409-411 34th Ave, San Francisco, CA 94121

The two-unit, two-story residential building at 409-411 34th Avenue in San Francisco's Outer Richmond neighborhood, owned by Li Jun Chao & Chen Sabrina, was constructed in 1948 and has undergone several significant renovations and faced various challenges over the years. The most notable recent improvement occurred in 2017, when the property underwent comprehensive upgrading including kitchen remodels, bathroom construction, electrical service upgrade to 200 amps, complete rewiring, and installation of new fixtures, with a reported cost of $30,000.

This followed a period of serious maintenance issues in 2015 when multiple violations were documented, including problems with weatherproofing, interior surfaces, and safety features like smoke detectors, though these were all officially abated by February 2016. A complaint about construction without proper permits and associated noise in April 2017 was recorded but subsequently marked as not active. The building's maintenance history includes older improvements such as aluminum window installations in 1986, and a reroofing project in 1996, though these permits have since expired.

More recent service calls to the property have primarily concerned external issues like missed trash collections and pavement defects, with the most recent incidents occurring in 2023-2024. The building's recorded violations and complaints, particularly those from late 2015, suggest there was previously a period of significant physical maintenance issues, including problems with flooring, windows, walls, ceilings, and paint, along with concerns about lead paint hazards. However, these issues appear to have been addressed through the comprehensive renovation work completed in 2017, which included substantial upgrades to both units of the building.
