Initial analysis

This two-unit multi-family residential building at 351 Silver Avenue, owned by the Ng Family Trust, was constructed in 1917 and is located in San Francisco's Excelsior neighborhood. The property has undergone several significant improvements over the past decade, with the most substantial work occurring in 2011, when the front unit underwent a major remodel including floor plan reconfiguration, window replacements, and the installation of skylights, along with associated plumbing and electrical work totaling approximately $20,000. The building has received consistent attention to its infrastructure, including two reroofing projects in 2010 and 2014 costing $4,500 and $7,500 respectively, and the installation of a new furnace in 2011.

Of particular note is a period of concern regarding unauthorized unit modifications in 2007, when a housing inspection determined that an additional unit had been improperly added to the rear structure (351A) with unapproved wiring and plumbing. This violation was officially abated by August 2008. There were also several planning proposals in 2007-2008 for larger expansion projects, including a two-story addition and conversion of the first floor to parking, but these plans were ultimately withdrawn or cancelled. More recently, there has been a notable pattern of street and sidewalk cleaning issues in the vicinity of the property, with multiple reports of garbage and debris between October 2024 and January 2025, though these are external to the building itself. The only recorded fire-related incident was a routine medical assistance call with no civilian injuries reported.

Risk rating

How 351 Silver Ave'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.

Neighborhood percentile
