3524 21st St, San Francisco, CA 94114

The property at 3524 21st Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood. Built in 1900 and currently owned by Leach Family LP, this flats/duplex structure has undergone several significant maintenance and repair activities over the years. Most notably, in 2012-2013, the building faced multiple building code violations that were documented in December 2012 and resolved by March 2013, including issues with weatherproofing, inadequate handrails, window repairs, interior plaster damage, and concerns regarding lead-based paint.

During this period, the property underwent reroofing work with a permit issued in December 2012, though there were multiple complaints in March 2013 about roofing work being conducted without proper permits. The building's electrical system received an upgrade in 2004 with a 200-amp PG&E underground installation. More recent history shows limited but relevant activities, including a routine reroofing project in 2013 costing over $20,000, and some maintenance activities like window repairs and handrail installations.

The building experienced some construction-related issues in January 2014, when complaints were filed about interior work and floor sanding without visible permits. The property's 311 call history shows typical neighborhood concerns, including an abandoned vehicle report in 2019, a noise complaint in 2018, and some street lighting issues in 2013 that were resolved promptly. Throughout its history, the building has maintained compliance with major building codes since the 2012-2013 violations were addressed, though the pattern of complaints and violations in late 2012 suggests there had been some deferred maintenance issues that required attention during that period. The property has undergone various routine maintenance and upgrading work over the years, with particular attention to roofing systems being a recurring focus.
