For a city that has spent two decades building itself one park at a time, Maricopa's newest addition is a different kind of first. The Fieldhouse at Copper Sky, a nearly 44,000-square-foot indoor recreation building, will open its doors to the public on Saturday, Oct. 10, with a free celebration running from 9 a.m. to noon at 17985 W. Greythorn Drive.
The morning will begin with a ribbon-cutting ceremony, then give residents their first chance to walk through a building that has been in the works for more than two years. Visitors can shoot hoops, play volleyball and pickleball, take part in arts and crafts, and let kids burn off energy in an inflatable play area. Food trucks will be on hand, and Phoenix Championship Wrestling will put on a professional wrestling show.
The scale of the space is the point. The building can accommodate four full-size basketball courts, six volleyball courts or 12 pickleball courts, though not all of them can be used at once. It can be divided into four separate courts or left as one large open area of roughly 33,000 square feet. It also includes what city officials describe as "flex spaces" adaptable for classrooms, meetings or social gatherings, plus a tournament lobby for relaxing between games.
The project was first proposed in 2024 as a $16.2 million facility, part of an effort to add indoor court space as Maricopa's recreation programs kept growing. Construction began in summer 2025. City officials have said the additional space is needed because Copper Sky's existing facilities have become increasingly booked.
That pressure is a product of the city's remarkable growth. Maricopa incorporated in October 2003 with a population of about 1,040. By the 2020 census it had reached 58,848 residents, and it now sits at roughly 82,000, growing at more than 5 percent a year. The median age is 36.8, and the median household income is just over $96,000 — a young, family-heavy commuter city in Pinal County, south of Phoenix.
Parks and Recreation Director Rocky Brown has watched that arc from the inside, first as a coach and resident, then as the person guiding what comes next. He told ABC15 that the missing piece was clear. "One thing we were missing was a fieldhouse, an indoor facility where we could play sports year-round, things like basketball, volleyball, indoor pickleball," he said. "We're an up-and-coming and growing community. Lots of young families, lots of retirees. So we're just trying to be able to appeal to as many people as possible that live in our community."
Brown said the project was driven by the need for more indoor space for youth sports such as basketball and volleyball. "As the community grows, the needs grow, and then we weren't getting any more facilities to accommodate all these new" participants, he said.
Even the building's name took work. City Council approved "The Fieldhouse at Copper Sky" on a 4-3 vote, beating out suggestions including Copper Sky Fieldhouse, Copper Sky Sports Complex, Courts at Copper Sky and Copper Sky Sports Hall. Brown said the list came from staff brainstorming, parks board input and a little help from ChatGPT, whittled down from an initial pool of about 20 names. "Some of them just didn't feel right," he said.
The debate was not purely cosmetic. Councilmembers AnnaMarie Knorr and Amber Liermann questioned whether "fieldhouse" fit a building with no fields in it. "About half the people I spoke to had never heard the term fieldhouse in their life and I'm one of them," Liermann said. "I grew up in California, and I live in Arizona, so it's not a common West Coast term. It's really more of a Midwest term because in the Midwest, the weather is not conducive to year-round field play." Knorr preferred Champion Center at Copper Sky, a name suggested by a constituent, arguing it could apply to athletes and graduates alike.
The Fieldhouse sits across the parking lot from the existing Copper Sky Multigenerational Center, both within the Copper Sky Regional Park complex. Copper Sky itself opened in 2014 to considerable fanfare, instantly changing what the city offered residents; its aquatic center opened the same year. The new building is planned on city-owned land at the southeast corner of West Bowlin Road and North Greythorn Drive, and the project involved renovating an existing police substation on the site. Officials have described it as a pre-engineered metal building with panels in desert color tones, with a maximum height of 42 feet.
Assistant City Manager Matt Kozlowski told the council the facility was designed for indoor events and could draw sports tourism, further making Maricopa a destination. That ambition runs alongside the more immediate goal: giving a fast-growing city enough courts to go around.
Saturday's event is free and open to the public, with no ticket or capacity limit. For a community that has long measured its progress in parks, the morning marks something new — the first time Maricopa's residents will have a year-round indoor home for the sports they have been playing outdoors, and often waiting in line for.
