404-406 Utah St, San Francisco, CA 94110

The two-unit residential building at 404-406 Utah Street in Potrero Hill, owned by David M. Pfister, is a two-story flats and duplex structure built in 1890. The building has a limited permit history, with three significant permits from the late 1980s: a cancelled permit from 1988 intended to remodel an unoccupied space into a bedroom, an expired permit from 1988 for garage ceiling insulation work, and a completed permit from 1985 for constructing new walls in the rear yard.

Recent activity around the property has been primarily street-related, with several 311 calls documenting various urban management issues. In 2024, there were two garbage and debris incidents (one involving human waste), and a 2023 encampment report that couldn't be verified. Prior to these, there were two documented cases of driveway blocking in 2021 and 2019, with one resulting in a citation.

The building's vicinity has experienced occasional quality-of-life issues, including noise complaints in 2020, incidents of waste requiring cleanup in 2020, and reports of graffiti on the mailbox in 2018. Multiple street cleaning and general service requests were made in 2018 through the Department of Public Works. While these exterior issues have been addressed through various municipal responses, it's important to note that the building itself has not required significant permits or modifications in recent years, and the documented concerns primarily relate to street and sidewalk conditions rather than the building structure or systems themselves.
