1157 Kansas St, San Francisco, CA 94107

The two-unit residential building at 1157 Kansas Street in Potrero Hill, owned by Gerard J Donnellan, is a two-story flats and duplex structure constructed in 1926. The property has undergone several significant improvements in recent years, including a comprehensive electrical system upgrade in November 2020 that included a 200-amp service upgrade, installation of unit sub-panels, and the addition of multiple dedicated outlets throughout both units. The building received a new roof in June 2022 at a cost of $19,500, and in 2019, important maintenance work was performed on the front brick facade, including repairs to angle irons and addressing leaking brick veneer.

An earlier roofing project from 1993 is no longer active. The property has experienced recurring maintenance issues with the surrounding infrastructure, particularly the sidewalk, which has shown multiple defects. Notable events include three separate reports of collapsed sidewalks between February and April 2019, though these were either not found to be hazardous or were resolved through inspection.

More recent concerns include a defaced sign in November 2023, graffiti on the sidewalk in October 2023, and an open sidewalk defect report from October 2023. The building's immediate area has also experienced periodic issues with illegal parking on the sidewalk, with reports in February 2023 and August 2019. The property has been maintained actively by its owner, with all building permits showing "Complete" status, indicating proper adherence to regulations and successful completion of the work.
