4000-4004 Mission St, San Francisco, CA 94112

The property at 4000-4004 Mission Street in Bernal Heights is a mixed-use building constructed in 1910, containing two residential units and commercial space, currently owned by Arcenio Co LLC. The building has undergone several significant infrastructure improvements in recent years, including a comprehensive roof replacement in 2021 ($18,500) following a 2020 water damage incident in the commercial space, which also required bathroom repairs and electrical upgrades ($15,000).

The property has experienced consistent maintenance of essential systems, with plumbing and electrical upgrades completed in 2021, including a main service upgrade and multiple system repairs between 2017-2021. The building has a documented history of compliance issues, most notably in 2015-2018 when it was cited for failing to maintain proper registration and exterior upkeep under the Vacant Building Ordinance, though these violations were ultimately abated by December 2018. Historical records from 2006 indicate a serious over-occupancy situation involving 15 individuals in the garage area, which was resolved within one month.

Recent months have seen numerous reports of overflowing city garbage cans in January 2025, though these appear to be municipal service issues rather than building-specific problems. The property experienced one fire-related incident in November 2020 involving a malfunctioning smoke detector, which resulted in a violation that was subsequently abated. Regular maintenance records show attention to various systems including sewer repairs, gas line upgrades, and exterior lighting installations, suggesting ongoing investment in the building's infrastructure.
