531-535 Frederick St, San Francisco, CA 94117

The three-story multi-family residential building at 531-535 Frederick Street, located in the Parnassus/Ashbury Heights neighborhood, is a 4-unit apartment structure built in 1908 and currently owned by Theresa A. Leung Trustee. The building has undergone several significant renovations and maintenance work over the past few decades, including major structural reinforcement in the early 1990s with foundation anchor bolts installation (1991) and brick support reinforcement for the main stairs (1993).

A comprehensive electrical system upgrade was completed in 2017 with the installation of a new 200-amp service for the entire building (covering 531, 533, and 535 Frederick Street), and a kitchen remodeling project was executed during the same period that included plumbing upgrades and new appliances. A furnace replacement was completed in 2016 for the top floor flat at #535. Recent activity at the property includes a noise complaint in June 2024, which was related to entertainment and subsequently closed.

The building has undergone regular routine housing inspections (2003 and 2008) which were completed without any noted concerns. Service requests through 311 have included several parking enforcement issues between 2018-2020, primarily concerning vehicles blocking driveways, and some waste management concerns in 2023. A tree planting request was submitted in February 2023, though the Department of Public Works indicated they currently lack the resources to fulfill the request, while confirming the area was an empty basin. The property appears to have been well-maintained, with all major systems upgraded or replaced as needed, and no significant health or safety violations on record.
