San Francisco Rent Ordinance (Chapter 37) & Eviction Defense
If you own rental property in San Francisco, you are not just a landlord; you are operating in a highly regulated micro-economy governed by the San Francisco Residential Rent Stabilization and Arbitration Ordinance (S.F. Admin. Code § 37.1 et seq.).
Commonly referred to simply as “Chapter 37” or the “Rent Ordinance,” this single piece of legislation dictates exactly how much you can charge, who you can evict, and how much it will cost you to reclaim your own property. Navigating it without precision is the fastest way to face a wrongful eviction lawsuit and treble (triple) damages.
We help property owners cut through the red tape, defend their investments, and execute lawful, bulletproof evictions in San Francisco.
The History: The “Temporary Emergency” That Never Ended
To understand how to operate under the SF Rent Ordinance, you have to understand how it was built. In June 1979, the San Francisco Board of Supervisors passed Chapter 37 as a 15-month emergency measure to combat a sudden spike in inflation and a severe housing shortage. It was designed to temporarily safeguard tenants from excessive rent increases.
Nearly half a century later, that 15-month emergency measure has evolved into a permanent, sprawling, and fiercely defended institution. Over the decades, tenant advocacy groups have successfully amended Chapter 37 dozens of times, bolting on complex layers of protection. What started as a simple cap on rent increases has morphed into a rigid system of relocation payouts, mandatory buyout registries, and hyper-technical eviction restrictions.
How San Francisco Stands Apart in the Bay Area
While neighboring jurisdictions like Oakland and Berkeley have developed their own strict rent control laws in recent years, San Francisco remains the most complex and heavily litigated jurisdiction in the state. Unlike its neighbors, San Francisco guarantees a free, city-funded attorney to tenants facing eviction through the Eviction Defense Collaborative. This means that a minor typo on a termination notice that might slip by a judge in Contra Costa County will immediately be seized upon by a defense attorney in San Francisco, resulting in your case being thrown out and you paying the tenant’s legal fees.
The Two Pillars: Rent Control vs. Eviction Control
The biggest mistake San Francisco landlords make is confusing “Rent Control” with “Eviction Control.” They are two separate pillars of Chapter 37, and they apply to buildings differently.
Pillar 1: Rent Control (Price Caps)
If your building received its certificate of occupancy before June 13, 1979, it is generally subject to Rent Control. This means you are legally restricted to raising the rent by a tiny, Rent Board-approved percentage each year, tied to the Consumer Price Index. You cannot raise the rent to market rate until the tenant voluntarily vacates or is lawfully evicted, a concept protected by state law under the Costa-Hawkins Rental Housing Act.
Pillar 2: Eviction Control (Just Cause)
For decades, landlords thought that if they owned a newer building built after 1979, they were entirely exempt from Chapter 37. That is no longer true. In January 2020, San Francisco passed the “Haney Amendment.” This radically expanded the law so that Eviction Controls now apply to virtually all residential units in San Francisco, regardless of when they were built. Even if your building is exempt from rent caps, you still cannot evict a tenant simply because their lease expired. You must prove a “Just Cause.”
The 16 “Just Causes” for Eviction (And The Traps Within)
Under San Francisco Administrative Code Section 37.9, a landlord cannot recover possession of a rental unit unless they can prove one of 16 specific “Just Causes.” These are divided into two distinct categories.
1. “At-Fault” Evictions (The Tenant Did Something Wrong)
These evictions stem from a tenant’s breach, including non-payment of rent, severe nuisance, illegal use of the unit, or refusing lawful access to the landlord. However, landlords must beware of the 2022 Trapdoor, known as the 10-Day Cure. San Francisco recently passed an ordinance stating that before you can evict a tenant for most “at-fault” reasons, such as a lease violation or a nuisance, you must first give them a written warning and a 10-day opportunity to cure the violation. If you serve a standard 3-Day Notice to Quit without issuing this 10-day warning first, your eviction will be thrown out of court.
