San Diego’s housing market is expensive. Renters often worry about rising costs. In 2025, California’s laws limit how much landlords can raise rent. This guide explains the rules, exemptions, and steps for tenants and landlords.
What Are San Diego’s Rent Increase Limits for 2025?
California’s Tenant Protection Act (AB 1482), passed in 2019, controls rent increases. The law caps annual rent hikes at 5% plus the local Consumer Price Index (CPI) change, up to a maximum of 10%. For August 1, 2025, to July 31, 2026, the maximum rent increase in San Diego is 8.8%. This comes from a 5% base plus a 3.8% CPI change reported in March 2025.
Landlords can raise rent twice in a 12-month period. The total increase cannot exceed 8.8%. For example, if your rent is $2,200 per month, the maximum increase is $193.60, making your new rent $2,393.60.
Here’s a chart showing recent rent increase limits:
| Period | Maximum Rent Increase |
|---|---|
| Aug 1, 2023 – Jul 31, 2024 | 10% |
| Aug 1, 2024 – Jul 31, 2025 | 8.6% |
| Aug 1, 2025 – Jul 31, 2026 | 8.8% |
Which Properties Are Exempt from the Rent Cap?
Not all rentals in San Diego follow the rent cap. The Tenant Protection Act lists exemptions, including:
- Buildings constructed after 2010 (less than 15 years old in 2025).
- Single-family homes or condos not owned by corporations or real estate investment trusts (REITs).
- Duplexes where the landlord lives in one unit.
- Affordable housing units for low-income tenants.
- School-owned housing or certain government-subsidized units.
If your rental is exempt, landlords can raise rent without the 8.8% cap. However, they must still follow notice rules. Tenants should check their lease or consult a housing expert to confirm their property’s status.
What Are the Notice Requirements for Rent Increases?
Landlords must notify tenants in writing before raising rent. The notice period depends on the increase:
- 10% or less: 30 days’ written notice.
- More than 10%: 90 days’ written notice (only for exempt properties, as the cap prevents larger increases).
The notice must state the new rent amount and the effective date. San Diego’s local rules ensure notices are clear and fair. Always keep a copy of any notice you receive.
How Do Rent Increases Affect Tenants and Landlords?
For tenants, the 8.8% cap keeps rent increases predictable. This helps with budgeting in San Diego’s costly market. For example, a $2,500 monthly rent could increase by up to $220, totaling $2,720. However, unexpected increases can still strain finances.
For landlords, the cap limits profits, especially with rising property taxes or maintenance costs. Some may avoid new rental investments, which could reduce housing supply. The law tries to balance affordability for tenants with fair adjustments for landlords.
