4731-4733 Mission St, San Francisco, CA 94112

The property at 4731-4733 Mission Street is a two-story, four-unit multi-family residential building constructed in 1949, currently owned by Sally L Liu. Recent complaints (2023) indicate ongoing issues with common area lighting and vacant storefronts, part of a pattern of concerns about the building's maintenance and habitability. The building has a documented history of infrastructure and maintenance issues, particularly during 2016-2018, including problems with heating systems, windows, and roof-related water damage.

Multiple permits show repairs to these systems, including heater replacements, window installations, and roof work totaling substantial investment amounts. There was a period of significant code violations and complaints in 2016-2017, involving heating system failures, window maintenance, and various interior surface problems, most of which were addressed through subsequent repairs and improvements. More recent history shows electrical upgrades underway in 2024, with a permit issued for the replacement of electrical systems, though there are still active complaints about lighting and common area maintenance as of mid-2023.

The building has undergone various improvements over the years, including reroofing projects in 2016-2017 and the installation of new central heaters, though maintenance issues have persisted. Historical complaints from 2000 regarding fire safety (manual release at doors and egress obstruction) suggest ongoing attention to building safety systems. The property has also experienced recent exterior maintenance issues, as evidenced by multiple 311 calls regarding cleaning and graffiti in 2023. A significant portion of the building's history involves compliance work and repair projects related to various code violations and tenant complaints, reflecting ongoing challenges with maintaining building systems and addressing tenant concerns promptly.
