835 45th Ave, San Francisco, CA 94121

The three-story multi-family residential building at 835 45th Avenue in the Outer Richmond, owned by Lun Keith Chi & Kwong Marga, is a two-unit flats/duplex structure built in 1934. The property has undergone several significant improvements over its lifetime, with the most substantial being a major renovation in 2001-2003 that included vertical and horizontal additions, interior modifications including stair removal, and extensive electrical upgrades (installation of 60 outlets, 40 light fixtures, and a 200-amp service).

More recent maintenance includes regular water heater replacements in 2019 and 2017. The building experienced two sewer-related incidents in July 2017 that required PUC Sewer Operations intervention, though both issues were resolved. The property's history also shows attention to infrastructure upgrades, including an attempted solar water heating installation in 1985 (permit cancelled) and various other permits from the 1980s.

In recent years, there have been multiple 311 calls primarily regarding parking violations and sidewalk issues between 2017 and 2022, with several reports of sidewalk parking violations involving specific vehicles (a BMW X3 and an Audi Q5) in 2020, as well as two general cleaning cases in 2022. The street space permit issued in 2003 suggests coordination with public infrastructure, though further details are not provided in the available records. While the building has required periodic maintenance and experienced some infrastructure challenges, particularly in 2017, records indicate that issues have generally been addressed through proper channels.
