1264 17th Ave, San Francisco, CA 94122

This two-unit, two-story multi-family residential building located at 1264 17th Avenue in San Francisco's Inner Sunset neighborhood was built in 1906 and has undergone several significant modifications and legalizations over its history. The most notable recent work includes the legalization of a ground floor ADU (accessory dwelling unit) in 2019-2020, which involved the installation of new fire safety systems including sprinklers (20 heads) and a fire alarm monitoring system, as well as plumbing upgrades for new water meters, bathroom remodels, and electrical improvements (200 amp service with 3 meters).

The building had a documented history of unauthorized unit conversions, with a violation filed in 2002 regarding an illegal ground floor unit and a similar complaint in 1995 about unauthorized kitchen installations, though these issues were subsequently abated. Earlier improvements to the property include a roof replacement in 2011, furnace installation in 2015, and various maintenance items.

The building experienced one notable infrastructure issue in 2018 with a sewage backup that was promptly addressed by PUC Sewer Operations. There is a history of abandoned vehicle complaints in the vicinity, with multiple reports between 2012 and 2019, though these are unrelated to the building's condition or management. The property's legalization process and recent improvements suggest active management and compliance with current building codes, particularly regarding fire safety systems.
