San Francisco, California: habitability & repair laws

The Board can lower the rent and nothing more: in its own words, it has no authority to compel the landlord to restore the service, and can only order a rent reduction for the loss of it. Housing services are defined broadly enough to carry habitability complaints into the petition — repairs, maintenance, heat, water, light and quiet enjoyment all count — and the city's tenant harassment section adds a bad-faith failure to repair, or to follow repair, containment and remediation protocols for mold, lead paint, asbestos, dust and noise, as a ground of its own. The reduction reaches back no more than one year before the petition is filed unless the tenant proves extraordinary circumstances or long-term notice, and three limits hold the money down: no more than the amount requested for each item, no more than the monthly base rent in total, and nothing at all for out-of-pocket costs, personal injury or property damage, which belong in court. The petition is generally limited to units first occupied before June 13, 1979, so much of the city's newer housing cannot use it, and the repairs themselves are enforced by the Department of Building Inspection rather than by the Rent Board.

San Francisco habitability law at a glance

How fast

Three clocks shape this remedy, and the first is the one that decides how much money is on the table. No rent decrease is allowed for any period more than one year before the petition is filed, unless the tenant shows one of three things: extraordinary circumstances; long-term notice, spoken or written, from the tenant or another reliable source about a decrease inside the unit, or constructive notice of a condition that already existed when the tenancy began; or actual notice, constructive notice, or both, about a decrease in a common area. That limit and its three exceptions are in the Rent Board's own Rules and Regulations at § 10.10(c), a rule last amended on August 20, 1996 — not in the ordinance, and not in unwritten Board practice. The interior and common-area exceptions must each be proved by a preponderance of the evidence, and the common-area exception is the easier of the two: constructive notice on its own will do, and there is no requirement that the condition date from the start of the tenancy. The second clock is the ordinary hearing. It is held within 45 days of the filing of the petition, and the level of housing services may not be decreased at all between filing and the close of the hearing (§ 37.8(e)(1)). An appeal to the Board is due within 15 calendar days of the mailing of the findings of fact; the Board takes appeals in its discretion and three members must vote to hear one; and anyone aggrieved by a Board decision has 90 calendar days from the mailing to seek judicial review (§ 37.8(f)(1), (f)(3), (f)(9)). The third clock is the expedited track under Rules § 11.25, open to a tenant petition alleging decreased housing services with a past value of $1,000 or less as of the filing date, and separately to a petition alleging failure to repair and maintain where the tenant attaches documentary evidence that the unrepaired conditions violate applicable health or safety codes. Staff decide within 7 calendar days whether the case is suitable, the hearing is scheduled within 21 calendar days of the application, and the written order follows within 10 calendar days of the hearing, with any payment or refund ordered within no more than 45 calendar days. The speed is paid for: an expedited order carries no written findings of fact and no record of the hearing, it is stayed for 15 calendar days, an objection filed within that window dissolves it automatically, and an order nobody objects to is final — not appealable to the Board and not subject to judicial review.

