San Francisco is unique among California counties in being a consolidated city-county — the City and County of San Francisco are one and the same governmental entity, and its landlord-tenant law applies uniformly across the entire 47 square miles of the peninsula. With roughly 875,000 residents packed into that compact area, San Francisco is California’s most densely populated county and, by almost any measure, its most legally complex rental market. The San Francisco Rent Ordinance has been in place since 1979 and covers a remarkably broad swath of the city’s rental housing stock — nearly all residential buildings with two or more units constructed before June 13, 1979. The San Francisco Rent Board, established by the Ordinance, administers a comprehensive framework of rent increase controls, eviction procedures, petition rights, and relocation assistance obligations that go far beyond anything in California state law and in many respects beyond anything in any other American city.
For landlords, San Francisco represents the highest-stakes, highest-reward, and most legally demanding rental environment in California. Rents for covered units can be extraordinarily high — a long-tenured San Francisco tenant in a rent-controlled unit may be paying rent that is a fraction of current market rate, because increases have been capped at the Rent Board’s annual allowable percentage for decades. New tenants in uncontrolled units, or in newer buildings, pay some of the highest market rents in the country. The gap between these two worlds — controlled and uncontrolled — defines much of the tension in San Francisco’s rental market. Landlords who understand the distinction between the Rent Ordinance’s rent cap provisions and its just cause provisions, who know which units are covered and which are not, and who comply scrupulously with the Rent Board’s procedures can operate profitably and legally. Those who do not face penalties that can run to six figures.

SF Rent Ordinance — Coverage
San Francisco Administrative Code Chapter 37. Covers most residential rental units in buildings with 2 or more units constructed on or before June 13, 1979 (the date the Ordinance was enacted). Also covers single-family homes and condominiums if the certificate of occupancy was issued before June 13, 1979 and they are not separately alienable. Major exemptions: newly constructed units (post-June 13, 1979), single-family homes and condos with separate certificates of occupancy after that date, units where the owner lives in the same building and the building has 4 or fewer units. Always verify coverage at SF Rent Board’s online unit lookup before taking any action.
Two-Tier Coverage: Rent Cap vs. Just Cause
The SF Rent Ordinance has two separate tiers of protection. The rent cap (limiting annual increases) applies to one set of units. The just cause eviction protections apply to a somewhat broader set. A unit may be subject to just cause protections but NOT the rent cap — typically post-1979 units that have been annexed into just cause coverage. Know which tier(s) apply to each of your San Francisco properties before taking any action on rent or eviction.
Annual Allowable Rent Increase
The SF Rent Board sets the annual allowable rent increase each year. The formula is approximately 60% of the local CPI. For 2024–2025, the allowable increase was 1.7%. This is dramatically lower than AB 1482’s formula — a San Francisco landlord with covered units who imposes the AB 1482 percentage rather than the Rent Board rate would be in violation. Check sfgov.org/rentboard each year before any rent increase on covered units.
Just Cause Eviction — Covered Units
For covered units, the SF Rent Ordinance requires just cause for all evictions without exception. Just cause grounds include: nonpayment of rent; breach of lease; nuisance; illegal use; refusal to execute a written extension; subletting in violation of the lease; refusal to allow legal entry; and no-fault grounds including owner/relative move-in, Ellis Act withdrawal, lead paint remediation, and substantial rehabilitation. Every ground has specific procedural requirements; errors render the notice void.
Owner Move-In (OMI) Evictions
SF Admin Code § 37.9(a)(8). Owner or qualified relative must intend in good faith to occupy the unit as their primary residence for a continuous period of at least 36 months. Strict limitations: cannot OMI a unit if another equivalent unit in the same building is vacant or if a comparable unit in the building has been vacated within the prior 3 years. Tenant must be given written notice including the owner’s name, relationship to owner (if relative), and statement of good faith intent. Relocation assistance required. The owner must actually move in within 3 months of the tenant vacating. Fraudulent OMI evictions expose the landlord to substantial civil liability and criminal penalties.
Ellis Act Evictions
California Government Code §§ 7060–7060.7. Allows a landlord to go out of the rental business entirely by withdrawing all units from the rental market. In San Francisco, Ellis Act requires 120 days notice to all tenants (one full year for tenants who are elderly (62+) or disabled). Relocation assistance at rates set by the Rent Board is required for all displaced tenants. Once withdrawn under Ellis Act, the property cannot be re-rented for a specified period without offering returning tenants the right of first refusal at the same rent. Ellis Act evictions are irreversible for a significant period; consult experienced SF housing counsel before initiating one.
Relocation Assistance
San Francisco imposes relocation assistance obligations for most no-fault evictions that are substantially higher than AB 1482’s one-month minimum. For Ellis Act evictions, the Rent Board sets relocation amounts annually; as of 2024–2025, the per-unit amount was approximately $9,600, with additional amounts for elderly and disabled tenants. For OMI evictions, relocation assistance is also required. Verify current amounts at the SF Rent Board before initiating any no-fault eviction.
