273-275 San Carlos St, San Francisco, CA 94110

The two-unit multi-family residential building at 273-275 San Carlos Street in the Inner Mission, built in 1910, has experienced several significant maintenance and compliance issues over the past several years. Most notably, in 2018-2019, there were multiple health and safety violations including mold/mildew on ceilings and walls, damaged walls and ceilings, broken windows, plumbing issues, and fire safety concerns, all of which were addressed by October 2018 through necessary repairs and upgrades. The property underwent several window replacements between 2005-2019, including a 2019 project to repair a single window facing the rear yard at a cost of $1,108.

Roof maintenance has also been a recurring issue, with repairs needed in 2019 for a leak above a bay window, which was initially reported as causing water damage and potential mold growth. The building has been equipped with solar panels since 2005, and electrical upgrades have included the installation of additional plugs in 2003. A notable ongoing concern involves allegations of an unauthorized dwelling unit on the property, with investigations and enforcement actions initiated between 2016-2020, though this matter appears to currently be on hold with a Notice of Proposed Foreclosure issued in late 2020.

Recent activity at the property has primarily consisted of maintenance and cleaning issues, as evidenced by numerous 311 calls in late 2024 and early 2025 regarding garbage, debris, and water leak issues, though these are typically street-level concerns not directly related to building conditions. The building's permit history shows regular maintenance and improvement work, including window replacements, solar panel installations, and various repairs to maintain compliance with safety regulations. While the building experienced significant compliance issues in 2018-2019, these were addressed through appropriate permits and inspections, though the ongoing unauthorized unit investigation suggests some historical compliance issues may persist.
