313 28th St, San Francisco, CA 94131

The property at 313 28th Street is a two-unit multi-family residential building located in Noe Valley, constructed in 1900 and owned by Mark L Collins. The building has undergone significant renovations, most notably in 2008-2009, when a comprehensive interior remodel was completed including new bathrooms, kitchens, laundry facilities, and a complete electrical system upgrade with rewiring of both units, hydronic radiant floor heating, and two new water heaters.

Structural improvements during this period included the replacement of a PSL beam with a steel beam and ceiling modifications. The most recent major work on the building was completed in August 2023 with a $22,000 reroofing project. The building's maintenance history shows regular upkeep and addressing of infrastructure needs, including a service panel upgrade in 2009 and repair of electrical code violations in 2003.

There have been multiple 311 calls regarding the property, primarily between 2019 and 2024, though these were mostly related to parking enforcement issues and tree maintenance rather than building conditions. Two notable modifications were proposed but have not been documented as completed: a horizontal expansion at the rear of the building measuring approximately 10 feet in length, and the addition of living space with a rear deck on the ground floor. The building has received appropriate permits and completed inspections for all major work undertaken.
