Home addition planning
Educational Board planning hub for home additions in Edmonds / King & Snohomish — sequencing, permits, and hire habits without invented timelines or dollar bands.
Addition projects are permit + weather stories
Additions fail when permit ownership is fuzzy or when openings sit unprotected in North Sound weather. Freeze jurisdiction early, name who pulls permits, and require a written dry-in plan before roof or wall openings.
Use typical project phases as orientation only — ranges are “often,” not guarantees. Compare bidders with bid comparison and hiring a contractor.

Planning checklist
- Confirm city vs county permitting authority for the parcel.
- Decide bump-out vs second story vs ADU-style path before detailed pricing.
- Ask for structural engineering scope boundaries in writing.
- Require temporary weather protection and sequencing for openings.
- Clarify occupied-site staging if the primary home stays lived-in.
- L&I Verify each bidder’s contract legal name; keep screenshots in the owner file.
Home addition planning FAQ
What permits does a home addition usually need?
Structural additions typically need building permits plus related trades permits; some lots trigger site or critical-area review. Confirm with the parcel’s AHJ via the permit hub.
Second story or teardown?
See the second story vs teardown hub — compare engineering, habitability, and written dry-in plans before you chase a single number.