2. “No-Fault” Evictions (You Need the Property Back)
If the tenant has done nothing wrong, but you need your property back, you are stepping into the most highly litigated area of San Francisco real estate law. The two most common methods are Owner Move-Ins and the Ellis Act. For an Owner Move-In (OMI), you or a close relative must intend to move into the unit as your primary, principal residence for at least 36 continuous months. This is strictly limited to one OMI per building, and you must pay the displaced tenant a massive, legally mandated relocation fee. Alternatively, under the Ellis Act, you may wish to go out of the rental business entirely and remove all units from the market. This triggers severe long-term deed restrictions on your property and requires significant payouts to the tenants.
The San Francisco Unlawful Detainer Roadmap
When negotiations fail, property owners must navigate the San Francisco Superior Court to reclaim their property. A California Unlawful Detainer (eviction lawsuit) is a summary proceeding, meaning it moves incredibly fast, but it requires absolute perfection. Below is the standard procedural roadmap for a San Francisco eviction.
Step 1: Drafting and Serving the Termination Notice
Every eviction begins with a written notice. Depending on your Just Cause, this could be a 3-Day Notice to Pay Rent or Quit under California Code of Civil Procedure (CCP) Section 1161, a 15-Day Notice, or a 30/60-Day Notice. In San Francisco, state law is not enough. Your notice must explicitly state the specific Chapter 37 Just Cause for eviction, it must inform the tenant of their right to seek advice from the Rent Board, and it must include specific state-mandated disclosures regarding the Rent Relief Act.
Step 2: The San Francisco Rent Board Filing Mandate
This is the step where unrepresented landlords frequently fail. Serving the tenant is only half the battle. Under San Francisco Administrative Code Section 37.9(c), a landlord must file a copy of the termination notice, along with a proof of service, directly with the San Francisco Rent Board within 10 days of serving the tenant. Failure to file this document with the city renders your notice invalid and prevents you from moving forward with a lawsuit.
Step 3: Filing the Unlawful Detainer Complaint (UD-100)
Once the notice period expires and the tenant remains in the property, the legal lawsuit officially begins. You must draft and file a Summons (SUM-130) and an Unlawful Detainer Complaint (UD-100) at the San Francisco Superior Court, located at the Civic Center Courthouse. Under CCP Section 1166, the complaint must be perfectly verified, attach all underlying lease documents, and clearly plead how the notice was served. Once the court issues the Summons, a registered process server must physically serve these documents on the tenant.
Step 4: The Tenant’s Answer and Requesting a Trial
Under CCP Section 1167, a tenant has exactly five court days (excluding weekends and holidays) to respond to the lawsuit after being served. If the tenant fails to respond, you will file a Request for Entry of Default (CIV-100) to win the case automatically. However, in San Francisco, nearly all tenants file a formal Answer (UD-105) because of the city’s free legal representation programs. Once the Answer is filed, you must immediately file a Request to Set Case for Trial (UD-150) to force the court to schedule a trial date, which typically occurs within 20 days of the request.
Step 5: Securing the Writ and the Sheriff Lockout
If you win at trial, or win by default, the judge will issue a Judgment for Possession (UD-110). However, a judgment is just a piece of paper; you still cannot physically remove the tenant. You must take that judgment to the court clerk to have them issue a Writ of Execution (EJ-130) under CCP Section 715.010. You then deliver this Writ to the San Francisco County Sheriff’s Department, along with a Request for Sheriff to Serve Court Papers (SER-001) and Special Instructions for Writs (SER-011A). The Sheriff will post a final 5-day Notice to Vacate on the tenant’s door. If they do not leave, the Sheriff will return to physically perform the lockout and restore the property to you.
The Reality of Modern San Francisco Evictions
The roadmap above represents the easiest possible scenario—a straight line from a notice to a lockout. In modern San Francisco real estate litigation, that straight line almost never exists.
This roadmap is entirely barebones and does not even scratch the surface of the intricacies involved in a modern Unlawful Detainer case. Because tenants are heavily represented by skilled legal aid attorneys, your lawsuit will immediately be met with aggressive defensive tactics. Tenants will file Demurrers or Motions to Quash to challenge the technical validity of your complaint and stall the timeline. They will propound heavy, burdensome legal discovery that requires you to produce years of property records under tight deadlines. They may attempt to evade service of the initial lawsuit, forcing you to seek a court order to post the summons on the door, or they may even remove the case entirely to Federal Court to force a massive delay.
To deal with these aggressive intricacies, you cannot rely on forms printed from the internet. You need dedicated, strategic legal counsel fighting for your property rights.
