1434-1438 Union St, San Francisco, CA 94109

The three-unit residential building at 1434-1438 Union Street in San Francisco's Russian Hill neighborhood is a three-story flats and duplex structure built in 1908 and currently owned by Diane M. Josephs. The property has undergone several significant improvements over the past two decades, with the most recent being a complete reroofing project completed in 2024 costing $20,000.

Notable structural improvements include an earthquake retrofit in 2018 that involved bolting and shearwall installation at the ground floor/basement area, and the replacement of 15 front-facing windows with Marvin wood clad units in 2013. Earlier improvements include the installation of four garage sprinklers in 2004 and the replacement of ten rear vinyl windows in 2007. The building has experienced several compliance issues in the past, particularly in 2002-2003, including safety violations related to handrail requirements, egress obstructions, and unpermitted water heater installations with incorrect flue materials.

All of these violations were subsequently abated, with the handrail and egress issues being resolved by December 2002, and the water heater violations addressed by October 2003. There were also complaints regarding unauthorized construction hours in February 2004 and concerns about unpermitted garage work, both of which were resolved promptly. The most recent incident was a minor issue with abandoned furniture reported in July 2024, which has been resolved. The building's maintenance record shows regular upkeep and modernization efforts, particularly in terms of seismic safety and water system improvements, though there was a period of multiple compliance issues in the early 2000s that has not been repeated in recent years.
