141-143 San Carlos St, San Francisco, CA 94110

The two-unit residential building at 141-143 San Carlos Street, located in San Francisco's Inner Mission neighborhood, is an early 1900s flats and duplex structure owned by Bruce Johnson and Brooke Kuhn. The building has undergone several significant improvements over the past decade, with the most recent major work being a complete roof replacement in 2021 costing $8,900 and the installation of a new furnace in 2019.

Between 2015 and 2016, substantial interior renovations were completed, including a full kitchen and bathroom remodel (costing $60,000) with associated electrical and plumbing upgrades to meet Title 24 compliance, and another bathroom renovation project in 2016 costing $24,000. Earlier structural maintenance included the installation of four footings under existing porch posts and replacement of both front and rear stairs in 2001.

The building has had one building code violation in 2009 regarding an exterior wood utility ladder, which was promptly resolved within a month. Recent building activity has primarily consisted of maintenance and infrastructure improvements rather than addressing any major safety concerns. The property has experienced multiple incidents related to street conditions outside the building in 2024, with several reports of garbage and debris (including instances of human waste) between June and October 2024, along with some parking enforcement issues, though these external matters do not directly reflect on the building's condition or management.
