635-637 Connecticut St, San Francisco, CA 94107

The property at 635-637 Connecticut Street is a three-story, two-unit multi-family residential building located in Potrero Hill, owned by Arthur C & Cheryl Ann Agnos and constructed in 1964. The building has undergone several significant improvements over the past two decades, with the most recent major work being a roofing project completed in 2020 that involved installing new four-ply tar and gravel roofing to comply with California's cool roof requirements, at a cost of approximately $21,500. The building underwent substantial renovations in 2013, including kitchen remodels, bathroom renovations, and the installation of a solar panel system (3.185 kW with 13 roof-mounted modules) along with a 100-amp electrical service upgrade.

This renovation work also included replacing three FAU units with 80% AFUE systems and updating ductwork that previously contained asbestos. Earlier modifications were attempted in 2005 to enclose a basement deck and add a bathroom, though these permits were ultimately cancelled. The building has experienced minimal issues that required attention, with the most notable being a complaint in December 2020 regarding unpermitted construction signs and a porta-potty placement during renovation work, which was subsequently addressed through proper permitting.

Recent activity at the property includes a 2024 Rent Board request that resulted in a status change from 2 exempt units to 2 rentals, and a tree maintenance issue reported in August 2024. The surrounding area has experienced several infrastructure-related issues, particularly regarding pavement conditions, with multiple reports of pavement defects on Connecticut Street between 2010 and 2017. The property has generally maintained compliance with building codes and regulations, with all significant renovation work having obtained proper permits and undergone necessary inspections.
