Rent & eviction protection

Is 1169-1171 Bay St 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.

Built before 1979
Built 1924

Statewide backstop · AB 1482

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.

15+ years since occupancy
Built 1924
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

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.

Initial analysis

The two-unit residential building at 1169-1171 Bay Street in the Marina neighborhood is a two-story flats and duplex structure built in 1924, currently owned by the Chan Trust. The building's permit history shows a kitchen renovation in 2006 costing $6,500 that included new sinks, counters, and cabinets, along with associated electrical work (though one electrical permit was cancelled). A reroofing project was attempted in 1999, though the associated permit expired without record of completion. More recently, there was an incident in November 2024 involving a fallen tree that required attention from street and environmental services.

The property has experienced various maintenance and service issues in the surrounding area over the last decade. Notable recent incidents include a driveway blocking incident in May 2024, illegal postings in August 2023, and a street cleaning issue involving waste in December 2022. Historical records show previous concerns such as graffiti in March 2020 (which was postponed for resolution during shelter-in-place conditions), a driveway blocking incident in November 2020, and other routine municipal service requests. The building's maintenance record shows limited major work in recent years, with the last significant interior improvement occurring in 2006.

Risk rating

How 1169-1171 Bay St'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.

Neighborhood percentile
96thpercentile

Out of 988 buildings in this neighborhood, 40 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
