27 Lexington St, San Francisco, CA 94110

27 Lexington Street is a two-story, four-unit multi-family residential building constructed in 1924, currently owned by the Helen Mar Chin Revocable Trust and located in San Francisco's Inner Mission neighborhood. The property has undergone several significant modifications and improvements over the past decade, with the most recent major work being a $16,000 reroofing project completed in 2019. In 2012, the building underwent substantial ground floor renovations including the legalization of rooms as a playroom, storage, and half bathroom, accompanied by electrical and plumbing upgrades.

This followed previous work in 2009 to address building violations, which involved converting bedrooms to storage rooms, repairing stairs, removing a wet bar, and legalizing a half-bath, with all related electrical and plumbing work completed successfully. The building has a history of maintenance and compliance challenges, particularly evident in 2003-2004 when multiple housing violations were documented, including issues with paint, fire safety, electrical systems, and plumbing. These violations were subsequently addressed and abated by September 2003.

A proposal to create a fifth dwelling unit on the ground floor of the existing four-unit building was submitted and approved in planning records, though the status of this conversion remains unclear in the building permit records. Recent activity at the property has primarily involved external maintenance and cleaning, with multiple 311 calls for street cleaning and general upkeep between 2022-2024, though these issues pertain more to the surrounding area than the building itself. The most recent building intervention was a street space and sidewalk repair permit issued in 2009, and there have been no documented major building violations or complaints since 2008, suggesting improved maintenance and compliance in recent years.
