4254-4258 18th St, San Francisco, CA 94114

The property at 4254-4258 18th Street is a three-unit, three-story multi-family residential building with commercial space, built in 1906 and currently owned by the Kenneth R Shimmon Revocable Trust. The building has undergone several significant improvements over the years, including a complete reroofing project in 2007 costing $40,000, window replacements, and electrical upgrades in 2014 that focused on kitchen circuits. In 2001, the building experienced multiple violations related to safety concerns, including issues with handrails, stairs, and a roof deck, which were all resolved by January 2002.

The property has had periodic maintenance work, such as street space permits and gas line extensions in 2008. More recently, the building has been the subject of multiple 311 calls and complaints, particularly in late 2024-early 2025, regarding sidewalk conditions and parking issues. There were three "Shared Spaces" complaints in October 2023, with two referred to other agencies and one found to have no merit.

The most recent building-related permits were issued in 2019 for streetspace work. The property's historical records show regular maintenance and infrastructure improvements, though some plumbing permits from 2008 were marked as expired. The building's systems have been periodically updated, as evidenced by the electrical work completed in 2014, which included adding new circuits and plugs to the kitchen areas.
