Open the local official sources or prepare a project checklist.

Single-Family Addition and Deck Permits

Bellevue uses the single-family addition permit for additions under 3,000 square feet, decks, detached accessory structures, pools, and several related trade scopes.

Permit and scope questions

For Bellevue, ask the permit office to confirm the current area limit and the method used to measure it and whether attachment, a roof, stairs or required exit access changes the deck review before treating this project as exempt or permit-required.

Zoning and placement

Ask Bellevue's planning or zoning office to check whether retained soil, adjacent slopes or supported loads require engineering and the pool or spa classification and the required access barrier for the proposed site and use.

Building and trade review

The permit can include clearing and grading, demolition, electrical, mechanical, and plumbing work when those scopes are part of the addition project.

Discuss your project early when: Contact Bellevue before ordering materials or starting work to resolve the current area limit and the method used to measure it; whether retained soil, adjacent slopes or supported loads require engineering; whether attachment, a roof, stairs or required exit access changes the deck review; and the pool or spa classification and the required access barrier. Bring the proposed dimensions, location and scope so the answer is tied to the project.
