4031 Mission St, San Francisco, CA 94112

The two-unit residential building at 4031 Mission Street in Bernal Heights, owned by the Chauhan Family Trust, is a two-story flats and duplex structure built in 1948. The property's maintenance history includes several significant events, most notably an electrical system upgrade in 2003 involving an underground service conversion and a 240V main service upgrade with two meters, which was completed successfully.

A reroofing project was initiated in 1999 but the permit has since expired. Of particular concern is a building complaint filed in December 2000 regarding unauthorized construction of an in-law unit in the basement, with reported work hours from 8 AM to 9 PM, though this case is currently listed as not active. The surrounding area has experienced numerous municipal services calls over recent years, primarily between 2019-2022, with several reports of abandoned vehicles (seven incidents in total), all of which were resolved with vehicles being gone upon inspection.

There have also been multiple street cleaning incidents reported, including general cleaning needs and hazardous material removal (glass) in late 2020. The most recent service calls have been resolved, with some still showing as open or accepted, particularly regarding loose garbage as of May 2020. It is worth noting that while these external issues have been documented through 311 calls, they primarily relate to street conditions rather than the building's internal systems or maintenance.
