The City's page lists new buildings, additions, structural alterations, change of use, decks, basement finishing, retaining walls, fireplaces, pools and accessory buildings.
Applications currently go to the Regional District of Kootenay Boundary. The City says it will launch a new online application and tracking system but gives no date, so check its Building Permits page for the current method.
