Conditional. Each fan may carry one clear plastic/vinyl/PVC bag no larger than 12" x 6" x 12", or a one-gallon clear plastic freezer bag, plus a small clutch bag/wallet no larger than 6.5" x 4.5". All bags are subject to search. Backpacks, purses/bags larger than a small clutch, luggage, computer/camera bags, briefcases, fanny packs and cinch bags are not approved. A fee-based Mobile Locker Company storage option is available near the gates for guests with non-approved bags. Max size: 12" x 6" x 12" (clear bag) or 1-gallon freezer bag; clutch max 6.5" x 4.5". Max quantity: 1 clear bag/freezer bag + 1 small clutch per fan. Fee: Mobile Locker Company storage available for a fee. Exceptions: Medically necessary items and diaper bags

Conditional. Sealed, non-flavored/non-carbonated bottled water and empty plastic water bottles are permitted; must fit in an approved clear bag. Sealed single-serving juice boxes and formula/baby food are also permitted. No metal or glass containers. Exceptions: Formula/baby food exempt from the water-only restriction

Allowed. Outside food is permitted as long as it is carried in an approved clear plastic bag. The Diamondbacks do not restrict specific food types brought in, only the container/bag it must be carried in.

Conditional. Exceptions to the standard bag/prohibited-items policy are made for medically necessary items after inspection at the ADA screening lanes (Gate A or E). Guests with medical or other special needs are encouraged to contact the Disability Services Manager in advance of the game.

Not Allowed. Outside alcohol is prohibited; alcohol is sold inside the ballpark to guests 21+ with valid ID. In-park alcohol sales are limited to 50 oz of beer, 1 liter of wine, or 4 oz of distilled spirits, max two drinks per person per ID, and sales stop at the start of the 8th inning.

Not Allowed. Drugs and other illegal substances, explicitly including medical marijuana, are prohibited.

Not Allowed. Coolers of any kind are not permitted — the beverage policy only allows sealed water bottles, empty bottles, and sealed juice boxes (explicitly banning metal, glass, and thermos-style containers), and the bag policy caps all bags well below cooler size.

Conditional. Strollers are welcomed as long as they don't block aisles or guest movement; official policy does not separately address wagons. Strollers may be checked at Guest Relations (Section 128 main concourse or Section 322 upper concourse) but are not available to rent, and are subject to search by game-day security. Exceptions: Wagons are not mentioned in official team policy

Conditional. Nursing accommodations are available at the Suite Office across from Suite 42 on the Suite Level. Formula and baby food are also explicitly permitted through the bag/beverage exceptions.

Allowed. Wheelchairs and other mobility devices are accommodated with dedicated screening lanes at Gates A, C, E, J, K and the Bridge Entrance. Guests using these lanes undergo a light pat-down or hand-wand search plus inspection of the mobility device instead of walking through the metal detector. The team also has a limited number of wheelchairs (250 lb capacity) to transport guests to/from seats, first-come first-served.

Not Allowed. Skateboards, rollerblades, scooters, razors, and shoes with wheels are prohibited.

Conditional. Hand-held, non-professional still and video cameras are allowed provided game action isn't recorded (per MLB mandate); lens can't exceed 8" long / 4" wide, and no tripods or monopods.

Not Allowed. Drones and other remote-controlled vehicles are prohibited.

Not Allowed. Umbrellas are on the official prohibited items list and are not permitted inside Chase Field, regardless of the retractable roof's open/closed status.

Conditional. Blow horns/noisemakers are banned; flags with poles are only allowed if sold in the Team Shop; banners/signs must be baseball-related and in good taste, non-commercial, and can't block views or use wood/metal supports. The team reserves the right to remove any banner, sign, or flag at its discretion.

Conditional. Blankets are allowed if carried over the shoulder (subject to inspection); one-piece foam seat cushions up to 18" wide without pockets/zippers are also permitted. Max size: Seat cushions: max 18" wide.

Not Allowed. Firearms, knives, and weapons of any kind are prohibited; only active, credentialed federal or Arizona state law enforcement officers may carry a firearm. Pocketknives must be returned to the guest's vehicle — the team does not hold or store personal items at the gate.

Conditional. Chase Field is a non-smoking facility, including e-cigarettes, cigars, and traditional cigarettes; smoking is only allowed in designated outdoor areas outside Gates A, F, J, and K. Guests need their digital ticket to re-enter after stepping outside to smoke, since these areas are outside the ballpark. Exceptions: Designated outdoor smoking areas outside Gates A, F, J, K

Conditional. Animals are prohibited except for service animals.

Conditional. Re-entry is allowed only through designated gates (A, F, J, and K); guests must show their ticket and be scanned out, then show ticket again to be scanned back in. On giveaway days, re-entry temporarily shifts to Glass Doors north of Gate A and between Gates K & J while giveaway items last.

Conditional. Also prohibited: aerosol cans, fireworks/incendiary devices, laser pens, fishing nets, beach balls/balloons/inflatables (without prior approval), frisbees, bicycles (park at designated racks outside — not permitted inside), and bubble-making liquids/machines. The team notes additional items may be prohibited at Chase Field management's discretion.
