Initial analysis

This two-story, four-unit multi-family residential building located at 3813-3817 Anza St in San Francisco's Central Richmond neighborhood was built in 1948 and is currently owned by Yan Kam Yu. The property has experienced several significant maintenance and safety issues over the past few years, with the most recent concerns arising in early 2023 when water leakage and mold problems were reported, leading to permits for various plumbing and electrical repairs including floor repair, fixtures replacement, and electrical fixture replacement. Between 2017-2019, the building faced multiple violations and complaints including rodent infestation, lead paint hazards, and gas service restoration issues. A serious incident occurred in January 2019 when carbon monoxide alarms were reportedly not installed, resulting in nine tenants becoming sick and two requiring hospitalization, though this complaint has since been marked as not active.

The building has undergone several repair and maintenance projects to address various compliance issues, including the installation of wall heaters, dryer vent modifications, and water heater updates between 2017-2019. There have been multiple instances of unauthorized work reported, including a December 2019 complaint about unpermitted remodeling in Unit 3 involving kitchen and bathroom modifications and furnace removal. Various building system upgrades have been implemented over the years, including electrical and plumbing improvements, though some permits have subsequently expired. The property has also faced environmental concerns, with reports of asbestos in pipes and a mold problem that remains active as of early 2018. While many historical violations have been abated, there are several recurring issues such as moisture problems and unauthorized modifications that have persisted through the years.

Risk rating

How 3813-3817 Anza St'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.
