437-441 Chestnut St, San Francisco, CA 94133

The three-story multi-family residential building at 437-441 Chestnut Street, located in North Beach, was constructed in 1907 and contains 5 units. The property, currently owned by Donald Russo and Margaret Johns, has experienced several significant issues in recent years, particularly concerning an unauthorized structural addition. In May 2021, a complaint was filed regarding a reportedly unstable horizontal addition at the second floor west side of the rear building, which allegedly extended approximately 40 square feet beyond the property line into the neighboring lot and was constructed without proper permits.

This structure raised safety concerns due to substandard support, leading to an active building violation that remains unresolved pending a director's hearing scheduled for January 2025. Following this investigation, permits were filed in 2022 to provide additional structural support to the existing cantilevered bay as required by the San Francisco Department of Building Inspection. The building's maintenance history includes multiple roofing projects, with completed reroofing work done in 2011 (cost: $7,000) and 2019 (cost: $18,000). A sewer lateral replacement was completed in July 2022.

The property has undergone several routine housing inspections over the years, with the most recent one from 2015 still showing as active. Notable infrastructure issues include two sewage backup incidents recorded in August-September 2016. The building area has generated various 311 calls over recent years, primarily related to abandoned vehicles, street cleaning, and a temporary moving sign request in 2013. Recent records show some minor exterior maintenance issues being addressed, including street space renewal in October 2023 and a garbage debris case in December 2024.
