451-455 Duboce Ave, San Francisco, CA 94117

The three-story multi-family residential building at 451-455 Duboce Avenue, owned by Robert D. Sr & Cather Gallot, was constructed in 1900 and contains three units.

The building's maintenance history shows recurring attention to dry rot issues, particularly in the back stairs, with multiple repairs documented between 1992 and 1995. More recently, the building underwent mechanical upgrades in 2021, including the installation of a new gas furnace and associated ventilation work, with proper permits obtained and completed. The property has faced several building violations over the years, with the most recent active complaints dating from May 2016, primarily related to interior surfaces including paint conditions, fire safety features, and building weatherproofing.

Historical violations from 2000 indicated lead paint hazards, though these were marked as abated in 2001. The building's exterior maintenance has been a recurring focus, with multiple inspection records noting issues such as peeling paint. Recent 311 calls from late 2024 have primarily concerned parking enforcement matters, with multiple citations issued for driveway blocking, though these are external to the building's condition and maintenance history.
