The survey rule before you renovate
- Survey first. The Puget Sound Clean Air Agency's notice (September 28, 2023) says to check whether a survey has already been done "regardless of age of structure," and if not, to have one done before renovation.
- Who can survey. The survey must be done by an AHERA-certified building inspector. The notice adds that "homeowners of single-family owner-occupied dwellings may conduct their own survey," and that such surveys must be accurate and comply with the regulations.
- Notification before removal. Before asbestos removal, a notification and fee go to the agency through its website.
- Who removes it. The notice says abatement must be done by a certified asbestos contractor.
The agency covers King, Kitsap, Pierce and Snohomish counties. Elsewhere in Washington, ask your local clean air agency.
Hiring and planning
- Tearing the house down? See house demolition cost in Seattle.
- Plan the survey before a kitchen remodel, siding replacement or any demolition, so testing doesn't stop work halfway.
- Older homes may also have lead paint: see lead paint rules for older homes.
- Check the contractor's registration on L&I's Verify a Contractor tool, and keep the first payment small: see contractor down payments.
