150-152 Hartford St, San Francisco, CA 94114

The two-unit residential building at 150-152 Hartford Street, constructed in 1885, has undergone significant renovations and safety upgrades in recent years. The most substantial work occurred between 2019-2021, including the addition of a new 1,236 sq ft ground floor apartment (valued at $300,000) containing three bedrooms and two bathrooms, followed by comprehensive remodels of the existing units featuring relocated kitchens and bathrooms, added bathrooms, and window modifications.

The property underwent major safety improvements with the installation of a new fire sprinkler system ($18,125) for the ground floor ADU in 2020, followed by a fire alarm system installation in 2021 that included monitoring features. The building's infrastructure was thoroughly updated, including a new 300A electrical service installation for three units and complete electrical rewiring of both residential units, with all work completed in accordance with modern safety standards. The property has maintained regular upkeep of essential systems, including furnace installations and comprehensive plumbing work to support modern amenities throughout both units.

While the building's renovation and safety upgrade work has generally been completed successfully, there was one building complaint filed in June 2021 regarding the installation of new windows lacking the required "ogee" detail per San Francisco's historic replacement window code. Recent 311 calls from 2022-2024, though not directly related to the building's condition, indicate ongoing street maintenance and environmental challenges in the immediate vicinity, including reports of debris, tree damage, and hazardous materials on the street, with the most recent concerns being about a dead tree (reported December 2024). These external factors, while not directly affecting the building's structure or systems, do impact the overall neighborhood environment.
