When exterior work needs notices
PSCAA requires notice before removing 48 square feet or more of friable material per structure per year, and cement siding falls in that group. Intact nonfriable roofing does not need a notice unless it is sanded, ground or sawn, which turns it into friable material. Contractors also notify L&I above 48 square feet.
Demolishing a garage or shed with more than 120 square feet of roof needs an AHERA survey and a demolition notice whatever the siding is made of, followed by a 10-day wait.
Exterior work sometimes uncovers more; testing and remodel abatement covers the survey side, and Marysville Asbestos Removal lists every service.
