Lease renewal is one of the most important and most mishandled transactions in property management. Getting it right — proper notice, correct language, compliant documentation — protects landlords from costly disputes and keeps good tenants. A properly drafted renewal letter is the foundation of a smooth renewal process.

Notice requirements by state. States impose minimum notice periods for renewals and rent increases that vary from 30 to 90 days. California requires 90 days notice for rent increases over 10%. Failure to give proper notice can void the rent increase or create tenancy issues. This generator automatically applies the correct notice period for your state.

Rent increase strategies. Modest annual increases of 3 to 5% are generally better received than large infrequent increases. The cost of turnover — lost rent, cleaning, repairs, leasing fees — typically exceeds several months of rental income. If market rents have risen significantly, communicate that context: most tenants will accept a reasonable increase if they understand the alternative.

Month-to-month vs. fixed-term renewal. A fixed-term renewal gives the landlord rent certainty and makes it harder for the tenant to leave without penalty. A month-to-month arrangement gives both parties flexibility but creates uncertainty. For stable, long-term tenants, fixed-term renewal is usually preferable for both parties.

What to include in the renewal letter. A complete renewal letter includes: current lease expiration date, new lease term, new monthly rent, deadline for the tenant to respond, any changes to terms or rules, and signature lines. If any terms are changing beyond rent, document those changes in writing.

Addendum vs. new lease. For simple renewals with minor changes, a lease renewal addendum is appropriate and simpler than a new lease. For significant changes — new roommates, different unit, major policy changes — a new lease is better practice. The addendum should reference the original lease and be signed by all parties.
