14-18 Seymour St, San Francisco, CA 94115
The property at 14-18 Seymour Street is a two-unit, two-story multi-family residential building constructed in 1900 in the Western Addition neighborhood, currently owned by Sonia Gioseffi. The building has undergone several significant maintenance and improvement projects over the past decade, with the most substantial recent work being a $25,000 repair of 50% of the front stairs due to wood rot completed in 2021.
Other notable improvements include a sewer lateral replacement and house trap installation in 2019, various plumbing updates in 2011-2012 including new fixtures and a gas furnace installation, and significant exterior work in 2013 including replacement of rear siding and windows. The building experienced some regulatory challenges in late 2011 through early 2012, when multiple complaints were filed regarding suspected unauthorized basement unit modifications and electrical work, though these issues were subsequently addressed and closed. The building's maintenance record shows regular attention to both structural and systems upkeep, with completed electrical rewiring of the apartment and kitchen in 2011, kitchen remodeling projects, and various building permits for necessary repairs.
The property has undergone routine safety inspections, with the most recent one conducted in 2018 by Housing Inspection Services. While there have been several 311 calls regarding the street and sidewalk conditions around the property, including reports of waste and abandoned vehicles, these external issues are not directly related to the building's condition. The building's records indicate compliance with building codes and prompt attention to maintenance needs, with no active building violations on file as of 2023.
