465-467 Crestmont Dr, San Francisco, CA 94131

The property at 465-467 Crestmont Drive is a two-unit residential building constructed in 1968, currently classified as a Flats & Duplex structure. The building has undergone significant renovations and faced several regulatory challenges throughout its history. Most notably, in 2007, a complaint was filed regarding unauthorized modifications that converted what was legally a two-unit building into a three-unit structure, including the addition of an illegal studio unit with its own entrance, bathroom, and kitchen.

This violation, along with associated issues like dry rot on the balcony deck, prompted multiple rounds of inspections and permit requirements between 2007 and 2016. The building underwent substantial electrical upgrades in 2008-2010, including a 200-amp service installation and new panels for both units, though some permits expired or were canceled during this period, requiring subsequent renewals and corrections. Recent history shows several maintenance and compliance issues, including a 2024 report of loose garbage and multiple abandoned vehicle complaints in 2022 and 2025, though these are more related to street conditions than the building itself.

The property has been the subject of various municipal service calls, including reports of hazardous materials and sidewalk blockages in 2018, all of which were resolved. The most recent significant building-related activity appears to be completed inspection work in 2016 that addressed multiple previous permits, suggesting that major compliance issues were resolved at that time. The building's history includes multiple permit applications for final inspections between 2009 and 2016, indicating a thorough but protracted process to bring the property into full compliance with current standards.
