520-522 Sanchez St, San Francisco, CA 94114

The three-unit, multi-family residential building at 520-522 Sanchez Street is a 1905 structure located in the Eureka Valley/Dolores Heights neighborhood, currently owned by Lance Alan Carnes. The property has undergone significant recent improvements, including a complete reroofing project (April 2023) costing $24,800, window replacements (February 2023) with energy-efficient fittings, and dry rot repairs to the rear siding (January 2023). A major electrical upgrade was completed in December 2022, involving a full rewiring of unit one, and previous notable improvements include a complete sewer line replacement (July 2008) and furnace installations (December 2008).

The building's history reveals several concerning periods, particularly around 2007-2009, when multiple building code violations were documented regarding an unauthorized third unit on the garage level, complete with kitchen and bath facilities. This situation led to enforcement actions in 2007-2008, resulting in the removal of the illegal unit and various compliance requirements, including the installation of fire-grade drywall, heating systems, and proper electrical wiring. The property has also experienced maintenance challenges, including a sewage incident in 2008 requiring demolition of contaminated drywall, and a heating system complaint regarding inadequate heat in 2008 and hot water issues in 2021.

More recently, the building has shown consistent maintenance improvements, with multiple permits for roofing, window, and siding work being properly executed and completed. Historical issues such as sidewalk defects, general cleaning needs, and noise complaints have been documented through 311 calls, primarily relating to exterior conditions rather than internal building issues. The property's planning records show compliance with window replacement requirements, with work completed as per regulations. While the building's past includes significant code violations and maintenance challenges, the most recent records indicate proper attention to building improvements and maintenance requirements, though occasional heating and water system issues have been reported through complaints.
