Rent & eviction protection

Is 2120 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 1928

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

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.

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-story, seven-unit multi-family residential building at 2120 Chestnut Street in the Marina District, owned by Bosco Family Investors Lp, was constructed in 1928 and has undergone several significant safety upgrades in recent years. The property completed mandatory seismic retrofit work in March 2020, with records showing separate permits for both commercial and residential sections of the building, costing a total of $41,334. In 2023, the building received substantial fire safety upgrades, including the installation of a new fire alarm system with low-frequency sounders in sleeping areas to meet current fire code requirements, at a cost of over $33,500. The building has a history of fire alarm system-related incidents, with multiple false alarms and system malfunctions recorded between 2011 and 2024, including a recent fire complaint in April 2024 that was found to have no merit.

The building's maintenance history shows regular upkeep, including a 400-amp electrical service upgrade in 2021, reroofing work in 2011, and recent exterior improvements such as awning replacement in 2015. A notable violation was recorded in March 2023 regarding failure to complete all associated work under the Mandatory Soft Story Program, though this appears to have been resolved by July 2024 with the issuance of the Certificate of Final Completion (CFC). The property has experienced periodic maintenance issues typical of its age, including historical violations in 2003 related to fire escape drop ladders and directional signs, though these were promptly addressed. Recent 311 calls in the area have mostly concerned sidewalk access and street cleaning issues, typical of urban neighborhoods, with the most recent being resolved complaints about scooters blocking sidewalks in January 2025.

Risk rating

How 2120 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
23rdpercentile

Out of 988 buildings in this neighborhood, 761 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

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

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

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
