25-29 Adair St, San Francisco, CA 94103
The three-unit, three-story residential building at 25-29 Adair Street in the Inner Mission, owned by Gregory Gagnon, was constructed in 1911 and is classified as a Flats & Duplex building. The property has undergone several significant improvements over the years, including an electrical service upgrade to 175A with 4 meters completed in 2003, and a kitchen and bathroom remodel in 1984.
More recent history reveals some concerning safety issues, particularly regarding elevator operations - there have been multiple incidents recorded between 2023 and earlier years involving elevator problems, including victims needing removal from stalled elevators, with the most recent elevator-related incident occurring before 2023. The building experienced multiple fire department responses, including one documented fire code violation in June 2023, though all incidents recorded by the fire department generally resulted in no injuries or significant damage. The property has recently faced some maintenance and neighborhood interaction challenges, particularly in 2024, with multiple reports of garbage and debris issues (generally involving yard waste or overflowing city garbage cans) and several instances of driveway blocking that required parking enforcement intervention.
Historical records show some earlier modifications, including the removal of a wooden exterior ladder in 2009 per Board of Supervisors ordinance requirements. The building has undergone periodic safety inspections, with routine inspections in 2003 and 2008 showing no ongoing violations, though the most recent fire code violation from 2023 is worth noting. A planning record from 2023 indicates the property was involved in a Determination of Eligibility process related to the 490 South Van Ness Avenue Affordable Housing Development project.
