39-41 Castillo St, San Francisco, CA 94134

The two-unit residential building at 39-41 Castillo Street in Visitacion Valley, owned by Ma Lloyd & Duong Yen-xuan, is a two-story flats and duplex structure built in 1949. The property has experienced several notable incidents over the past decade.

A 2019 attempt to install a solar system with 15 PV modules was initiated but ultimately resulted in a cancelled permit. A significant housing concern was raised in 2011 when a complaint was filed regarding an illegal unit in the garage which was reportedly impacting parking, though this case is currently listed as not active.

More recently, there have been multiple parking-related issues in the vicinity of the property, including complaints in 2024 and 2023 regarding vehicles blocking driveways and illegal parking, both of which were either unable to be validated or the vehicles could not be located when officers responded. The building experienced some infrastructure challenges, including a sewage backup incident in March 2019 that was addressed and resolved by PUC Sewer Operations. Additionally, in May 2020, there was an environmental health complaint filed through the Department of Public Health, though the specific details of this complaint are not provided in the records.
