San Francisco Rent Control Explained

San Francisco's Rent Ordinance is one of the most complex landlord-tenant frameworks in the United States. After more than a decade representing buyers, sellers, landlords, and investors in this market, I can tell you that the single biggest source of avoidable financial loss in SF real estate is misunderstanding rent control.

This guide is the version I wish every client read before they bought, sold, or leased a unit in the city. It is written to be evergreen: the dollar amounts and annual allowable-increase percentage change each year, but the structure, decision points, and risks below do not.

💡 Local insight from Christopher — The Rent Board's website is accurate, but it is written for lawyers. Most owners I work with do not get into trouble because they read the ordinance wrong; they get into trouble because they never read it at all and trusted what a friend, a Zillow article, or an out-of-state property manager told them.

What "rent control" actually means in San Francisco

San Francisco actually has two overlapping protections governed by Chapters 37 and 37A of the Administrative Code:

1. Rent control (price control) — limits how much rent can be raised each year.
2. Just-cause eviction protection — limits when and why a tenancy can be ended.

A unit can fall under one, both, or neither. Misreading which applies is where most of the costly mistakes happen.

✔ Pro Tip — Always start with the certificate of occupancy date from DBI's public permit portal. That single document determines roughly 80% of the rent-control analysis.

The 1979 rule, in plain English

The cleanest mental model:

• Built before June 13, 1979 and has 2+ units? Treat it as fully rent-controlled until proven otherwise.
• Anything else? You are probably exempt from price control but still subject to just-cause eviction rules.

Costa-Hawkins (a 1995 state law) is what created most of the exemptions. It overrides local rent caps for single-family homes, condos, and units first certified for occupancy on or after February 1, 1995. Local jurisdictions cannot override Costa-Hawkins, even when they try.

⚠ Common mistake — Owners assume their condo is fully exempt because it was built in 2005. The price control is gone, yes — but the moment your tenant signs a lease, they get every just-cause eviction protection in the city. You cannot end the tenancy "because the lease expired."

Allowable annual increases

Each March 1, the SF Rent Board publishes the annual allowable increase. It is calculated as 60% of the CPI for the prior 12 months and historically lands between 1.4% and 2.6%, with a hard cap of 7%.

A few rules that catch people off guard:

• The percentage is set annually but applies on the anniversary of the tenancy, not on March 1.
• You must give 30 days written notice before an increase takes effect (60 days if the increase exceeds 10% — rare in controlled units, common in exempt ones).
• An increase cannot be retroactive. If you forget to serve the notice on the anniversary, you do not get to "catch up" later in that year — you can only bank it.

Banking unused increases

If you do not raise rent in a given year, the unused percentage banks and is available later. You can apply multiple banked years at once, but the total increase in any single year cannot exceed 7%.

💰 Money-saving tip for landlords — Keep a rolling spreadsheet of (a) every allowable increase since the tenancy began and (b) the actual rent in each year. Most owners I review have under-collected by 8–15% simply because no one tracked banked increases.

Capital improvement and operating-cost passthroughs

You can recover certain costs only by filing a petition with the Rent Board before collecting:

• Certified capital improvements — amortized over a defined period, capped at 10% per year and 15% over 5 years.
• Operating and maintenance expense (O&M) increases — limited to 7% per year.
• Utility passthroughs — for water and certain gas/electric increases.
• Bond measure passthroughs — for voter-approved general obligation bonds tied to property tax (50% of the bond cost in most cases).

Self-imposed "passthroughs" with no petition are unenforceable and create overpayment liability for the landlord.

