1500 12th Ave, San Francisco, CA 94122

The three-story, six-unit multi-family residential building at 1500 12th Avenue in the Inner Sunset, owned by Monika Pietraszek, was built in 1954 and has undergone several significant improvements over the years. Most recently, in September 2023, Unit #5 received a kitchen remodel, which included plumbing and electrical updates, at a cost of $30,000. The building completed a mandatory soft-story retrofit in 2016 (Tier 3) at a cost of $100,000, demonstrating compliance with seismic safety requirements.

Other notable maintenance work includes repairs to dry rot in the back stairs (2013), a new electrical service installation with seven meter sockets (2014), and window replacements from wood to vinyl dual glazed sliders (1997). The building has maintained regular upkeep with two recent plumbing permits in 2024 for water heater replacements, and historical records show multiple roofing projects were completed in 1990 and 2007. The property has experienced minimal serious issues, with only one paint-related housing complaint in 2011 that was promptly resolved.

A fire alarm system activation in 2012 was determined to be unintentional with no injuries reported. Recent 311 calls primarily concern street-related matters, including pavement defects, illegal postings, and illegal parking, though these are municipal rather than building-specific issues. The building's maintenance record shows consistent attention to necessary repairs and upgrades, with most recent improvements focused on individual unit modernization and essential systems like electrical and plumbing. The property has maintained its multi-family classification as an apartment building with 5-14 units throughout its history.
