3472-3474 Pierce St, San Francisco, CA 94123

The two-unit residential building at 3472-3474 Pierce Street in the Marina neighborhood is a two-story flats and duplex structure built in 1927, currently owned by the Marco Lancieri 2013 Trust. The property has undergone several significant improvements over the years, with the most recent substantial renovations occurring in 2020, including an in-kind kitchen remodel ($25,000), full electrical system rewiring with new hardwire smoke detectors installation, sub-panel installation in unit #3474, and plumbing work including kitchen rough-ins and new bathroom fixtures. A major plumbing upgrade was completed in October 2022 with the replacement of the house trap and approximately 40 feet of sewer line.

Earlier improvements include the installation of pocket doors and closet modifications in 2012, and structural improvements in 1989 with mudsill bolting to the foundation. The building's maintenance history shows attention to both systems and safety, with electrical upgrades including additional lighting and outlet installations in 2012, and important structural work such as reroofing (1996) and garage panel leveling (1989). More recent challenges include seven open noise complaints filed in June 2024, indicating possible persistent noise issues affecting resident quality of life.

There have also been three parking-related incidents near the property between September and October 2024, though these were promptly addressed by enforcement officers. A street cleaning issue was resolved in January 2025. The property's maintenance record shows regular upkeep of both unit interiors and building infrastructure, with no documented fire incidents or civilian injuries on record, and only one false fire alarm/call incident noted.
