Under AB 1482, landlords are limited to increasing rent by no more than 5% plus the local CPI (inflation rate) or 10%, whichever is lower. The local inflation rate is determined by the California Consumer Price Index (CCPI), which is released annually by the California Department of Finance.

Raising rent in California Landlords are allowed to raise rent by a maximum of 10% every 12 months. That means if the CPI change is above 5%, the maximum increase caps at 10%. It's vital to understand, however, that the actual amount you can raise rent depends largely on your local city laws.

If the landlord chooses to increase rent by more than 10%, they must give a 90-day notice to their tenants. It's also worth noting that landlords must give a 30-day notice to tenants who are under week-to-week leases.

Tenants have to give a 30-day notice to their landlords in California to end their month-to-month rental agreement. Your rental agreement may have specific requirements about giving notice, such as providing notice by the first of the month or another specified time frame.

In California, when rental property owners increase a tenant's rent more than 10 percent, the owner must provide the tenant with a 60-day advance written notice. For an increase in rent that is greater than 10 percent, owners must provide tenants with at least 60- days' advance notice.

California's Tenant Protection Act There is a maximum increase of 10% allowed in any given year, thus the Act's provision is often referred to as a “rent cap.” To calculate the cost of living increase that is applicable to your market, use the Consumer Price Index (CPI) published by the Bureau of Labor Statistics.
