750 27th St, San Francisco, CA 94131

The property at 750 27th Street in Noe Valley is a three-story multi-family residential building constructed in 1939, currently owned by James A. Collins and Jeffrey Parker, containing two units. The building has undergone significant improvements over the past three decades, including the 2013-2014 conversion of space into a new one-bedroom unit with modern amenities, complete with a new hydronic heating system, lighting, windows, and doors, at a cost of $100,000.

More recent improvements include the installation of a non-combustible metal gate in 2020 and the addition of 18 roof-mounted solar PV modules in 2013. The building's infrastructure has received attention with the installation of a 410-gallon rainwater harvesting system in 2011. Maintenance and safety records show periodic updates to individual units, including bathroom remodels in 2005 and 2006, and documented electrical and plumbing work to support building improvements.

Of particular concern are recent sewer issues, with two reported sewage back-up discharge incidents from side sewer vents in December 2024 and January 2025. The building has experienced relatively few emergency incidents, with fire department responses primarily for system activations or non-emergency situations, and there have been no documented fire-related injuries. A conditional use authorization was previously approved to add a second dwelling unit at the ground level, requiring a variance from parking requirements. The property's recent history includes several parking-related enforcement actions and a water leak incident in November 2024, though these appear to be infrastructure maintenance issues rather than indications of systemic problems.
