1056 Potrero Ave, San Francisco, CA 94110

The property at 1056 Potrero Avenue is a three-story mixed-use building constructed in 1907, currently undergoing significant redevelopment under owner Macs Development LLC. The building's recent history is marked by substantial renovation attempts, beginning in 2016 with a major project that aimed to convert the existing structure into a five-apartment building with new bike parking, exterior improvements, and sprinkler systems. This initial project has evolved through several permits, with the most recent approved plans proposing the creation of 3 dwelling units and 6 ADUs within the existing building envelope, increasing the total unit count to 9. A voluntary seismic upgrade was also undertaken in 2020 to address soft-story concerns.

The property has experienced multiple compliance issues and construction challenges over recent years. Between 2016 and 2019, several Notices of Violation were issued, including concerns about weatherproofing, abandoned building status, egress obstructions, and sanitation issues, all of which were eventually abated. More recent complaints from 2022-2024 have raised serious concerns about building conditions, including reports of water intrusion, fire safety issues, structural problems, and abandoned construction status. The building has also faced multiple fire code violations related to storage and exit pathways in 2018, though these were processed as duplicate complaints. As of December 2024, there are active complaints regarding blight and an unregistered abandoned vacant building status.

The extensive permit history includes significant infrastructure work, such as plumbing upgrades for multiple units, electrical improvements, and seismic retrofitting, though some permits have expired without completion. The property's planning history reveals attempts to reconfigure its use, initially proposing four condominium units before ultimately seeking to create nine units through various modifications. The building's recent status has raised concerns about potential abandonment, with multiple complaints citing peeling paint, unauthorized postings, and various maintenance issues. The situation has sparked community interest, as evidenced by numerous 311 calls in 2024 regarding illegal postings, graffiti, and general maintenance concerns. Recent planning records indicate a revised dwelling unit configuration was proposed, including substantial vertical and horizontal additions to the original structure, though recent activity suggests the project has experienced significant delays and compliance challenges.
