2700-2702 21st St, San Francisco, CA 94110

The property at 2700-2702 21st Street is a two-story, multi-family residential building constructed in 1909, currently owned by York St LLC and located in San Francisco's Inner Mission neighborhood. The building has undergone significant recent renovations, most notably in 2021-2022 when a commercial space was converted into a residential unit with 3 bedrooms and 2 baths, including the installation of an NFPA 13D fire sprinkler system (cost $300,000). Additional improvements included a complete electrical overhaul for the new unit, bathroom and kitchen renovations, and the installation of a new heating system (2023).

The property has experienced several maintenance and compliance issues over the years, including multiple vacant storefront complaints between 2019 and 2020, plumbing-related concerns in 2016, and an unauthorized auto repair business operating out of garages in 2005-2006. The building received a fire code violation in 2006 regarding the need for fire extinguishers, though this was subsequently resolved. Recent activity at the property has generated numerous 311 calls in 2024 primarily related to garbage and debris removal from the surrounding area, though these appear to be external rather than building-specific issues.

The most recent significant building improvement was the installation of a new split system heat pump and associated plumbing work in early 2023. The property has maintained active compliance with building codes since the resolution of previous violations, and all major recent improvements appear to be properly permitted and completed, including comprehensive plumbing upgrades involving bathroom, kitchen, and sewer system improvements between 2021 and 2022. The building's historical records show a pattern of commercial-to-residential conversions and infrastructure upgrades, with the most recent phase focusing on modernizing safety systems and residential amenities.
