If you own rental property in San Francisco, you’ve probably asked yourself:
“How much can I legally raise the rent?”
The answer depends on several factors, including whether your property is subject to San Francisco Rent Control, California’s Tenant Protection Act (AB 1482), or exempt from both.
Getting it wrong can be costly. An improper rent increase may expose you to Rent Board petitions, repayment of overcharged rent, attorney’s fees, and unnecessary disputes with tenants.
As a San Francisco Realtor®, Associate Broker, and property management professional, I’ve helped landlords navigate these rules while maximizing the value of their investments. Here’s what you need to know in 2026.
Is Your Property Subject to San Francisco Rent Control?
The first step is determining whether your property falls under the San Francisco Rent Ordinance.
Many—but not all—rental properties are covered.
Generally, rent control applies to:
- Apartments built before June 13, 1979
- Many multi-family buildings
- Certain duplexes and triplexes depending on ownership
Properties commonly exempt include:
- Most single-family homes
- Most condominiums
- Many newer construction properties
However, being exempt from San Francisco Rent Control does not necessarily mean you can raise rent without limits.
Many exempt properties are instead governed by California’s AB 1482, which limits annual rent increases for qualifying properties.
Because every property is different, landlords should determine which laws apply before serving any rent increase notice.
How Is the Maximum Rent Increase Determined?
For rent-controlled units, landlords generally cannot choose their own rent increase amount.
Instead, the annual allowable increase is determined by the San Francisco Rent Board based on formulas established under the Rent Ordinance.
That means rising costs such as:
- Higher insurance premiums
- Property taxes
- Maintenance expenses
- Inflation
- Mortgage payments
do not automatically allow landlords to increase rent beyond the allowable annual amount.
Can Landlords Ever Raise Rent More Than the Annual Allowable Increase?
In some circumstances, yes.
Certain legally permitted increases may include:
- Capital improvement pass-throughs
- Utility pass-throughs
- Bond measure pass-throughs
- Certain operating and maintenance cost petitions
These situations have strict requirements and often involve filing with the Rent Board.
Attempting to bypass the proper process can invalidate the increase.
Should You Raise Rent Every Year?
Many landlords hesitate because they don’t want to lose a reliable tenant.
However, waiting too long can also be expensive.
If you consistently skip allowable rent increases, your property’s rental income may gradually fall well below market levels while your expenses continue to rise.
A modest annual increase—when legally permitted—often helps maintain long-term cash flow without creating a significant burden for quality tenants.

Notice Requirements Matter
California law generally requires written notice before increasing rent.
The required notice period depends on several factors, including:
- Amount of the increase
- Type of tenancy
- Whether the property is exempt
- Applicable state law
Serving an incorrect notice may delay your increase and potentially expose you to legal disputes.
When in doubt, verify your notice requirements before delivering them.
Common Rent Increase Mistakes San Francisco Landlords Make
Assuming Market Rent Equals Legal Rent
Just because similar apartments are renting for substantially more doesn’t mean you can immediately match those prices.
Rent-controlled units are governed by legal limits—not current market demand.
Forgetting About AB 1482
Many landlords incorrectly assume that exempt properties have no rent increase restrictions.
California’s Tenant Protection Act applies to many properties that are exempt from San Francisco’s local rent control.
Using Outdated Information
Rent increase rules change.
Using an old lease, outdated notice, or relying on information from several years ago can create unnecessary problems.
Raising Rent Without Understanding the Property’s Value
Sometimes landlords focus solely on increasing rent when selling may actually provide a better financial outcome.
If rising maintenance costs, insurance premiums, vacancies, or tenant issues are reducing profitability, it may be worth evaluating whether it’s time to sell.

Frequently Asked Questions
Can I raise rent whenever I want?
No. Many San Francisco properties are subject to local rent control or California’s statewide rent increase laws. Always determine which regulations apply before serving a notice.
Can I raise rent to market rate after a lease renewal?
Not necessarily. Rent-controlled properties generally remain subject to allowable annual increases unless another legal basis exists.
Can I raise rent because my insurance or taxes increased?
Not automatically. Increased operating costs alone generally do not allow unlimited rent increases.
Is every San Francisco rental property rent-controlled?
No. Some properties are exempt from local rent control but may still be subject to California’s Tenant Protection Act.

Don’t Leave Money on the Table—or Risk an Expensive Mistake
Many San Francisco landlords unknowingly undercharge rent for years, while others accidentally violate rent increase rules because they rely on outdated information or assume every property follows the same laws. Both mistakes can cost thousands of dollars.
