197-199 Beaumont Ave, San Francisco, CA 94118

The two-unit residential building at 197-199 Beaumont Avenue in the Lone Mountain neighborhood, owned by Ted C & Devi Thadani Mackay, was constructed in 1941 as a two-story flats/duplex structure. The property has undergone several significant maintenance and improvement projects over the years, with the most recent being a reroofing project completed in October 2022 at a cost of $11,500.

Previous major works include a comprehensive window and door replacement project in 2010 valued at $23,500, replacing 12 windows with Marvin wood inserts and one door with a Therma-Tru door. The building's electrical system received substantial upgrades in 2004-2005, including the installation of a 200-amp underground service with three meters and panels, along with extensive wiring work including new receptacles and lighting for various rooms throughout the building. The property's maintenance history shows regular upkeep, particularly regarding roofing, with multiple reroofing projects documented in 1993, 1996, and 2003.

A notable incident occurred in March 2002 when a complaint was filed regarding potentially illegal in-law units and a fire hazard involving security bars, though this was abated within two months. More recent urban challenges in the area have included various 311 calls in 2024-2025, such as issues with graffiti, parking violations, and sidewalk defects, though these are primarily related to the surrounding neighborhood rather than the building itself. A malfunctioning alarm system was recorded as the only fire-related incident, with no civilian injuries reported.
