3616-3618 20th St, San Francisco, CA 94110

The property at 3616-3618 20th Street in the Mission Dolores neighborhood is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by Edward H & Cynthia W Davis. The building has undergone several significant improvements over the past 15 years, with the most substantial work focusing on structural reinforcement and safety upgrades. In 2009, the ground floor perimeter walls received voluntary strengthening with 1/2" plywood and epoxy reinforcement, costing approximately $4,000.

The following year, a $15,000 permit was issued to complete related work. Earlier, in 2007, the building underwent insulation improvements in laundry rooms and first floor areas, installation of 5/8" Type X fire-rated walls, ceiling insulation, and new windows in stair walls, with an estimated cost of $18,000. The building's maintenance record shows regular upkeep, including a gas line rerouting in 2008 and various related work permits.

Recent activity at the address shows primarily routine urban issues such as parking enforcement matters, with several reported incidents of vehicles blocking driveways between 2021 and 2024. The property has experienced typical urban neighborhood challenges as evidenced by multiple 311 calls for street cleaning, waste removal, and minor incidents like defaced street signs, but these do not directly relate to the building's condition or management. A fire alarm system activation was recorded, though it was determined to be unintentional with no injuries or fire damage reported. The most recent building-related activity was recorded in January 2024, focusing on parking enforcement.
