35-37 Castillo St, San Francisco, CA 94134

The two-unit residential building at 35-37 Castillo Street in Visitacion Valley, owned by the Bertram Family Trust, was constructed in 1948 as a two-story flats and duplex structure. The property has undergone several significant infrastructure improvements, most notably in March 2009 when substantial electrical upgrades were completed on the first floor, including the transition from fuses to breakers, installation of two meters, and the addition of new electrical panels with varying capacities.

Earlier maintenance work included reroofing undertaken in 1997, though this permit has since expired. More recent concerns at the property warrant attention, particularly two incidents in August 2024 involving public health and mold/mildew issues, both of which were accepted for investigation.

The building's environment has experienced multiple parking-related disturbances between 2021-2022, with several reports of double parking and illegal parking, though these issues were primarily street-related and have since been logged for city data collection purposes. While these parking incidents don't directly affect the building's habitability, they do reflect some neighborhood challenges. The property's electrical system improvements from 2009, including the installation of modern electrical infrastructure, suggest efforts to maintain and upgrade essential systems, though the status of some permits from this period is noted as expired.
