864 De Haro St, San Francisco, CA 94107

The three-story multi-family residential building at 864 De Haro Street in Potrero Hill, owned by Richard L Hall, was constructed in 1900 and contains two units. The property has undergone several significant infrastructure improvements over the past decade, most notably the recent installation of a ductless multi-split heat pump system, completed in June 2024, along with the associated electrical work. Prior improvements include a sewer lateral replacement completed in 2017 and a roof replacement in 2013.

The building has experienced recurring sewer-related issues, with three documented sewage backup incidents between 2017 and October 2023, all of which were resolved by PUC Sewer Operations. More recent maintenance issues were primarily related to street cleaning, with reports of loose garbage in late 2023 and early 2024, though these were general neighborhood maintenance matters rather than building-specific problems. The property's historical permit records show earlier improvements, including the installation of a fireplace in 1990, and an expired roofing permit from 1989, though these are less relevant given their age.

The building's recent service history indicates ongoing maintenance and infrastructure upgrades, particularly in 2024 with the installation of modern climate control systems. While the property has experienced some sewer system challenges in recent years, these have been addressed through appropriate municipal services. The frequency of 311 calls has decreased significantly in recent years, with only minor street cleaning issues reported in 2023/2024 compared to more substantial infrastructure work documented in earlier years. The most recent service interactions have primarily involved external street and sidewalk maintenance rather than building-specific concerns, suggesting that the property's internal systems have received adequate attention through the completed permits and repairs.
