3500-3502 23rd St, San Francisco, CA 94110

The property at 3500-3502 23rd Street in Noe Valley is a 2-story multi-family residential building constructed in 1906, containing 3 units and currently owned by Matthew and Sofia Keck. The building has undergone several significant renovation projects over the years, including a major bathroom remodeling project in 2005 (though the permit eventually expired), kitchen renovations, and substantial electrical upgrades with multiple completed permits between 2005-2008 showing installation of new circuits, lights, and a 200-amp service.

In January 2021, the building suffered exterior damage from a car incident that required repairs to wood and stucco, along with initial safety concerns about the main gas line and evidence of dry rot, though these issues were resolved by the following April. The building has had recurring maintenance and code compliance issues, particularly in the 2000-2010 period, including violations related to unapproved dwelling unit construction, stair repairs, and various safety requirements such as the need for smoke detectors and fire-resistant materials. Multiple complaints have been filed regarding unpermitted construction work, with the most recent active complaint from 2020 alleging construction noises and materials being brought in and out of the building.

More recently, there have been ongoing concerns about parking violations near the property, with multiple citations issued for sidewalk parking and driveway blocking between 2023-2024. The property was previously involved in an illegal short-term rental violation, which was resolved with penalties paid. Planning records show various proposals and inquiries, including attempts to verify zoning compliance and a canceled request for a larger development project that would have added additional units and an ADU to the site.
