Commercial construction costs $240 to $870 per square foot on average, depending on the location and building type. Commercial projects in the Midwest and South usually cost less than on the East or West coast.

Warehouses and parking garages cost the least to build, while high-rise office buildings, museums, or five-star hotels cost the most.

A commercial building is any structure in which at least 50% of its square footage is used for retail, food, or other operations that serve clients in some way. This includes retail stores, restaurants, warehouses, museums, hospitals, hotels, schools, or office buildings.

Commercial buildings provide a service to customers or community members. Residential buildings are used primarily for small-scale homes and include single-family homes, townhomes, or duplexes.

Apartment buildings and condominiums with 5 or more units are techinically residences but fall under the commercial category because they’re primarily designed to make money on a large scale.

A straightforward or small commercial building typically takes between 4 to 6 months to build. However, for large or complex structures, the construction may take 8 to 10 months. The exact timeline depends on the type of structure, weather, and material shipping delays.
