When Do You Need a Permit in Bellevue?
Most structural work, additions, ADUs, decks over 30 inches, and new structures require a building permit in Bellevue. Some minor repairs are exempt — but when in doubt, check with the city or ask your architect.
Bellevue Permit Timeline (2026)
The City of Bellevue’s standard residential permit review typically takes 4-6 weeks for straightforward projects. Complex projects requiring administrative or hearing examiner review take considerably longer. Bellevue has a well-organized permit portal and generally predictable review timelines compared to Seattle.
Bellevue Residential Zoning
Bellevue uses a residential zone system (R-1 through R-30 and others) with varying lot coverage, setback, and height requirements. ADUs are permitted in residential zones consistent with state ADU legislation. The Eastgate, Factoria, and Crossroads areas have urban residential zoning that enables higher density. Coal Creek and Somerset areas are lower-density with larger minimum lots.
