731-733 Vermont St, San Francisco, CA 94107

The two-unit, three-story multi-family residential building at 731-733 Vermont Street in Potrero Hill, owned by James K Mackey, was constructed in 1910 and has undergone several significant maintenance and improvement projects over the years. In 2005, substantial roofing work was completed at a cost of $23,740, including the removal of composition and wood shingles and installation of new plywood sheathing, along with the installation of solar modules and a solar inverter system on the roof.

Earlier maintenance included window repairs completed in 1996. A safety concern was documented in 1997 regarding insufficient railing height in the stairwell, though this issue was ultimately resolved. In recent years, the property has experienced recurring sewer system issues, with two documented sewage back-up incidents in late 2024 from the side sewer vent.

The building's surrounding area has faced various municipal service issues, including an open encampment cleanup case (as of September 2023), multiple reports of abandoned vehicles in 2024, and infrastructure concerns such as a damaged tree (October 2024) and an overflowing city garbage can (May 2024). While the majority of these external issues have been resolved through appropriate city departments, they indicate ongoing challenges in the immediate vicinity of the property. The building's maintenance record shows attention to both structural and environmental improvements, particularly with the addition of solar technology in 2005, though recent plumbing system concerns may warrant monitoring.
