BUILDING BYLAW 3590-2003 This document is a consolidation of "District of Mission Building Bylaw 3590-2003" with the
The City of Mission regulates construction under Building Bylaw 3590-2003.

How it works

The City of Mission regulates construction under Building Bylaw 3590-2003 and the BC Building Code. Inspection Services reviews applications and inspects the work. No one may start construction work without a valid permit.

A permit is needed for new construction, additions (including adding or increasing a deck), alterations and renovations (such as a secondary suite or finishing a basement), plumbing and sprinkler work, detached buildings over 15 m², pool houses of any size, retaining structures over 0.6 m, demolition, moving a building, solar panels, swimming pools, change of use and tenant improvements.

Steps

  1. Check whether your project needs a permit, or ask Inspection Services.
  2. Start with a Pre-Submission Review. The City checks that planning and engineering matters are settled and the application is complete before it accepts it.
  3. Pick the checklist for your project type and gather the forms and plans from the Form Library.
  4. Pay the non-refundable application fee. The application then gets a permit number and joins the queue for detailed code review.
  5. Pay the balance of the permit fee before the permit issues, then book inspections online with your 8-digit permit number (each permit number needs its own booking).

Good to know

  • No permit is needed for roofing, cladding, painting, flooring or minor plumbing repairs.
  • Accessory buildings: the bylaw exempts a single-storey accessory building or unmodified shipping container serving a one- or two-family home if it is 15 m² (161.4 ft²) or less. The City's page also lists pool houses (sheds) as needing a permit regardless of size, so confirm with Inspection Services before building one.
  • Inspections need 24 hours' notice; requests after 3:00 p.m. are processed the next business day. To cancel or reschedule, phone 604-820-3726 by 9:00 a.m. on the inspection day.
  • All new construction needs an automatic sprinkler system under Fire Sprinkler Bylaw 5679-2017; renovations, additions and accessory buildings may be affected.
  • Electrical and gas permits come from Technical Safety BC (1-866-566-7233), not the City.
  • Current review wait times are on the City's wait times page; they change, so check before you apply.

What you'll need

  • Building Permit Application form and Owner's Undertaking form (from the City's Form Library)
  • A title search printed within 30 days, plus copies of registered covenants and easements
  • At least 2 sets of scaled plans (site plan, floor plans, elevations, sections, details), with sealed engineering, stormwater or sprinkler plans where the checklist for your project asks
