2506-2508 25th St, San Francisco, CA 94110

The two-unit residential building at 2506-2508 25th Street, owned by Ralph Nunez, is a two-story flats and duplex structure built in 1908 in San Francisco's Inner Mission neighborhood. The property has undergone several maintenance and improvement projects over the years, including roof replacement in 2001 ($8,000), vinyl siding installation in 2000 ($8,750), stair rebuilding in 1994, and most recently, water heater upgrades in 2020 to bring the systems up to code. However, the building has a concerning history of unpermitted work and safety issues.

Most recent complaints from August 2024 reported unauthorized demolition work in the garage affecting the slab and foundation, as well as similar concerns from June 2024 related to vacant unit remodeling activity. Previous violations include exposed electrical wiring hanging from a tree (2020), unauthorized roof and deck work (2020), and illegal water heater installation (2019). The property has also faced multiple complaints about construction activity and noise, including an illegal guest room conversion complaint in 2018 and a potentially problematic roof construction issue in 1998 that reportedly caused water leaks.

Recent maintenance issues have been documented through 311 calls, including sidewalk pavement defects (December 2024), graffiti removal (July 2024), and various garbage and debris complaints. The building's documented improvements, such as the 2020 water heater upgrade, suggest some maintenance attention, but the pattern of unpermitted work and related safety concerns raises significant questions about ongoing compliance with building codes and safety standards. The most recent planning record from 2016 indicates a short-term rental activity investigation that found no violations at that time, though this was several years ago and may not reflect current usage.
