517 36th Ave, San Francisco, CA 94121

The three-story multi-family residential building at 517 36th Avenue in the Outer Richmond, owned by Maria A Vitrano, was originally constructed in 1928 and contains 12 units. The property has undergone several significant improvements over recent years, with the most notable being a comprehensive fire alarm system upgrade in 2023 costing $44,530, which included installing low frequency sounders in sleeping areas and updating notification systems in common areas. The building completed mandatory seismic soft-story retrofitting in 2016, involving reinforcement of the ground floor with new shear walls and foundation improvements, and received its Certificate of Final Completion.

The property has been actively maintaining its infrastructure, including the 2022 installation of three additional ADU units at the first floor, representing a total of 15 units, and previous upgrades such as multiple window replacements, roofing work in 2004, and various plumbing improvements including steam boiler and water heater replacements. The building has experienced several regulatory and maintenance challenges, particularly related to its boiler system and fire safety requirements. There have been multiple instances (2004, 2010, 2017, and 2022) regarding boiler permit renewals and violations, though these issues were consistently addressed and resolved, with the most recent violation being corrected in January 2023.

Historical complaints from 2004 included issues with combustible storage, fire escape maintenance, and plumbing/electrical violations, all of which were abated by January 2005. The building's systems have generally been well-maintained, with records showing regular updates to essential infrastructure such as the fire alarm system and HVAC equipment, though occasional lapses in permit renewals have occurred. Recent inspections have resulted in the "Condition Corrected" status for a fire alarm systems issue in September 2024, though this appears to be a recent development as of my knowledge cutoff.
