412-414 Hoffman Ave, San Francisco, CA 94114

The three-unit, three-story multi-family residential building at 412-414 Hoffman Avenue in Noe Valley, owned by Turner Charles B Jr Owyang, was constructed in 1908 and has undergone several significant renovations and maintenance projects over the past decades. The most recent major work on the property includes a sewer pipe replacement in August 2021, which involved replacing the house line and 20 feet of sewer pipe towards the foundation.

In 2011, substantial repairs were carried out to address dry rot issues, including work on the front stairs, rear stairs and deck, laundry room, installation of a new water heater pedestal, bathroom remodeling in unit #3, and replacement of multiple windows and doors, accompanied by relevant plumbing and electrical work. The building has seen various improvements over the years, including the installation of a fire sprinkler system in 1992, a vertical addition in 1991, and multiple unit-specific upgrades such as kitchen cabinet replacements in 1994 and bathroom/ laundry relocations in 2011.

More recent maintenance includes a water heater replacement in 2008 and a gas houseline extension in 2012, though both those permits are now expired. The property has had minimal issues reported through the 311 system, with the most recent case in September 2023 concerning loose garbage on the street which was promptly resolved by the Department of Public Works. The building's permit history suggests regular maintenance and proactive addressing of structural and safety concerns, particularly with the focus on addressing dry rot in 2011 and the installation of modern safety features like the sprinkler system in 1992.
