Every state, both tools

Late-fee caps, grace periods, and rent increase limits are set state by state — and sometimes city by city on top of that. This hub is the front door to ValidNotice’s US state-law library: pick your state below for a dedicated late fee calculator with that state’s cap pre-selected, or a rent increase limit checker with that state’s rules. Every state page explains the governing statute in plain language, cites its sources, and links to the comparison tables.

Frequently asked questions

Which states cap late fees?

About half of US jurisdictions set no statewide late-fee cap at all — there, the lease clause controls (subject to reasonableness). The rest cap fees as a percentage of monthly rent or a flat dollar amount, and several add a grace period before any fee may be charged. The 50-state comparison table below lists every cap, grace period, and statute.

Which states limit rent increases statewide?

In our verified data, California, Oregon, and Washington have statewide percentage caps, and the District of Columbia has districtwide rent stabilization. Everywhere else, limits — if any — come from city or county ordinances, so check local rules even in states with no statewide cap.

How current is the state-law information on these pages?

The late-fee and rent-cap datasets behind these pages were verified in October 2026 against state statutes and official legislature sources, and each page carries its verification date. Laws change — confirm the current rule locally before acting on it.

Is this legal advice?

No. These pages provide general legal information based on statewide research. They are not legal advice and do not create an attorney-client relationship. Consult a local landlord-tenant attorney with questions about your situation.
