Initial analysis

The property at 379-381 4th Avenue in the Inner Richmond is a two-unit, two-story multi-family residential building constructed in 1900 and currently owned by Chen She Ji. The building has experienced several significant maintenance and safety issues over the past decade, with the most concerning cluster of violations occurring in late 2019. On November 22, 2019, multiple violations were documented, including rodent infestation, broken windows, door hardware problems, heating system malfunctions, lack of handrails, missing smoke detectors and carbon monoxide alarms, damaged walls, and more - all of which were subsequently addressed and officially abated by November 28, 2023. During this period, there were also complaints regarding heating issues, including a 2013 report of inadequate heating in multiple rooms, and a 2009 complaint about significant plumbing and water issues.

The building's recent maintenance history includes a plumbing permit issued in August 2020 for the replacement of a direct vent wall furnace, suggesting an effort to address the previous heating system problems. There have been two documented periods of vacancy - first in 2020, when the building was reported to have open doors, feces, trash, and squatters, and again in 2021 - though both situations were eventually resolved. More recent concerns have primarily involved exterior maintenance and waste management, with multiple 311 calls in 2022-2024 regarding garbage, debris, and waste receptacle management. The most recent issues appear to be less severe and primarily related to waste management rather than building condition or habitability concerns. The property has undergone various inspections and received multiple permits, indicating some level of ongoing maintenance and compliance with regulatory requirements, though the history suggests there were significant habitability concerns that required attention over the past several years.

Risk rating

How 379-381 4Th 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.
