221-223 Connecticut St, San Francisco, CA 94107

The two-unit, two-story residential building at 221-223 Connecticut Street in Potrero Hill, owned by Whitmore Residuary Tr, was constructed in 1906 and has experienced several maintenance and infrastructure issues over the past decades. The building's records indicate a persistent problem with the sewer system, particularly between 2014 and 2022, with four documented sewage backup incidents involving 4-inch vent issues between October 2014 and June 2016, followed by a similar incident in January 2022.

Other maintenance work includes successful completion of reroofing in 1991 and installation of kraftile stair treads over existing terrazzo steps in 1993. More recent history shows relatively few issues, with the most recent incidents being a holiday-related street cleaning matter in January 2023 and three parking-related enforcement actions between 2018-2019, all of which were properly addressed by city authorities.

In 2017, there was a complaint about a residential totter blocking the sidewalk, which was noted but not scheduled for inspection. The building's infrastructure improvements, though limited to the early '90s, suggest past attention to maintenance, while the cluster of sewer-related incidents in the mid-2010s denotes a period of particular plumbing challenges. The most recent building permit on record, from 2016, was for a street space permit with minimal associated cost.
