522-524 7th Ave, San Francisco, CA 94118
The property at 522-524 7th Avenue in the Inner Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1910, currently owned by Gary C. Chan and Mee Woon. The building has undergone several bathroom remodeling projects in recent years, with the most recent permit issued in May 2024 for a comprehensive bathroom remodel on the second floor costing $33,600, following a completed partial bathroom renovation in February 2024 ($5,000).
The building has a notable history of compliance issues and repairs, particularly during the 2010-2012 period when multiple violations were documented regarding an unsafe rear staircase and concerns about an alleged illegal dwelling unit in the basement area. These violations, which included safety issues and unauthorized construction, were eventually resolved through various repair contracts including reroofing (2011), stair repairs, and addressing dry rot issues. More recent history shows the building has experienced some maintenance challenges, including a complaint in 2011 regarding malfunctioning appliances and plumbing issues, though these appear to have been addressed.
In 2022, there was a complaint about unauthorized construction work, but this issue is noted as not active. The property has undergone regular maintenance and improvements in recent years, as evidenced by the sequence of bathroom renovation projects. A 311 call from 2018 regarding a blocked driveway was closed as invalid due to lack of required contact information. While the building's history includes periods of significant code enforcement activity, particularly in the early 2010s, there have been no documented active violations in recent years, suggesting improved compliance with building regulations and maintenance requirements.
