Commercial Building Cost Per Square Foot by Type
Building costs vary dramatically by occupancy type. The table below shows national baseline costs — apply state multipliers for regional accuracy. These figures include structure, MEP systems, and a standard tenant improvement allowance.
| Building Type | Shell Only | Basic TI | Full Fit-Out |
|---|---|---|---|
| Office (Low-Rise) | $130–$180/sq ft | $200–$280/sq ft | $300–$420/sq ft |
| Retail / Strip Mall | $110–$170/sq ft | $190–$270/sq ft | $280–$380/sq ft |
| Warehouse / Industrial | $60–$100/sq ft | $90–$140/sq ft | $120–$180/sq ft |
| Multi-Family (Apartments) | $130–$190/sq ft | $180–$260/sq ft | $260–$380/sq ft |
| Restaurant / Food Service | $160–$220/sq ft | $260–$360/sq ft | $380–$600/sq ft |
| Medical / Healthcare | $200–$280/sq ft | $320–$420/sq ft | $450–$700/sq ft |
Frame Type Cost Comparison
The structural frame is the backbone of any commercial building. Pre-engineered metal buildings offer the best cost-to-span ratio for industrial use, while reinforced concrete is preferred for high-rise and high-occupancy structures.
| Frame System | Typical Cost Premium | Best For | Typical Span |
|---|---|---|---|
| Pre-Engineered Metal | Base (0%) | Warehouses, storage, shops | 40–200 ft clear span |
| Wood / Heavy Timber | +10–15% | Low-rise retail, residential | 20–60 ft |
| Structural Steel | +20–35% | Mid-rise office, retail | 30–120 ft |
| Reinforced Concrete | +30–50% | High-rise, parking, medical | 20–60 ft per bay |

How to Estimate Commercial Building Costs
Commercial construction budgeting follows a systematic approach:
- Define the Program: Establish gross area, occupancy type, number of floors, and any specialized spaces (data centers, clean rooms, commercial kitchens).
- Select Frame and Foundation: Site conditions and soil bearing capacity often dictate foundation type. Poor soils require deep pilings that can add $20–$60 per square foot.
- Budget MEP Systems: Mechanical, electrical, and plumbing typically represent 25–35% of total cost for commercial buildings, significantly more than residential construction.
- Plan Tenant Improvements: Core-and-shell budgets don't include tenant fit-out. Add $40–$120 per square foot for standard office improvements, more for medical or food service.
- Apply Soft Costs: Add 15–25% for architecture, engineering, permits, inspections, project management, and contingency.
Frequently Asked Questions
How much does it cost to build a commercial building per square foot?
Commercial building costs range from $130 to $380+ per square foot depending on frame type, occupancy classification, and location. Warehouses typically cost $80–$150/sq ft while office buildings run $200–$400/sq ft.
What is the cheapest type of commercial building to construct?
Pre-engineered steel or metal buildings are typically the most cost-effective, with costs starting around $30–$60 per square foot for the structure. Including site prep, foundation, and interior fit-out, expect $80–$150 per square foot total.
How does occupancy type affect building costs?
Occupancy type directly impacts code requirements, fire suppression, HVAC, and egress specifications. Retail and restaurant spaces with heavy plumbing and electrical fit-outs cost more per square foot than basic office or warehouse space.
What percentage of a commercial building budget goes to labor?
Labor typically accounts for 40–50% of total commercial construction costs, with materials representing 40–50% and permits, insurance, and overhead making up the remaining 10–15%.

Related FAQs
How does building structure affect total cost?
Steel and concrete framing typically run 10% to 20% higher in material and specialized labor costs than wood framing, but offer superior structural load capacities.
What are soft costs in commercial construction?
Soft costs include architectural design fees, engineering fees, building permits, taxes, and legal services, which usually total 15% to 30% of the overall budget.
