3141-3145 23rd St, San Francisco, CA 94110

The property at 3141-3145 23rd Street is a two-story, multi-family residential building constructed in 1900, currently owned by Rebirth & Development Inc, containing three units. The building has experienced several significant events over its history, with the most notable being a serious fire incident in February 2021 involving an electrified greenhouse that was operating without proper permits; this fire endangered adjacent structures and resulted in one unintentional building fire classification, though thankfully no civilian injuries were reported.

Following this incident, there were multiple complaints regarding unpermitted work, including foundation work in an area previously occupied by the burned greenhouse, and concerns about the scope of fence replacement work exceeding permitted limits. The building's recent history shows ongoing maintenance and improvements, including a properly permitted fence replacement project in 2021 (though it was later revised in 2022 to decrease footing size), and various plumbing and infrastructure updates such as the installation of a backflow assembly in 2013 and ventilation improvements in 1995.

Historical records indicate earlier renovations including bathroom plumbing work in 1998, accessibility improvements in 1993, and the installation of a fire suppression system in 1993, though some of these permits have expired. The property has been subject to multiple 311 calls in recent months (October-November 2024) primarily related to garbage and debris on the property, as well as reports of encampments in the vicinity, though these are external to the building itself. While the building has a history of permit violations and unpermitted work, particularly relating to the 2021 fire incident, recent permitted improvements suggest ongoing management of the property.
