316-318 Maple St, San Francisco, CA 94118

The 316-318 Maple Street property is a 3-unit, 2-story multi-family residential building located in Presidio Heights, constructed in 1907. The building has undergone significant modernizations and improvements, most notably in 2012, including comprehensive renovations of all bathrooms and kitchens (~$75,000), electrical rewiring of all units, installation of gas fireplaces, foundation work, and plumbing upgrades including new water service and sewer pipes (~$24,000).

More recently, in 2022, the building received fire safety upgrades including the installation of low-frequency sounders in living areas and bedrooms, along with an upgrade to the fire alarm system to comply with current codes (~$16,800). The property's history includes an important conversion in 2007 from a 5-unit to a 3-unit configuration, though documentation shows this permit was cancelled. There were several routine safety inspections conducted in the early 2000s, with some violations noted in 2004 regarding smoke detectors, fire extinguishers, and emergency exiting, though these were promptly abated by July 2004.

The building underwent substantial improvements to its safety systems and infrastructure in 2012, including fire alarm system upgrades, complete electrical rewiring of all units, and various plumbing improvements. A notable complaint was filed in February 2012 regarding unpermitted work being conducted while the building was vacant, though this was addressed by March 2012. Recent records from 2024 show multiple parking enforcement calls regarding driveway blocking, with several citations issued, though this is not directly related to the building's condition or safety systems.
