645 44th Ave, San Francisco, CA 94121

The three-unit, two-story multi-family residential building at 645 44th Avenue in the Outer Richmond, owned by Abraham Mertens and Ivory Mad, has a documented history of both maintenance and violations spanning several decades since its construction in 1926. Most recently, in 2020, there were significant modifications to the ground floor unit C, including water damage repairs and relocation of the front entry door, which followed an April 2020 complaint about unauthorized construction work during the pandemic. Prior to this, major renovations were completed in 2017-2018, including a kitchen remodel with electrical and plumbing upgrades, and a bathroom renovation, all of which were properly permitted and completed.

The building has experienced several maintenance issues over the years, with the most significant cluster of problems occurring in 2003, including violations related to inadequate heating, damaged windows, and ceiling repairs, all of which were resolved by May 2003. There were also multiple complaints between 2017-2020 regarding unpermitted work, particularly concerning electrical and structural modifications, though these issues were eventually addressed through proper permitting processes. The property's maintenance history shows regular upkeep, including a complete reroofing in 2002, window replacements in 2003, and various interior improvements over the years.

While there have been several complaints about waste management issues in 2018 and parking concerns in 2020, these were generally routine neighborhood maintenance matters. The building's electrical and plumbing systems have received attention over the years, with significant upgrades noted in 2017, including new wiring, outlets, and plumbing fixtures. Despite the periodic issues with unpermitted work and maintenance violations in the early 2000s, the recent history of permitted renovations and repairs suggests improved compliance with building codes and regulations.
