Before you raise the rent — check the rules

Rent increases are regulated differently everywhere. Some states and cities have rent control or rent stabilization that caps how much (and how often) you can raise rent. Most places also require advance written notice — commonly 30, 60, or 90 days depending on the increase size and your location.

You generally cannot raise rent mid-term on a fixed-lease unless the lease allows it, and increases can never be retaliatory or discriminatory under fair housing law.

This calculator only does the math. Check your state and local law and your signed lease for the maximum allowed increase and the required notice period before sending anything.

This tool is for general educational and informational purposes only. It is not legal advice and does not account for rent-control laws, notice requirements, or your lease. Consult your local statutes and a qualified attorney before increasing rent.
