Good surveys answer the questions that decide cost and paperwork.
Quantities and notices
Which notices apply depends on how much there is. PSCAA counts friable pipe covering against a 10-linear-foot line and everything else friable against a 48-square-foot line, per calendar year. L&I’s separate notice begins above 48 square feet or 10 linear feet.
When the plan changes
Treat a survey as a snapshot of one scope of work. If the scope grows, say to include a second flooring layer or an extra wall, the new materials get sampled too.
What Seattle points to
On its asbestos page, Seattle Public Utilities calls for a survey ahead of any renovation or demolition and refers owners to PSCAA for the guidance and the demolition notice. For a teardown, the permit steps from the city’s construction and inspections department put the survey first.
