2455-2457 Folsom St, San Francisco, CA 94110

The two-unit residential building at 2455-2457 Folsom Street in San Francisco's Inner Mission neighborhood is a two-story flats and duplex structure owned by Parsons Trust and constructed in 1900. The building's maintenance history indicates several significant repairs focused on structural integrity and safety, including interior stairway repairs in 2010, and more substantial waterproofing work in 2007 when roof rafters and parapet walls were repaired due to water damage and dry rot issues, with a subsequent revision of these repairs recorded in December 2007.

The property has also undergone some infrastructure upgrades, including the conversion from overhead to underground electrical service in 2004, and a complete reroofing in 1995. The building experienced a safety compliance issue in 2009 related to an unauthorized exterior wooden utility ladder, which was resolved within approximately one month through proper notification and remediation processes.

Recent maintenance concerns in the surrounding area have included multiple reports of sidewalk parking violations between 2021 and 2024, though these are more related to street conditions rather than building maintenance. Other municipal service calls near the property have addressed various urban infrastructure issues, including a sewage backup incident in March 2022 that was promptly resolved by city services, a damaged tree report in March 2023, and some instances of loose garbage and graffiti that were addressed by Department of Public Works services.
