Initial analysis

The 4-unit, 2-story multi-family residential building at 3121 Taraval Street in the Outer Parkside neighborhood, owned by Lui Chee Heung Chan & Lai M, has experienced several significant issues since its construction in 1951. The most pressing current concerns involve multiple active violations related to lead paint hazards dating from January 2017, including damaged paint requiring remediation, routine inspection access, and necessary interior maintenance. These violations, along with others filed in 2017, triggered multiple Notice of Violations (NOVs) between April 2017 and August 2018, with a director hearing scheduled for January 2019. The building also shows multiple safety concerns that remain unresolved, including issues with fire escape drop ladders, fire extinguisher requirements, carbon monoxide and smoke alarm compliance, and structural maintenance requirements, all documented in the 2017 violations.

The property's maintenance history reveals some infrastructure work, including an underground electrical service conversion completed in 2006 and a reroofing project from 1996, though the 1993 garage modification into a store room/playroom permit has since expired. Additional housing enforcement activity includes a 2002 routine inspection and a 2017 complaint about a possible illegal unit in the garage. Recent external issues have been relatively minor, with a parking enforcement incident in October 2023 and a sewer vent cover replacement in 2021. The building's documented history suggests ongoing maintenance and safety compliance challenges, particularly regarding lead paint hazards and general building upkeep requirements.

Risk rating

How 3121 Taraval 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.
