239 Mullen Ave, San Francisco, CA 94110

The two-unit residential building at 239 Mullen Ave in Bernal Heights, owned by Joseph A. Najera, is a one-story flats and duplex structure built in 1900 that has undergone several significant maintenance and safety improvements over the years.

The property has shown recent maintenance attention with a complete reroofing project in March 2023 costing $15,000, and earlier repairs to a rear landing and stairs in March 2020 addressing safety concerns. Notably, the building faced serious safety issues in 2002 when violations were recorded regarding the rear wooden deck's condition, citing dry rot, pest damage, and settlement concerns, particularly relating to its support for a hot tub. These violations, which were abated in 2007, led to subsequent repair work including a 2003 deck repair project and multiple complaints through 2020 regarding its property line positioning and construction methods.

The property has made environmental improvements with the installation of solar panels in 2011 (1.17 kW system) and 2018 (1.45 kW system). Recent maintenance history shows ongoing attention to structural integrity, particularly regarding the deck/landing areas which have been the focus of multiple repair projects and inspections. The building's recent history (2022-2024) has primarily consisted of external issues not directly related to the building's condition, such as parking violations and street maintenance concerns, though there were also some complaints about street pavement defects and general cleaning needs in 2022.
