Initial analysis

The two-story, four-unit multi-family residential building at 1879 9th Avenue in the Inner Sunset, owned by the Lee Jim Chon Estate, was constructed in 1960 and has undergone several significant improvements and maintenance work over the years. Recent building improvements include a bathroom remodel filed in 2020 (cost: $14,500) and the completion of electrical upgrades with an underground service conversion in 2003 (150A meters). Historical maintenance records show roofing work was performed in 2011 (cost: $7,800), while earlier improvements included window installations in 1993 and a reroofing project in 1994. In 1984, there was a notable compliance project to address certain building code requirements.

The building has experienced two routine housing inspections that resulted in multiple violations requiring attention. The 2001 inspection identified fire safety issues including combustible storage, fire extinguisher maintenance, and gas meter information requirements, while the 2010 inspection revealed various concerns including weatherproofing, lead paint hazards, inadequate lighting, electrical issues, and the presence of removable cord wiring. All violations were subsequently abated, typically within approximately one to two months. The property also underwent significant work addressed under the City’s Housing Code requirements related to lead paint hazards, as documented in the 2010 inspection. More recent activities at the address have primarily involved parking-related issues, with multiple enforcement requests between 2019 and 2022, though these are external to the building's condition or maintenance concerns.

Risk rating

How 1879 9Th 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
38th percentile

Out of 1493 buildings in this neighborhood, 926 are predicted to be safer.
