Is 255-257 27Th Ave rent-controlled?
San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.
Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.
California Tenant Protection Act of 2019
Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.
AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

The two-unit residential building located at 255-257 27th Avenue in Sea Cliff is a two-story flats and duplex structure built in 1923, currently owned by the Leung/lau Family Trust. The building has undergone at least one significant structural improvement in recent years, with a completed reroofing project costing $16,300 in 2012. More pressing concerns have emerged in recent years regarding both the property and its surroundings. Between April and July 2023, multiple reports were filed concerning a tree's established lean and insufficient clearance from the building and sidewalk, which required intervention from the Department of Public Works and Arborists. The tree-related inspections completed in July 2023 documented concerns about both building and sidewalk clearance.

How 255-257 27Th Ave's risk score is calculated
We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.
What the score means for you
Lower risk — safer than most nearby
DBI rarely finds violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
Out of 20 buildings in this neighborhood, 3 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
