Rent & eviction protection

Is 2109-2111 22Nd 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 1946

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 1946
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 2109-2111 22nd Street in Potrero Hill is a two-story, two-unit multi-family residential building constructed in 1946 and currently owned by Siu Maggie Hok Lam. The building has undergone several significant permit applications and maintenance work over the years, though with mixed outcomes. In 2017, there was an ambitious proposal (Permit #201708215424) for horizontal and vertical additions including new two-bedroom units and interior remodeling of existing efficiency dwellings, but this permit was ultimately cancelled. A completed plumbing improvement in 2015 involved replacing a failed water main, indicating maintenance attention to infrastructure needs.

More recent developments include multiple 311 calls in 2024 regarding street cleaning issues, primarily involving abandoned furniture, and several reports concerning parking violations including sidewalk parking and driveway blocking, though most of these cases were either not validated or the vehicles were no longer present when enforcement arrived. An interesting planning initiative was explored in 2023 involving a potential project to create four units of affordable housing by adding a three-story building behind the existing structure, though this appears to have been primarily an informational review. The building's history also shows minor maintenance work from 1989 involving window installation, but this permit has since expired. The property has experienced some recent challenges with street cleanliness and parking enforcement issues, though these appear to be more related to the immediate neighborhood rather than the building itself.

Risk rating

How 2109-2111 22Nd 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
36thpercentile

Out of 726 buildings in this neighborhood, 465 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Building age

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