Calculate allowable rent increases, required notice, and comply with your state's laws
AB 1482: 5% + local CPI or 10%, whichever is lower. Applies to most multi-family built before 2005.
Raising rent is one of the most common — and legally fraught — tasks a landlord faces. The math is simple: subtract the current rent from the new rent to get the dollar increase, then divide by the current rent to get the percentage. But the legal requirements around how much you can raise rent and how much notice you must give vary enormously by state, and sometimes by city.
For landlords in states without rent control (the majority), there is no cap on how much you can raise the rent — as long as you give proper notice and wait for the current lease term to expire. Month-to-month tenants must receive notice at least equal to the state minimum (often 30 days) before the increase takes effect. Tenants on fixed-term leases generally cannot have their rent increased until the lease renews, at which point you can set any new amount you choose.
Rent control and rent stabilization laws typically apply only to specific types of properties — usually older multi-family buildings in specific cities. California's AB 1482 is one of the broadest statewide laws, capping increases at 5% plus local CPI (maximum 10%) for most multi-family buildings built before 2005. Oregon similarly caps increases at 7% plus CPI. If you own property in a jurisdiction with rent control, the allowable increase is often set annually by a local rent board.
Notice requirements vary by state, but common methods include personal delivery, posting on the door plus mailing, or certified mail. The notice must state the new rent amount and the effective date. Some states require the notice to include specific language or be on a specific form. VerticalRent automates the correct notice format for your state and tracks delivery confirmation.
Generally no — a fixed-term lease (e.g., a 12-month lease) locks in the rent for the duration. You can only increase rent when the lease renews or converts to month-to-month. Always check your lease for language about renewal terms.
This varies widely. Louisiana requires only 10 days; Washington state requires 180 days for increases of 10% or more. Most states fall in the 30-60 day range. This calculator shows the minimum required notice for your state.
In most states with rent control, single-family homes are exempt, as are condos and many newer construction buildings. California's AB 1482 explicitly exempts single-family homes not owned by a corporation or REIT. Always verify local ordinances, as they may be stricter.
Yes, but increases must be approved by the local housing authority. You submit a request with the proposed new rent, and the housing authority evaluates whether it meets the "reasonable rent" standard for your area. They may approve, counter, or deny the increase.
An improperly noticed rent increase is generally unenforceable. The tenant can refuse to pay the higher amount, and a court will likely side with them. In some states, improper notice can also expose you to penalties or give the tenant grounds to terminate the lease without consequence.
