231-233 11th Ave, San Francisco, CA 94118

The property at 231-233 11th Avenue in San Francisco's Inner Richmond neighborhood is a two-unit, two-story residential building constructed in 1910, currently owned by Do Good LLC. The building has undergone significant renovations and safety upgrades over the past several years, most notably the installation of a comprehensive fire safety system in 2021-2023 that includes a new sprinkler system, fire alarm control unit, wireless communicator, smoke detectors, and manual pull stations, with associated costs totaling nearly $50,000.

In 2022, the building underwent substantial interior modifications including kitchen and bathroom reconfigurations, window replacements, and the addition of a patio door. The property also underwent major structural work in 2021-2022, including the addition of roof dormers and conversion of attic space into habitable areas. The building has faced some challenges, most notably an interior demolition without proper permits in 2020 that resulted in violation notices, though this issue was eventually abated in late 2024.

Recent plumbing updates include sewer and house trap replacement and new gas line installations in 2023-2024, while electrical improvements from 2021 include complete rewiring of both units with new panels and extensive lighting, appliance, and safety system installations. Historical records from the late 1990s show previous maintenance issues with garage doors, water heater, and refrigerator, but these were promptly addressed. The building's recent maintenance history appears generally positive, with the most recent work focusing on plumbing infrastructure improvements and continued maintenance of fire safety systems.
