1490 Clayton St, San Francisco, CA 94114

The property at 1490 Clayton Street is a three-story, two-unit multi-family residential building located in the Corona Heights neighborhood, constructed in 1982 and currently owned by the Helga F Poulsen Trust. The building's documented history shows several maintenance and infrastructure improvements, including a roofing project completed in 1998 and a significant electrical upgrade in 2003 that involved converting to underground service with two meters and installing a 125-amp system.

The property underwent a two-lot split conversion in its early history, resulting in the creation of a duplex structure with a total of 2,609 square feet on a 1,387-square-foot lot. In recent years, the property has experienced several maintenance and cleanliness issues in its immediate vicinity, with multiple reports of graffiti (most recently in April 2024), and recurring problems with garbage and debris on surrounding sidewalks and streets throughout 2023-2024.

There was also a water-related incident in February 2024 involving main break repairs in the area, which affected the building's water service. The property has maintained compliance with necessary permits and inspections over the years, with records showing completed electrical work and routine upkeep, though the 1998 roofing permit has since expired. The building's ownership and structural modifications appear to be properly documented through city planning records, which confirm its legal status as a duplex residential structure.
