The property at 3790-3792 21st Street is a two-unit residential building located in the Eureka Valley/Dolores Heights neighborhood, owned by the Michael J Niland Trust and constructed in 1929. The building has undergone significant renovations and faced numerous inspection and compliance challenges in recent years. Most notably, in 2023, there were multiple permit revisions to address construction violations and legalize unapproved changes from previous construction work, with particular attention to window modifications at property lines.

The building's renovation history includes extensive work in 2018-2019, such as a full electrical upgrade, installation of a fire sprinkler system, and various interior reconfigurations across multiple floors. The property has been the subject of multiple construction-related complaints between 2018-2022, including concerns about unauthorized work, construction during shelter-in-place orders, and issues with neighboring property lines and construction methods. There is currently a significant Planning application under review regarding the supposed de facto demolition of the original structure, which the Planning Commission is evaluating in connection with Enforcement Case No.
