187-197 Duncan St, San Francisco, CA 94110

The 4-unit, 2-story multi-family residential building at 187-197 Duncan Street in Noe Valley, owned by Ralph F. and Carole E. Johnson, has undergone several significant maintenance and repair projects since its construction in 1923.

Most recently, in 2022, the building received a $29,000 reroofing project and underwent dry rot repairs at the rear upper level. The building had multiple fire safety violations noted in a September 2010 routine inspection, including issues with fire proofing materials, fire extinguishers, and means of egress, though all were resolved by November 2010. The property has a history of addressing structural maintenance needs, with earlier repairs documented in 2008 including repairs to stairways affected by dry rot. The building's rooftop has been a site of communication equipment installation and subsequent removal, with complaints filed in 2012 regarding unauthorized 4G equipment installation affecting residents' telephone service.

This issue was temporarily resolved through an electrical permit in 2015. The property has undergone regular inspections over the years, including a 2009 routine inspection of common areas, and has maintained compliance with necessary repairs and improvements as required by building codes. More recent 311 calls related to the property primarily concern street cleaning and parking issues, with the most recent being an encampment report from June 2024 that was unable to be verified by authorities. The building's maintenance record shows a pattern of addressing both immediate safety concerns and longer-term structural maintenance needs, with all known violations being resolved through appropriate remediation work.
