Initial analysis

The property at 1331 46th Avenue in the Outer Sunset is a two-story, four-unit multi-family residential building built in 1916 and currently owned by the Debra J Tyler Living Trust. The building's history shows several significant events, most notably three major building code violations in 2005-2008 regarding unauthorized construction and safety concerns. In 2005, a window was reportedly added to the first level at the property line without proper permits, followed by a 2008 violation concerning unpermitted unit conversions, which cited numerous safety hazards including questionable electrical and plumbing work, lack of proper smoke detectors, and potential fire safety violations. The building underwent multiple repairs and upgrades between 2004-2009, including electrical system repairs following fire damage, installation of new stairways and handrails, and various plumbing improvements including a 2020 water heater replacement for units A and B.

Recent records from 2022-2024 show ongoing maintenance issues, particularly with the building's sewer system, which experienced back-ups in both 2022 and most recently in November 2023. There have also been several parking enforcement issues near the property, with multiple reports of sidewalk parking violations between 2022 and 2024. The building's maintenance history includes various electrical and lighting improvements, with significant work completed in 2004-2006 addressing fire damage repairs, stairway improvements, and kitchen electrical installations. While many historical violations appear to have been addressed and abated by 2011, the property continues to experience periodic maintenance challenges, particularly with its plumbing systems.

Risk rating

How 1331 46Th 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
