Rent & eviction protection

Is 121 Arkansas 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 1900
2 or more units

Property type
Multi-Family Residential

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 property at 121 Arkansas Street in Potrero Hill is a two-story, three-unit multi-family residential building constructed in 1900 and currently owned by Virginia Stangl. The building's maintenance history shows several roofing issues in 1996, with multiple permits issued in June of that year for reroofing projects and compliance with a HID report. During the same period, the property experienced significant maintenance problems, including roof leaks causing water damage to multiple units, dry rot in the stairwell, and garage door issues, all of which were documented in housing inspection complaints between March and June 1996. The building has a documented history of unauthorized unit concerns, with complaints filed in 2001 and 2011 regarding illegal units and over-occupancy, the most recent complaint taking over a year to resolve. There were also complaints in 2001 about unpermitted work.

More recent history shows consistent street and sidewalk cleaning needs near the property, with multiple 311 calls for loose garbage between 2020 and 2023, though these appear to be external to the building itself and likely relate to general neighborhood upkeep. Parking enforcement was requested twice in 2020-2021 for illegal parking in the area, and the most recent incident related to park rules violation was recorded in June 2024. While these external issues don't directly reflect on the building's current condition, they indicate ongoing maintenance and compliance monitoring in the vicinity. The most concerning issues appear to be from the 1996 period, with no significant building-related complaints or violations documented in the past decade, suggesting possible resolution of those historical maintenance issues.

Risk rating

How 121 Arkansas 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
45thpercentile

Out of 726 buildings in this neighborhood, 399 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.

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.
