Initial analysis

The three-unit residential building at 1374-1376 21st Avenue in San Francisco's Central Sunset neighborhood is a two-story flats and duplex structure built in 1926, currently owned by Andrew Fong and Betty Woo Cho. The building's maintenance record shows minimal documented work, with only one permitted reroofing project from 1996 on file, which is now expired. The property has undergone one routine housing inspection in 2002 that was completed on the same day and is no longer active.

The surrounding area experienced several quality-of-life issues between 2018-2024, with the most recent incidents primarily involving parking violations, including citations for sidewalk parking (most recently in August 2024) and an attempted response to a blocked driveway complaint in March 2024. The property is located in an area with recurring sanitation challenges, evidenced by five documented instances of human or animal waste requiring cleanup between March and November 2018. A pavement defect was reported and resolved in March 2012, and most recently, a housing inventory fee request was processed in November 2024. While the building's official record shows relatively few documented permits and inspections, it's worth noting that many of the recorded incidents (particularly from 2018) relate more to exterior street and sidewalk conditions rather than the building itself.

Risk rating

How 1374-1376 21St 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.
