Snohomish County Planning and Development Services (PDS) is responsible for reviewing and issuing a wide variety of permits and land use applications, including: residential and commercial building permits, boundary line adjustments, subdivisions, driveway aprons to the right-of-way, clearing and grading, public events, firework stands, and others. PDS strives to make the permitting process as painless and as easy to understand as possible.
