Rent & eviction protection

Is 2541-2543 Chestnut 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 1939

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.

Built 1939
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

This two-unit residential building, constructed in 1939 and located at 2541-2543 Chestnut Street in the Marina district, is owned by Carmen L & Alys V Zell and classified as a Flats & Duplex property. The building has undergone several significant maintenance and improvement projects over the past 20 years, with the most recent work being the installation of a new 40-gallon water heater in June 2023. Important plumbing upgrades include a sewer line replacement in May 2020, bathroom remodeling in 2011 (including drain and water pipe repairs), and comprehensive plumbing work in 2008 involving the replacement of hot and cold water pipes, kitchen sink, and shower faucet. The electrical system received attention in 2011 with the installation of a dedicated circuit and GFI outlet in the bathroom.

The property has experienced some recurring issues with parking violations, particularly in 2024, with multiple cases of driveway blocking reported through the 311 system, resulting in several citations being issued. In terms of infrastructure maintenance, there have been historical records of various improvements, including window installation in 2003 and reroofing work in 1995. The building's plumbing system has required ongoing attention, with documented repairs to shower drains and bathroom facilities in 2013, and the handling of a sewage backup issue in May 2023. While most maintenance work appears to have been properly completed, some older permits from the 1990s and early 2000s show as expired in the current records. The property has also had some landscaping and tree maintenance needs addressed, as evidenced by 2023 work orders.

Risk rating

How 2541-2543 Chestnut 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
70thpercentile

Out of 988 buildings in this neighborhood, 296 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
