501 Hayes St, San Francisco, CA 94102

501 Hayes Street is a 19-unit, 3-story multi-family residential building constructed in 1900, owned by Bogart Terry & Mullin-bogar. The property has undergone significant recent improvements, including the installation of washer/dryer facilities in units 1 and 4 in September 2024, and compliance with the mandatory seismic retrofit program (completed in 2020 with separate permits for residential and commercial components).

The building has experienced some notable issues in recent years, particularly concerning noise and vibration disturbances in unit 3 on the second floor, reportedly due to a commercial refrigerator compressor and mechanical unit installed underneath the bedroom. Complaints about this situation were filed between November and December 2023, citing noise levels exceeding permissible limits and vibrations affecting sleep quality. Other recent building activities include a ground floor restaurant renovation in 2021 (valued at $310,000) with various improvements and accessibility upgrades, and the completion of multiple fire safety improvements in 2022, including the connection of an Ansul system to the fire alarm.

The property has maintained compliance with various building codes and requirements, though there were some fire safety violations noted in 2023 regarding general unsafe buildings and hazardous materials, which have since been addressed. Historical records from 2010 show a series of building violations concerning mold, kitchen repairs, and window issues in unit 6, all of which were abated by November 2010. The building's maintenance history shows regular updates to electrical systems, including recent work in 2024 to accommodate laundry facilities, and various plumbing and lighting improvements over the years, suggesting ongoing investment in property maintenance and upgrades.
