What this means for a renter at this address on 2026-01-02.

Rent increases

No rule in the supplied law covers this.

Eviction protection

Applies. A landlord of a unit covered by the Rent Ordinance may evict only for one of 17 listed just causes, and that cause must be the dominant motive. Expiration of a lease or a change in ownership is not just cause. (S.F. Admin. Code ch. 37, § 37.9(a))

Security deposit

Applies. A landlord cannot demand or receive security (deposit, fee or charge) above one month's rent, in addition to first month's rent. Small landlords (natural persons or all-natural-person LLCs owning no more than two properties with four units total) may charge up to two months' rent, but not to service members. (Cal. Civ. Code § 1950.5)

Applies. Landlords must pay interest on tenant security deposits at 4.2% for March 1, 2026 through February 28, 2027. (S.F. Admin. Code ch. 49, § 49.2)

Application fees

Applies. A landlord may charge an application screening fee of no more than $30 per applicant (adjusted for CPI since 1998), and never more than actual out-of-pocket costs and time spent. No fee may be charged if no unit is available or will be soon, and the landlord must give an itemized receipt and follow first-come screening or refund rules. (Cal. Civ. Code § 1950.6)

Tenant screening

Applies. Landlords may not discriminate against applicants or tenants because of their source of income, including Section 8 vouchers and other government subsidies. Where a government rent subsidy applies, income standards must be based on the portion of rent the tenant pays, and applicants with credit history screening must be allowed to offer alternative evidence of ability to pay. Landlords may still ask about the level or source of income. (Cal. Gov. Code § 12955)

Rent-pricing software

Applies. It is unlawful to use or distribute a common pricing algorithm as part of a contract, combination or conspiracy to restrain trade, or to coerce another person to adopt prices or commercial terms recommended by such an algorithm. A common pricing algorithm is software or other methodology used by two or more persons that uses competitor data to recommend or influence a price. (Cal. Bus. & Prof. Code § 16729 (added by Stats. 2025, ch. 338, A.B. 325))

Applies. Landlords and others may not sell or use algorithmic devices, such as software that analyzes nonpublic competitor rental data, to set rents or manage occupancy levels for residential units in San Francisco. A tenant or the City Attorney can bring a civil action over violations. (S.F. Rent Ordinance § 37.10C (S.F. Admin. Code ch. 37))
