Why these are free

Landlord-tenant law is state law, and the answers are public — what a state caps a late fee at, how much notice an eviction requires, which lease clauses are void on sight. None of that should sit behind a paywall, and these tools quote the statute and the citation so you can check the source yourself.

What LeaseHelper charges for is the document: a complete, state-specific lease or notice with the correct clauses already written in. The tools tell you what your state requires; the paid product is the paperwork that complies with it.

Disclaimer: This tool provides general information about state landlord-tenant law and is not legal advice. Statutory rules are quoted from our state-variance dataset with the statute citation shown; laws change, and local ordinances may impose stricter rules than the statewide figures here. Verify the current statute before acting, and consult a licensed attorney for your situation. Dataset compiled 2026-07-08.
