MCCARTHY BUILDING COMPANIES, INC. MARKS TWO MAJOR CONSTRUCTION MILESTONES IN ONTARIO’S MULTI-BILLION-DOLLAR COMMUNITY EXPANSION EFFORT

Completion of the $32.6 million City of Ontario Parking Structure and groundbreaking of the $53 million Vineyard Parking Structure highlight McCarthy’s growing partnership with Ontario and its shared commitment to community-centered progress 

ONTARIO, Calif.—McCarthy Building Companies, Inc. (McCarthy), one of the nation’s largest and most diversified construction firms, has reached two major construction milestones in the City of Ontario with the completion of the City of Ontario Parking Structure, part of the city’s transformative Civic Center Campus Expansion, and the groundbreaking of the Vineyard Parking Structure, a key component of Ontario’s forthcoming Sports and Entertainment District. Together, these milestones underscore the city’s multibillion-dollar investment in civic mobility, recreation, and long-term community growth, while also reflecting McCarthy’s expanding partnership with Ontario and its commitment to high-quality, efficient delivery. 

The newly completed six-story, $32.6 million City of Ontario Parking Structure, which first broke ground in February 2024, delivers more than 300,000 square feet and 821 parking stalls to support the Civic Center, City Hall, nearby residential areas, and future community activity. Designed to integrate seamlessly with the surrounding urban environment, the structure incorporates a series of features prioritized by the city, including a photovoltaic (PV) solar array, an advanced red-light/green-light parking guidance system, and infrastructure for 48 EV charging stations, with 21 installed at opening. Durable materials including colored CMU block, decorative metal elements, and pre-cast panels were intentionally selected to ensure long-term resilience and aesthetic cohesion.  

Following the completion of the City of Ontario Parking Structure, McCarthy has also broken ground on the $53 million, six-level, 1289-stall Vineyard Parking Structure, including 60 EV Chargers with infrastructure for an additional 183, a photovoltaic (PV) solar array, an extensive parking guidance system with a sensor at every stall to supporting the city’s new 100+ acre Sports and Entertainment District, which will include new soccer and baseball fields, public amenities, and a future Minor League Baseball stadium. Developed under a design-build model, the structure will feature a prominent east elevator cores to enhance pedestrian flow and safety, decorative glazing, fabric graphics, and a planned 50’ x 150’ video wall to support events and elevate the visitor experience. The Vineyard Parking Structure is expected to be completed in September 2026. 

McCarthy self-performed all concrete, earthwork, metal panels, plaster, fire extinguisher cabinets, doors/frames/hardware and civil utilities for both structures, allowing for tighter schedule management and greater control over quality and safety to maintain a seamless flow from project to project. 

“Being able to support two major projects for the City of Ontario back-to-back has been an incredibly meaningful experience for our team,” said Andrew Raufi, Vice President Project Executive, McCarthy. “We’re proud of the trust Ontario has placed in McCarthy and honored to contribute to the city’s long-term vision.” 

These two parking structures mark the latest chapter in McCarthy’s relationship with the City of Ontario, which in recent years has also included the completion of the C-Block Parking Structure to support the city’s rapid growth and long-term community ambitions. With Ontario planning more than $3 billion in upcoming enhancement projects, from civic infrastructure to major recreational investments, the city continues to position itself as a leading regional destination for residents, businesses, and visitors. McCarthy’s collaboration with Ontario reflects a shared focus on building facilities that serve both immediate community needs and the city’s long-range development vision. 

“From start to finish, the entire process with McCarthy was handled with professionalism, clear communication, and a high level of craftsmanship.” Dan Beers, Design & Construction Director, City of Ontario. “McCarthy consistently delivered on time, stayed within budget, and have always been responsive to our questions and any concerns we’ve had along the way.” 

A defining element of both projects is the strength and continuity of McCarthy’s craft workforce and trade partners, many of whom come from communities across the Inland Empire. Nearly all carpenters and laborers from the City of Ontario Parking Structure transitioned directly to the Vineyard project, and approximately 70 percent of trade partners remained consistent between the two builds. This locally based continuity has enhanced collaboration, reduced onboarding time, and allowed lessons learned to be applied immediately to the Vineyard Parking Structure, reinforcing both efficiency and McCarthy’s investment in the local Ontario workforce.
