735-737 Haight St, San Francisco, CA 94117

The two-unit residential building at 735-737 Haight Street, owned by the Richard Oconnor Living Trust, is a 2-story flats and duplex structure built in 1913 in the Hayes Valley neighborhood. Recent activity includes a filed permit from September 2023 for the installation of a power door operator to improve disability access, though other recent permits show minimal construction activity.

The building has undergone several significant renovations and maintenance work over its history, including a 2006 project to replace a rear storage/roof deck/stair structure valued at $20,000, and electrical and plumbing upgrades in 2009 involving rewiring storage areas and relocating laundry facilities. A notable complaint was filed in June 2009 regarding construction debris accumulation in the backyard, though this was promptly abated within a week. The property has experienced three documented carbon monoxide-related incidents, including detector activations and a CO incident, though no civilian injuries were reported in any case.

The building's maintenance history shows attention to infrastructure, with work done to repair area drains, electrical systems, and address previous fungus damage discovered in 1991. A recent interior renovation project was completed at 737 Haight Street to relocate a kitchen and create a new bedroom in Apartment Unit 2. Current environmental conditions around the property have been documented through 311 calls, with multiple reports of street cleaning issues and graffiti between July and December 2024, though these appear to be more related to public space maintenance than building-specific issues.
