597-599 2nd Ave, San Francisco, CA 94118

The two-unit residential building at 597-599 2nd Avenue in the Inner Richmond, constructed in 1909 and currently owned by ACDAN MARIA A TRUSTEE, has undergone several significant improvements and maintenance work over recent years. Most notably, between 2020 and 2022, the property received substantial upgrades including window replacements (both street-facing and rear windows), voluntary seismic strengthening, electrical rewiring (including removal of knob and tube wiring), and foundation work involving pier footings and posts at the north property line.

The building's mechanical systems have also been modernized, with new furnaces installed in 2017 and electrical panels upgraded to a 200-amp multi-meter system with 100-amp panels. Recent activity at the property primarily consists of waste management issues, with multiple reports of garbage and debris in the vicinity between October 2024 and January 2025, though these are external to the building itself.

An accessory dwelling unit (ADU) addition was proposed in 2020 at an estimated cost of $120,000, but this permit was ultimately cancelled. The building's maintenance history shows regular upkeep, including repairs to wood siding and trim due to dry rot in 2019, and foundation-related work in 2021, suggesting ongoing attention to both structural and aesthetic maintenance. The property has undergone several electrical system upgrades since 2003, including multiple circuit installations and electrical system improvements, indicating a progressive approach to updating the building's infrastructure.
