Initial analysis

The 4-unit apartment building at 330 Hamilton St in Portola, constructed in 1963 and owned by Lew Gar Kong Saw Associatio, has experienced several significant maintenance and safety issues over the past two decades, with particular attention needed to ongoing water-related problems. Most recently, in 2024-2025, there have been multiple permits and repair work involving apartments #2 and #3, including wall repairs behind rain gutters, stucco removal, and window replacement work totaling approximately $6,500. Notably, there are active complaints from 2024 regarding water intrusion and mold issues, as well as concerns about scaffolding and a neighbor's vehicle maintenance affecting the property. Historical records show persistent problems with water leaks and mold, particularly around windows, with complaints filed in 2010, 2011, and 2012. The building faced a notable cluster of violations in 2006 that required remediation of various issues including garage door problems, electrical outlets, kitchen appliances, mold, egress obstruction, water damage, and safety systems, all of which were abated by January 2007.

The property has undergone various improvements over the years, including window upgrades in 2000 and deck repairs in 2006, and has completed several compliance-related permits for window replacements and safety upgrades between 2011 and 2018. Recent permits (2024-2025) indicate ongoing maintenance work, though persistent water-related issues remain a concern. The building's management has generally responded to violations and complaints, as evidenced by the completion of multiple building permits, though some historical permits from 2011-2012 related to window replacements are marked as expired rather than completed. The property has several documented 311 calls for street cleaning and maintenance issues between 2013 and 2024, though these are primarily related to public areas rather than the building itself.

Risk rating

How 330 Hamilton 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.
