How it works

Cranbrook's Building Bylaw 3725 requires a permit whenever work it regulates is done. That covers constructing, repairing or altering a building, structure or secondary suite; moving or demolishing a building; installing a wood-burning appliance, a manufactured or mobile home or a swimming pool; any plumbing work; and placing a temporary building. The City's guide adds new structures over 10 m², finishing a basement and enclosing a deck, carport or porch.

The bylaw does not apply to buildings exempted by the BC Building Code, fences, routine maintenance, landscaping, paving, retaining walls under 1.2 m (unless the Building Official requires otherwise), roofless decks no more than 0.6 m above ground, and seasonal tarp or poly-covered structures. If in doubt, call the Building Inspector.

Steps

Confirm with Building Services that your project needs a permit.
Fill in and sign the Standard Building or Complex Building application.
Gather the title, owner's acknowledgement and two sets of scaled drawings, plus any extra forms listed above.
Bring everything to the office at 1212 2nd Street North and pay the $50 application fee.
Pay the permit fee in full before the permit is issued.
Arrange each inspection with a Building Official, giving at least 48 hours' notice before covering key work such as footings, foundation, framing and insulation.

Good to know

The City's pages describe applying in person only; they do not mention online submission.
The bylaw asks for 48 hours' notice for inspections, while the City's guide page says 24 hours. Follow the bylaw and confirm when you book.
A permit expires if work does not start within 12 months or finish within 24 months; a Building Official may extend it in some cases.
Starting work before the permit is issued doubles the permit fee.
Complex buildings have extra requirements, such as registered professionals and letters of assurance.
