Rent & eviction protection

Is 619-621 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 1907

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 1907
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 619-621 Chestnut Street property is a 2-story, 4-unit multi-family residential building constructed in 1907 in San Francisco's North Beach neighborhood, currently owned by the Ng Kee Fung Revocable Trust. The building has undergone several maintenance and compliance issues over the past two decades. Most notably, in June 2023, there were reports of severely peeling paint on the rear of the building, indicating ongoing maintenance challenges. A series of building violations were documented in 2005 requiring attention to safety features such as smoke detectors, staircase repairs, and gas utility shutoff tools, though these were ultimately abated by July 2005. The property has consistent records of routine inspections, with the most recent inspection from December 2015 still listed as active.

The building's fire safety systems have required attention, with two complaints about alarm systems (in 2014 and 2021) that were promptly corrected. While there have been several fire department responses to the building, including false alarms and smoke detector activations, none resulted in injuries or significant damage. The property has faced challenges with exterior maintenance, particularly regarding paint condition, with violations noted in 2009 regarding peeling paint and potential lead hazards. Recent 311 calls from 2024 indicate issues with street cleaning in the vicinity, though these are external to the building itself and primarily relate to public space maintenance.

Risk rating

How 619-621 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
35thpercentile

Out of 362 buildings in this neighborhood, 235 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
