What SF Property Owners Actually Need to Know About State and Local Rent Rules in 2026
If you own a rental property in San Francisco, three overlapping San Francisco rent control frameworks shape almost every important decision you make: AB 1482 (the California Tenant Protection Act), Costa-Hawkins (the state law that limits local rent control), and the San Francisco Rent Ordinance (the city’s own, longer-standing framework).
These three San Francisco rent control frameworks are not separate worlds. They interact. A property might be exempt from local rent control but still subject to AB 1482. A unit can fall under just-cause eviction protections even if it’s not subject to any rent cap. And the cost of getting any piece of it wrong — an improperly worded notice, a non-compliant rent increase, an unverified exemption claim — can run into tens of thousands of dollars.
This guide is meant to give San Francisco property owners a clear, current view of how the three frameworks work together in 2026. It is not legal advice; for unit-specific questions, you should consult a qualified attorney or a property management company that handles compliance as a system. But the framework below is the same one we use to manage compliance across our portfolio.
The Three San Francisco Rent Control Frameworks at a Glance
AB 1482 — California Tenant Protection Act. Statewide. Caps annual rent increases at the lesser of 5% plus local CPI, or 10% total. Adds just-cause eviction protections after a tenant has lived in a unit for 12 months (or 24 months in some cases). Applies to most residential rental property in California, with specific exemptions.
Costa-Hawkins Rental Housing Act. Statewide. Limits what local rent-control ordinances can do. Most importantly, it generally exempts single-family homes, condominiums (in most cases), and buildings issued a certificate of occupancy after February 1, 1995 from local rent caps. It also enables “vacancy decontrol” — meaning landlords can reset rent to market when a tenant voluntarily vacates.
San Francisco Rent Ordinance. Local. Covers most multi-unit buildings issued a certificate of occupancy before June 13, 1979. Sets annual allowable rent increases (typically far lower than AB 1482’s cap). Provides robust just-cause eviction protections. Requires registration, specific notices, and ongoing reporting through the SF Rent Board.
How San Francisco Rent Control Rules Overlap — and Why That Matters
The most common mistake we see is owners assuming that if one framework doesn’t apply, none of them do.
For example: A condo built in 2010 in San Francisco is generally exempt from local SF rent control under Costa-Hawkins. But the same condo, if held by a corporate entity (and not by an individual or family trust), is not exempt from AB 1482. The owner still faces the 5% + CPI annual cap and the statewide just-cause requirements.
Another example: A single-family home in San Francisco rented to a long-term tenant is exempt from local SF rent control. But unless the owner has provided the required AB 1482 exemption notice (with specific statutory language), the unit may lose its exemption and become subject to AB 1482’s cap.
The rule of thumb on San Francisco rent control: assume something applies until you can document why it doesn’t.
AB 1482 in 2026: The Owner’s Checklist
Who is covered
Most residential rental property in California, with key exemptions including:
- Single-family homes and condos, only if owned by an individual or a family trust (not a corporation or REIT) and the owner has served the required statutory exemption notice
- Newer construction — buildings with a certificate of occupancy issued within the last 15 years (a rolling exemption)
- Owner-occupied duplexes
- Certain affordable, deed-restricted units
- Dorms, hotels, hospitals, and other non-residential uses
What is required
- Annual rent increases capped at 5% plus local CPI, with a maximum of 10% total in any 12-month period
- Just-cause eviction protections after the tenant has occupied the unit for 12+ months
- Relocation assistance equal to one month’s rent for no-fault evictions
- Written notice with specific statutory language for exempt units — without this notice, the unit may not actually be treated as exempt
Common mistakes
- Claiming an exemption without providing the required tenant notice
- Stacking multiple rent increases above the annual cap
- Missing the 12-month tenancy threshold and unintentionally violating just-cause
- Treating month-to-month tenants as different from fixed-term — they aren’t, under AB 1482
The San Francisco Rent Ordinance in 2026: The Owner’s Checklist
Who is covered
The SF Rent Ordinance covers most multi-unit residential buildings issued a certificate of occupancy before June 13, 1979. This is the bright line.
