242 24th Ave, San Francisco, CA 94121

The two-unit residential building at 242 24th Avenue, owned by Laura Lum, is a two-story structure built in 1922 located in the Lake --The Presidio neighborhood. The property underwent significant renovations and improvements between 2015-2019, including substantial first-floor expansions adding bedrooms, bathrooms, an office, and family room, along with new interior staircase connections. This renovation phase included various permits for plumbing (two bathrooms, laundry room), electrical (new lights, switches, receptacles), and building modifications, though there were some unauthorized work complaints regarding construction debris in December 2015 and an August 2016 complaint about a vacant lot.

The building's infrastructure was notably upgraded in 2009-2010 with electrical service replacement, and a central heating system was installed in 2015. Recent issues from 2021-2024 suggest ongoing maintenance challenges, particularly with sewer systems, as there were multiple sewer backup incidents reported through 311 calls in early 2022. The property has experienced recurring parking management issues, with documented cases of driveway blocking in 2021, 2023, and 2024, though these are not directly related to building conditions.

A preliminary inspection of the property indicated proper rear yard/open space access for both units. While there have been some neighborhood quality of life issues documented through 311 calls (such as graffiti and general cleaning requests), these appear to be street-level concerns rather than direct building-related issues. The most recent fire incident recorded was a smoke detector activation due to malfunction, with no civilian injuries reported.
