S.F. Admin. Code ch. 37 § 37.11A
Civil Actions (San Francisco Rent Ordinance)
Operative Text
(a) Whenever a landlord charges a tenant a rent which exceeds the limitations set forth
in this Chapter, retaliates against a tenant for the exercise of any rights under this Chapter, or
attempts to prevent a tenant from acquiring any rights under this Chapter 37, the tenant may
institute a civil proceeding for injunctive relief and/or money damages, and in cases where the
landlord has charged an excessive rent in violation of Section 37.9B(a), injunctive relief and/or
money damages of not less than three times the amount of excess rent collected; provided,
however, that any monetary award for rent overpayments resulting from a rent increase which is
null and void pursuant to section 37.3(b)(5) shall be limited to a refund of rent overpayments
made during the three-year period preceding the month of filing of the action, plus the period
between the month of filing and the date of the court's order. In any case, calculation of rent
overpayments and re-setting of the lawful base rent shall be based on a determination of the
validity of all rent increases imposed since April 1, 1982, in accordance with Sections 37.3(b)(5)
and 37.3(a)(2) above.
(b) Any organization with tax exempt status under 26 United States Code Section
501(c)(3) or 501(c)(4) that has a primary mission of protecting the rights of tenants in San
Francisco may bring a civil action for injunctive relief and/or damages against a landlord who has
wrongfully endeavored to recover, or has recovered, possession of a rental unit in violation of
Section 37.9(a)(8), or who has collected excess rent in violation of Section 37.9B(a). Such action
shall be filed within three years after an affected tenant knew, or through the exercise of
reasonable diligence should have known, of the facts constituting the violation. However, before
bringing any action under this Section 37.11A(b), the organization shall first provide 30 days’
written notice of its intent to initiate civil proceedings by serving a draft complaint on the City
Attorney’s Office and on any known address(es) of the affected tenant(s), and may bring the
action under this Section 37.11A(b) only if neither the City Attorney’s Office nor the tenant(s)
have initiated civil proceedings by the end of the 30 day period. Any monetary award for rent
overpayments shall be for two times any excess amounts of rent charged, as well as any other
sums reasonably expended to investigate and prosecute the claim, and shall be limited to the
three-year period preceding the month of filing of the action, plus the period between the month
of filing and the date of the court’s order.
(c) The prevailing party in any civil action brought under this section 37.11A shall be
entitled to recover reasonable attorneys' fees and costs. The remedy available under this
Section 37.11A shall be in addition to any other existing remedies which may be available.Section 37.11A of San Francisco Administrative Code Chapter 37 establishes civil lawsuit rights when a landlord charges rent above the allowable limits, retaliates against a tenant for exercising rights under the Chapter, or tries to block a tenant from gaining those rights. A tenant may sue for injunctive relief and money damages, and in certain excess-rent situations the damages floor is three times the amount of rent overcharged. Qualified nonprofit tenant-rights organizations may also bring civil actions under § 37.11A(b) in specific circumstances, subject to a 30-day notice requirement and a three-year filing window. The prevailing party in any such action is entitled to recover reasonable attorneys' fees and costs, and these remedies stack on top of any other remedies that may already exist.
Plain English — not legal advice.
Under § 37.11A, operators who charge rent above the Chapter 37 limits, retaliate against tenants, or interfere with tenants' rights under the Ordinance expose themselves to civil liability that can include injunctive relief, money damages, and mandatory payment of the prevailing party's attorneys' fees. In cases involving violations of Section 37.9B(a), damages can be set at no less than three times the excess rent collected, making compliance with allowable rent ceilings a significant financial consideration. Compliant operators generally maintain accurate records of all rent increases dating back to April 1, 1982, since § 37.11A requires courts to evaluate the validity of every increase from that date when calculating overpayments and resetting the lawful base rent.

Section 37.11A gives San Francisco tenants the right to file a civil lawsuit when a landlord charges rent above the Chapter 37 limits, retaliates for exercising rights under the Ordinance, or attempts to prevent a tenant from acquiring those rights. Depending on the nature of the violation, available remedies can include injunctive relief, money damages, and recovery of attorneys' fees if the tenant prevails — with treble damages available in certain excess-rent situations under Section 37.9B(a). Tenants who believe their rights under § 37.11A have been violated may consider consulting a tenant-rights organization, reaching out to the San Francisco Rent Board, or speaking with a housing attorney to understand the range of enforcement paths available to them.
