1495-1497 25th Ave, San Francisco, CA 94122

The multi-family residential building at 1495-1497 25th Avenue in the Central Sunset neighborhood, owned by Joseph Sun and Mark Denton, is a two-story, three-unit apartment structure built in 1940. The property has undergone several significant improvements and maintenance work over the years, with the most substantial renovation occurring between 2014-2015, when a rear balcony with stairway, concrete hardscape, and new landscaping features were added at a cost of $40,000. During the same period, the lower unit received a kitchen and bathroom remodel, and the building underwent necessary repairs to address stucco removal and dry rot issues, totaling approximately $62,500 in improvements.

Other notable work includes a complete reroofing in 2007 ($14,730) and multiple recent plumbing and electrical upgrades, including the installation of new bathroom fixtures, exterior lighting, and drainage systems. The building has experienced some recent infrastructure challenges, with multiple sewer backup incidents reported between October 2024 and January 2025, all associated with the side sewer vent. There was one building complaint filed in October 2017 regarding unpermitted construction work, though this complaint is listed as not active.

The property had several housing violations in 2002 pertaining to fire safety equipment, gas shutoff tools, and smoke detector requirements, but these were all abated by November 26, 2002. More recent inspections and complaints primarily relate to parking enforcement issues and utility matters. The building's recent maintenance history suggests active management, though the recurring sewer discharge incidents may indicate ongoing infrastructure challenges that require attention.
