1230 Green St, San Francisco, CA 94109

The three-unit, three-story multi-family residential building at 1230 Green Street in Russian Hill, owned by David J. Oster, has undergone several significant renovations since its construction in 1911. Most notably, in 2018-2019, substantial improvements were made to the ground floor, including the addition of a media room in the existing garage, a new bathroom, bathroom revisions, and bike parking, accompanied by comprehensive electrical and plumbing upgrades including three new tankless water heaters and a wall heater, at a total cost of $50,000.

Earlier improvements included a third-floor kitchen and bathroom remodel in 2004 ($25,000), garage expansion and stair repair in 2002 ($60,000), and various electrical upgrades. The building has had some regulatory history worth noting, including several past violations that have since been resolved. In 2003, there were multiple building code violations related to unpermitted work, improper pipe installation, and water heater issues, as well as fire safety concerns that were addressed by April 2008.

A 2023 complaint about potential paint drift from nearby scaffolding and a 2021 report of a missing side sewer vent cover indicate ongoing maintenance and neighborhood interaction. Recent infrastructure issues have been primarily related to sewer systems, with documented back-up incidents in 2021 and 2024. The building's permit history shows consistent maintenance and upgrading of systems, including electrical, plumbing, and general repairs, with most recent street space permits issued in 2019.
