40-42 Parsons St, San Francisco, CA 94118
The two-unit residential building at 40-42 Parsons Street in Lone Mountain, owned by Nicholas Bonn, is a two-story flats and duplex structure built in 1914. The property has undergone several significant maintenance and improvement works over the years, including a comprehensive electrical upgrade in 2006 that added multiple electrical outlets, lighting fixtures, and circuits throughout the building, and a complete reroofing project in 2017 costing $8,880. The building has also experienced some concerning incidents, most notably a cluster of complaints in early 2023 alleging illegal painting and electrical repairs, dumping, and fraudulent property transfers, though these issues were marked as not active by April 2023.
An earlier serious incident from 1999 involved hazardous materials in the garage that were resolved by April 2000. The property has been the subject of numerous parking-related complaints in recent years, particularly between 2022 and 2024, with multiple citations issued for sidewalk parking and driveway blocking. Between October 2023 and November 2024 alone, there were at least five documented cases of illegal parking, with some resulting in citations.
While parking enforcement has addressed these violations, they suggest an ongoing issue with parking in the area. Temporary issues have included street cleaning matters, such as a Christmas tree pickup in 2023 and loose garbage removal in 2019, as well as a flickering streetlight in 2017. The building's maintenance history shows regular upkeep, with the 2017 reroofing and 2006 electrical upgrades indicating investment in the property's infrastructure. However, the recent complaints regarding unauthorized modifications in 2023 deserve attention, though their current "not active" status may indicate resolution or lack of further enforcement actions.
