228-232 Collingwood St, San Francisco, CA 94114

The property at 228-232 Collingwood Street is a two-unit, two-story multi-family residential building constructed in 1926, currently owned by Nicole Tseng. The building has undergone significant recent improvements, most notably the comprehensive installation of a fire sprinkler system in 2022-2023, with the most recent work involving a sprinkler monitoring system completed in October 2023 at a cost of $5,406.

The property has seen substantial modernization efforts, including the installation of two solar systems in February 2023 (totaling 4.51 kW), upgrading the electrical service to 400A in May 2022, and the addition of three ducted heat pumps for the duplex in 2021-2022. Major interior renovations have included bathroom and laundry room modifications, window installations, and the construction of additional habitable spaces, particularly the addition of a new dwelling unit in the rear yard area, which required specific variances and planning approvals. The building's recent history shows active maintenance and upgrading of essential systems, including plumbing improvements with the installation of new kitchen, bathroom, and laundry facilities, as well as heat pump water heaters in 2020.

The property has maintained compliance with safety regulations through the systematic installation of fire safety systems, including the conversion of the entire building to accommodate sprinklers. While there have been some municipal service calls recorded, these have primarily related to external issues like sidewalk conditions and parking concerns rather than building-specific problems. The property's recent improvements, particularly the fire safety system installations and energy-efficient upgrades, suggest a commitment to maintaining and improving the building's infrastructure and safety systems.
