Allowable Rent Increase Calculator Values Not Reflective Of New Law: New statewide rent control law AB-1482 will be in effect as of January 1, 2020. This law limits rent increases in California for specific types of properties. For your convenience, we've created a table of the maximum rent increases allowed per county for your reference and use while we work to incorporate these limits into the calculator.

Use this calculator on your website

To add this tool to your website, simply copy and paste the code below:

  • I'm being asked for the "Date of last increase". What if this is the first rent increase?+

    If this is the first time the rent been increased, under the “Date of last increase” put the lease start date.

  • Can I send rent increase notices directly from my computer?+

    The California & San Francisco Allowable Rent Increases calculator creates a 30 or 60 day notice of rent increase for you to print or email to your tenants. The rent increase notice is for non-controlled properties. You may print, sign, and mail this notice as well as email it. Please follow standard procedures to deliver notices of rent increase or seek legal advice. Delivering directly to the tenant a signed rent increase notice with proof of service is the best and most accepted means of ensuring proper delivery.

  • Why is my percent of increase higher than what I've requested?+

    Most likely you have had additional rent increases in the preceding 12 months. In California all rent increases within a one years’ time are combined together to determine the allowable rent increased based on date of notice.

  • Does the calculator round numbers?+

    Rent increases cannot be rounded up. For example, if a tenant’s new base rent is $1,093.87, the landlord cannot charge the tenant $1,093.90 or $1,094.00. However, the landlord can round down The California & San Francisco Allowable Rent Increases calculator follows this rule and will not round up numbers.

    However, following the Rent Board's published guidelines, the calculator will round up the number in the second decimal place to the next highest penny if the number in the third decimal place is 5 or above. For example, $1,093.87 x 1.7% (.017) = $1,112.46579. In this case, since the number in the third decimal place is 5, it is permissible to round up the second decimal place from 6 to 7 and the tenant’s new base rent is $1,112.47.
