Initial analysis

The White Family Living Trust owns this three-unit, three-story multi-family residential building located at 437-441 Webster Street in Hayes Valley, which was constructed in 1908. The property has experienced several maintenance and safety concerns in recent years, most notably with persistent heating issues, as documented in 2022 complaints about no heat in the main building and damaged windows. There are also current active concerns regarding lead paint safety and general maintenance from September 2022. The building underwent significant water damage repairs in 2021 costing nearly $100,000, and more recently, in March 2024, windows on the south side were replaced and heaters were installed, indicating ongoing infrastructure upgrades.

Historical records show various improvements and compliance work dating back to the 1980s, including the installation of kitchen appliances in 1989, replacement of rear stairs and retaining wall in 1996, and conversion of garbage areas to storage in 2007-2008. The property faced multiple violations between 2007-2010 related to fire safety, building maintenance, and encroachments, though these were ultimately abated. Recent activity in early 2025 shows multiple reports of encampments and a noise complaint in the vicinity, though these are external to the building itself. The building's electrical system received upgrades in 2003 with the installation of a new service for four meters, and recent maintenance suggests ongoing attention to building systems and safety compliance.

Risk rating

How 437-441 Webster 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.
