636-640 Washington St, San Francisco, CA 94111

The three-story multi-family residential building at 636-640 Washington Street, owned by Hui Fmly Revoc Tr, comprises 7 units and was constructed in 1907. The property has undergone significant recent improvements, including major tenant improvements in 2023 costing $181,000 to rebuild a mezzanine floor, basement staircase, and ADA bathroom, along with a current $30,000 project issued in August 2024 to replace the storefront frame and glass and add an ADA entrance.

Of particular concern are recurring fire safety issues, with multiple violations between 2020 and 2024, including blocked exits and various fire code violations, though most have been promptly corrected. The building has also experienced administrative challenges with fire safety compliance, resulting in violations in mid-2024 related to fire command center features, extinguishers, and doors, though records indicate many of these have been abated.

Historic violations from 2000-2013 included issues with stairs, smoke detectors, and other safety systems, though these were resolved. Recent infrastructure work includes plumbing and electrical upgrades as of December 2023, while routine inspections and responding to violations, particularly regarding fire safety, have been a recurring theme in the building's maintenance record. The property is also subject to commercial parking garage renewal processes, indicating an active and ongoing relationship with city planning and regulatory requirements.
