How this state changes the estimate

Applicable calculation

Covered AB 1482 properties are limited to the smaller of 10% and 5% plus the applicable regional CPI over twelve months. Exemptions and stricter city rules matter. San Francisco rent-controlled units and Los Angeles RSO units use local systems; LA’s July 2026–June 2027 ordinary allowance is 3%.

The result includes only the rule components identified in the calculation. Local additions, negotiated payer allocations and exemptions require confirmation for your transaction.

Coverage and local differences

Covered AB 1482 properties are limited to the smaller of 10% and 5% plus the applicable regional CPI over twelve months. Exemptions and stricter city rules matter. San Francisco rent-controlled units and Los Angeles RSO units use local systems; LA’s July 2026–June 2027 ordinary allowance is 3%.

Confirm eligibility using the primary source and local office. A purchase, property classification, tenancy type or exemption can change which rule applies. Enter documented local costs and rates rather than carrying a previous owner’s assumptions into the new deal.

Dates and review status

The source record was checked on 2026-09-30. Numeric inputs are planning assumptions unless a checked schedule is explicitly applied.

Independent professional review is pending. Confirm that the source’s effective period covers your closing or tenancy date.

Worked example

Follow the default numbers.

With monthly rent of $2,400, the model gives new monthly rent: $2,520.

The formula is new rent = current rent × (1 + increase). Open the breakdown to trace expenses and assumptions. Change one input at a time to see how your decision changes. This example uses scenario inputs; it is not an offer, tax bill, appraisal or legal determination.

Percent, dollars and the new rent

The same change can be expressed three ways. Divide the dollar increase by the old monthly rent to find the percentage. Multiply the old rent by the percentage to find the dollar increase. Subtract old rent from proposed rent when you already know the new price. The multi-year table compounds the calculated percentage annually. It is a projection, not permission to repeat an increase.

Coverage comes before the cap

Select the state and any listed local system, then confirm whether the property is covered. California’s statewide AB 1482 limit is the smaller of ten percent and five percent plus the applicable regional CPI. Oregon and Washington publish annual percentages. Local rent control can be stricter. Exemptions depend on property age, ownership, notices, subsidy programs and other facts that the calculator cannot determine.

Dates change the applicable rule

A rent cap belongs to an effective period. The calculator refuses to present an annual percentage as current outside its recorded period. New York City apartment guidelines depend on the renewal start date and lease length; they are not a statewide rate. Notice requirements are also separate from the allowed percentage. Prior increases during the same twelve-month period can reduce the remaining headroom.

Check the actual notice

The displayed notice interval is a planning reminder, not a completed legal notice. Service method, weekends, renewal deadlines and tenant protections can affect the earliest lawful effective date. Confirm the current statute or rent-board order linked below before serving a notice. When the source does not establish a numeric cap, the result reports that the rule needs checking rather than treating the absence of a preset as unlimited permission.
