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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
87th percentile

Out of 726 buildings in this neighborhood, 94 are predicted to be safer.
