Initial analysis

The two-story multi-family residential building located at 331-335 Taraval Street in the West Portal neighborhood, owned by John Y.C. and Eva L. Tang, has a documented history of several renovation projects and recent compliance issues. Built in 1940, this flat & store property contains three residential units and was originally built with commercial space, classified as a building with 4 units or less. The most recent significant renovation work includes interior improvements as of September 2023, involving vinyl floor replacement, interior painting, and cabinet installation, though this work has triggered an active building violation complaint for work allegedly performed without proper permit approvals. Prior to this, the building underwent re-roofing in 2017 (cost: $14,550), and multiple unit improvements throughout the 1980s and 1990s, including kitchen remodels in both the upper unit (1995) and kitchen/bath renovations (1989). A horizontal addition permit filed in 1998 is notably marked as expired.

The property has experienced various maintenance and infrastructure issues as documented through 311 calls between 2021 and 2024, including recent incidents in late 2024 involving sewage backup discharge and a streetlight issue. Other reports from 2023-2024 highlight concerns with sidewalk defects, a driveway blocking incident, and utility line issues. The only recorded fire incident was related to public service assistance with no civilian injuries reported. The building's violation status as of September 2023, regarding expired permits and associated monitoring fees, is of particular note, representing the most recent and potentially ongoing compliance issue with the property.

Risk rating

How 331-335 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.
