Building an indoor basketball court
Indoor courts go in basements, garages, pole barns, home gyms, schools and churches. The building is the big cost; the court itself is the floor, hoops, lines and lighting. A maple hardwood floor typically costs $12 to $26 per sq ft, which is $56,400 to $122,200 for a 94 by 50 foot court, while sport tiles or a converted garage cost far less.

When an indoor court makes sense
- You have a pole barn, large garage or basement with enough height and clear floor.
- Winters, rain or heat would stop you playing outside for months of the year.
- You are building a new home or addition and can plan the space from the start.
- A school, church or club needs a gym floor replaced or a new court in a hall.
- You want a court that doubles as a home gym or multi-sport room.

Hoops
Wall-mounted, ceiling-hung or portable, with the structure checked for the load.

Questions people ask
How much does an indoor basketball court cost?
It depends most on whether you already have the building. HomeAdvisor puts converting an unused garage or pole barn at $1,900 to $14,400. A maple floor alone runs $12 to $26 per sq ft, according to Kiefer USA.
How high should the ceiling be for an indoor court?
There is no single US code figure for homes. The rim sits 10 feet up, and shots rise well above it, so the higher the better. Ask the builder to check your clear height before you plan the floor.
What flooring do indoor basketball courts use?
Schools and arenas use maple hardwood on a sprung subfloor. Homes and multi-use rooms often use modular sport tiles or synthetic floors, which cost less and are easier to fit over an existing slab.
Can I put a basketball court in my garage?
Yes, if there is room to shoot. A typical two-car garage is too low for a full arc, but works for a hoop and shooting drills with tiles over the slab.
How long does a maple gym floor last?
Many decades with care. Maple floors are sanded and refinished periodically, and the lines repainted at the same time.
