4022 23rd St, San Francisco, CA 94114

The two-unit multi-family residential building at 4022 23rd Street in Noe Valley, owned by the Alan J Lavine Revocable Trust, has a documented history dating back to its construction in 1890. The property's maintenance record shows significant infrastructure care, including a complete reroofing project in 2007 costing $9,800, the construction of a 40-foot concrete retaining wall at the rear in 2004 costing $18,000, and termite repairs completed in 1991.

The building experienced notable plumbing issues in December 2021, with four separate sewer backup incidents reported within a few days, followed by additional plumbing work in late 2007 involving a 3-foot sewer line replacement from cast to clay material at the building's base. Recent events at the property have primarily involved external matters, with two documented instances of driveway blocking in 2023 - one resulting in a citation for a BMW in August, and an unresolvable complaint about a Volkswagen in September.

Earlier infrastructure concerns included a hazardous materials incident involving glass in 2016, an abandoned motorcycle complaint in 2016, and a street lighting issue in 2015. The building's maintenance and repair history suggests regular upkeep of structural elements, though the 2021 sewer incidents may indicate some challenges with the building's waste management systems.
