How much does a commercial buildout cost per square foot?

Commercial buildout costs per square foot vary widely by space type. Warehouse and flex spaces are the lightest at roughly $11–$53/sqft. Retail stores run $40–$142/sqft. Coffee shops and restaurants run $93–$260/sqft. Medical offices are among the heaviest at $89–$311/sqft. Use the calculator above to get a range specific to your space type and size.

What is the difference between a low, expected, and high buildout estimate?

The low estimate assumes a straightforward buildout with minimal surprises — basic-condition space, standard finishes, and efficient design. The expected estimate reflects a typical buildout for the space type with normal scope. The high estimate accounts for premium finishes, complex MEP work, difficult existing conditions, or above-average market pricing. Actual costs depend on your region, the condition of the space, and your final design.

Does this calculator replace a contractor quote?

No. This is a preliminary planning tool — it gives you a cost range to use when evaluating whether a space and concept are financially viable before you engage an architect or contractor. For construction, you will need permit drawings from a licensed architect and bids from general contractors. BuildoutIQ is the step between your business idea and those professional engagements.

How accurate is this commercial buildout cost calculator?

This calculator produces a preliminary planning range based on industry benchmarks for each commercial space type. It is accurate enough to evaluate feasibility and have informed conversations with lenders, landlords, and contractors — but it is not a substitute for a detailed contractor bid. Actual costs vary by region, space condition, design choices, and current material and labor pricing in your market.

How this estimate is calculated

Space-type benchmarks

Each space type carries its own $/sqft range based on typical industry buildout costs — restaurants are heavier than retail; medical offices heavier than gyms.

Cost-driver adjustments

Selecting cost-driving features (like a commercial kitchen or locker rooms) applies a calibrated percentage multiplier to all three range values.

No AI, fully deterministic

Every estimate comes from the same fixed calculation. Same inputs = same output, every time. No model hallucinations, no random variation.

What does a commercial buildout estimate cover?

A commercial buildout (or tenant improvement) cost estimate covers the work of converting an empty shell space into a functioning business. That includes construction labor and materials, interior finishes (flooring, wall finishes, ceilings), mechanical / electrical / plumbing rough-in, equipment and fixtures appropriate to the space type, and permitting and contractor overhead.

It typically does not include business equipment purchased and installed separately from the buildout contract, initial inventory, furniture items bought through retail channels, lease deposits, working capital, or soft costs like architecture and engineering fees. These can add 20–40% on top of the buildout estimate depending on the project.

The ranges above are preliminary planning benchmarks — useful for sizing the investment before you engage an architect or get contractor bids. For a full line-item breakdown tied to your specific layout and equipment list, .
