Initial analysis

The three-unit multi-family residential building at 3758-3762 20th Street in Mission Dolores, owned by the Survivors Trust-Freidenberg Family, was constructed in 1909 and features three stories with flats and duplex configurations. The property has undergone several significant improvements over the years, with the most recent work occurring in 2022 when two damaged windows were replaced, and five additional windows were upgraded to double-hung wood windows at a cost of $9,000. A notable infrastructure upgrade occurred in 2015 with the complete replacement of the sewer line and house trap, and in 2010, a comprehensive bathroom remodeling project was completed across all three units, including electrical work for lighting, switches, receptacles, and fans. The building has experienced minimal serious issues, with only one set of violations recorded in 2002 related to fire safety and gas meter instructions, all of which were resolved within several months. The property has maintained regular upkeep with historical records showing reroofing in 1997 and building code compliance updates in 1987.

Recent activity around the property has primarily involved street-level issues rather than building concerns, including multiple parking enforcement calls for driveway blocking in 2024, and several calls for graffiti removal, cleaning, and waste management services between 2020 and 2024. The building's maintenance history shows regular attention to necessary repairs and upgrades, with no active building violations or complaints as of the most recent records. The property's systems, including plumbing and electrical infrastructure, have received appropriate updates and maintenance, with the most recent major work focusing on window replacements and general upkeep.

Risk rating

How 3758-3762 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.
