1714-1718 20th St, San Francisco, CA 94107

The three-unit, two-story multi-family residential building at 1714-1718 20th St in Potrero Hill, owned by Fiore3 LLC, was constructed in 1906 and has undergone several significant maintenance and compliance events over the years. Most recently, the property experienced multiple sewage backup incidents in October 2023, which were promptly addressed by PUC Sewer Operations.

In 2015, the building underwent important safety improvements following a routine housing inspection in September 2014, which had identified multiple violations including fire safety concerns, staircase maintenance issues, and the need for various structural maintenance affidavits. These violations were all successfully abated by February 2015 through the installation of handrails and spindles on the rear yard stairs and other necessary safety updates. Prior to these events, the building underwent substantial structural work in 2005 with the installation of underpinning piers at the west property line, and earlier repairs in the 1990s addressed various maintenance issues including termite damage and the replacement of wood shingles.

The property has maintained regular housing inspections, with records showing compliance with identified violations. Recent maintenance requests include attention to street signage (2024) and various infrastructure issues, though these are not directly related to building safety or habitability. While the building's history shows regular upkeep and response to violations, the recurring sewage issues in 2023 represent the most significant recent maintenance challenge.
