203 Prospect Ave, San Francisco, CA 94110

203 Prospect Avenue is a three-unit multi-family residential building constructed in 1905 in the Bernal Heights neighborhood, currently owned by the Kellerman Family Trust since 1993. The property has undergone numerous renovations and maintenance work over the years, with significant improvements made between 2010 and 2012 including a ground floor kitchen and bath remodeling (completed) costing $18,276, installation of a washer/dryer on the third floor, and deck railing repairs. More recent issues involve two complaints from July 2019 regarding improper lead paint removal and containment, though these complaints are now listed as not active.

The building has had some maintenance challenges, with multiple sewer-related incidents reported in late 2023 and October 2024, suggesting ongoing plumbing system issues. There were also several building violations noted in 2011 regarding safety concerns, including the need for handrails on stairways, water heater safety modifications, and fire escape access, all of which were eventually abated. The most recent permitting activity observed was a street space permit issued in July 2019, and there was a significant hazardous condition fire incident recorded, though no civilian injuries were reported.

The property's maintenance history shows regular upkeep and modernization efforts, including multiple kitchen and bathroom upgrades across different units, currently maintaining three residential units on three stories. While some historical violations and complaints have been resolved, the building has experienced recurring issues with lead paint management, most recently in 2019, and periodic sewer system problems as evidenced by recent 311 calls. The building's infrastructure improvements and periodic violations suggest ongoing attention to both safety compliance and modernization, though the recent plumbing issues indicate some persistent maintenance challenges.
