4787-4791 Mission St, San Francisco, CA 94112

The two-story, 14-unit multi-family residential building at 4787-4791 Mission St in the Excelsior neighborhood, owned by Altamir P & De Souza, has experienced several significant maintenance and safety issues over the past decade. Most recently, in 2023, the building received multiple fire safety violations related to blocked exits, exit maintenance, extinguishers, and alarm systems, all of which were documented between February and March 2023.

The property underwent substantial commercial improvements in 2016-2017, including the conversion from a market to a restaurant (Mama Mari's Taqueria) with associated electrical and plumbing work, though this period also saw some gas line repair issues, including a leak in 2018 and several gas line modifications in 2019. Previous building history reveals persistent fire safety concerns, with documented violations in 2005 and 2007 regarding exit signs, fire alarms, and extinguishers that were eventually abated.

The building experienced two sewage-related incidents in 2023-2024, and more recent complaints include parking enforcement issues and occasional sanitation matters. Historical records show several routine housing inspections between 1996 and 2014, with various violations noted regarding security, fire safety, and plumbing systems, most of which were resolved through correction orders. The property has maintained active commercial use throughout its history, with multiple permits for retail and restaurant operations, including the recent installation of a UL-300 hood and duct fire suppression system in 2019.
