Augrented Insights Report

The historical multi-family residential building at 3520 23rd Street in Noe Valley, constructed in 1904, currently houses 7 units across 2 stories. The property owner, Colleen Cottrell Lawrence, has maintained the building through several significant upgrades, with the most recent being a complete fire alarm system overhaul in 2021, replacing an earlier system and complying with San Francisco's fire safety requirements.

The building underwent a mandatory soft-story retrofit in 2015, demonstrating compliance with earthquake safety regulations. Historical maintenance records show attention to basic infrastructure needs, including a 2000 reroofing project and 1998 dryrot repairs. The building has experienced several safety-related issues over the years, with the most recent cluster of concerns emerging in late 2022 involving fire escape maintenance and smoke/carbon monoxide detection compliance, though these violations were promptly addressed and abated by January 2023.

Earlier issues from 2002 regarding kitchen ventilation and fire escape maintenance were similarly resolved within a month. The property has maintained an active response to various maintenance needs as demonstrated by multiple 311 calls for street cleaning, tree maintenance, and sewer issues between 2015-2024, though these external issues were not directly related to the building's condition. Three parking enforcement incidents occurred recently (in 2019 and 2024), indicating occasional parking-related challenges in the vicinity of the property.