What the tenant can do

A tenant may petition the Rent Board for a reduction of base rent where the landlord, without a corresponding reduction in rent, has substantially decreased housing services, has failed to provide a housing service reasonably expected under the circumstances, or has failed to provide a service verifiably promised before the tenancy began (Rules and Regulations § 10.10(a)). The ordinance is what makes that work: a reduction in housing services without a matching reduction in rent counts as a rent increase (§ 37.2(q)), and the right to ask for an arbitration hearing on a substantial decrease in services, or on a failure to perform ordinary repair and maintenance required by state or local law, sits in § 37.8(b)(2)(A). Habitability reaches the petition through the definition: housing services include repairs, replacement, maintenance, painting, light, heat, water, elevator service, laundry, janitor service, refuse removal and quiet enjoyment of the premises (§ 37.2(g)). The burden of proof is on the tenant, who must establish seven things under § 10.10 — that the item was a housing service; that it was reasonably expected or provided at the start of the tenancy, verifiably promised beforehand, or added later for additional rent; that the landlord or manager decreased, removed or stopped providing it; that the landlord or manager had actual or constructive notice; that the service was not restored within a reasonable time after that notice; that the decrease was substantial; and that the landlord did not cut the base rent by a reasonable amount to match. The petition goes in on the Board's own form, and the examples the form itself gives of a decreased housing service are a broken refrigerator, lack of heat and mold. A second route runs through the city's tenant harassment section, which makes a bad-faith interruption of housing services required by contract or by housing, health or safety law, a bad-faith failure to perform required repairs and maintenance, and a bad-faith failure to exercise due diligence in completing repairs or to follow appropriate industry repair, containment or remediation protocols for noise, dust, lead paint, mold or asbestos each a substantial and significant decrease in services for which a tenant may petition (§ 37.10B(a)(1) through (a)(3), (c)(1)). That route is narrower than the section reads on the page. In Larson v. City and County of San Francisco (2011) the Court of Appeal held that the Board may not order rent reductions under subdivisions (a)(4) through (a)(15), that subdivision (a)(7) is invalid in its entirety, and that the attorney fee provision at (c)(6) is invalid in its entirety; only the housing services, repairs and repair-protocol grounds at (a)(1) through (a)(3) still support a Rent Board rent reduction. The hard limit on the whole track is what the petition cannot do: the Rent Board has no authority to compel a landlord to restore a service, and can only order a rent reduction for the loss of it. Repairs are enforced by a different city department. Two rules govern how this remedy sits beside the others. Relief granted under § 10.10 precludes relief under § 10.11 except where the failure to repair and maintain is itself a substantial decrease in housing services, and the same subsection says expressly that it does not limit any civil remedies otherwise available to a tenant or a landlord, so filing here does not give up a court claim. Section 10.11 is a different remedy with its own clock: within 60 days of receiving a notice of rent increase, a tenant may petition to have that increase denied because the landlord failed to perform requested repair, replacement or maintenance required by state and local law. It blocks the increase; it does not cut the rent the tenant is already paying.

What the tenant gets

What the tenant gets is money, and only money. An administrative law judge who grants a decrease must state when the decrease commenced, the value of the decrease and the nature of the service, and must state the amount to which the rent can be increased when, and if, the service is restored (Rules § 11.24(b)) — the decision puts a price on restoration rather than requiring it. On the ordinance side the judge may order payment or refund of the cumulative amount within 15 days of the mailing of the findings of fact, or order that amount added to or offset against future rents, with any such order stayed if the losing side appeals in time (§ 37.8(e)(7)). Three limits, all stated on the Board's own petition form, cap the figure. The judge cannot reduce the rent for an item by more than the amount requested for that item in the petition. The judge cannot order a total monthly reduction larger than the tenant's monthly base rent. And the Rent Board cannot award money for out-of-pocket expenses, personal injury or property damage — those claims belong in court, and § 10.10(f) leaves them intact. Where a rent increase is denied instead, for failure to perform ordinary maintenance and repair, the judge must specifically enumerate the repairs that are necessary and the amount to which the rent can be increased once they are completed (Rules § 11.24(c)). That is a list and a price, not an order to do the work.

Who enforces it and how

The Rent Board runs this remedy through its administrative law judges, and nothing starts without a tenant: the track is petition-driven, there is no proactive inspection behind it, and the ordinance puts the burden of proof on the tenant. Appeals go to the Board itself, which hears them in its discretion and only where three members vote to hear the appeal, and a party aggrieved by a Board decision has 90 calendar days from the mailing to go to court. The Board's powers are enumerated in § 37.6 and run to conducting hearings, adopting rules, hiring staff and administrative law judges, publishing the annual allowable increase and reporting — they include no power to order, compel or enforce repairs, and no injunctive power of any kind. Code enforcement is the Department of Building Inspection's function: its Housing Inspection Services investigates complaints about substandard living conditions, assigns a district housing inspector by address, and is the office that can require the work to be done. The practical division for a tenant is money at the Rent Board and repairs at Building Inspection; neither office does the other's job, and a tenant with a habitability problem and a rent claim often needs both.

