442 11th Ave, San Francisco, CA 94118

The property at 442 11th Ave in San Francisco's Inner Richmond district is a two-unit, two-story multi-family residential building constructed in 1916, currently owned by Han Marital Trust. The building has undergone several significant renovations and improvements over the past three decades, with the most recent major work occurring in 2014, including electrical upgrades with the replacement of a meter box and gas line repairs. Prior to this, substantial interior remodeling was completed in 2006-2007, which included kitchen and bathroom renovations, electrical updates, and some structural improvements.

These 2006-2007 renovations initially prompted building violations for unauthorized work, as new framing, plumbing, and electrical work had begun without proper permits, though these issues were eventually resolved by January 2007. The building has a documented history of maintenance and compliance issues that have been addressed over time. In 2009, the garage level received structural enhancements including post and beam upgrades, foundation tie-downs, and plywood shear walling as recommended by an engineer.

A violation in 2014 was filed regarding unpermitted plumbing work on the garage pipes, which was subsequently resolved. During the 2006 renovation period, there was a complaint about an improperly installed exhaust pipe and balcony roof modification, though these issues appear to have been addressed. The property's exterior maintenance included stucco wall repairs in 1993, and permits for various electrical and plumbing works show ongoing infrastructure maintenance. Recent activity around the property primarily consists of standard urban issues such as parking enforcement cases and street maintenance requests, which are typical for the neighborhood and do not directly relate to building conditions or resident safety.
