3001-3005 20th St, San Francisco, CA 94110

The property at 3001-3005 20th Street is a three-unit, three-story multi-family residential building located in San Francisco's Inner Mission neighborhood, currently owned by Waconda Trust and built in 1900. The building has undergone several significant maintenance and repair works over the past two decades, most notably in 2024 with a sewer line repair and in 2022 with an electrical service upgrade.

A substantial renovation in 2016 addressed both ground floor bathroom and second floor sunroom issues, including footing replacement and dry rot repairs, costing approximately $12,000. However, recent concerning developments emerged in 2024, with a building complaint filed regarding unauthorized construction work related to a laundromat installation in the main building, reportedly conducted by the owner without proper permits. This situation is particularly troubling considering the historical context of the building's complaints, which include a 1994 report of rat infestation, water leakage issues in 1996, and multiple building inspection records showing ongoing maintenance concerns.

The property has experienced a series of fire safety system activations, though all incidents recorded were either unintentional or due to system malfunction, including several smoke detector activations and a gas leak incident. The building and surrounding area have generated numerous 311 calls between late 2024 and early 2025, primarily concerning garbage and debris on the street, for which multiple cases were resolved. While historical permits show various maintenance work, such as window and lightwell repairs in 2001 and street space improvements in 2010, the most pressing current concern appears to be the ongoing unpermitted work related to the commercial space, which has reportedly been vacant for several years.
