119-121 16th Ave, San Francisco, CA 94118

The property at 119-121 16th Avenue, located in the Lake-The Presidio neighborhood, is a two-unit multi-family residential building constructed in 1912 and currently owned by Qi Yan. The building has undergone several significant proposed developments in recent years, with the most substantial being a current filed permit from November 2022 seeking to add a story to the upper unit (119 16th Avenue) and create additional living space on the ground floor (121 16th Avenue), including adding three bedrooms and two bathrooms, a 13'-8" rear extension, and a new rear deck with spiral stairs.

Prior to this, in 2019, the property underwent a voluntary seismic retrofit (soft story) for $65,000 in compliance with San Francisco building code requirements, demonstrating attention to structural safety. In January 2022, a notable tenant buyout occurred for both units of the building, with $150,000 paid to four tenants ($75,000 per tenant) for vacancy. The property has experienced some maintenance issues, most recently in 2022 with a sidewalk defect involving an obstructive basketball hoop, though this was resolved through city enforcement.

Historical records show the building has gone through various proposed modifications, including attempts to create two ADUs in 2020 (though these permits were withdrawn), and some minor window upgrades in the 1990s. Earlier issues in 2000 regarding unauthorized construction in the garage area were addressed promptly and are no longer active complaints. The planning records indicate various stages of proposed development work, with the current permit representing the most substantial proposed modifications to date.