Just-cause eviction: the 16 grounds

Whether or not price control applies, almost every long-term tenancy in SF is just-cause protected. There are 16 lawful grounds. The most common:

1. Nonpayment of rent — strict 3-day notice procedure.
2. Habitual late payment — pattern matters; one or two late payments is rarely enough.
3. Breach of lease — must be material and curable when applicable.
4. Nuisance — substantial interference with other tenants or the property.
5. Illegal use — narrow; nearly always requires documentation.
6. Owner move-in (OMI) — owner or qualified relative occupies for 36+ months as primary residence.
7. Ellis Act withdrawal — entire building exits the rental market.
8. Capital improvements requiring vacancy — temporary, with strict relocation rights.
9. Substantial rehabilitation — narrow and rarely usable.
10. Demolition — must have permits and follow noticing rules.
11. Lead remediation, seismic work, or government-ordered work — temporary; tenant has a right to return.
12. Owner declining to renew an expired roommate's right of occupancy — narrow.
13. Subtenant occupying without owner approval where the master tenant has moved out — fact-specific.
14. Good-faith short-term vacate for repairs — limited duration.
15. Roommate's overcrowding under building code — rare in practice.
16. Withdrawal from rental use under Ellis — duplicates #7; tracked separately by the Rent Board.

🚩 Red flag — Any landlord who tells you "the lease just expired so they have to leave" does not understand SF eviction law. There is no such thing as a no-cause termination of a long-term tenancy here.

Owner move-in (OMI) — the rule everyone underestimates

OMI evictions are legal but expensive and heavily monitored. Requirements include:

• The owner (or spouse, child, parent, grandparent, sibling, or grandchild) must occupy the unit as their primary residence for at least 36 continuous months.
• The owner must serve a strict notice, file with the Rent Board within 10 days, and pay statutory relocation assistance (currently ~$8K–$23K per tenant, with multipliers for seniors, disabled tenants, and children — updated annually).
• The unit cannot be re-rented within 5 years at higher than the controlled rent, and the Rent Board audits OMI filings.
• "Bad-faith" OMIs (where the owner moves out within 36 months without good cause) are aggressively prosecuted and have produced multi-hundred-thousand-dollar settlements.

✔ Pro Tip — If you are buying a tenant-occupied building intending to live in one unit, build the OMI cost, relocation payment, and legal review into your offer underwriting. I have seen buyers absorb $40K–$80K in unanticipated relocation and legal costs because they assumed OMI was a formality.

Ellis Act withdrawals

Ellis Act is the only way to remove every tenant in a building without "cause." It is meaningful, but the cost is significant:

• All units must be withdrawn simultaneously.
• 120 days notice (one year for elderly or disabled tenants).
• Substantial relocation payments (similar to OMI but per-unit).
• 10-year re-rental restriction at controlled rents for any unit returned to rental use within that window.
• 5-year prohibition on offering the units as TICs in some configurations.

Ellis is most commonly used today by owners moving toward condo conversion, TIC formation, or a full owner-occupied SFR conversion.

Tenant buyouts: legal, but heavily regulated

Buyouts (also called "cash for keys") are usually faster and cheaper than OMI or Ellis when both parties are willing. They are legal in SF — but only when handled correctly.

⚠ Common mistake — An owner sends a text saying "I'll give you $20K to move" and the tenant verbally agrees. That informal exchange is not enforceable and, in some cases, is itself a violation of the Buyout Ordinance. Always paper it correctly.

How rent control affects building value

This is where I spend the most time with investor clients. Two identical buildings on the same block can trade for 20–40% different prices based purely on rent roll.

Pricing rule of thumb:

📍 Local insight — A 3-unit Edwardian in the Mission with one $1,200/month tenant in place since 1998 may sell for 25% less than the same building delivered vacant. The "discount" is the market's estimate of how long the under-market tenancy will persist and what it will cost to resolve.

If you are weighing different ownership structures (condo, TIC, SFR conversion), see our companion guide Condo vs TIC vs SFR Comparison in the First-Time Buyer Guide.

Condo conversion and rent control

San Francisco's condo conversion lottery is effectively closed for most buildings, but the Expedited Conversion Program (ECP) still allows some 2-unit buildings and small-building TICs to convert. Rent-controlled tenants in converting buildings get:

• Lifetime leases in many cases.
• Right of first refusal to purchase their unit.
• Continued rent-control protection until they voluntarily vacate.

Buyers of a converted condo with a lifetime-lease tenant should price the unit as effectively non-vacant indefinitely.

