40 Ashbury St, San Francisco, CA 94117

The two-unit multi-family residential building at 40 Ashbury Street, constructed in 1916 and currently owned by the Thomas Dey Trust, has undergone several significant improvements and maintenance work over the past three decades. Most recently, in 2024, the electrical service was upgraded from 100 amps to 200 amps, representing a substantial modernization of the building's infrastructure. The property has seen various system upgrades, including the replacement of water heaters and installation of high-efficiency furnaces in 2015, and in 2014, there was a comprehensive window replacement project that installed energy-efficient wood double-hung windows throughout the building.

The building's history includes several major maintenance and safety improvements, such as an in-kind window replacement in 2014, reroofing projects in 2013 and 1990, and structural work including the repair of outside stairs in 2001 and replacement of sheet metal pan with stucco patching in 1993. Notably, during 1990, important seismic safety improvements were made, including the legalization of mudsill anchor bolts and plywood bracing of garage walls. The property has experienced some utility-related issues, with documented sewage backup and flooding incidents in June 2012, though these were resolved promptly through professional interventions.

The building's recent history shows regular maintenance and improvements, with most significant work focused on system upgrades and energy efficiency. The surrounding area has experienced typical urban challenges, as evidenced by various 311 calls regarding street cleaning, parking issues, and occasional encampments, though these are primarily external to the building itself. A tree health assessment in 2019 noted concerns about plant placement affecting a tree's health, but this was not directly related to the building's condition. The property's maintenance record demonstrates ongoing attention to infrastructure upkeep and safety standards, with no recent pattern of unresolved maintenance issues or safety concerns.
