3145-3147 Balboa St, San Francisco, CA 94121

The two-unit residential building at 3145-3147 Balboa Street in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1955, currently owned by Mackey Christian & Leung Ju. The property has undergone several significant improvements over the past decade, with the most recent major renovation taking place in 2018, which included the addition of a half-bath and game room on the first floor, along with the replacement of two rear vinyl windows and a patio door, with a total project cost of $42,000.

Prior to that, in 2015, substantial updates were completed to the building, including kitchen and bathroom remodeling ($23,000), electrical upgrades with the installation of a new 100-amp panel in the owner unit, and various new fixtures, appliances, and three smoke detectors. The building's maintenance and improvement records show regular attention to infrastructure, with plumbing systems receiving upgrades as needed, including the installation of the new half-bath in 2018. The property's external environment and street-facing areas have experienced typical urban challenges, with several 311 calls recorded between 2017 and 2023, primarily relating to street and sidewalk cleaning, loose garbage, illegal postings, and noise complaints.

Notably, two excessive noise reports were filed in July 2019, and there were two instances of street cleaning issues reported in 2021 and 2023, all of which were resolved through normal city processes. While these incidents reflect typical urban neighborhood concerns, none appear to indicate any structural or safety issues with the building itself. The property's permit and improvement history suggests regular maintenance and upgrading of both the interior and exterior spaces, with particular attention paid to improving resident amenities and building systems over the past decade.
