454 Gates St, San Francisco, CA 94110

The two-unit residential building at 454 Gates Street in Bernal Heights, currently owned by Lisa A Nickell 2019 Trust, is a 2-story flats and duplex structure built in 1906. The property has undergone several significant renovations and improvements over recent years, with the most recent work in 2023 involving a $30,000 kitchen remodel including new circuitry, plumbing upgrades, and window replacement. Prior improvements include a 2020 bathroom renovation, 2019 window replacements, and substantial electrical system upgrades including new subpanels and additional outlets.

The building's systems have seen considerable modernization, with the replacement of two furnaces and installation of a new PVC flue in 2019, along with comprehensive electrical improvements including the installation of a 70-amp kitchen subpanel. Of particular note is the building's history of violations and complaints, most notably a 2007-2008 incident involving unpermitted deck construction that required abatement through proper permitting in 2008, which was finally resolved in 2019. A vacant building registration was filed in 2020, and there was a complaint in 2011 regarding unpermitted renovation work, though this was quickly resolved.

Recent maintenance records show attention to building systems and infrastructure, including reroofing work completed in 2006. The property has experienced some recent parking-related issues, with multiple citations issued for parking violations in late 2023/early 2024, though these are external to the building itself. A December 2023 environmental health complaint was recorded and transferred to the Department of Public Health for follow-up. The building has a single documented fire incident from 1993 involving downed power lines, with no civilian injuries reported.
