226 12th Ave, San Francisco, CA 94118

The three-unit multi-family residential building at 226 12th Avenue in the Inner Richmond district is a 2-story flats and duplex structure built in 1881, currently owned by Lew Yuen Gum Trustee-surviv. The property has undergone several maintenance and improvement projects over the years, most notably a recent window replacement project completed in October 2024, involving the installation of 12 fiberglass windows of the same size and style on the street-facing facade, with a cost of $7,000. An earlier roofing project from 1996 is noted, though its permit has since expired.

The building's maintenance record shows two routine housing inspections - one in 2000 and another in 2009 - both of which were quickly resolved on the same day they were filed. A series of four 311 calls have been logged for the property's vicinity between 2016 and 2021, including some street maintenance issues (pavement defect), street cleaning needs (loose garbage), and graffiti incidents, all of which were resolved through appropriate city departments. A sewage backup issue was reported and resolved in June 2017, and some illegal dumping occurred in January 2017.

The property has experienced three fire alarm incidents between 2017 and 2020, though none resulted in actual fires or civilian injuries - including a carbon monoxide detector activation, a smoke detector activation with no fire, and a false alarm. The most recent building improvements, including the comprehensive window replacement, suggest ongoing investment in property maintenance, while the relatively few building complaints and their quick resolution suggest generally proactive property management. The record shows no significant pattern of serious maintenance issues or safety concerns, though the age of the building and its historical complaints history indicates typical urban residential challenges have occurred and been resolved over time.
