625-627 Central Ave, San Francisco, CA 94117

625 Central Avenue is a two-unit residential building located in Park North, constructed in 1916 and classified as a flats/duplex structure. The property has undergone significant recent improvements, most notably the legalization of an additional ground-floor unit (627A) in 2021, which included installing fire safety systems, 1-hour fire separation, and updating building systems to meet modern codes.

2023-2024 improvements have focused on comprehensive modernization, including the installation of a fire sprinkler monitoring system ($12,686), complete bathroom renovations, kitchen cabinet replacements, and various system upgrades such as the installation of two 50-gallon electric heat pump water heaters, a wall-mounted Mitsubishi ductless heat pump system, and two forced air furnace replacements. The sprinkler system installation and associated plumbing work has been a major focus, with multiple permits issued and completed between 2023-2024, totaling over $50,000 in related costs. The building's systems have been extensively upgraded in recent years, with electrical improvements including new wiring, unit-specific electrical work, and the most recent sprinkler monitoring system installation.

Historical maintenance records show prior work in 2002 (stucco repair) and street space permits in 2008 and 2014. The property has experienced some neighborhood maintenance issues typical of urban areas, as evidenced by several 311 calls in 2021-2024 regarding street cleaning, parking violations, and garbage collection concerns, though these are generally minor and not directly related to the building's condition. The comprehensive renovation work completed between 2021-2024 demonstrates a significant investment in the property's safety, comfort, and modern amenities, with particular attention paid to meeting contemporary fire safety and building code requirements.
