402-404 Cortland Ave, San Francisco, CA 94110

The property at 402-404 Cortland Ave in Bernal Heights is a two-story multi-family residential building with storefront space, containing two units, and was built in 1900. The building's maintenance history shows several significant improvements, including a complete reroofing project in 2012 costing $13,450, window replacements in 1998, an electrical upgrade to a 180-amp underground system in 2005, and various renovations in the 1990s. However, the building has faced serious regulatory and safety concerns in recent years, with the most pressing issue currently being an active complaint filed in September 2024 regarding an unauthorized conversion to a karate gym in the commercial space.

Of particular concern is a pattern of unauthorized modifications and safety violations, including multiple complaints about an illegal attic unit between 2015-2019, where an unauthorized kitchen, inadequate bathroom facilities, lack of windows, and improper egress conditions were reported. Historical records show previous attempts at construction modifications in the 1980s, including structural alterations and electrical work, though some permits were withdrawn or expired. The property has experienced various maintenance and infrastructure issues, as evidenced by multiple 311 calls between 2022-2024, including instances of garbage overflow, sewage backup, and general street cleaning needs.

While many recent garbage-related complaints have been resolved promptly, they indicate ongoing waste management challenges in the area. The building's age and history suggest regular maintenance has been performed over the years, including roofing, siding, and window improvements, though the appearance of recent illegal modifications raises concerns about proper oversight of building systems and safety compliance. The property is currently owned by the Ken & Amy Shelf Revocable Trust.
