4587-4589 Mission St, San Francisco, CA 94112

The two-unit, 1906 mixed-use building at 4587-4589 Mission Street in the Excelsior neighborhood comprises a two-story structure with retail space, currently occupied by Double Shot Coffee, and residential units. In 2016-2017, the property underwent significant commercial renovations, converting a former personal services space into a limited restaurant with new seating, kitchen facilities, and ADA-compliant restroom facilities, with the project valued at over $112,000. This work included comprehensive plumbing and electrical upgrades, such as the installation of multiple sinks, floor drains, and new electrical fixtures. The building's infrastructure improvements are noteworthy, with historical records showing重要 structural upgrades to address unreinforced masonry walls completed in 1993, though several early-90s permit applications were either cancelled or expired.

A roof replacement was completed in 2009, and the building underwent a furnace replacement in 2016. Recent maintenance and safety issues have emerged, particularly regarding graffiti, with multiple incidents reported throughout 2024-2025, though some cases were resolved through abatement measures. A missing side sewer vent cover reported in September 2024 remains an open issue. The building has experienced three recorded gas-related incidents (two gas leaks and one carbon monoxide detector activation) between 2010 and 2023, though none resulted in civilian injuries.

The property has maintained compliance with health and safety regulations, as evidenced by its 2017 Health Permit approval for limited restaurant use in the neighborhood commercial district. Recent 311 calls primarily involve parking enforcement matters, with limited validation by responding officers, suggesting these may be related to street conditions rather than building-specific issues. The property has a documented history of modifications and improvements, with all significant recent work falling within legally permitted scope. While recent graffiti and plumbing maintenance issues warrant attention, they represent typical urban building challenges rather than systemic problems. The building's historical records show a pattern of responsible maintenance and upgrades, particularly with regard to structural integrity and seismic safety, through both completed and cancelled applications in the early 1990s period.
