Rent & eviction protection

Is 941-945 Jones 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 1909
2 or more units

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 1909
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 941-945 Jones Street property is a three-story, multi-family residential building constructed in 1909 and owned by Tyler Y & Helen L Woo Bypas. The building has undergone several significant improvements over its lifetime, including the installation of fire sprinkler systems in 1990, foundation raising work in July 1990, and the addition of vinyl windows in 2002. More recent maintenance includes a kitchen and bathroom remodel in 2021 (permit expired) and a street space permit issued in 2012. The building has been subject to regular housing inspections, with routine safety inspections recorded in 2019, 2016, and earlier years showing various compliance issues that were generally addressed, including security concerns about doors and ladders in 2010 and 2016.

The property has experienced some recent external concerns as evidenced by 311 calls in 2023 and 2024, including reports of encampments, excessive noise, and parking violations. While these issues occurred in the vicinity of the building, they relate more to the surrounding area than the building's internal conditions. The building's documented history shows a pattern of regular maintenance and prompt attention to compliance issues as they arise, with no recent active building violations on record. The most significant historical work included the installation of safety features such as fire sprinklers and subsequent structural and aesthetic improvements.

Risk rating

How 941-945 Jones 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
85thpercentile

Out of 448 buildings in this neighborhood, 67 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
