What this means in practice

Put the rent increase in writing, state the new amount and the date it takes effect, and keep a copy along with proof of how and when it was delivered. Count the notice period from the date the tenant actually receives the notice, and check whether your state adds extra days for mailed notices.

Check local law as well as state law. Some cities and counties have rent stabilization ordinances, registration rules, or longer notice periods, and subsidized or rent-regulated units often follow separate federal or program rules.

A rent increase cannot be used to retaliate against a tenant for making a repair request or complaint, or to discriminate against a protected group. If the timing of an increase could look retaliatory, document the business reason for it.

General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
