4017 18th St, San Francisco, CA 94114

The two-unit residential building at 4017 18th Street, owned by Thomas P Rodgers, is a two-story flats and duplex structure built in 1907 in the Eureka Valley/Dolores Heights neighborhood. The property's maintenance history shows relatively regular upkeep, with the most significant recent work being a 2017 roof replacement including cleaning, felt installation, and new shingles at a cost of $10,500. The building underwent several improvements in 1988-89, including kitchen renovations and the installation of exhaust fans, as well as a horizontal addition, all of which were successfully completed.

The property experienced a plumbing issue in 2005 when wastewater lines serving both units' kitchen sinks leaked, though this was promptly resolved within two weeks. The building has faced recurring issues with the adjacent sidewalk infrastructure, with three documented sidewalk defect reports in 2020 and most recently in December 2024, when a collapsed sidewalk was noted. Tree root damage affecting the sidewalk was reported and is currently open as of July 2022.

The property has also been subject to various street sanitation matters, including reports of graffiti (2023), garbage (2019), and waste clean-up needs (2018), though all these issues were resolved. A brief sprinkler/standpipe system issue was reported and corrected in September 2017. The planning records indicate no active development proposals or concerns.