Security Deposit
1 month’s rent maximum for most landlords (Civil Code § 1950.5; effective July 1, 2024). At SF market rents of $3,500–$4,500+/mo, the one-month cap is a very real financial constraint. Small landlord exception (≤2 properties, ≤4 units) allows up to 2 months; not applicable to service member tenants. SF also has local rules about the handling of security deposits — verify Rent Board guidance in addition to state law requirements. Return within 21 days with itemized statement and documentation.
Rent Board Petitions & Hearings
Both landlords and tenants can file petitions with the SF Rent Board. Landlord petitions include requests for above-guideline increases (for capital improvements or increased operating costs) and certification of future rent increases tied to pass-through of costs. Tenant petitions include challenges to unlawful rent increases, complaints about decreased services, and habitability disputes. The Rent Board holds hearings on contested petitions and issues binding administrative decisions. Rent Board decisions can be appealed to SF Superior Court. The Board’s administrative process is active and well-resourced.
DV Early Termination
Victims of DV, sexual assault, stalking, human trafficking, elder abuse, or specified violent crimes may terminate with written notice and documentation within 180 days of the qualifying event. Rent obligation ends no more than 14 calendar days after notice (Civil Code § 1946.7). San Francisco also has additional DV protections under local ordinance.
AB 1482 (Tenant Protection Act) requires just cause for evictions of tenants in place 12+ months. 3-day notice can only include rent - no late fees, utilities, or other charges. AB 2347 (eff. Jan 2025/2026) doubled tenant response time from 5 to 10 business days. Notice excludes weekends and court holidays.
Serve the required notice based on the eviction reason (nonpayment or lease violation).
Wait for the notice period to expire. If tenant cures the issue (where allowed), the process stops.
File an eviction case with the Superior Court (Unlawful Detainer). Pay the filing fee (~$385-435).
Tenant is served with a summons and has the opportunity to respond.
Attend the court hearing and present your case.
If you prevail, obtain a writ of possession from the court.
Law enforcement executes the writ and removes the tenant if necessary.

🔍 Reduce Your Risk Before Signing a Lease:
California landlords who screen tenants carefully before signing a lease significantly
reduce their risk of ending up in eviction court. Understanding
tenant screening in California —
including background checks, credit history, income verification, and rental references — is one of the most
cost-effective steps you can take to protect your rental property. Before you ever need California's
eviction process, proper tenant screening can help
you identify red flags early and avoid problem tenancies altogether.

🏘️ Neighborhoods & Screening Tips
Pre-1979 buildings anywhere in SF: Verify Rent Board status before any action. Use the Rent Board’s online unit lookup. Know whether your unit is subject to rent cap, just cause, or both. Never impose a rent increase using the AB 1482 formula on a Rent Ordinance-covered unit — the allowable increase is dramatically lower. As of 2024–2025, the annual allowable increase for covered units was 1.7%.
Post-1979 and new construction: Not subject to SF Rent Ordinance rent cap. AB 1482 may apply to pre-2010 construction. Units built within 15 years are AB 1482-exempt. New luxury construction (2010+) is market rate with no rent cap. Just cause eviction protections under the SF Rent Ordinance may still apply to some post-1979 units — verify at the Rent Board.
Tech industry tenants: San Francisco’s dominant tenant profile is tech professionals. RSU vesting, stock-based compensation, and signing bonuses mean base salary understates financial capacity. Request W-2 plus total compensation statement or offer letter. Verify employment directly with employer HR for major tech companies (Salesforce, Airbnb, Lyft, etc.). Job security varies significantly by company maturity and funding stage.
Owner move-in planning: If you intend to OMI a covered unit, consult a licensed SF housing attorney before taking any steps. The procedural requirements are strict, the occupancy obligations are real (36 months primary residence), and the fraud exposure is significant. Errors in OMI notices are very difficult to correct after the fact.
Long-tenured tenants in covered units: If you acquire a building with long-term tenants in covered units, request rent history from the seller. Banked rent increases may be available. Understand the base rent and when it was last increased. Banked increases (lawful increases not previously imposed) can be applied as a lump sum with proper notice.
Background checks, eviction history, credit reports — get the full picture before handing over the keys.
San Francisco Landlord-Tenant Law: Navigating the Most Complex Rental Jurisdiction in America
San Francisco’s rental market is not just the most legally complex in California. It is arguably the most legally complex residential rental jurisdiction in the United States. The San Francisco Rent Ordinance, which has been in effect since 1979 and has been amended, strengthened, and interpreted through decades of Rent Board decisions and court rulings, creates a regulatory environment that requires specialized knowledge to navigate safely. A landlord who enters San Francisco’s rental market without understanding the Ordinance — who imposes a rent increase using the wrong formula, who serves an eviction notice without the right just cause language, who initiates an owner move-in process without understanding the occupancy obligations — will encounter consequences that are not administrative inconveniences. They are financial penalties and personal legal exposure that can run to six figures and beyond.
