1817 Lyon St, San Francisco, CA 94115

The multi-family residential building at 1817 Lyon Street in Pacific Heights is a two-story, four-unit apartment structure built in 1900, currently owned by the McGee/Swain Family Trust. The property has undergone several significant maintenance and improvement works over its lifetime, with the most recent being a filed permit in June 2022 for unit #3 to allow for the use of an ILO (In-Law Unit) within the existing legally permitted structure.

The building has received attention to its roofing needs in 1989 and 2007, with both reroofing projects completed at costs of $5,500, and termite repairs were performed in 1995. Historical records also show some interior renovations in 1990 involving bathroom modifications.

The building has undergone several routine housing inspections over the years in 2000, 2008, and 2011, with no active violations noted from these inspections. However, there is an active plumbing-related complaint from 1997 concerning the building's sewer system, which has been documented as having excessive grease issues and connections to neighboring properties through a six-inch clay pipe, requiring multiple instances of snaking and partial replacement of 25 feet of sewer pipe, with the problem recurring despite repairs. The only recent maintenance issue noted was a 311 call in June 2021 regarding illegal postings on street furniture, which was resolved by city cleaning services.
