How Do I Budget a Trampoline Park Buildout?
Budget $35 to $55 per square foot for the buildout of a trampoline park in a leased shell, with a typical 25,000 to 40,000 sq ft box landing your all-in project cost between $1.2M and $2.5M including equipment. The single biggest line item is the court system itself: a professional-grade trampoline and foam attraction package from a manufacturer like Skyzone (via its supplier ASTM-compliant builds), Sky High, Get Air, or court fabricators TopJump, Spring Air, or Funtek runs $15 to $25 per square foot of attraction floor, which on a 20,000 sq ft activity area is $300,000 to $500,000 before you touch a single wall.
The money move that saves you the most: do not pay retail rent on the cubic footage you actually need. Trampoline parks require 22 to 28 feet of clear height (the distance from finished floor to the lowest obstruction — joists, ductwork, sprinkler heads). Old big-box retail and grocery shells often have only 16 to 20 feet clear, which forces you into expensive industrial space at $8 to $14/sq ft NNN.
Negotiate a free-rent buildout period of 4 to 8 months and a tenant improvement (TI) allowance of $15 to $40 per square foot before you sign — that allowance alone can cover your entire foam, springs, and netting package. Skipping that negotiation is the most common way operators leave $400,000+ on the table.
What Actually Drives the Budget
The court package dominates, but six line items decide whether you come in at $1.2M or $2.5M:
- Attraction package (springs, beds, foam pits, padding): $300,000 to $600,000. Springs are consumables — a 20,000 sq ft park burns through $8,000 to $15,000/year replacing fatigued springs and torn beds. Foam cubes for the pits are $1.50 to $3.00 each and you need 8,000 to 12,000 of them.
- Specialty attractions: Ninja warrior courses ($40,000 to $120,000), warped walls, battle beams, climbing walls ($25,000 to $80,000), and toddler zones add experience and price. A drop slide or skywalk runs $30,000 to $90,000.
- HVAC: This is the silent budget killer. A high-volume jumping space generates massive heat and humidity load — plan $8 to $14 per square foot for adequate tonnage. Underspending here means a sweaty, smelly park and bad reviews.
- Flooring, rubber, and impact attenuation: $3 to $7 per square foot.
- Restrooms, party rooms, and concessions: Party rooms are your profit engine — a park can run $10,000 to $30,000/party room in finish-out but those rooms drive 30 to 40% of revenue.
- Fire/life safety upgrades: Sprinkler relocation and added egress for high-occupancy assembly use can hit $50,000 to $150,000.
Clear Height, Column Spacing, and Why the Shell Decides Everything
You cannot value-engineer your way around physics. The attraction layout needs 22 to 28 feet of clear height for safe airtime over performance trampolines and at least 24 feet for any "supertramp" or wall-tramp feature. Just as important is column spacing: tightly spaced structural columns (common in older shells at 20-foot bays) chop up your court layout and waste 5 to 12% of usable attraction floor.
Aim for 40-foot-plus clear spans.
Before you sign, pay $3,000 to $7,000 for a structural and MEP (mechanical/electrical/plumbing) feasibility study. It will tell you whether the roof structure can hang the dead load of ninja course rigging and whether the existing electrical service (you want at least 800 amps, ideally 1,200) can handle HVAC plus arcade redemption games.
An operator who skips this study and discovers an undersized panel mid-construction pays $40,000 to $90,000 for a utility service upgrade — a cost the landlord will rarely cover after lease signing.
Don't Get Screwed by the Landlord
This is where money is won or lost. Landlords love trampoline parks because they fill dead big-box space, which means you have leverage — use it.
- Demand a real TI allowance. For a 30,000 sq ft space, push for $25 to $50 per square foot ($750,000 to $1.5M). Landlords amortize it into rent, so model the true cost, but free capital up front beats financing equipment at 12%.
- Get the allowance paid on a schedule you control. Insist the TI is disbursed against AIA pay applications during construction, not as a single reimbursement after you open. A "paid upon opening" clause forces you to float the entire buildout — a cash-flow trap that has bankrupted operators.
- Cap your share of CAM (common area maintenance). Demand a CAM cap of 3 to 5% annual increases and exclude capital repairs to roof and structure — you should never pay to replace the landlord's roof through CAM.
- Negotiate the demising and HVAC baseline. Make the landlord deliver the space with a functioning, code-compliant HVAC system at a stated tonnage and a warm, dry, watertight shell. Get "landlord delivers in white-box condition" defined in writing with a punch list.
- Lock a long term with options, not a long obligation. Take a 7 to 10 year initial term with two 5-year options so you control renewal, but resist a 15-year personal guarantee. Negotiate the personal guaranty down to a "burn-off" that expires after 36 months of on-time payments.
- Co-tenancy and exclusivity: If you're in a center, get an exclusive use clause barring another trampoline or "active entertainment" tenant, and a co-tenancy clause that reduces rent if the anchor goes dark.
Don't Get Screwed by the Contractor
The general contractor relationship is the second place budgets explode.
- Bid the job to at least three GCs with experience in assembly-occupancy and high-bay recreation — not a strip-mall retail GC. Recreation buildouts have unusual structural and MEP demands.
- Use a GMP (guaranteed maximum price) contract, not cost-plus with no cap. A GMP forces the GC to eat overruns inside the contingency.
- Hold 10% retainage until the punch list is 100% closed and you have your certificate of occupancy in hand.
- Separate the court installer from the GC. Your trampoline manufacturer's certified installation crew should set the courts; keep that contract direct so the GC can't mark it up 15 to 25%.
- Define the contingency. Carry a 10 to 15% construction contingency — recreation shells reveal surprises (sub-slab plumbing, inadequate roof structure) once demo starts.
Where the Smart Money Trims (Without Killing Revenue)
Cut these without hurting the guest experience: oversized arcades on day one (add redemption games in year two once you know traffic), custom millwork in party rooms (use durable laminate), and premium exterior signage if your visibility is already strong. Do not cut HVAC tonnage, spring quality, foam pit depth, or staff sightline design — those create the injuries, complaints, and bad reviews that sink a park.
A park that opens with a tight $1.3M build but proper HVAC and safety beats a $2.2M park with a cheap mechanical system every time.
Phasing also protects cash: open with the core court, foam pits, and two party rooms, then add the ninja course and climbing wall in month 9 to 12 funded by operating cash. This lowers your day-one capital need by $150,000 to $300,000.
FAQ
How much does it really cost to open a trampoline park? All-in, including buildout, equipment, soft costs, and pre-opening, plan $1.2M to $2.5M for a 25,000 to 40,000 sq ft park. Smaller "park-in-a-box" formats under 15,000 sq ft can open closer to $700,000 to $1M, but they generate proportionally less revenue.
What clear height do I absolutely need? A safe minimum is 22 feet clear; 24 to 28 feet is ideal and required for wall-tramp and supertramp features. Below 20 feet clear, walk away — you cannot safely or legally operate most attractions.
Should I take a big TI allowance or lower rent? Run the math both ways. A large TI ($25 to $50/sq ft) preserves your cash but gets amortized into higher rent over the term. If your cost of capital is high, take the TI. If you're well-capitalized, negotiate lower base rent and free months instead. Never take zero of both.
What's the most common buildout mistake? Undersizing the HVAC. Operators chase the visible attractions and shortchange the mechanical system, then spend the first summer with a hot, humid, smelly park and refunds. Spec the tonnage for peak occupancy plus jumping heat load.
