1419-1421 16th Ave, San Francisco, CA 94122

The property at 1419-1421 16th Avenue is a two-unit, three-story multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1923 and currently owned by the Quen Mei Chen Revocable Trust, this building underwent significant renovations between 2005 and 2008. The most substantial improvement was a major addition in 2006 that constructed a third floor with two new bedrooms, kitchen, and living room, converting it into the second unit and adding parking spaces.

This work was accompanied by comprehensive updates including the legalization of a downstairs office and laundry room, installation of a new fire sprinkler system on the top floor, and extensive electrical and plumbing improvements including 200-amp overhead service with three meters, five bathroom remodels, and two kitchen updates. The building's renovation period also addressed safety and modern living requirements, with the installation of 14 fire sprinkler heads, new furnaces, and various bathroom and kitchen improvements, all completed between 2005 and 2008. Earlier infrastructure work included rear yard retaining wall replacement (1996) and reroofing (1994).

Since the completion of these major improvements, the building's record shows minimal issues, with only two parking-related complaints in 2019 and 2024, both of which were resolved without incident. The property has a closed planning application from the period proposing additional vertical and horizontal extensions which was withdrawn, suggesting that not all proposed changes were implemented. The extensive renovation history and compliance with modern safety standards indicate a well-maintained property, though prospective tenants should verify the current status of any previously proposed improvements that may not have been completed.
