4158-4160 26th St, San Francisco, CA 94131

The property at 4158-4160 26th Street is a two-story, multi-family residential building located in Noe Valley, containing three units and owned by David Shaw & Niloufer Ichap. Built in 1900, this flats and duplex-style building has undergone several significant improvements over the past three decades.

In the 1990s, major structural work was completed including basement excavation, foundation replacement, shear wall installation, and a seismic upgrade. More recent improvements during 2012-2013 focused on exterior maintenance, with permits issued for replacing rear exterior stairs, reconstructing portions of rear and side walls, and various interior updates including electrical wiring work and plumbing modifications (specifically toilet removals and reinstallations). The property's maintenance history shows regular addressing of infrastructure needs, including a tree maintenance response in 2017 regarding a street tree potentially damaging the building, and handling of pavement defects reported in 2019.

Recent 311 calls suggest ongoing parking enforcement issues in the vicinity, with multiple reports of driveway blocking between 2019 and 2024, though most were either unable to be verified or resolved without citation. The most significant recent event was a tenant buyout at the neighboring address (4152 26th Street) in May 2020, involving three tenants and a payment of $30,000. The building's location and age suggest typical urban residential maintenance patterns, with periodic updates and historical structural improvements.