Buying a building: the rent-control due-diligence checklist

✔ Before You Write an Offer

• Pull the certificate of occupancy date.
• Request the rent roll, current leases, and last 3 years of allowable-increase notices.
• Confirm the original move-in date for every tenant (this drives banked increases and protection status).
• Search Rent Board petition records for the address.
• Request 3R reports and DBI permit history — unpermitted units carry massive rent-control risk.
• Ask whether any unit has had a buyout filing (affects future condo conversion eligibility).
• Verify whether any unit is an in-law / ADU that may have been legalized under SF's amnesty program (changes rent-control status).

A property I priced last year looked like a great deal at $1.65M for a 3-unit. Pulling the buyout record showed two filings in the last decade — which permanently disqualified the building from the Expedited Conversion Program. The "great deal" was actually 8% overpriced once you understood the exit was capped.

Common mistakes I see — landlords

• Raising rent by the percentage they "heard" instead of the official annual rate.
• Skipping the 30-day notice requirement and serving by text.
• Charging utility passthroughs without filing the petition.
• Letting a rent-controlled tenant add roommates without screening — and losing the ability to reset rent when the original tenant moves out.
• Doing a soft-story retrofit without a temporary-relocation plan.
• Buying a building with an unpermitted "bonus" unit and assuming it is rent-control-exempt.

Common mistakes I see — tenants

• Signing a buyout agreement before reading the mandatory disclosures.
• Accepting a "lease renewal" with a higher rent that exceeds the allowable increase.
• Not requesting the rent history before challenging an increase.
• Subletting at market rate, which can be grounds for eviction.
• Assuming the new owner can change the rules after a sale.

Soft-story, retrofits, and temporary relocation

SF's Mandatory Soft-Story Program required seismic retrofit of most wood-frame buildings with five or more units and certain three-and-four-unit buildings. Retrofits often require temporary tenant relocation — and the cost of that relocation is on the owner, not the tenant.

💡 If you are buying a building that has not yet completed its retrofit, price in the full cost — not just the construction bid, but the relocation, lost rent, permitting, and engineering.

How rent control affects sellers

If you are selling a multi-unit building, the right buyer is not "everyone." It is a narrow pool:

• Owner-users (TIC partners, family compounds) — pay the highest price per door when the building delivers vacant or has cooperative tenants.
• Long-term hold investors — focus on in-place cash flow.
• Value-add investors — focus on the spread between in-place and market rents and a realistic plan to close that gap legally.

Pricing strategy depends on rent roll, not square footage. A vacant 3-unit in Noe Valley often outsells a fully occupied 4-unit at a higher price per door because the buyer pool is materially different.

✔ Selling soon? Run the numbers with the Seller Net Proceeds Calculator before you decide whether to deliver vacant, partially vacant, or fully tenanted.

Frequently asked questions

Does rent control transfer when a building is sold? Yes. Rent control attaches to the unit, not the owner. Every existing tenancy, rent history, and protected status survives the sale.

Can I raise rent more than the allowable amount if I do major upgrades? Only through a certified capital-improvement petition with the Rent Board. Self-help increases are unenforceable.

Can I refuse to renew a fixed-term lease? You cannot end a tenancy without just cause, regardless of whether a fixed term has expired. The tenancy converts to month-to-month and continues.

Can a long-term tenant pass the unit to a family member? Sometimes. Family members who lived in the unit before the original tenant vacates may have succession rights. Rules vary by lease type and family relationship — always get legal review.

Do short-term rentals (Airbnb) count? No — and converting a long-term tenancy to short-term rental triggers separate Office of Short-Term Rentals enforcement and significant penalties.

Are accessory dwelling units (ADUs) rent-controlled? Newly legalized ADUs built under SF's ADU ordinance are subject to the Rent Ordinance, including price control if the primary building is pre-1979.

Working with Christopher

Rent control determines whether a building is a great investment or a 20-year headache. Before you buy, sell, or restructure a tenancy in San Francisco, the cost of a thorough review is trivial compared to the cost of getting it wrong.
