3487-3491 17th St, San Francisco, CA 94110

The property at 3487-3491 17th Street, located in Mission Dolores, is a three-unit, three-story multi-family residential building constructed in 1914. The building has undergone several significant improvements in recent years, most notably the installation of a comprehensive fire sprinkler system in 2017, followed by the addition of a dedicated functions sprinkler monitoring system in 2018, indicating a commitment to fire safety improvements.

Between 2016 and 2017, substantial interior renovations were completed, including bathroom additions, electrical upgrades with a new 400-amp panel, and various unit modifications. A 2014 complaint about unauthorized basement unit construction and a 2017 complaint about ongoing construction work beyond permitted hours were filed but were subsequently closed. The building's maintenance and safety history shows a pattern of addressing various interior issues between 2006 and 2011, including problems with windows, stairs, walls, ceilings, smoke detectors, and mildew in bathrooms, though all these violations were abated by March 2007.

The property has maintained its compliance with safety standards since then, with no active violations on record. Recent activity at the address has primarily involved external issues such as street cleaning, debris removal, and parking enforcement matters, with the most recent building-related service call in December 2023 regarding garbage can repair. The most recent planning record indicates a completed conversion of 525 square feet of storage space into residential living areas, though this was noted as having no proper enclosure between floors per the current configuration at the time of inspection.
