Rent & eviction protection

Is 1001 Bosworth 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.

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.

Annual rent increase cap

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 property at 1001 Bosworth St is a two-family residential building located in Glen Park, constructed in 1928 and currently owned by Nicholas Fonti. The two-story flats/duplex building has undergone several significant modifications and faced multiple compliance issues over the years. Most recently, in November 2023, a violation was issued regarding sleeping area requirements, and there is an open sleeping area requirements violation recorded for 907-943 Bosworth St. In 2014, the building faced serious concerns with unauthorized modifications, including a change of garage use to a bedroom, removal of a required second means of egress, and construction of an unpermitted catwalk bridge, though these violations were subsequently abated.

The building has a history of maintenance and compliance challenges, particularly related to safety features and unauthorized modifications. In 2012, there was an incident involving carbon monoxide concerns and heating issues, while multiple building violations were recorded in 2012 regarding stairways, windows, and various systems. The property has undergone several legitimate improvements, including window replacements in 2005 and 2007, electrical and plumbing upgrades between 2008 and 2010, and stair repairs completed in 2012. Recent maintenance issues have primarily involved exterior concerns, as evidenced by multiple 311 calls in 2024 regarding garbage, debris, and landscaping maintenance. The building's fire safety systems have also undergone periodic inspections and corrections, with violations noted for alarm systems in 2010 and 2019, sprinkler/standpipe systems in 2017, and a sleeping area violation in 2023.

Risk rating

How 1001 Bosworth 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
