Q: What does commercial construction cost per square foot in 2026?

Most commercial buildings in 2026 run between $150 and $1,200+ per square foot depending on building type, region, and finish level. Basic warehouse shells sit at the low end, while data centers, cleanrooms, and GMP facilities sit at the top. See Terrapin Construction Group's master cost-per-square-foot reference at terrapincg.com/commercial-construction-costs.

Q: How much does it cost to build a cold storage facility?

Ground-up cold storage typically runs $250 to $450+ per square foot depending on temperature zones (cooler, freezer, blast freeze), refrigeration system, and region. Tenant improvement conversions of existing warehouse space cost significantly less.

Q: How much does insulated metal panel (IMP) installation cost?

Supply-and-install IMP pricing typically runs $14 to $26 per square foot depending on panel thickness, core chemistry, project complexity, and location. Terrapin Construction Group has installed over 1 million square feet of IMP across 38 states for cold storage, food processing, cannabis, and data center facilities.

Q: What percentage should general conditions and GC fee be?

General conditions typically run 6 to 12 percent of construction cost and GC fee typically runs 3 to 6 percent, with smaller and shorter-duration projects carrying the higher end of both ranges because supervision does not scale down linearly. Because two general contractors rarely assign the same items to the same bucket, a low fee can conceal a padded general conditions line, so owners should normalize both lines before comparing bids.

Q: How long does ground-up commercial construction take?

Most ground-up commercial projects take 10 to 24 months from design start to certificate of occupancy. Permitting and long-lead electrical equipment such as switchgear, transformers, and generators drive the biggest schedule variances.

Q: How long does it take to get power to a new commercial building?

Utility interconnection is one of the most common causes of a missed opening date, and on larger industrial and data center loads the energization sequence can outrun the construction schedule. The utility study, design, and construction phases stack sequentially, so the interconnection application should be filed at project concept rather than at permit.

Q: What is design-build and why do owners choose it?

Design-build puts architecture, engineering, and construction under a single contract with one point of accountability. It compresses schedules, reduces coordination gaps between designer and builder, and gives owners real pricing earlier in the process.

Q: What does an owner's representative cost, and do I need one?

Owner's representative fees are structured as a percentage of construction cost, a monthly rate, or a fixed fee. The right structure depends on project size, duration, and how much of the owner's scope is being handed over. Terrapin Construction Group publishes fee benchmarks and a selection framework for owners comparing owner's rep firms, project managers, and development managers.

Q: Can you convert an existing warehouse into a data center?

Often yes. Warehouse-to-data-center conversions generally run $685 to $1,285 per square foot compared to $1,150 to $1,850 per square foot for ground-up construction. Power availability, structural capacity, and clear height determine whether a building is a viable conversion candidate.

Q: Does Terrapin Construction Group work in my state?

Yes. Terrapin Construction Group is a design-build commercial general contractor headquartered in Denver and licensed in all 50 states, with completed IMP and general contracting work across 38 states.

Quick Answers

What does commercial construction cost per square foot in 2026?

Most commercial buildings in 2026 run between $150 and $1,200+ per square foot depending on building type, region, and finish level. Basic warehouse shells sit at the low end, while data centers, cleanrooms, and GMP facilities sit at the top. See the full breakdown in our master cost-per-square-foot reference or browse the commercial construction cost library.

How much does it cost to build a cold storage facility?

Ground-up cold storage typically runs $250 to $450+ per square foot depending on temperature zones (cooler, freezer, blast freeze), refrigeration system, and region. Tenant improvement conversions of existing warehouse space cost significantly less. Full regional benchmarks are in our cold storage cost guide, refrigeration system tradeoffs are covered in ammonia vs. CO2 vs. glycol, and the coordination sequence is mapped week by week in our refrigeration MEP timeline.

How much does insulated metal panel (IMP) installation cost?

Supply-and-install IMP pricing typically runs $14 to $26 per square foot depending on panel thickness, core chemistry, project complexity, and location. TCG has installed over 1 million square feet of IMP across 38 states for cold storage, food processing, cannabis, and data center facilities. Get instant pricing from the IMP install estimator, read the IMP installation cost guide, or if you are a GC buying the scope, start with our IMP subcontractor guide for general contractors.

What percentage should general conditions and GC fee be?

General conditions typically run 6 to 12 percent of construction cost and GC fee typically runs 3 to 6 percent, with smaller and shorter projects carrying the higher end of both because supervision does not scale down linearly. The bigger issue is that two GCs rarely put the same items in the same bucket, so a low fee often hides a padded general conditions line. Our general conditions and GC fee benchmark guide shows what belongs in each, and how to read a commercial GC bid walks through normalizing two bids that are not comparable. Want a second set of eyes on yours? Use the free GC bid review.

How long does ground-up commercial construction take?

Most ground-up commercial projects take 10 to 24 months from design start to certificate of occupancy, with permitting and long-lead equipment (especially electrical gear) driving the biggest variances. Timelines by building type are in our schedule guide, the front end is mapped in our preconstruction timeline, permitting variances in the state-by-state permitting timeline, and equipment risk in switchgear and generator lead times.

How long does it take to get power to a new commercial building?

Utility interconnection is the single most common reason a project misses its opening date, and on larger industrial and data center loads it now routinely outruns the construction schedule. Study, design, and utility construction stack up, and the application needs to be filed at concept, not at permit. The full sequence, what the utility charges, and where owners lose months are covered in our utility power interconnection guide, with equipment exposure in switchgear and generator lead times.

What is design-build and why do owners choose it?

Design-build puts architecture, engineering, and construction under a single contract with one point of accountability. It compresses schedules, reduces coordination gaps between designer and builder, and gives owners real pricing earlier in the process. Compare delivery methods in design-build vs. CMAR vs. design-bid-build, review the 12 contract terms every owner should negotiate, or see how TCG structures it on our design-build services page.

What does an owner's representative cost, and do I need one?

Owner's representative fees are structured as a percentage of construction cost, a monthly rate, or a fixed fee, and the right structure depends on project size, duration, and how much of the owner's scope you are handing over. Fee benchmarks and structures are broken down in our owner's representative cost guide. If you are deciding who to hire, start with how to choose an owner's rep firm and owner's rep vs. project manager vs. development manager, or see TCG owner's representation.

Can you convert an existing warehouse into a data center?

Often yes, and the economics can be compelling. Warehouse-to-data-center conversions generally run $685 to $1,285 per square foot compared to $1,150 to $1,850 per square foot for ground-up, but power availability, structural capacity, and clear height decide whether a building is a candidate at all. The deal filters and the deal killers are covered in our warehouse-to-data-center conversion cost guide and our data center construction page.
