4126-4128 24th St, San Francisco, CA 94114

The property at 4126-4128 24th Street in Noe Valley is a two-unit, two-story multi-family residential building with commercial space, constructed in 1900 and currently owned by Kathleen Jordan. The building is undergoing significant safety improvements, with multiple permits issued in 2024 for the installation of an NFPA 13 sprinkler system throughout the residential portions, though the commercial space's sprinklers are being handled under separate permits. The property has seen extensive renovations over recent years, including a major $842,000 rear addition completed in 2022 that added a garage, reconfigured living spaces, and new roof deck.

The building has received several infrastructure upgrades, such as the installation of radiant floor heating in both residential units (2022), foundation improvements to the commercial space (2021), and the recent addition of a roof-mounted solar PV system (2024). The building's history includes some maintenance challenges, particularly regarding sewer issues, with at least two reported sewage backup incidents in 2020-2022. There were also complaints about unauthorized office use in 2007, which was resolved.

Recent renovation work has included various plumbing and electrical upgrades, such as kitchen renovations, laundry room improvements, and comprehensive rewiring projects. The property has undergone numerous environmental and efficiency upgrades, including a planned electric car charger installation (though recently withdrawn), reflecting modern sustainability considerations. While the building's maintenance record shows periodic issues, most recent permits and improvements suggest ongoing investment in safety, comfort, and modern amenities for residents.
