How it works

The City of Nanaimo's Building Inspections section reviews plans, issues the permit and inspects the work. Building Bylaw 7224 says no one may start construction, alteration, demolition, removal or relocation without a valid permit.

Steps

  1. Check what you need. A permit is required for a detached building over 10 m² (107.64 sq ft); any structural alteration, addition, demolition or layout change; a change of layout or use of part of a house; any change to water supply or drain-waste-vent piping; and adding or moving sprinkler heads. New decks, deck covers and stairs also need one.
  2. Prepare a signed application with the owner's acknowledgement, an Appointment of Agent form if you are not the owner, and plans to scale: site plan (a BC Land Surveyor survey may be required for setbacks), floor plan, elevations and cross-sections, plus any required approvals such as sewage or highway access permits.
  3. Apply online on the City's building permit application page; all owners or their agents sign digitally. Some types (commercial new construction, demolition, non-dwelling accessory buildings, small-scale multi-unit housing) use the City's eApply system instead.
  4. Request inspections through the City's online form. Requests made by 4:00 p.m. on a business day are done the next business day. Times are not booked; inspectors can arrive any time after 9 a.m.

Good to know

  • No permit is needed for a fence (zoning rules still apply) or for retaining structures under 1.2 m. A deck needs none only if it is not the main entrance, is no more than 2 feet above grade within 4 feet of its edge, has no roof and is not attached to the house.
  • Incomplete applications cause delays. Single family dwellings can pay a $150 surcharge for review in three working days.
  • The bylaw asks for at least 24 hours' notice for an inspection. Re-inspection costs $150 when more than the normal inspections are needed. Inspections on Protection Island are only on Tuesdays.
  • Complex buildings need more, including letters of assurance from registered professionals.
  • Files over 25 MB each need arrangements with staff.

What you'll need

  • Signed application form with the owner's acknowledgement of responsibility
  • Appointment of Agent form, if you are not the registered owner
  • Plans to scale (1/4 inch = 1 foot or 1:50) and a site plan
