670 De Haro St, San Francisco, CA 94107

The two-story, five-unit multi-family residential building at 670 De Haro Street in Potrero Hill, owned by C & B Properties, has undergone several significant maintenance and safety improvements since its construction in 1965. Most notably, the building completed its mandatory soft-story retrofit in 2016 (costing $37,000), achieving compliance with SFBC Chapter 34B requirements and receiving its Certificate of Final Completion (CFC) as a Tier 3 property.

The building has maintained regular safety inspections through Housing Inspection Services, with records showing routine inspections in 2001, 2002, 2009, and 2015. A 2001 inspection revealed a fire escape drop ladder violation that was promptly addressed the same day. The building has undergone several major maintenance projects, including a reroofing project in 2013 (costing $18,678), though records indicate this permit expired.

A subsequent permit obtained in 2014 was for securing final inspection on work previously approved in 2013. More recently, there was a street cleaning issue reported through 311 in January 2023, though this was related to external conditions and not the building itself. While the building has a history of approximately five routine safety inspections over the years, with only one violation recorded and promptly resolved, all major structural safety requirements, including the critical soft-story retrofit, have been completed, demonstrating compliance with current safety standards.
