Home Inspection permits in Washington
What Washington building departments require for home inspection, what it adds to a $413 – $826 project, and how the rules differ across 9 cities we track in the state.
The Washington permit process, step by step
Confirm whether your scope is permitted work
In Washington, structural, electrical, plumbing, mechanical and most exterior envelope work on home inspection projects triggers a permit. Cosmetic, like-for-like repairs often do not.
Let the licensed contractor pull it
A contractor who asks you to pull an owner-builder permit is shifting liability to you. Whoever pulls the permit is responsible for code compliance.
Budget for fees and plan review
Permit fees are usually a percentage of job valuation plus a flat plan-review fee. On a typical Washington home inspection project of $413 – $826, expect permitting to be a low single-digit percentage of the total.
Schedule inspections before you close things up
Rough-in inspections have to happen before drywall, backfill or roofing covers the work. A missed inspection can mean tearing finished work back out.
Keep the final sign-off
The closed permit and certificate of completion belong in your home file — buyers, appraisers and insurers all ask for them on permitted work.
