3877-3879 Jackson St, San Francisco, CA 94118

The property at 3877-3879 Jackson Street is a historic 2-story, 2-unit multi-family residence built in 1910, currently owned by Ashford Ventures LLC. The building's recent history includes several significant developments related to unit legalization and renovation plans.

In early 2024, a major renovation project was proposed (though subsequently cancelled) that aimed to remodel the building, legalize an unauthorized dwelling unit (UDU) to an accessory dwelling unit (ADU), upgrade code compliance features including stairs and egress paths, and improve various interior and exterior elements. This larger project was initially identified as requiring Historic Planning review due to its impact on the front façade and would necessitate a variance for rear setback encroachment. The building has a documented history of unauthorized unit usage and rental violations, with multiple reports of short-term rental activity across all three units (3877, 3879, and 3879A), though these complaints were ultimately determined to have "No Violation" status.

Infrastructure issues have been present, including multiple sewer-related incidents in 2022-2023, and various maintenance concerns have been addressed over the years, such as a complete reroofing project in 2006 and a plumbing repair in 2012. The property has experienced some recent maintenance challenges, as evidenced by multiple 311 calls in 2023-2024 regarding graffiti, illegal postings, and general cleaning issues. The current owners acquired the property in 2022 with intentions to remodel for personal use, particularly for their growing family, while the planning records indicate ongoing interest in combining and legalizing existing units to align with zoning requirements.