What housing is covered

This petition belongs to tenants of rent-controlled units. The Rent Board's own statement is that it is not available for most tenants in units built after June 13, 1979 or in affordable housing units such as Section 8, and the petition form warns on its first page that where the building was constructed after June 13, 1979 the unit is probably exempt from the ordinance's rent increase limitations and the Board cannot process the petition. The date itself comes from § 37.3(g)(1): the owner of a newly constructed unit that first received a certificate of occupancy after June 13, 1979, or that the Board has certified as substantially rehabilitated, may set the initial and all later rents, subject to four listed exceptions. Units whose rents are controlled or regulated by a government agency fall outside the ordinance's definition of rental units except in listed situations, and the general arbitration provisions where this petition lives are not among the sections extended to tenant-based rental assistance units — which is the statutory reason the Board says the petition is not available for subsidized housing. Hotel, motel, inn, rooming house and boarding house accommodations come under the ordinance only once a tenant has occupied them for 32 continuous days or more. Dwelling units in qualifying nonprofit cooperatives, and accommodations in hospitals, convents, extended care and licensed residential care facilities and in school and college dormitories, are excluded outright. A tenant who pays rent to a master tenant files a subtenant petition instead of this one. Tenants of units in areas designated under the city's earlier rental assistance program before July 1, 1977 use a different track. And for units that only came under rent control later, no decrease allowed under § 10.10 may take effect earlier than December 22, 1994.

How this fits with California law

California's implied warranty of habitability and its statutory repair-and-deduct, rent-withholding and retaliation rules apply in San Francisco exactly as they do everywhere else in the state, and nothing in this local track takes them away — the rule that governs it says in terms that it does not limit any civil remedy otherwise available to a tenant or a landlord. What San Francisco adds is administrative rather than judicial: a tenant in the city's rent-controlled housing stock can go to the Rent Board and have the rent itself cut for the loss of a housing service, which state law nowhere provides, while the repair order that state law does contemplate has to come from somewhere else.

Leading court decisions

• Larson v. City and County of San Francisco, 192 Cal.App.4th 1263 (Court of Appeal of California, First Appellate District, Division One, 2011) — The judicial powers clause of the California Constitution bars the Rent Board from ordering rent reductions under the tenant harassment section's subdivisions (a)(4) through (a)(15), because the losses those subdivisions describe are general damages and awarding them is a judicial function. The facial challenge fails as to subdivisions (a)(1), (a)(2) and (a)(3) — bad-faith failure to provide housing services, failure to perform repairs and maintenance, and failure to exercise due diligence in completing repairs or to follow repair, containment or remediation protocols for noise, dust, lead paint, mold and asbestos — because those grounds ordinarily produce a quantifiable pecuniary loss, and so a rent reduction that is restitutive rather than compensatory. The court also held subdivision (a)(7), on continued buyout offers after a written opt-out, invalid in its entirety, and held the mandatory tenant-side attorney fee provision at (c)(6) invalid in its entirety because a city cannot add a fee mandate to the state unlawful detainer statutes. Read the opinion.

