3508-3510 26th St, San Francisco, CA 94110

The two-story, six-unit multi-family residential building at 3508-3510 26th Street in San Francisco's Inner Mission, owned by Domenic J. Cannizzaro, has experienced several significant maintenance and safety events since its construction in 1900.

Most notably, there were two instances of unpermitted work in 2019-2021: unauthorized stair replacement work in December 2019 and exterior electrical work in March 2021, both of which resulted in violations that were finally abated in April 2022. The building has undergone several necessary repairs over the years, including step and riser replacement in 2020, back deck dryrot repairs in 2013, and an attempt at reroofing in 2006 (permit expired).

The property has experienced multiple fire alarm activations between 2008 and 2012, though all were determined to be either false alarms, system malfunctions, or unintentional activations, with no civilian injuries reported. While the building's structural maintenance has been addressed through various permits, the lack of proper permits for significant repairs has raised safety concerns. Recent 311 calls in the area (2024-2025) primarily relate to street conditions and sidewalk maintenance, rather than building-specific issues, though there are current openings for graffiti removal on public property noted in January 2025, and several cases of debris and garbage maintenance that have been resolved.
