4427-4429 19th St, San Francisco, CA 94114

The two-unit residential building at 4427-4429 19th Street, owned by Louise Vasquez, is a two-story flats and duplex structure built in 1900 in the Eureka Valley/Dolores Heights neighborhood. The building has undergone several significant maintenance and improvement projects over the past two decades, with the most recent work in 2016 including a complete reroofing project costing $8,000 and the installation of vinyl siding on the back walls for $4,000.

A notable historical compliance issue occurred in 2000-2001 when a third unauthorized unit was discovered, resulting in a violation for unapproved alterations and life safety hazards, though this was abated by November 2001 through the removal of an unauthorized stove and other unauthorized modifications. Recent maintenance concerns include ongoing issues with tree roots damaging the sidewalk, as documented in two open complaints from 2021 and 2022, and a collapsed sidewalk noted in an open complaint from 2021.

The building's compliance history shows attention to structural elements, including a 2009 project to replace a retaining wall at the rear property line, though this permit is listed as expired. The property has experienced various urban challenges typical of the neighborhood, including parking issues (both illegal postings and vehicle blocking complaints), tree maintenance needs, and noise complaints, all of which have been addressed through various municipal channels. The most recent building-related incident was a property maintenance issue in late 2024 involving illegal postings, though this was resolved quickly.
