Board passes first reading of ordinance banning use of algorithmic rent‑setting tools

The San Francisco Board of Supervisors unanimously passed on first reading an ordinance July 30 that would amend the administrative code to prohibit the sale or use of algorithmic devices to set rents or manage occupancy levels for residential dwelling units in San Francisco.

Supervisor Mandelman, the sponsor, said the ordinance seeks to curb the use of third‑party revenue management software — notably tools marketed to large property owners and management companies — that can act as a de‑facto price‑setting platform. The sponsor described how some industry investigators and company employees characterize dominant services (citing a company called RealPage) as having consolidated a monopoly-like position in rental revenue management, which can result in higher rents and more units held vacant.

The sponsor framed the measure as a pro‑housing step intended to address a new mechanism for artificial price fixing that has emerged with the consolidation of ownership and the spread of predictive pricing software. The ordinance was described at committee and the clerk noted that the Department of Elections and the budget/analyst review concluded no economic impact analysis was required for the measure.

The board took the item "same house, same call" following committee recommendation and passed it unanimously on first reading. Further committee or second‑reading steps were indicated as the ordinance progresses.

Why it matters: The ordinance would be among the first local laws aiming to regulate algorithmic pricing practices in residential housing, addressing concerns about market concentration and automated tools that multiply an individual owner’s access to non‑public market data.

What’s next: The ordinance advances through the city's legislative process for additional readings and implementation detail.
