131-133 Duncan St, San Francisco, CA 94110

The two-unit residential building at 131-133 Duncan Street in Noe Valley is a 1912 flats and duplex structure currently owned by the Hatley-hall Family Trust. The property has undergone several significant improvements over the past decade, with the most recent work being a bathroom remodel scheduled for late 2024 at an estimated cost of $28,192. Major upgrades were completed in 2013 during a condo conversion process (report #7190), including the installation of two new high-efficiency furnaces with ductwork, comprehensive window and door replacements (19 windows and 1 door), and garage modifications including storage room construction and concrete slab replacement.

The building received a new roof in 2018, and more recent plumbing updates in 2022 included kitchen and laundry improvements for both units. The property's maintenance history shows regular upkeep, with particular attention paid to energy efficiency and safety improvements. The 2013 renovations included significant HVAC upgrades, including the replacement of old furnaces and associated ductwork.

The upcoming bathroom remodel, currently permitted as of December 2024, focuses on interior updates. While the building has experienced typical neighborhood issues such as reports of abandoned vehicles (in 2015 and 2018), these were external to the property and were promptly addressed by city services. The street space permit from 2013 and various plumbing and electrical permits over the years indicate ongoing attention to building systems and infrastructure. The condo conversion process was officially completed and approved in 2013, transitioning the property to its current ownership structure.
