Initial analysis

The three-story multi-family residential building at 337-343 San Jose Ave, constructed in 1900, currently contains 6 apartments and is owned by SF Mission Properties LLC. The property has experienced several significant maintenance and safety issues over the past two decades, with the most pressing current concerns being three active violations from March 2023 related to peeling exterior paint, weatherproofing issues, and paint conditions that may pose lead hazard risks. Historical records show a recurring pattern of stairway-related problems, with violations and repairs documented in 2002, 2004, and 2010, including a 2010 violation requiring handrail installation in the rear stairway and repairs to damaged stairs. Other notable repairs include a 2004 reroofing project ($8,000), window replacements, and multiple interventions for dry rot issues, particularly a significant $15,000 repair to both front and rear walls in 2004.

The building has a documented history of moisture and ventilation problems, with a 2004 complaint about bathroom humidity and mold issues, and more recent 2023 concerns about weatherproofing. Historical maintenance records reveal various repairs to stairs, handrails, and structural elements, with stair-related work performed in 2003 ($8,500) and previously in 1989. While there have been some building violations that were properly addressed and abated, including a 2002 egress obstruction issue, the current active violations from 2023 suggest ongoing maintenance challenges. The most recent 311 calls from 2024 primarily concern exterior debris and furniture removal, though these are not directly related to building condition issues.

Risk rating

How 337-343 San Jose 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.

Out of 2380 buildings in this neighborhood, 1880 are predicted to be safer.
