Local rules
The rules we check your estimate against
A ScopeCheck audit looks up the home’s state and county from the address or ZIP code and checks each estimate against the rules below. Every rule was read from its official source, and the report only states legal requirements that are on this page. Pick a state.

We don’t have verified Washington rules on file yet, so a report for a home here states no state legal requirements. It still flags what an estimate leaves out, and tells you to confirm permits with the local building department and licensing with the state board.
