231-233 Connecticut St, San Francisco, CA 94107

The two-unit residential building at 231-233 Connecticut Street in Potrero Hill is a two-story structure built in 1926, currently owned by Leah Friend & Stephen Allen. The property underwent significant improvements in recent years, with major renovation work commencing in 2018 that included a vertical addition to convert the upstairs unit from 2 bedrooms/1 bath to 3 bedrooms/2.5 baths, and the downstairs unit from 1 bedroom/1.5 baths, along with various plumbing upgrades and foundation work. More recent improvements included the installation of new heating systems with a high-efficiency furnace and heat pump in 2021, and electrical upgrades including a panel upgrade and rewiring work, though the latter was ultimately cancelled.

The building has experienced some notable issues during its renovation period. In March 2021, there was a tenant complaint regarding construction safety concerns involving smoking and sawdust on-site, which was documented through the 311 system. More recently, in December 2024, there was a sewage back-up discharge incident from the side sewer vent that was resolved by PUC Sewer Operations.

The property has undergone necessary infrastructure improvements, including sewer lateral replacement in 2015 and various plumbing upgrades in 2020-2021 adding new bathrooms with underground and gas lines. Historical records show earlier maintenance work in the 1990s for dry rot issues and cabinet replacement, indicating past structural concerns that appear to have been addressed. The building is currently listed as multi-family residential and has completed multiple permit requirements for its renovation work, including obtaining CEQA clearance and meeting building department standards.
