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.
If you are 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.
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.
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.
If you are moving your business into a new space or expanding in your current location, you will likely need a permit from DPD for the construction work and/or to establish the use.
Demolition generally means removal of the entire structure, although in some cases the foundation may remain to stabilize a site.
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).
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.
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.
Street Food Vending
Regulation of street-food on private property depends on the location of the property. Multiple vendors could potentially come in under a single temporary use or construction permit, when required.
