251-253 9th Ave, San Francisco, CA 94118

The two-unit residential building at 251-253 9th Avenue in the Inner Richmond, owned by 251 9th Ave LLC, has undergone significant improvements since 2019, including substantial basement renovations adding new living spaces. The building, constructed in 1902, received major upgrades in 2019 including the addition of new bedrooms and bathrooms, kitchen reconfigurations, window replacements, and deck restorations due to dry rot, with associated costs totaling over $286,000.

Infrastructure improvements included new plumbing systems for both units, installation of two gas furnaces, new electrical wiring, and a complete sewer line replacement in 2017. The property has a history of maintaining safety systems, with several smoke detector and alarm system activations recorded, though these incidents were primarily false alarms or system malfunctions with no injuries reported.

The building underwent a routine inspection in June 2006, which resulted in multiple violations related to interior surfaces, fire safety, plumbing, electrical systems, and smoke detection, though all these violations were abated by June 16, 2006. Recent maintenance and service records show periodic issues with garbage and debris management in the vicinity of the property, with multiple 311 calls between 2017 and 2025 regarding cleaning needs, though these are primarily street-related issues rather than building-specific concerns. The property has maintained an active development and maintenance schedule, with all major improvement permits from 2019 marked as complete, including comprehensive updates to both residential units and common areas.
