406-408 Buchanan St, San Francisco, CA 94102

The two-unit building at 406-408 Buchanan Street in Hayes Valley, owned by Brian Tobin and Amy Simon, is a two-story flats and duplex structure built in 1900. The property has undergone several significant renovations over the past decade, including a major conversion of the basement to a garage in 2013 ($200,000), installation of a sprinkler system in 2014 ($8,000), and multiple unit renovations between 2017-2024.

Recent work in Unit 4 in 2024 involved obtaining final inspections for previously completed work, while Unit 2 received substantial updates in 2019 including new kitchen cabinets, bathroom fixtures, and electrical system improvements. The building experienced multiple permit-related issues, with some work being completed without proper permits, though these have since been regularized through subsequent permits. The property has a history of maintenance and safety concerns, particularly during a 2008 routine apartment house inspection that identified multiple violations including issues with fire escape ladders, stairs, water heaters, and exterior doors, though these were abated by June 2008.

More recently, in 2019, there were complaints about excessive construction noise and outdoor sawing activities, and in 2014, there was an issue with a dumpster blocking a neighbor's garage. The building's infrastructure improvements included a gas line installation in 2016, a comprehensive electrical upgrade in 2019, and various plumbing upgrades. Community concerns have been primarily focused on street cleaning issues, with multiple 311 calls in 2023-2024 related to garbage, debris, and waste removal, though these are primarily external to the building itself.
