Rent & eviction protection

Is 1641-1643 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 before 1979
Built 1924
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 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 three-unit multi-family residential building at 1641-1643 Chestnut Street in the Marina neighborhood, owned by Sandra J Sherman Benjamin 2, has undergone extensive renovations and improvements since its construction in 1924. The property is currently experiencing substantial ongoing updates, with major works permitted in 2024 including bathroom remodels on the second and third floors ($50,000), significant ground floor renovations including kitchen remodel, bathroom relocation, additional bedroom and laundry room installation ($178,200), and associated plumbing and electrical upgrades. A complete kitchen remodel was previously completed in 2023 ($36,000), and the building received new roofing in 2008 ($7,380) and wood decay repairs at the tradesman's entrance in 2001 ($1,200). The electrical system has seen substantial modernization efforts, including a significant rewiring project that expired in December 2023 covering multiple areas of the ground floor.

The building's maintenance and safety record is generally positive, with only one fire complaint regarding alarm systems in 2014 that was determined to have no merit. The property has had recurring issues with vehicles blocking the driveway, with multiple citations issued between 2021 and 2024, though not all reported incidents were validated by enforcement officers. Recent maintenance activities have focused on upgrading bathroom facilities throughout the building, with multiple permits issued in 2024 for bathroom remodeling and shower pan replacement across different units. The most recent permits, issued in September 2024, confirm continuing investment in property improvements with no significant violations or safety concerns on record.

Risk rating

How 1641-1643 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
63rdpercentile

Out of 988 buildings in this neighborhood, 366 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
