At one of Koreatown’s busiest corners, the old county office tower is getting a full-on glow-up. At 6th Street and Vermont Avenue, the 12-story former Los Angeles County Department of Mental Health building at 550 S. Vermont is swapping its mid-century concrete exterior for a full glass curtain wall as crews push ahead on a $210 million renovation. The project is set to expand the tower by roughly 88,000 square feet, bringing its total to about 243,000 square feet and adding a small ground-floor retail bay. With the new glazing already visible from the street, the long-running Vermont Corridor redevelopment is clearly entering its final phase.
Board Sign Off And The Big Money
Per the Los Angeles County Board of Supervisors, the board certified an addendum to the Vermont Corridor Final Environmental Impact Report and authorized the Site 2 renovation (Capital Project No. 87802), approving a guaranteed maximum price of $210,000,000 and bond financing not to exceed $260,000,000. The county paperwork lays out the square-footage math: roughly 154,793 gross square feet of existing space will be renovated and approximately 88,340 gross square feet of new Class A office space will be added, for a total near 243,133 gross square feet. The plan also calls for about 12,050 square feet of renovated subterranean support space. The transaction will run through a lease-leaseback with Los Angeles County Facilities 2 Inc., and the board reserved the option to treat the job as a “Covered Project” under the county’s Community Workforce Agreement, which would govern hiring and labor standards.
Design Team And Glassy Facelift
Design firm Gensler is steering the makeover, while Trammell Crow Company is leading development and Snyder Langston is listed as general contractor, as reported by Urbanize LA. The new glass curtain wall is designed to echo the county’s 21-story DMH headquarters just to the north, giving the block a more unified, modern look. The retrofit also includes structural work to extend floor plates and about 2,000 square feet of street-level commercial space, as crews continue recladding the exterior and building out the interiors.
Vermont Corridor Nears The Finish Line
This renovation caps the multi-site Vermont Corridor plan, which earlier phases used to deliver a new county headquarters tower and an affordable housing component across the street, a strategy that was closely tracked when the project was first proposed. Experts and developers have repeatedly framed the effort as a transit-oriented cluster of offices, retail, and housing within walking distance of Metro Red and Purple Line stations, a key selling point for the original master plan. That history helps explain why county leaders opted for a renovate-and-expand approach for Site 2 instead of a full conversion to market housing, aligning public services more tightly with transit and neighborhood amenities, per reporting from Multifamily Executive.
Timeline And What Neighbors Can Expect
Board materials and project coverage put construction at roughly a 31-month run for the renovation and expansion, and recent site photos show the new glass largely in place along Vermont Avenue. The board authorized the financing plan and the leaseback mechanism that will allow the county to accept title once bond obligations are satisfied, while developers and county staff still need to hammer out tenant moves and street-level leasing in the coming months. Neighbors should be ready for scaffolding, intermittent lane restrictions, and continued exterior activity as crews finish the glazing and move inside for tenant fit-outs.
The glass makeover at 550 S. Vermont is set to change the block’s look and, by folding county offices back into a refurbished site, aims to centralize public services within Koreatown. Watch for formal move-in schedules and retail announcements as the project shifts from exterior work to interior build-outs later this year.
