1664-1668 Newcomb Ave, San Francisco, CA 94124

The two-unit residential building at 1664-1668 Newcomb Ave in Bayview is a 2-story flats and duplex structure built in 1907, currently owned by Andrew L Harris. Notable recent improvements include the installation of a dedicated sprinkler monitoring system in 2019, comprehensive renovations in 2018 including kitchen remodels, bathroom updates, and washer/dryer installations on multiple floors, and substantial safety upgrades including a new fire service and NFPA 13 wet-pipe sprinkler system in late 2018.

The building underwent significant compliance work in 2017-2018 to address a violation from 2016 related to unauthorized unit conversions, which included legalizing an additional unit and correcting various code violations involving unapproved electrical and plumbing work, improper egress, and heating system deficiencies. Additional improvements over the years include reroofing work in 2018, furnace replacement, and various plumbing upgrades. The property has experienced some recurring issues with garbage and debris on the property, with multiple reports filed in December 2024, though these were mostly addressed through standard municipal resolutions.

A historical plumbing complaint from 1999 regarding drainage connections was resolved in early 2000. The building's recent improvements, particularly the sprinkler system installation and unit legalization process, suggest significant efforts have been made to improve safety and compliance standards. The property's maintenance history shows regular updates to essential systems and living spaces, though prospective tenants should be aware of the building's history of unauthorized modifications that required subsequent remediation work to achieve compliance with housing codes.
