Santa Monica has some of the strictest rent control in California. Under the city's Rent Control Charter Amendment, annual increases are limited to 75% of the CPI (Consumer Price Index).
For 2025, the LA metro CPI is approximately 3.5%, so Santa Monica's maximum allowable increase is:
- 75% × 3.5% = 2.625% maximum
- On $3,200 rent = $84 maximum increase to $3,284
Your landlord's proposed $256 increase (8%) is more than TRIPLE the legal maximum. This increase is illegal.
You can use a rent control calculator to verify the exact maximum based on current CPI.
