477-479 Collingwood St, San Francisco, CA 94114

The two-unit residential building at 477-479 Collingwood Street, owned by Garrett Tyler Goff, has a documented history of maintenance primarily focused on addressing dry rot issues. Most recently, in 2019, repairs were completed on the front elevation, including dry rot remediation and window reinstallation at a cost of $6,000. A more extensive repair project was undertaken in 2018 at the rear of the building, involving stucco removal, framing and sheathing repairs, and door/window replacements, costing $25,000.

The building, constructed in 1951 and classified as a two-story flats/duplex structure, is currently undergoing significant electrical system upgrades, with permits issued in late 2024 for solar panel installation and load center replacements. There have been multiple instances of dry rot repairs and window replacements documented between 2006-2019, suggesting ongoing moisture management challenges. The property has experienced several maintenance and infrastructure issues more recently, including multiple reports of sidewalk parking violations in 2022, tree damage cases in 2021, and sidewalk defects identified in 2021.

Planning records show a controversial proposal to legalize a third dwelling unit in the basement without parking, though the current status was marked as "Closed - Approved". A significant tenant buyout of $42,500 was executed in May 2024, involving one tenant. The electrical improvements currently underway include the installation of 23 roof-mounted solar PV modules and battery storage systems, representing a transition towards renewable energy. The building has a notable history of addressing moisture-related issues, as evidenced by the pattern of dry rot repairs and window replacements over the years.
