Main finding
Rent control increased stability for covered tenants, while affected landlords converted or redeveloped buildings and reduced the regulated rental supply.
Covered tenants were 10–20% more likely to remain; treated rental supply fell 15%

Main finding
Covered tenants were 10–20% more likely to remain; treated rental supply fell 15%
Most important limitation
The often-cited 5.1% citywide rent increase is a structural-model estimate, not the direct reduced-form rent coefficient, and the policy is specific to San Francisco.
From the publication
The paper separately traces covered tenants staying longer and renters leaving treated buildings.
