29 Coso Ave, San Francisco, CA 94110

The two-unit residential building at 29 Coso Ave in Bernal Heights is a two-story flats and duplex structure built in 1906, currently owned by the Day Garson-Darmet Family Trust. The building's maintenance history shows several significant structural and safety improvements over the decades.

In 1988-1989, critical safety work was completed, including repair and replacement of the front stairs and landing, as well as ceiling support reinforcement with 4x4 beams. More recently, in 2014, the property underwent a gas line replacement, demonstrating attention to infrastructure maintenance, though there remains an outstanding expired permit from 1998 for reroofing work that may warrant verification of completion status.

The property has experienced three relevant street-level incidents in the vicinity of the building over the past two years, though these are related to public infrastructure rather than the building itself. Two cases of overflowing city garbage cans were reported and resolved in 2022 and 2023, and there was one instance of human or animal waste that was addressed and resolved by the Department of Public Works in February 2022. While these exterior issues were promptly addressed by city services, they reflect conditions in the immediate neighborhood rather than the building's internal maintenance or safety.
