The cost of a building permit depends on the cost of the job (labor AND materials). The permit fee schedule is available on the Permits & Fees tab of the Building Inspection page. A permit for work that does not require a formal plan review such as minor alterations, fences, siding, windows, roofing, etc. is typically issued at the Inspection Services counter while you wait. Permits for new commercial, industrial and residential construction, building additions, substantial remodeling, decks, garages and pools require plan review time which varies from 3-15 business days, depending on the project.
