Start with jurisdiction and project scope
Before applying in Bellevue, confirm whether the property is within city limits or in unincorporated county territory. Describe the complete work to the office serving that parcel, including electrical, plumbing, structural, and site changes. Building, zoning, utility, and private HOA approvals can be separate.
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.

Permit and scope questions
Bellevue requires electrical permits for adding or moving circuits, changing service panels, generators, branch circuits, EV charging stations, solar panels, and similar work beyond maintenance.