This is not a reason to avoid San Francisco. The rents are among the highest in the country. The tenant pool is dominated by some of the highest-earning young professionals anywhere in the world. Vacancy rates, while cyclically variable, have historically been among the lowest of any major American city. Owning well-maintained rental property in San Francisco has made many landlords very wealthy over the past four decades, and the structural scarcity of housing supply in a 47-square-mile peninsula surrounded on three sides by water makes a compelling long-term demand case. But it is a reason to invest in knowledge and competent professional support before you do anything with a San Francisco rental property.
The Architecture of the SF Rent Ordinance
The San Francisco Rent Ordinance (Administrative Code Chapter 37) operates on two distinct tracks that landlords must keep separate in their thinking. Track one is the rent cap: the limitation on how much a landlord can increase rent for a tenant in a covered unit in any 12-month period. Track two is just cause: the requirement that a landlord have a legally specified reason to terminate any covered tenancy. These two protections have different coverage scopes. The rent cap applies to one set of units; just cause applies to a somewhat broader set that includes some post-1979 units that have been incorporated into the Ordinance through amendments. A unit can be subject to just cause protections without being subject to the rent cap. This two-tier structure means that verifying “Rent Ordinance status” is not a binary question with a single answer — it is two separate questions, and the answers can differ for the same unit.
The rent cap side is straightforward in principle and dramatic in financial implication. Each year, the SF Rent Board sets an annual allowable rent increase for rent-controlled units. The formula is approximately 60 percent of the local Consumer Price Index increase, and the resulting percentage has typically been very low — for 2024–2025, it was 1.7 percent. This means that a landlord with a covered San Francisco tenant who has been in occupancy for ten years can increase rent by only 1.7 percent in the current year, regardless of what market rents have done. The cumulative effect of decades of below-market-rate increases is that long-tenured San Francisco tenants in covered units may be paying rents that are a fraction of the current market rate for comparable units. This gap — between the controlled rent and the market rent — is the central economic fact of the San Francisco covered rental market, and it explains much of the political and legal tension that surrounds rent control in the city.
Owner Move-In and Ellis Act: The No-Fault Eviction Toolkit and Its Limits
The two most significant no-fault eviction tools available to San Francisco landlords of covered properties are the owner move-in eviction and the Ellis Act withdrawal. Both are legitimate and both are available. Both also carry obligations and exposure that make them unsuitable for casual or improperly motivated use.
An owner move-in eviction under SF Admin Code Section 37.9(a)(8) allows a landlord or a qualified relative (parent, child, sibling, grandparent, grandchild) to recover possession of a covered unit for occupancy as their primary residence. The critical requirements are genuine intent — the evicting party must actually intend to live in the unit as their primary residence for a minimum of 36 consecutive months — and actual occupancy within three months of the tenant vacating. The Ordinance imposes strict limitations: a landlord cannot use an OMI if another comparable unit in the same building is vacant, or if a comparable unit was vacated by another tenant within the prior three years. The tenant must receive written notice of the intended occupant’s name, relationship, and good faith intent. Relocation assistance is required. And the city actively investigates fraudulent OMI evictions — using an OMI to recover a unit and then re-renting it at market rate is a civil and criminal violation that the City Attorney’s office prosecutes.
The Ellis Act is California state law (Government Code Sections 7060–7060.7) that allows a landlord to go out of the rental business entirely by withdrawing all units from the rental market. San Francisco has enacted the most restrictive Ellis Act procedures allowed by state law. All tenants in an Ellis Act withdrawal must receive at least 120 days’ written notice; elderly tenants (62 and older) and disabled tenants are entitled to one full year’s notice. Relocation assistance at amounts set annually by the Rent Board — approximately $9,600 per unit as of 2024–2025, plus additional amounts for elderly and disabled tenants — is required for all displaced tenants. Once withdrawn from the rental market under Ellis Act, the property cannot be re-rented for a specified period without offering each displaced tenant the right of first refusal at their former rent. Ellis Act evictions are, in the most literal sense, a one-way door for a significant period; they should be initiated only after careful analysis of the landlord’s long-term plans and with experienced legal counsel.
For units that are not covered by the SF Rent Ordinance — newer construction, single-family homes with post-1979 certificates of occupancy, condominiums with separate certificates — the regulatory environment is considerably simpler. AB 1482 may apply to pre-2010 units not covered by the Ordinance, capping annual increases at 5 percent plus the San Francisco MSA CPI and requiring just cause for evictions after 12 months. Units built within the last 15 years are exempt from AB 1482’s rent cap. New market-rate construction in neighborhoods like Mission Bay, Dogpatch, and the Central SoMa corridor is largely outside both the Rent Ordinance and AB 1482, operating as pure market-rate rentals governed only by California’s Civil Code baseline protections.
