2271-2275 Mission St, San Francisco, CA 94110

The three-story mixed-use building at 2271-2275 Mission Street, owned by On Lam Trust, was constructed in 1907 and contains 4 residential units with ground-floor commercial space. The property has undergone several significant improvements in recent years, most notably during 2018-2019 when major renovations were completed including the addition of bathrooms, kitchen and bathroom remodels, and extensive electrical upgrades including new fixtures, appliances, and smoke detectors across all units.

More recent activity includes a 2023 permit related to the commercial address and multiple maintenance and improvement projects. The building has experienced recurring plumbing issues, with the most recent sewage-related problems reported in early 2025, following similar complaints from 2013. Historical records show a cluster of building code violations documented in 2002, primarily related to safety features such as smoke detectors, security, and building maintenance, though these were abated by 2003.

The property has had multiple fire safety inspections with some violations noted between 2005 and 2022, including blocked exits and shared space concerns, though most were promptly corrected. Recent 311 calls indicate ongoing maintenance needs in the immediate vicinity, though related directly to the building's systems have been relatively minimal since the major renovations. While the building has had various complaints and violations throughout its history, many have been addressed through regular maintenance and repairs, with the most recent significant work focusing on infrastructure updates and safety systems.
