Initial analysis

The 579 41st Avenue property in the Outer Richmond is a 4-story, 2-unit multi-family residential building constructed in 2002, owned by Chancey C and Dianne T Kong R. The building underwent significant construction work in 2001-2002, including the installation of a sprinkler system and the demolition of a previous structure, followed by the completion of a new building. In recent years, there have been two notable maintenance projects: in 2021, five property line windows were upgraded to meet fire safety requirements with 45-minute fire-rated glass and U-values less than 0.30, and in 2020, damaged siding on the south side of the building was repaired. A safety complaint was filed in March 2022 regarding construction practices, though this was not an active violation.

There have been recurring parking-related issues in the vicinity of the building, with multiple complaints between 2021 and 2024 regarding vehicles blocking driveways, illegal parking, and double parking. These incidents were generally addressed through citations or warnings by parking enforcement officers. While the building itself has maintained compliance with safety standards and building codes, it's worth noting that a false fire alarm incident was recorded, though it resulted in no civilian injuries. The property's record shows a pattern of regular maintenance and compliance with building regulations, with recent improvements focusing on safety features such as the property line windows.

Risk rating

How 579 41St 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
46th percentile

Out of 1040 buildings in this neighborhood, 562 are predicted to be safer.
