657-665 47th Ave, San Francisco, CA 94121

The 5-unit, 2-story apartment building at 657-665 47th Avenue in the Outer Richmond district, owned by Juan C Kong & Donna Kempner, has undergone several significant maintenance and improvement efforts since its construction in 1952. Most notably, the building completed its mandatory soft-story seismic retrofitting under Tier 3 requirements, receiving its Certificate of Final Completion (CFC) for this important safety upgrade. Recent improvements include a north side/rear fence replacement in 2020 (cost: $8,000) and the installation of gas fireplace inserts throughout in 2016, along with associated gas line installations.

The property has experienced some structural maintenance challenges, particularly regarding exterior stairs, with violations documented in 2019 concerning dry rot, guardrail issues, and failed plywood sections. These violations were addressed through permit work totaling $4,000, though the building had previously faced similar stair-related concerns in 2007 that resulted in violation notices and abatement proceedings. Historical records show various system upgrades, including electrical panel improvements and garage door installations in 2007, as well as plumbing work involving laundry room and water heater relocations.

The building's maintenance history also includes resolution of a 2007 complaint regarding an unauthorized roof structure over an open staircase, which was subsequently permitted and completed. A 2018 issue involving a damaged tree on the property was addressed and resolved by the Department of Public Works. While the building has experienced periodic maintenance challenges, particularly concerning exterior structures, owners have consistently addressed violations through proper permits and repairs, demonstrating ongoing investment in building upkeep and safety compliance.
