Municipal permitting reference

How building permits work in Bellevue

Bellevue building permits are issued by the Development Services Department (DSD) under the Washington State Building Code (WSBC, 2021 IBC/IRC as adopted) and the City of Bellevue Land Use Code (LUC). The Bellevue Downtown Plan and BelRed Corridor Plan impose strict urban design standards. The Critical Areas Ordinance (CAO) protects wetlands, streams, and steep slopes; the Shoreline Master Program governs Lake Washington frontage. SEPA environmental review is required for threshold projects. Permits are submitted via Accela; inspections are scheduled through the B.O.S.S. portal.

Typical permitting sequence

  1. 1

    Verify zoning under the Bellevue Land Use Code and check Critical Areas

    Confirm the parcel's LUC district (Downtown, BelRed, NB Neighborhood Business, R-1 through R-30, etc.) and run a Critical Areas determination to identify any regulated wetlands, streams, steep slopes, or wildlife corridors on or adjacent to the site. CAO buffers and mitigation requirements can significantly affect developable area.

  2. 2

    SEPA environmental checklist for threshold projects

    Projects that exceed SEPA categorical exemption thresholds (generally: 20+ residential units, 4,000+ sq ft non-residential, or any work in a critical area) require a State Environmental Policy Act (SEPA) environmental checklist submitted to DSD. DSD issues a threshold determination; Mitigated Determination of Non-Significance (MDNS) is common for projects with conditioned mitigation.

  3. 3

    Shoreline Substantial Development Permit if within 200 ft of Lake Washington

    Work within 200 feet of the ordinary high-water mark of Lake Washington (or other Shoreline Management Act-regulated waters) requires a Shoreline Substantial Development Permit from DSD before a building permit is issued. Minor repairs may qualify for a Shoreline Exemption — confirm with DSD Planning.

  4. 4

    Submit building permit via Accela Citizen Access

    Apply through Accela with WSBC-stamped architectural and structural drawings, energy compliance (Washington State Energy Code), contractor license information, and any SEPA or Shoreline approvals. Downtown and BelRed projects must include Urban Design Review materials at this stage.

  5. 5

    DSD multi-discipline plan review

    DSD reviewers check plans for WSBC compliance (structural, fire, mechanical, electrical, energy), LUC zoning, CAO compliance, and accessibility. Downtown and BelRed projects receive Urban Design review concurrently. Correction letters are issued through Accela.

  6. 6

    Staged inspections via B.O.S.S. portal

    Schedule all inspections through the Building Online Self-Service (B.O.S.S.) portal. Required stages: foundation, framing, MEP rough-in (electrical, plumbing, mechanical), insulation, and final. Special inspections per the structural engineer of record must be documented and uploaded to B.O.S.S.

  7. 7

    Certificate of Occupancy

    After all inspections pass and any post-construction stormwater or CAO mitigation requirements are met, DSD issues the Certificate of Occupancy. For commercial projects, a final fire inspection by Bellevue Fire is required as part of the CO process.

Local considerations

  • • Microsoft and Amazon campus expansions in Bellevue operate under project-specific Development Agreements — standard DSD timelines may not apply to those parcels.
  • • The BelRed corridor is undergoing significant transit-oriented development; DSD has a dedicated BelRed project team — contact them early for complex projects in that zone.
  • • CAO critical areas determinations require a qualified biologist or wetland specialist report — commission this before architectural design begins.
  • • The B.O.S.S. portal is Bellevue's primary inspection scheduling tool — register before the permit is issued so inspections can be booked immediately.
  • • Washington State requires contractor registration with L&I (Labor & Industries) — verify registration numbers are current before permit submittal.
