939 Clayton St, San Francisco, CA 94117

The three-story, two-unit multi-family residential building at 939 Clayton Street in the Parnassus/Ashbury Heights neighborhood, owned by Mccoy Waukeen, has a history spanning several decades since its construction in 1965. The building underwent significant interior improvements in 1998, including bathroom remodels and kitchen renovations, and received a new roof in 1992. More recently, there have been multiple concerning issues regarding unpermitted construction activity, particularly related to a roof deck installation.

Complaints were filed in February 2022 and November 2018 regarding unauthorized roof deck construction, including the installation of a hot tub and reported unsafe conditions. A plumbing permit from 2014 documented the replacement of a 48-gallon water heater. Additionally, there has been a significant pattern of parking violations in the vicinity of the property in 2024, with at least ten complaints regarding blocked driveways and sidewalk parking, resulting in several citations being issued.

The building's recent maintenance history shows some activity, with a streetspace permit issued in 2018, though the current status remains ambiguous. The property continues to experience recurring issues with illegal parking, particularly evident in 2024 with multiple citations for blocked driveways and sidewalk parking. While the documented building improvements from the 1990s and the 2014 water heater replacement indicate some level of maintenance, the lack of recent permitted major renovations and the ongoing concerns about unpermitted construction from 2018-2022 warrant attention. The building's exposure to potentially hazardous construction practices, particularly concerning stone countertop work with harsh chemicals on public property as reported in 2022, represents a notable safety concern.
