1-5 Corbett Ave, San Francisco, CA 94114

This three-story, three-unit multi-family residential building located at 1-5 Corbett Avenue in Corona Heights, owned by the Placida Chavez Trust, has a complex history regarding its unit configuration and maintenance. Built in 1965, the building has undergone several significant improvements, including a reroofing project in 2015 costing $11,500, and structural repairs in 2004 that addressed water damage to the stucco and framing at the front of the building.

A voluntary seismic upgrade was attempted in 1998, installing steel elements for improved safety, though this permit expired. The building's permit history shows multiple attempts to address unauthorized unit modifications, with cancelled and withdrawn permits relating to the legalization of additional dwelling units, including a 2017 proposal to legalize an in-law unit and a 2023 project to legalize a second-floor unit with two bedrooms, two baths, kitchen, and office space. The property has been the subject of various complaints and inspections, most notably regarding unauthorized unit conversions, with a complaint filed in 2005 about a possible conversion from two to four units that remained active until 2012.

Recent activity at the property has generated numerous 311 calls (between 2023-2024) primarily related to street cleanliness issues including garbage, debris, and graffiti, though these external maintenance matters do not directly reflect on the building's internal conditions. The building's unit configuration and legalization efforts have been a recurring theme in its history, with multiple withdrawn or cancelled permits over the years seeking to address this issue. The property has maintained basic safety improvements over time, with records showing attention to roofing, seismic safety, and some interior modifications, though the status of many permit applications suggests either incomplete work or changes in project scope.
