Initial analysis

The two-unit residential building at 1211-1213 20th Avenue in San Francisco's Central Sunset neighborhood has a documented history dating back to 1989 when it was constructed as part of a three-unit residential project. The property underwent significant safety improvements in 1996 with the installation of ground floor sprinklers and fire escape modifications, though these permits expired. A notable address assignment occurred in 2010 to officially designate 1213 20th Avenue as an additional address for the two-family dwelling.

Recent months have seen numerous incidents requiring municipal attention, with the majority relating to street and sidewalk cleanliness, particularly concerning garbage and debris. The property has experienced recurring issues with waste management, as evidenced by multiple reports between September 2022 and October 2024. Parking enforcement has also been active in the vicinity, with citations issued for illegal parking in July 2023 and March 2024. The most recent municipal interactions include handling of a encampment situation in November 2024, which was resolved with the subjects being advised to leave the area. The building's permit history suggests it has maintained compliance with required inspections, with final inspections obtained for work completed under earlier permits in 2009. The property is currently managed under the ownership of the "Jow Brenda Tom 2000 Tr" trust designation.

Risk rating

How 1211-1213 20Th Ave'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
