4579-4581 Mission St, San Francisco, CA 94112

This two-story mixed-use building at 4579-4581 Mission Street, constructed in 1909 and currently owned by Demetrios & Kyriaki Simotas, contains three residential units above a ground-floor commercial space. The property has undergone several significant maintenance and improvement projects over the past decade, including a substantial $48,000 concrete floor replacement in 2020, a bathroom window frame replacement in 2022, and various electrical upgrades including a PG&E installation of three meters and panels in 2005.

Notable building violations were recorded in July 2017, including issues with lead paint, rodent infestation, handrail repairs, and safety systems (smoke alarms and carbon monoxide detectors), though these were all abated by January 2018. More recently, the building has experienced recurring maintenance issues and tenant concerns. In 2022, there were complaints about late-night noise from the taqueria (which operates below the residential units) and violations of construction work hours.

The property has also faced some fire safety compliance concerns in late 2024, with violations issued for operating without a permit and change of use, both referred to hearing. Recent maintenance records show ongoing issues with graffiti (with multiple reports throughout 2023-2024) and occasional sewer problems, including a sewage backup incident reported in May 2024. The building's history includes various infrastructure upgrades, such as sewer line replacement in 2015, furnace replacement in 2013, and earlier electrical system improvements in 2005, indicating ongoing efforts to maintain essential building systems.