Notes and caveats

• The Rent Board sets a price, it does not order the work — This is the single most important thing to know before filing. The Rent Board's own service page says it "has no authority to compel the landlord to restore the service, but can only order a rent reduction for the loss of the housing service." The structure of the law says the same three more times: the ordinance's remedial subsection gives the administrative law judge a money menu only — payment, refund, or an amount offset against future rents; the Board's enumerated powers contain no repair power and no injunctive power; and the rules tell the judge to state the amount the rent can go back up to "when, and if, the service is restored," which prices restoration rather than requiring it. A tenant who needs the condition fixed files with the Department of Building Inspection; a tenant who wants the rent cut for living without it files here. Most people with a serious habitability problem need both.
• This page does not add a local list of what must be fixed — San Francisco's rent-reduction track states no habitability standards of its own. It runs on the Rent Ordinance's definition of housing services, and on the state and local housing, health and safety laws that definition points to — so what must be fixed is answered by California's rules and by the city's building and housing codes, not by the rules governing this petition. That is why this page changes only what a tenant can do, how fast, and what the tenant gets.
• There is no heat figure here — Nothing in the Rent Ordinance or in the Rent Board's rules on this remedy sets a temperature, a heating season or a heating standard. "Lack of heat" appears only as one of the examples the Board's own petition form gives of a decreased housing service. San Francisco's minimum heating requirements live in the city's Housing Code, which the Department of Building Inspection enforces, and this page states no figure from it.
• What the rule actually names, and what it does not — Section 10.10 contains no list of habitability conditions: the words habitability, code violation, mold and water intrusion appear nowhere in it. Mold appears once in the whole Rent Ordinance, in the tenant harassment section's repair-protocol ground, and once more as an example on the Board's form, alongside a broken refrigerator and lack of heat. Summaries that present the rule as if it enumerated mold, water intrusion or uncorrected code violations are describing something the text does not say. The code-violation hook that does exist attaches to the separate failure-to-repair petition, where documentary evidence of a health or safety code violation opens the expedited track.
• The one-year limit is not a filing deadline — It limits how far back the rent reduction reaches, not the tenant's right to file. A decrease that began three years ago and continues today can still be petitioned; without one of the three exceptions, the money simply starts one year before the filing date. Filing sooner is therefore worth real money, and the exceptions turn on notice, so telling the landlord in writing and keeping a copy is what preserves the longer reach.
• A three-year window exists, for something else — The ordinance allows refunds of rent overpayments caused by rent increases that are null and void for up to the three-year period before the month the petition was filed, plus the time from filing to decision. That window belongs to unlawful rent increases. It is not the lookback for a decrease in housing services, which is the one year in the rules, and the two should not be run together.
• Section 10.11 will not cut the rent — The companion rule is often described as a repair remedy, and it is not one. It lets a tenant who has just received a notice of rent increase petition, within 60 days of receiving it, to have that increase denied because requested repairs or maintenance were not performed. It blocks a raise; it does not reduce the rent already being paid. The reduction remedy is section 10.10, and relief under 10.10 precludes relief under 10.11 unless the failure to repair and maintain was itself a substantial decrease in services.
• Eviction protection is not rent protection — San Francisco extended just-cause eviction protection to units built after June 13, 1979 and to substantially rehabilitated units in 2020. That did not extend rent coverage, and this petition follows rent coverage. A tenant in a 1990s building may well have the city's eviction protections and still be told the Board cannot process a decrease-in-services petition.
• Why the coverage date is 1979, and what would move it — The date is not a local policy choice the city could revisit on its own. State law, at Civil Code section 1954.52, is what freezes it, and San Francisco has already legislated what happens if that ever changes: section 37.3(g)(1)(E), added in 2024, says that if the state provision is amended or repealed the June 13, 1979 date immediately ceases to apply and moves forward by operation of law to the latest date state law allows, up to and including June 13, 1994 — with no further vote at City Hall. As things stand the state provision is unchanged since a 2004 amendment that took effect on January 1, 2005, so the June 13, 1979 line still governs and roughly fifteen years of additional housing stock stays outside this remedy.
• A note in the city's code about the harassment grounds — Alongside the Court of Appeal holdings, San Francisco's published code carries a note recording that a final decision of the San Francisco Superior Court held the phrase "with ulterior motive or without honest intent" in that section unenforceable. Read with the surviving grounds, the operative requirement for a harassment-based rent reduction is bad faith.
• Currency of the rules behind this page — The decrease-in-services rule has not been amended since August 20, 1996, and the companion repair rule not since March 7, 1989; the expedited hearing rule dates from June 20, 1992. The Board's own complete list of amendments to its rules runs to January 13, 2026 and shows no later change to any of them. On the ordinance side, the petition and remedy section was last amended effective December 10, 2018 and the harassment section effective January 20, 2020, while the definitions and rent limitation sections this page relies on were last amended effective February 8, 2026.
