San Francisco weighs rent fee disclosures to curb hidden costs

A base rent that looks manageable can turn into a much larger monthly bill once amenity charges, pest-control fees, application costs and move-in expenses are added in. San Francisco Supervisor Bilal Mahmood is now pushing a proposal meant to expose those hidden costs before tenants sign a lease.

The measure, called the No Hidden Rent Act, would require rental listings to show a Total Estimated Cost alongside base rent and to itemize recurring monthly charges. Lease agreements would also have to put the total estimated monthly cost on the first page, while application and screening fees would need to be disclosed upfront. City officials say tenants could end leases without penalty if landlords fail to follow the disclosure rules.

Mahmood announced the plan on May 29, 2026, and the legislation is being developed with the San Francisco City Attorney’s Office, the San Francisco Rent Board and tenant advocacy groups. The idea is less about creating new housing than forcing clearer pricing in a city where renters often have to decide quickly in a competitive market.

The timing reflects how tight the market has become. Zumper said in late May that San Francisco’s one-bedroom median rent crossed $4,000 for the first time in city history, and it put the city at more than 21 percent annual rent growth, the fastest in the nation. Other trackers continue to rank San Francisco among the country’s most expensive rental markets, with one-bedroom medians hovering in the high $3,000s to about $4,000 depending on methodology.

That pressure lands in a city of 826,079 residents, according to the U.S. Census Bureau’s July 1, 2025 estimate, and it arrives alongside already limited rent protections. The San Francisco Rent Board says allowable increases for covered units are 1.6 percent from March 1, 2026 through February 28, 2027. State law under California’s Tenant Protection Act of 2019, or AB 1482, also limits annual increases to 5 percent plus local CPI or 10 percent, whichever is lower, and requires just-cause termination protections.

San Francisco’s proposal also fits a wider national crackdown on rental fee disclosure. In December 2025, Greystar agreed to a $24 million settlement with the Federal Trade Commission and the State of Colorado over allegedly deceptive rental advertising and mandatory fees. In March, the FTC opened a public comment process on rental housing fee practices, signaling more pressure on landlords to show the real monthly price up front.

For San Francisco tenants, the practical question is simple: whether the No Hidden Rent Act would change landlord behavior, or just make the fine print easier to read. In a market where a few extra charges can knock a household out of contention, that distinction could decide how much transparency actually matters.
