1052 Potrero Ave, San Francisco, CA 94110

The property at 1052 Potrero Ave is a 2-story, 4-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, owned by Mario and Dolores Maso and built in 1923. The building has undergone several significant improvements in recent years, with the most substantial work occurring in 2012 when Unit #4 received comprehensive updates including a kitchen renovation ($17,000) with new cabinets and appliances, as well as plumbing and electrical work. Major infrastructure improvements include a sewer line and housetrap replacement in 2010, and reroofing work completed in both 2010 ($7,500) and 1992.

A concerning incident occurred in late 2019 when a facade collapse during construction raised safety concerns about unbraced rear walls, though this issue was eventually resolved by June 2022. The building has a history of inspections and violations, with a significant 2000 inspection revealing multiple safety concerns including egress obstruction, inadequate lighting, and fire extinguisher maintenance issues, all of which were abated by August 2000. Recent maintenance and environmental issues around the property have been documented through 311 calls, with the most recent concerns in 2023 involving flooding, hazardous materials, and overflowing city garbage cans.

These external issues, while not directly related to the building's structural integrity, reflect current neighborhood conditions. The building's management has addressed all documented violations and completed necessary repairs over the years, with no active violations or complaints as of the current date. The property has undergone regular maintenance and improvements, with particular attention paid to both unit-specific upgrades and building-wide systems. The most recent building permit activity was recorded over a decade ago, suggesting either stabilization of the building's condition or a potential reduction in necessary improvements.
