1716-1720 Broadway, San Francisco, CA 94123

The two-unit residential property at 1716-1720 Broadway in Pacific Heights, owned by Jay P & Rita A Castello, is a two-story duplex built in 1940. The building has undergone several significant improvements over the years, with the most recent being a major window upgrade in 2015 that involved replacing twelve Fibrex windows on the rear facade, achieving a U-factor of less than .32, and costing over $25,000. This followed an earlier window retrofitting project in 2010 that cost approximately $4,100.

The building's maintenance history shows attention to basic infrastructure, including reroofing projects in 1993 and 2003, though the 1993 permit has expired. An interior renovation in 1999 involved updating bathroom fixtures. The property has experienced relatively few issues over recent years, with no recorded fire incidents or civilian injuries.

Recent municipal engagement includes a 2023 encampment report that was closed unable to locate, a resolved abandoned property pickup request in 2020, and a potentially extensive utility excavation investigation in 2019 that ultimately concluded with plate removal and restoration. A graffiti incident on a sign was reported and resolved in 2016. The building's documented permit and incident history suggests regular maintenance and upgrading of essential systems, particularly focusing on energy-efficient window improvements.
