217-219 9th Ave, San Francisco, CA 94118

The two-unit residential building at 217-219 9th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1906, currently owned by the Mung Family Trust. The property has undergone several significant maintenance and improvement projects over the past few decades, with the most recent being the installation of vinyl siding on the right side walls in late 2017, which cost $18,844 and involved 1216 square feet of non-visible side wall coverage.

Prior major work includes a roof replacement in 1997 and foundation reinforcement in 1995, which included the installation of anchor bolts with epoxy and replacement of one sill. The building has experienced minimal incidents that might impact resident experience, with only one construction-related complaint filed in July 2011 regarding debris disposal during construction work, though this issue was addressed on the same day it was reported.

A 311 call regarding illegal postings was logged in October 2014, noting that posters had been up for over 70 days, though this was promptly resolved by the Department of Public Works. The property's permit history suggests regular maintenance and upgrading of the building's structural elements, with no recorded safety violations or recurring issues in recent years.
