1604 Treat Ave, San Francisco, CA 94110

The property at 1604 Treat Avenue is a two-unit, two-story multi-family residential building located in Bernal Heights, constructed in 1908. The most recent significant event involved repairs to the building's front siding in September 2023, following damage caused by a vehicle, though this work was non-structural and cost approximately $5,000. The building underwent a major transformation between 2018-2019 with the conversion of an existing storage area into an ADU (Accessory Dwelling Unit), which included comprehensive plumbing and electrical work, new kitchen and bathroom installations, and radiant heating systems, costing around $95,000.

Other notable improvements include a complete reroofing project in 2019 ($10,600), a kitchen and dining room remodel in 2008 ($36,000), and various infrastructure improvements such as a foundation drain installation in 1995 and garage repairs in 2003. The building's maintenance history shows regular upkeep of essential systems, including a P-trap replacement in 2022 and multiple plumbing and electrical updates, particularly during the ADU conversion period. The property has experienced multiple incidents of abandoned vehicles in the vicinity, with ten reports between October 2024 and December 2024, though none of these incidents directly impacted the property itself.

The building appears to be well-maintained, with all permitted work completed to code and no recorded safety violations or resident complaints in recent years. The ownership group, Cheryl M. and Christopher M. Porro, appears committed to maintaining and upgrading the property, as evidenced by their regular investment in improvements and prompt response to maintenance issues.
