may also be required depending on the size, structure, and construction materials.
If you’re unsure which permits you need, contact the Building and Development Service Centre .
Apply online through E-Permitting or on paper using Forms and Checklists.
To ensure a smooth application process, refer to the Accessory Structure or Use Development Permit Checklist to confirm all requirements.
Be prepared to submit application documents, which may include:
If you applied through E-Permitting, you may follow the status of your application through the portal.
Inspections may be required and can be booked online.
How close can my accessory building be to my house?
Clearance requirements depend on structure size, construction materials, and fire separation rules.
Check the Land Use Bylaw for exact setback distances.
Do I need a permit for a pre-built shed from a hardware store?
If it is 10 m² or larger, yes.
If it is under 10 m², no development permit is required, but Safety Codes permits may still be needed for utilities.
Can I convert a shed or garage into a living space?
Not without proper permits. Living spaces require additional safety, building code, and zoning considerations. Contact the Service Centre for guidance.
Yes. Most sea-cans are considered accessory structures and require a development permit and often a building permit.
Can I put an accessory building over a utility right-of-way?
No. Structures cannot be placed on easements or utility rights-of-way. Always check your land title before planning.
