4011-4015 18th St, San Francisco, CA 94114

The three-unit residential building at 4011-4015 18th Street, owned by Tom Y K Lee & Janice S Lee, is a three-story flat and store structure built in 1900 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant improvements over the past three decades, with the most substantial renovations occurring between 2014-2016, including a comprehensive kitchen and bathroom remodeling project ($35,000) with new fixtures and LED lighting, electrical service upgrade to 200 amps, and the installation of new smoke detectors.

A notable safety concern emerged in 2003 when complaints were filed regarding unsafe rear stairs and landing work completed without permits, though this issue was subsequently addressed with proper repairs and permits. More recent developments include a sidewalk excavation incident in December 2024 that sparked concerns about unauthorized construction work, and there have been periodic issues with a vacant storefront (2020) and various debris cleanup matters in the vicinity, though these were not directly related to the building's residential units.

The property has maintained a relatively clean violation record since the early 2000s, with no active violations on file as of the latest data. Recent maintenance activities suggest ongoing property upkeep, with the 2014-2016 renovation period representing the most significant investment in building improvements in recent history.
