28 Cortland Ave, San Francisco, CA 94110

The two-unit residential building at 28 Cortland Ave in Bernal Heights, owned by Hong Warren Wei-shen, was constructed in 1951 as a single-story flats and duplex structure. The property's maintenance and infrastructure history shows several significant system upgrades and repairs, including a successful house trap replacement in 2012, an attempted but ultimately cancelled electrical service upgrade in 2007 that would have installed multiple meters, and an expired gas houseline extension permit from 2011.

A street space and sidewalk permit was issued in February 2012. Recent months have seen multiple service requests and incidents affecting the property and its surroundings, with the most pressing concerns being ongoing issues with tree roots damaging the sidewalk, as reported in both February and October 2024.

There has been consistent parking enforcement activity in the vicinity, with three documented cases of illegally parked vehicles between December 2023 and April 2024, including citations for parking on sidewalks and blocking driveways. Additional neighborhood maintenance issues have been reported through 311 calls, including a shared spaces violation regarding waste management in August 2023, general cleaning needs in February 2024, and a case of damaged tree vandalism that was resolved. While these incidents primarily relate to the building's immediate environment rather than the structure itself, they indicate ongoing challenges with local infrastructure and maintenance.
