4735 Mission St, San Francisco, CA 94112

The three-story mixed-use building at 4735 Mission Street, constructed in 2003, comprises two residential units above a ground-floor commercial space, with ownership registered under Chen Yun & Jian Yan. The building's construction was completed following a significant February 2001 permit for adding two stories to the existing single-story commercial structure, valued at $450,000, which was supported by electrical upgrades including a 3-phase 400-amp underground service installation with four meters in January 2003.

Since its completion, the property has undergone several maintenance and modification works, including a $22,000 reroofing project in December 2018. Recent concerns regarding resident safety have emerged, particularly in mid-2024, with an open investigation into blocked common area exits that resulted in fire violations for storage in pathways and blocked roof exit access, though these violations were subsequently abated. The building has experienced recurring maintenance issues, including a sewage backup in October 2023 and multiple reports of general cleaning needs on the surrounding property.

Vandalism has been a concern, with multiple graffiti incidents reported on or near the building in 2024. The property's history includes several early 1990s commercial modifications, including kitchen hood installations and partition wall alterations, before its conversion to its current configuration. The building has undergone fire safety inspections and modifications over the years, with records indicating the installation of a fire system in the kitchen hood in 1994 and various fire safety improvements throughout its history.
