1648-1650 Beach St, San Francisco, CA 94123

The duplex at 1648-1650 Beach Street, located in San Francisco's Marina neighborhood, is a two-unit residential building owned by Stephen and Christina Carroll. Built in 1938, this two-story flats and duplex structure has undergone several significant renovations over the past few decades. The most substantial recent improvement occurred in 2014, when an extensive renovation project valued at $98,600 was completed, including infilling of the second floor courtyard, deck expansion, window and door modifications, interior remodeling, and the installation of multiple new skylights on both the second and third floors.

That same year, comprehensive electrical work was performed including a complete re-wire of both units and the installation of new gas forced air furnace systems, followed by a 200-amp service upgrade in 2015. Additional renovations included basement remodeling in 2000, kitchen updates in 1997, and bathroom improvements. The building's recent maintenance record shows proper attention to infrastructure, with the completion of various plumbing inspections, including shower pan inspections and the installation of new gas lines for furnaces and fireplaces in 2014.

The property has experienced recurring issues with driveway blocking, with multiple parking enforcement calls in recent years (2021-2024), and had a period of waste management compliance issues in late 2021. While these external matters do not directly affect the building's condition, they may impact resident convenience. The most recent infrastructure improvements and consistent pattern of building maintenance, including proper permit completions and inspections, suggest active management of the property's physical systems and adherence to regulatory requirements.