Some key wrinkles:
- Single-family homes and condos within the city are typically exempt from local rent control under Costa-Hawkins, but are still subject to SF’s just-cause eviction protections
- Buildings built after June 13, 1979 are generally exempt from local rent control, but again — AB 1482 may still apply
- Owner-occupancy and family move-in evictions have their own specific notice and relocation requirements
What is required
- Annual rent increases are limited to a percentage set each year by the SF Rent Board (typically far lower than AB 1482’s cap)
- Just-cause eviction protections apply broadly, including to many units that are exempt from local rent caps
- Specific notice requirements — content, format, language translations, posting — must be followed exactly
- Annual SF Rent Board registration and reporting
Common mistakes
- Issuing a rent increase notice that complies with state law but fails to include SF-specific disclosures
- Misclassifying the eviction basis on a notice
- Failing to track and “bank” allowable annual increases properly
- Overlooking the unit’s covered status because the building is older but the unit was added later
Notices: The Place Where Compliance Most Often Breaks
In our experience, the single most common compliance failure isn’t intent — it’s notices. Specifically:
- Rent increase notices that don’t include the right disclosures
- AB 1482 exemption notices that aren’t served, or are served with non-statutory language
- Three-day notices that misstate the amount due, the cure period, or the manner of service
- Termination notices that don’t match the just-cause framework
- Habitability and entry notices that lack required content
Every one of these is fixable with a system. None of them are forgivable in litigation.
What “Just Cause” Actually Means in San Francisco
In 2026, San Francisco property owners are operating under two overlapping just-cause regimes — the local Rent Ordinance and AB 1482.
At a high level, just cause divides into two categories:
At-fault just cause — nonpayment, breach of lease, nuisance, criminal activity, refusal to renew similar lease terms, refusal of access, and other tenant-side reasons.
No-fault just cause — owner move-in, intent to withdraw the unit from the rental market (Ellis Act), substantial rehabilitation, demolition, or compliance with a government order.
No-fault evictions trigger relocation assistance and additional procedural requirements. Owner move-in evictions, in particular, have very specific eligibility rules, occupancy timelines, and post-eviction reporting obligations under the SF Rent Ordinance. Mistakes here are the most expensive in property management.
What Property Owners Should Be Doing About San Francisco Rent Control in 2026
1. Confirm — in writing — which framework applies to each unit
For every unit you own, you should be able to state, with documentation:
- Year of certificate of occupancy
- Ownership entity (individual, trust, LLC, corporation)
- Whether AB 1482 applies, and if not, whether an exemption notice has been served
- Whether the SF Rent Ordinance applies
- Current allowable annual rent increase
- Banked rent increase history
If you can’t produce this in five minutes per unit, you’re carrying invisible risk.
2. Standardize your notice templates — and have them reviewed annually
Notices should be templated, version-controlled, and reviewed at least once a year against current law and SF Rent Board guidance. The templates from 2020 or 2022 are almost certainly out of date.
3. Track allowable rent increases as a portfolio function
Allowable annual rent increases under SF rent control change each year. AB 1482 changes each year with CPI. Owners with multiple units benefit enormously from tracking allowable increases at the portfolio level so that nothing is left unbanked and nothing is overshot.
4. Build a just-cause decision framework before you need it
Most disputes start when an owner decides to terminate a tenancy or move into a unit. Having the framework — eligible grounds, required notices, relocation obligations, documentation — built out before the moment of decision is what separates clean exits from multi-year litigation.
5. Document everything
Communications with tenants. Habitability requests and responses. Entry notices. Maintenance work orders. Inspection reports. The most consistent factor in landlord-favorable outcomes is documentation quality.
Frequently Asked Questions
Does AB 1482 apply to single-family homes in San Francisco?
Often, yes. The exemption only applies if the owner is an individual or family trust (not a corporation) and has served the required statutory exemption notice. Without the notice, the unit is generally treated as covered.
Is my new construction building exempt from rent control?
For local SF rent control, generally yes if issued a certificate of occupancy after June 13, 1979. For AB 1482, yes only for the first 15 years after the certificate of occupancy — a rolling exemption that eventually expires.
Can I raise the rent to market when a tenant moves out?
Under Costa-Hawkins, yes — most San Francisco rental units allow vacancy decontrol when the tenant voluntarily vacates. However, this does not apply to no-fault evictions, where rent reset is restricted.
What happens if I miss a notice requirement?
The most common consequences are: the rent increase is voided, the eviction is voided, the tenant has a defense in unlawful detainer, and in some cases the owner faces affirmative damages, attorney’s fees, and Rent Board enforcement. The exposure is meaningfully larger than the cost of doing it right.
Do I have to register with the SF Rent Board?
If your building is covered by the SF Rent Ordinance, yes. Registration and annual fees are required, and noncompliance can affect your ability to raise rent or recover certain costs.
Takeaway
San Francisco rent control compliance isn’t a paperwork problem — it’s an operational system. Owners who treat it as a system have far fewer surprises, far lower risk, and consistently better outcomes when the rare dispute does happen.
At Structure Properties, this is one of the most common reasons owners come to us: they have a portfolio that’s mostly fine, but they know the compliance side is held together with duct tape and good intentions. We bring it under one roof — current templates, current law, current systems — so they can focus on the asset rather than the audit.
