4054-4056 26th St, San Francisco, CA 94131

The property at 4054-4056 26th Street is a two-unit, 2-story multi-family residential building located in Noe Valley, built in 1900 and currently owned by the Linlin G Wills Living Trust. The building has experienced several significant maintenance and compliance issues over the past two decades, with the most recent concerns centering around sewer system problems. In early 2025, there were multiple sewage backup incidents from the side sewer vent reported in January and December, though these were resolved through field work and inspection.

The property underwent important plumbing modifications in 2011 to address violations, including changes to the dryer vent system and corrections to improper pipe connections that were causing water pressure issues. Earlier in its history, the building underwent various repairs in 1999-2000, including foundation work, kitchen and bathroom remodeling, and repairs to rear doors and stairs. The building has a documented history of building code violations and compliance issues, particularly in 2011 when multiple violations were identified, including problems with moisture exhaust ducting for clothes dryers, stair repairs, and lead paint concerns that required special handling procedures.

These violations were all officially abated by January 2012. More recently, a notice of violation was issued regarding illegal short-term rentals in 2023, though the status indicates it was closed with listings removed. The property has also experienced some infrastructure challenges outside the building itself, as evidenced by multiple 311 calls regarding sewer issues and a sidewalk defect noted in 2020-2021. While the building has had its share of maintenance and compliance issues, the majority of historical violations have been addressed, with the most pressing current concerns relating to the sewer system based on the recent 311 calls.
