DPD offers several types of permits, and the application process is relatively specific to each type. Most of these processes require you to do some research on your property and project. DPD provides online tools to help you find current information about your property, including its zoning and permit history.
Permit Intake Overview
Not all projects need the same amount of review. Smaller, simpler projects require less scrutiny, while larger, more complex projects must go through our entire plan review process.
Single Family
If you're looking to remodel your house, make an addition, convert space to an accessory dwelling unit (ADU) or build a completely new house you will most likely need a single family permit.
Multifamily
A multifamily building is one that contains more than two residential dwelling units, such as townhouses or apartment buildings, but does not contain any commercial tenants, such as retail or office spaces.
Commercial/Industrial
Any building that contains commercial tenants is considered a commercial building. Mixed use buildings with both residential and commercial uses are also treated as commercial buildings.
Demolition
Demolition generally means removal of the entire structure, although in some cases the foundation may remain to stabilize a site.
Land Use
Land use policies differ based on what zone is involved. More complex projects may require an in-person visit with a land use planner in the DPD Applicant Services Center (ASC).
Side Sewer
The City of Seattle requires that a side sewer permit be issued before work begins on all side sewers, including new installations, alterations, repairs, capping, relocations, removals, and conditional and temporary dewatering work.
Trade
Most trade permits can be obtained and processed at the Over-the-Counter desk in the ASC. The type of trade permits DPD reviews include: electrical, conveyance, boilers and pressure vessels, heating, refrigeration, side sewer, plumbing, fire alarms, signs, awnings and billboards.
