3879 22nd St, San Francisco, CA 94114

The two-story, four-unit multi-family residential building at 3879 22nd Street in Noe Valley, owned by Paul and Kendall Heaney, has undergone several significant improvements since its construction in 1925. Most notably, between 2023 and 2016, the building has seen consistent window upgrades, with two recent projects in 2023 replacing windows in Units 1 and 3, following a similar pattern of window replacements in previous years (2016, 2006).

These upgrades demonstrate ongoing efforts to maintain energy efficiency, as all replaced windows meet modern U-factor standards. The building's infrastructure has received attention over the years, including a complete electrical upgrade in 2004 with a comprehensive 200-amp service and multiple circuits, a plumbing system update in 2016, and a reroofing project in 1991, though the latter permit has expired. The property has maintained good compliance with housing regulations, with routine apartment inspections in 2001 and 2007 showing no active violations.

While there have been two 311 calls related to the property - a tree maintenance issue in 2024 and a sidewalk defect investigation in 2015 - neither directly related to the building's safety or maintenance. The building appears well-managed, with all recent permits marked as completed and proper attention given to both unit-specific and common area improvements. The consistent pattern of window upgrades, in particular, suggests regular investment in maintaining and improving the property's residential quality and energy efficiency.
