How it works

Nelson's Building Bylaw 3456 requires a permit before regulated work starts. City building inspectors enforce it along with the BC Building Code. If your property is in a Development Permit Area you may also need a development permit, and a non-conforming building may need a variance.

A permit is needed for a new building over 10 m², additions, decks and new roofs over decks, renovations and alterations, retaining walls over 1.2 m, demolition or relocation, wood-burning appliances, signs, and renovations that create a new bedroom or suite or enclose a deck. The City page also lists a new building under 10 m² that poses a risk or hazard.

Steps

Ask Development Services (250-352-8260) whether your project needs a permit, and whether a development permit or variance applies.
Get the checklist for your project type from the Building Permits page.
Fill in the online or PDF application and gather the checklist attachments.
Submit it to Development Services and Engineering on the second floor of City Hall, with the fee. PDF applications may be emailed.
Book inspections as work proceeds (see the building-inspections answer).

Good to know

Not needed under the bylaw: a fence, an accessory building under 3 m high and under 10 m² floor area, trellises, arbours and soil-retaining walls under 1.2 m on single-family parcels, and temporary plastic-covered storage or greenhouses under one storey. The City page also lists painting, landscaping, kitchen cupboards and exterior finish repair.
Inspections: book with the Development Technician at 250-352-8260. The City page says one business day's notice is enough for most; the bylaw asks for at least 48 hours, so confirm when booking.
Breaking the Building Bylaw can mean a fine of up to $10,000.
