171 11th Ave, San Francisco, CA 94118

The two-story, six-unit multi-family residential building at 171 11th Ave, owned by Thomas A Ho Jr, was constructed in 1962 in the Lake-Presidio neighborhood. The building's maintenance history includes several significant roofing and siding projects, with reroofing work performed in 1990 and 2003, and vinyl siding installation on the rear and south walls in 2000. Of particular concern is an active soft-story seismic program complaint filed in August 2019 regarding the building's unregistered status, which remains unresolved as of the latest records.

The property has undergone multiple housing inspections over the years, with routine inspections conducted in 1996, 2000, 2007, and 2011 revealing various safety concerns. These included issues with the central fire alarm system, gas utility shutoff tools, and fire safety certifications, all of which were addressed by February 2011. The building's documented history shows attention to basic maintenance requirements, including termite repairs in 1993 and various inspections.

While the residential unit's maintenance record shows regular upkeep through roofing and siding improvements, the pending soft-story registration remains a notable concern. Recent 311 calls near the property (from 2019 to 2023) primarily relate to street and sidewalk issues outside the building's immediate scope, including parking enforcement, street cleaning, and sign repairs. The history of building permits shows proper documentation of major improvements, though there was one instance in 2003 where reroofing work was performed without a permit, which was subsequently resolved.
