900 Potrero Ave, San Francisco, CA 94110

The two-story, 8-unit multi-family residential building at 900 Potrero Avenue, constructed in 1975 and currently owned by 525 Howard LLC, has undergone several significant improvements and faced some noteworthy incidents over its recent history. Most prominently, in early 2018, there were substantial renovation efforts including the replacement of all 56 windows with Marvin Integrity Ultrex fiberglass windows ($28,000) and a proposed addition of 5 new units consisting of 2 one-bedroom and 3 studio apartments ($300,000).

The building has experienced multiple instances of vehicle-related damage, notably a 2013 incident involving the northeast corner that required repairs costing $14,000, following a January 2013 violation notice. Historical records show earlier repairs including garage door jamb restoration in 1997 and wall repairs in 1993. Recent activity at the property has included multiple 311 calls in early 2025 regarding garbage and debris, with eight separate reports of overflowing city garbage cans between December 2024 and January 2025, suggesting ongoing waste management challenges in the immediate vicinity.

The building's maintenance history shows regular attention to structural and cosmetic elements, including a 2012 project to replace broken shingles ($4,000). The property underwent routine safety inspections in 2015, with no active violations noted in the recent record. Planning records indicate various proposals for the building, including a withdrawn variance request for adding five new accessory dwelling units (ADUs) and multiple permits related to window replacement and other improvements, demonstrating an ongoing commitment to property maintenance and upgrades by the ownership group.
