Initial analysis

The multi-family residential building at 1395 40th Avenue in the Outer Sunset, owned by Wei-chen & Fengying Chen Fm, has experienced several significant maintenance and safety issues over its history. The two-story, four-unit building, constructed in 1954, has undergone various repairs and upgrades, including a $4,500 window replacement project in 2006 that upgraded aluminum windows to vinyl in units 1, 2, and 3, and individual window repairs in unit 4. The building faced a series of concerning moisture-related problems in early 2006, including mold issues in multiple units and a roof leak that resulted in flooding and appliance damage, following which extensive repairs were undertaken including window replacements and hardwood floor repairs. The property has a history of fire safety concerns, particularly evident in 2001-2002 when violations were recorded for fire escape-related issues and missing smoke enclosure door closers, though these were all abated by February 2002. Additional maintenance work included a $6,000 reroofing project and electrical system upgrades in 2002, which brought the building's electrical infrastructure up to code with a new 200-amp main service and five electric meter sockets and panels.

More recent history shows the building has remained active in terms of maintenance and compliance, with routine inspections occurring regularly, including a 2011 inspection that had no active violations. The property is currently facing ongoing parking-related issues, as evidenced by multiple 311 calls for parking violations near the property between September and December 2024, though these are not directly related to building conditions or safety. The building's maintenance history suggests a pattern of prompt response to violations and necessary repairs, with all documented violations being officially abated. The most recent building-related issues have primarily centered around infrastructure upgrades and routine maintenance, indicating improved overall building condition but also highlighting some ongoing challenges with exterior drainage and weatherproofing systems.

Risk rating

How 1395 40Th 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.
