Rent & eviction protection

Is 2056-2058 20Th 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 1974

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 1974
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 2056-2058 20th Street in Potrero Hill, owned by the Ann Parris 2001 Trust, was constructed in 1974 as a two-story flats and duplex structure. The property's maintenance records show two significant upgrades: the installation of 13 new windows in 2009, replacing aluminum units with vinyl ones featuring improved energy efficiency (U-value 0.34), and a roofing project from 1997, though this permit has since expired.

The building has experienced recurring sewer-related issues, with three documented incidents of sewage vent problems through a 4-inch opening between 2021 and 2022, suggesting potential ongoing infrastructure challenges in this area. Other reported incidents have primarily involved exterior and street-related concerns, including a defaced parking sign in 2021, glass hazards in 2016, and loose garbage in 2013, all of which were promptly addressed and resolved. A recent 311 call in 2023 regarding an abandoned vehicle in the vicinity was also resolved when parking enforcement arrived to find the vehicle had already left the area. While the building has received regular maintenance and upgrades over the years, the history of sewer issues warrants particular attention as the most significant pattern in the building's service history.

Risk rating

How 2056-2058 20Th 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
86thpercentile

Out of 726 buildings in this neighborhood, 102 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
