Coordinate heating and attic access
Tell the assessor what other trades need to do and which systems must stay operational. Ask who handles shutdowns, the conditions for re-entry, and the replacement insulation after removal. Any air testing or clearance requirement should be explained as its own step. A disposal document and an authorization to reuse the room are not interchangeable records.
Survey and project requirements in Washington
Puget Sound Clean Air Agency publishes separate guidance for renovation and demolition. Have the assessor and contractor confirm the survey scope, applicable notifications and disposal arrangements for the actual property and work. A building permit does not replace the asbestos assessment.
