407-409 Cornwall St, San Francisco, CA 94118

The three-unit multi-family residential building at 407-409 Cornwall Street in the Inner Richmond, owned by Jan Nordmann, is a two-story flats and duplex structure built in 1902. The property has undergone several significant improvements over the past decade, most notably a comprehensive renovation in 2012 that included $16,000 worth of work focusing on kitchen and bathroom updates on the second floor, including plumbing fixture replacements and electrical upgrades. This renovation also featured the installation of new electrical service with 200-amp capability, kitchen appliance installations (including a dishwasher, garbage disposal, microwave, and range), and bathroom fixture updates.

In 2013, four street-facing windows were replaced with wood-clad versions, though one bedroom window was noted as having existing non-conforming egress issues. Earlier records from 1987 show repair work was needed to address fungus damage. Recent activities around the property have primarily involved external maintenance issues, with recurring reports of graffiti on the mailbox between 2020 and 2023, most recently in June and July 2023.

The building has experienced some infrastructure challenges, including a sewage backup incident in January 2022 and a flooding situation in October 2020, both involving the street infrastructure. Several 311 calls between 2020 and 2022 have been logged regarding street cleaning needs and garbage concerns near the property. While most maintenance issues appear to have been resolved promptly, the recurring graffiti on the mailbox and the two documented sewer-related incidents are noteworthy from a resident experience perspective.
