3634-3650 23rd St, San Francisco, CA 94110

The three-story, nine-unit multi-family residential building at 3634-3650 23rd Street in Noe Valley, owned by Whelan Family Ptnrs, has a documented history spanning several decades. Built in 1910, this flat & store building experienced significant fire damage in 1988, which required comprehensive repairs including window, sheetrock, and door replacements, all of which were completed. More recent structural concerns have primarily focused on the rear stairs, with documented repairs in 1988 and 2007, the latter addressing a specific violation requiring the replacement of a post.

A notable building issue emerged in 2010 regarding an unauthorized deck construction by tenants at 3628 23rd Street, though this was eventually resolved by 2012. The building underwent a thorough inspection process in 2001, which revealed multiple violations that were subsequently addressed by June 2001, including sanitation issues, stair repairs, security upgrades, and gas utility requirements. More recent improvements include the installation of a new 100-amp electrical service in 2009.

The property has experienced recurring issues with garbage management, as evidenced by multiple 311 calls in late 2024 regarding debris and waste outside the building. Between November 2024 and January 2025, there were several reports of illegal parking and garbage concerns, though most were either resolved or officers were unable to locate the reported issues. A single hazardous condition incident was recorded on the property with no civilian injuries noted, though no specific date was provided for this event.
