2448-2454 15th St, San Francisco, CA 94114

The three-story, six-unit multi-family residential building at 2448-2454 15th Street in Corona Heights, owned by Thomas A Barth Revocable Tr, was built in 1907 and has undergone several significant renovations and faced numerous maintenance challenges over recent years. Most notably, the building completed a mandatory seismic soft-story retrofit in 2016, demonstrating compliance with current safety standards. Recent improvements include a substantial kitchen and bathroom renovation in 2022 ($65,000), installation of a new furnace and related systems, and electrical upgrades including a 40-amp subpanel and new lighting systems.

However, the property has also experienced serious maintenance issues, particularly between 2017-2019, with multiple complaints regarding insufficient heating, mold, electrical problems, and insect/rodent infestations. In late 2021, there were concerns about unauthorized construction work potentially involving lead hazards in an occupied unit. The building's maintenance history shows a pattern of addressing both routine and urgent repairs, including multiple plumbing and electrical upgrades, though several permits issued during 2019-2022 expired without recorded completion.

A notable cluster of violations was documented in late 2017, including issues with fire safety equipment and building code compliance, though these were abated by early 2018. The property has maintained its basic structural integrity through soft-story retrofit completion and various system upgrades, but the persistence of some maintenance issues, such as the unaddressed heating problems from 2019, suggests ongoing challenges with building systems and unit maintenance. Recent 311 calls (2024) indicate some persistent exterior maintenance issues, though these are typically addressed promptly by city services.
