381-383 31st Ave, San Francisco, CA 94121

The two-unit residential building at 381-383 31st Avenue in the Central Richmond neighborhood is a two-story structure built in 1985, currently owned by Stanley J. and Nancy K. Tun.

The building has undergone several significant improvements since its construction, with the most recent being a substantial $37,100 reroofing project completed in March 2023, representing ongoing maintenance of the property'scritical infrastructure. Prior to this, in 2021, the property received an upgrade to its windows, with the installation of seven new energy-efficient E-Series windows with a U-factor of 0.30 or better, replacing older non-street-facing aluminum units. The building's window improvements began earlier in 2006 when permits were pulled for replacing ten street-visible windows, switching from aluminum to wood composite materials, although these permits ultimately expired without record of completion.

The property's permitting history indicates proper attention to maintenance and upgrades, particularly regarding energy efficiency improvements. The only recorded incident affecting the property was a sidewalk obstruction complaint in January 2019 involving a mobile storage container, which was promptly resolved by the Department of Public Works. This isolated incident had no direct impact on the building's safety or resident experience and was handled through standard municipal procedures.
