Understanding SF Rent Control: A Tenant's Guide

San Francisco's rent control law — officially the Residential Rent Stabilization and Arbitration Ordinance — is a powerful set of protections that most tenants don't fully understand until the moment they need them. This guide explains the basics: who's covered, what your landlord can and can't do, and where to turn for help.

Who Is Covered?

Rent control in SF applies to most residential units built before June 13, 1979. If you live in one of those units and have been there for more than one year, you have strong protections: your landlord cannot raise your rent above the annual allowable increase without Rent Board approval, and cannot evict you without a just cause.

Units built on or after June 13, 1979 are exempt from rent caps under the state Costa-Hawkins Rental Housing Act — but they may still be subject to SF's just cause eviction protections depending on when they were built. This is a critical distinction that many tenants miss: rent control (limiting increases) and just cause eviction protection are separate systems with different coverage rules.

The Annual Allowable Increase

Each year, the SF Rent Board sets an allowable increase percentage — typically 60% of the Consumer Price Index (CPI), capped at 7%. In recent years, the allowable increase has ranged from 0.7% to 2.3%. Your landlord may raise rent by this amount once per year, with proper notice: 30 days for increases under 10%, 90 days for larger increases.

Anything above the allowable increase requires a petition to the Rent Board, which the landlord must file and win. Common grounds for above-guideline increases include capital improvements to the building or increased operating expenses — but these are subject to scrutiny and approval.

Just Cause Evictions

Even if your lease has expired, a landlord covered by the Rent Ordinance cannot evict you without one of 16 legally recognized just causes. These fall into two categories: fault-based (non-payment of rent, lease violations, nuisance) and no-fault (owner move-in, Ellis Act withdrawal, demolition). No-fault evictions come with specific procedures and generally require relocation assistance.

If you receive an eviction notice, do not ignore it. You have a limited window to respond. Contact the SF Tenants Union, Bay Area Legal Aid, or the Tenderloin Housing Clinic immediately.

Banking Unused Increase Rights

A landlord who doesn't raise rent one year does not "lose" that increase — under most circumstances, they can bank it and apply it in a future year (subject to limits). This is a common surprise for tenants who have enjoyed years of stable rent and then suddenly face a large increase. Always check what the allowable increase is for your unit and whether your landlord is within the legal limit.

What to Do If Your Rights Are Violated

If your landlord raises your rent above the allowable amount without Rent Board approval, you can file a petition with the Rent Board — for free. The Rent Board has authority to roll back illegal increases and, in some cases, award damages. You can also file a complaint for illegal eviction attempts, harassment, or reduction in services.

The SF Rent Board offers free drop-in counseling at 25 Van Ness Ave. The SF Tenants Union at sftu.org maintains a 24-hour hotline and offers member counseling sessions. Bay Area Legal Aid (baylegal.org) provides free legal representation for income-eligible tenants facing eviction.

Your rental unit is more than an address — in SF, it's an asset. Understanding your rights is the first step to keeping it.
