1023-1025 Carolina St, San Francisco, CA 94107

The property at 1023-1025 Carolina Street is a two-unit, two-story multi-family residential building located in Potrero Hill, built in 1976 and currently owned by the Joseph V Mersol Living Trust. The building has undergone several significant improvements in recent years, most notably a comprehensive upgrade in 2018 that included the installation of a solar panel system with 12 roof-mounted PV modules (4.14 kW total rating) and a Tesla battery backup system with two batteries.

During the same period, one bathroom was remodeled with new fixtures, including a tub and vanity, along with associated plumbing and electrical updates. The building has received consistent maintenance attention, with roof work (reroofing), window replacements, and exterior maintenance completed between 2012 and 2018, including the installation of eight new vinyl windows across two separate permits. The property underwent an important administrative process in 2017 to document its legal use as a three-story building with two residential units, including a ground floor garage, following a historical permit issue from 1976.

The building's infrastructure improvements also include electrical upgrades, with proper documentation of all work through corresponding permits. Recent activity at the property includes several parking-related complaints and one noise complaint in 2024, though these do not directly impact the building's condition or safety. The property appears to be properly maintained, with regular updates to both safety and efficiency systems, including solar power and battery backup, while maintaining compliance with all necessary permits and regulations.
