671-673 Spruce St, San Francisco, CA 94118

The two-family residential building at 671-673 Spruce Street, located in the Jordan Park/Laurel Heights neighborhood and owned by John A & Doreen Maria Hash, has undergone several notable improvements since its construction in 1928. The property has seen a consistent pattern of window upgrades over the past decade, with recent work in 2019 and 2017 focusing on non-street-facing window replacements, transitioning from aluminum to vinyl and fiberglass materials. In 2016, significant modifications were attempted with a withdrawn permit for rear decks and followed by a completed project that included installing two wood decks and replacing second and third-floor windows with glass sliding doors.

Earlier improvements included a 2014 project that replaced four aluminum windows on the front facade with fiberglass frame windows. The building's history includes a 1995 legalization of existing ground floor units, which followed an illegal unit complaint filed in 1995, though this complaint was abated by December of the same year. More recent history reveals typical urban maintenance issues, with the most recent incidents being graffiti in 2023 and 2021, both of which were resolved.

Other 311 calls have included requests for street cleaning, a temporary moving sign in 2021, and a red curb request that was completed in 2015. A reroofing project was recorded in 1988, while a 1995 permit for ground floor legalization indicates prior concerns about unit configuration. The building has undergone regular maintenance and upgrades, with particular attention paid to improving energy efficiency through window replacements, as evidenced by the documented U-factor specifications in various building permits.
