1451-1453 Thomas Ave, San Francisco, CA 94124

The property at 1451-1453 Thomas Ave in the Bayview neighborhood is a two-unit, two-story multi-family residential building constructed in 1910 and currently owned by the Estate of Michael L Brown. The building has experienced several significant issues over the past two decades, with the most concerning recent incidents occurring in 2017, when there were complaints of extensive mold, flooding, and possible illegal unit modifications. These issues follow a pattern of violations and repairs dating back to 2001, when the property faced multiple violations regarding an unauthorized habitable shed unit, which was subsequently reverted to storage use.

The building underwent some improvements in 2015, including electrical system upgrades with the installation of 2 - 100a meter main services, and repairs to dry rot on the back deck. However, there have been persistent maintenance and safety concerns, including multiple building violations in 2015 regarding water damage, damaged interior surfaces, mold, and electrical issues. The property has also had various infrastructure matters recently, with multiple 311 calls in late 2024 regarding tree maintenance issues, garbage concerns, and sidewalk defects, indicating ongoing maintenance needs.

A fire incident regarding electrical wiring was recorded, though no civilian injuries were reported. While the building has undergone some repairs and improvements over the years, the persistent pattern of violations and maintenance issues, particularly regarding moisture damage and unauthorized modifications, suggests ongoing challenges with building upkeep and regulatory compliance. Recent 311 calls indicate continued attention needed for property maintenance, particularly regarding exterior and infrastructure elements. The most recent building permits show some structural upkeep continues to be addressed, though the pattern of past violations suggests careful monitoring of building conditions would be prudent.
