180 Cortland Ave, San Francisco, CA 94110

The property at 180 Cortland Avenue in Bernal Heights is a two-unit, two-story multi-family residential building constructed in 1910, currently owned by Jonathan P & Susan E Walthe. The building has undergone significant renovations over the past several years, with the most recent major work completed in 2023 involving replacement of the house trap and sewer lateral section, along with various plumbing updates.

A substantial redevelopment project was carried out between 2017 and 2019, which included restoring a previously removed ground floor unit, with revisions relocating Unit B from the third floor to the first floor and modifying its layout to include one bedroom, one bath, an office, and kitchen/living areas. The building underwent various infrastructure improvements during this period, including electrical service upgrades with the installation of new 100-amp services, and substantial plumbing work including bathroom and kitchen renovations.

Historical records indicate earlier maintenance work including window replacement (18 windows in 1996) and roofing work in 1995. In recent months (October-November 2024), there have been several municipal service calls related to the property's surroundings, primarily involving graffiti incidents on nearby properties, waste management issues, and parking enforcement matters, though none directly related to the building's structural or safety systems. The property's permit history suggests thorough attention to building systems, with all major recent permits marked as complete, indicating proper follow-through on construction and renovation work.
