Rent & eviction protection

Is 120-122 Coso Ave 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 1900

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 1900
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 two-unit residential building at 120-122 Coso Avenue in Bernal Heights is a two-story structure built in 1900, currently owned by Drew Tamsen. The building's documented history reveals several maintenance and compliance matters spanning multiple years. In 2021, significant roofing work was completed at a cost of $14,360, involving the installation of a three-ply modified bitumen system on the back flat roof. That same year, a formal determination was made regarding the building's legal two-unit, two-story classification based on city records and site inspection. Prior to these improvements, there were some concerning issues on record, including a 2014 complaint about uneven stairs creating trip hazards, and a 2010 incident regarding an unauthorized side addition, though the latter was promptly addressed the same day.

The property's more recent history (2019-2025) has primarily involved external factors affecting the vicinity rather than direct building concerns. There have been multiple reports of vehicles blocking the driveway between 2019 and 2025, with varying degrees of enforcement response. Other incidents have included noise complaints from a major event venue, a graffiti report on ATT property, a collapsed sidewalk concern (which could not be verified by inspection), and a hazardous materials report involving glass on the street. The building's structural integrity appears to have been actively maintained, as evidenced by the documented roofing work, and there haven't been any recent building complaints regarding the structure itself. Most recent incidents have been exterior matters such as street parking issues, sidewalk maintenance, and temporary urban disturbances rather than problems with the building's systems or structure.

Risk rating

How 120-122 Coso Ave'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
80thpercentile

Out of 1276 buildings in this neighborhood, 255 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.

Neighborhood location

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

Building age

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
