1040 De Haro St, San Francisco, CA 94107

1040 De Haro Street is a two-unit, two-story multi-family residential building located in Potrero Hill, built in 1924 and currently owned by Yew Mona. The property has undergone significant improvements and maintenance over the past decade, with major renovations including a horizontal rear addition completed in 2017 ($35,000), multiple kitchen and bathroom remodels between 2011-2020 ($55,000 in 2020 alone), and essential infrastructure upgrades such as a complete reroofing in 2015 ($13,725) and electrical system overhaul in 2008 ($18,000). The building improvements have focused on modernizing essential systems, with new siding installations, window replacements, and comprehensive electrical and plumbing upgrades, including multiple furnace installations and ductwork updates.

The property has maintained a relatively stable condition with all major permits marked as complete, though there is one recent open issue regarding sidewalk tree root damage reported in July 2023. The building has experienced regular maintenance and upgrades, including safety and efficiency improvements such as new windows with modern U-factors, though it's worth noting that the 2012 proposal for a 245 sq. ft.

third-floor expansion was cancelled. The area around the building has had typical urban maintenance issues, with multiple parking enforcement calls between 2022-2024, though these are external to the building's condition. A tenant buyout of $75,000 occurred in December 2021 at an adjacent property (1052 De Haro Street), though this does not directly affect the current building's status.
