How the state-aware tools work
The deposit letter, rent increase notice, and late fee tools read their deadlines, notice periods, grace periods, and cap rules from our state records — each one verified against official legislature sources and dated. States we haven't verified yet appear greyed out in the selectors rather than showing unverified numbers, and they switch on automatically when their records are verified. Details in how we verify.
