Rent & eviction protection

Is 1861 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 1960
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1960
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 2-story multi-family residential building at 1861 Chestnut Street, located in San Francisco's Marina neighborhood, was constructed in 1960 and contains 5 units. The property has undergone several significant maintenance updates over the years, including two roofing projects in November 2018 costing $55,500 and $11,520 respectively, and a window replacement project in 2005 that involved installing 11 wood composite windows, which cost $15,000. The building experienced multiple safety-related violations in 2000 and 2008, though all were successfully abated by August 2008. These violations included issues with fire safety (smoke detectors, fire extinguisher maintenance, and garage ventilation), egress obstruction, and self-closing exterior doors.

More recent history shows a routine safety inspection in 2016, and there were two similar complaints in August 2019 regarding unsafe painting practices involving scaffolding and netting. The building has been subject to various municipal services calls between 2021 and 2024, primarily related to street cleaning and maintenance issues, including graffiti removal and illegal postings. The most recent incident was a garbage and debris complaint in August 2024 that was resolved by Recology. While the building has undergone necessary maintenance and complied with violation corrections, the pattern of 311 calls in recent years suggests ongoing attention to exterior maintenance and public space management is required.

Risk rating

How 1861 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
33rdpercentile

Out of 988 buildings in this neighborhood, 662 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location
