342-344 San Carlos St, San Francisco, CA 94110

The property at 342-344 San Carlos Street is a two-unit, two-story residential building located in the Inner Mission. Built in 1900 and owned by the Donna K Theisen Revocable Trust, this flats/duplex structure has undergone several significant renovations over the past two decades.

The building's most critical historical period was between late 2003 and 2004, when multiple building violations were recorded and addressed, including issues with damaged ceilings, electrical concerns (including cord wiring and lack of permits), plumbing problems (toilet and sink repairs), heating system deficiencies, mold and mildew presence, and inadequate hot water storage capacity. All these violations were officially abated by June 2, 2004, through various improvements including complete rewiring (installation of lights, switches, receptacles, and circuits), electrical service upgrade to 200 amps, and extensive remodeling of bathrooms and kitchen spaces. More recent improvements to the property include reroofing work completed in 2006.

The building has had no significant building violations or safety concerns on record since 2004, but recent activity from 2023-2024 has primarily consisted of parking enforcement issues, with multiple citations issued for vehicle-related violations including blocking driveways and illegal parking. There was one hoarding complaint filed in August 2024 that was investigated and found to have "No Merit" by October 2024. Additionally, there have been several reports of garbage and debris issues near the property that required intervention by street cleaning services, though these appear to be external clean-up matters rather than building maintenance concerns.
