678 3rd Ave, San Francisco, CA 94118

The two-unit residential building at 678 3rd Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1905, currently owned by Mary Devries. The property has undergone several significant improvements over the past decades, with the most recent being a bathroom renovation and furnace replacement completed in 2021 at a cost of $13,000, following earlier furnace and water heater upgrades in 2020 and 2016 respectively.

Two notable structural improvements include a complete reroofing in 2000 ($16,265) and the installation of foundation bolts in 1990, which are critical for seismic safety. The building's maintenance history includes emergency electrical repairs in 2016 due to damage from a tree branch, and there were multiple 311 calls between 2013 and 2014 related to sidewalk defects and tree root issues, with multiple reports of lifted sidewalk problems. These infrastructure issues appeared to be resolved through appropriate channels, including involvement from the Department of Public Works.

More recent incidents have primarily been parking-related, with two enforcement requests in 2024 and 2021. While there was one incident involving medical waste (needles) reported in 2009, this was an isolated occurrence. The building's permit and maintenance history suggests regular upkeep and response to infrastructure needs, with no major safety concerns currently on record.
