514 Missouri St, San Francisco, CA 94107

The property at 514 Missouri Street in Potrero Hill is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by J Nels Mc Williams. The building has undergone several significant improvements over the past decades, with a particular focus on window upgrades and maintenance.

Most notably, between 2013 and 2022, the property has seen consistent window replacements and upgrades, including recent installations of energy-efficient fibrex windows with low U-factors. The building's roof has been maintained regularly, with reroofing projects recorded in 1997, 2003, and 2018, demonstrating ongoing commitment to roof maintenance. A significant bathroom remodel was completed in 2014, including associated plumbing and electrical work, with proper permits obtained and documented.

The property's infrastructure maintenance has been proactive, with the most recent plumbing work in 2022 involving the replacement of the house trap on the sewer lateral, indicating attention to essential systems. While there have been two 311 calls recorded, one in 2019 regarding sidewalk parking (which was resolved with the responding officer unable to locate the vehicle), and another in 2024 concerning a sign repair, neither incident raised concerns about building safety or resident experience. The comprehensive record of permits and completed work suggests regular upkeep and modernization of the property, with particular attention to energy efficiency through window upgrades and general maintenance of major systems.
