773-777 Oak St, San Francisco, CA 94117

The property at 773-777 Oak Street in Hayes Valley is a multi-family residential building owned by Matthew L. Diamond and Jessica, consisting of 3 units plus an ADU, first constructed in 1900. The building has undergone significant recent modifications, with major construction activity initiated in 2019 including plans for a 3-story addition with roof deck, new garage, and driveway improvements. This work, along with the conversion of a first-floor unit to an ADU, was filed under permit number 201908280090.

The property has seen substantial improvements since 2013, including a $350,000 rehabilitation project for the rear building, complete electrical rewiring, and updates to plumbing systems with a new boiler installation in 2018. A noteworthy incident occurred in late 2016 when the building received multiple violations for lead paint hazards and structural concerns, though these issues were officially abated by March 2017. The building's maintenance history includes various improvements such as kitchen and bathroom updates, electrical system refurbishments, and the addition of modern amenities like a fireplace and radiant heating system. Recent activity around the property (2023-2024) primarily involves routine urban maintenance issues such as street cleaning, sidewalk parking violations, and graffiti removal.

There have been several general cleaning cases reported through 311 calls, though these are typical for urban environments. The property has received various planning approvals and permits for its renovation and expansion projects, including a CEQA clearance and various plumbing and electrical permits between 2017-2018. Current planning records indicate proposed improvements for adding additional units, although some related permits are still showing as "On Hold" status. The building's transformation from a single-story structure to its current configuration reflects ongoing development efforts to modernize and increase housing capacity on the site, though it's important to note that certain proposed modifications are still in the approval process.
