4145-4147 19th St, San Francisco, CA 94114

The two-unit, two-story multi-family residential building located at 4145-4147 19th Street in the Eureka Valley/Dolores Heights neighborhood is currently owned by the Boyd M Swartz Revocable Trust 10 and dates back to 1900. The property has undergone several significant modifications and improvements over the years, with the most recent activity being a $1,000 barrier remediation project filed in September 2023 to comply with the ABE program, including the installation of exterior signage and a customer assistance buzzer.

The building's maintenance history includes street space and sidewalk repairs in 2009, window replacement work in 1998, and water service line replacement that same year. In early 2025, the property experienced water-related issues, with two PUC Water Department calls regarding leaks in January, though one was determined to be groundwater-related. There has been a notable pattern of street cleaning and maintenance calls in the surrounding area, particularly in late 2024, with multiple reports of garbage and debris needing attention, including incidents involving abandoned furniture and a Christmas tree.

The building's regulatory history shows earlier efforts toward zoning reclassification, with proposals to rezone from RH-3 to Castro NCD or NC-1 status, and various planning records related to ABE compliance. An electrical alteration permit was filed in 1984, though that application was ultimately cancelled. The property's permit and service call history suggests ongoing maintenance and compliance efforts, with recent focus on accessibility improvements and environmental compliance.
