4051-4053 18th St, San Francisco, CA 94114

The property at 4051-4053 18th Street, a 2-story multi-family residential building with 3 units constructed in 1920, is owned by 4051 18th Street LLC and includes a commercial space. In 2015-2016, the building underwent significant renovations including the addition of massage rooms and improvements to disabled access facilities, though these projects triggered multiple complaints about accessibility issues, particularly regarding bathroom facilities. These complaints, along with concerns about unauthorized electrical work and water intrusion problems, were eventually abated by 2016.

The building also houses a significant telecommunications installation, with AT&T equipment modifications occurring in 2005, 2009, 2016, and 2017, including the installation and relocation of antennas, remote radio units, and associated electrical work. A notable violation was recorded in 2012 regarding unapproved cellular installation work, though this was abated by 2013. Recent activity (2024-2025) has primarily involved external issues around the property, including multiple reports of garbage and debris, illegal postings, and two encampment-related complaints in early 2025.

The building experienced three fire incidents between 2001 and 2002, with two being intentionally set outside rubbish fires and one false alarm, though fortunately none resulted in civilian injuries. The property has maintained an active permit history, with the most recent building work involving electrical and plumbing improvements in 2017, including the installation of multiple fixtures and electrical systems. The building's ongoing maintenance appears to be handled through regular permit processes, with most historical violations and complaints having been resolved promptly.
