603 Hayes St, San Francisco, CA 94102

The property at 603 Hayes Street is a two-story multi-family residential building with three units, constructed in 1900 and currently owned by Hayes Valley Properties LLC. The building has undergone several significant improvements and maintenance activities over the years, with the most concerning recent activity being two fire violations issued in March 2023 related to combustible materials and unsafe building conditions, though records indicate these were abated.

The building experienced substantial plumbing infrastructure work in 2013, including replacing gas pipes in the basement and fixing gas leaks in Unit 1. Other notable infrastructure improvements include a reroofing project completed in 2008, a kitchen equipment renovation in 2007, and various electrical upgrades including the replacement of kitchen receptacles.

The Hayes Street property has a history of responding to safety and maintenance issues, with multiple fire alarm activations recorded (all determined to be unintentional or due to malfunction) and several fire inspections resulting in violations that were subsequently corrected. The building has maintained its basic systems, with a 2014 bathroom renovation and various other updates to keep the facilities current. The surrounding area has experienced some street maintenance issues recently, with multiple reports of garbage and debris in early 2025, though these were not directly related to the building itself.
