The following factors also affect the cost of building an apartment complex:

  • Apartment sizes – Your final cost will depend on the square footage per unit and the number of stories in your complex. A basic mid-rise complex has 5 to 10 stories and about 50 units. In comparison, a two-unit duplex costs $100 to $230 per square foot or $200,000 to $460,000 total.

  • Apartment design – Basic fixtures cost less than luxury materials and amenities. Luxury high-rise apartments cost more to build but tend to make more money in rent.

  • Region – Apartments built on the east or west coast tend to cost more than in the Midwest or south. Land close to restaurants, schools, highways, major cities, and bodies of water is also worth more.

  • Land – Before you can plan to build an apartment complex, you’ll have to own the land itself. Lot prices range from $1,500 to $200,000 per acre, depending on the location and size.

  • Hard vs. soft costs – Hard costs include materials, labor, utilities, and other costs that directly relate to building. Soft costs include designs, inspections, taxes, fees, permits, and other costs indirectly related to construction. Soft costs are typically 20% to 30% of the budget.

  • Financing – Borrowing costs include processing fees and interest paid to the bank or lender.

  • Maintenance – After construction, you may need to pay for utilities, landscaping costs, and relevant maintenance fees for elevators, gyms, pools, or laundry equipment.

  • Building permits – General contractors typically obtain building permits and include the fee in their labor charges. Make sure to research zoning permits for multifamily units before buying land to make sure you can build an apartment complex in your desired location.

Labor

Before you can start building an apartment, you’ll need to hire several different professionals to help you design your building, make sure the land and plans are sound, and begin construction:

  • An architect charges $100 to $250 per hour

  • A structural engineer charges $100 to $220 per hour

  • A general contractor costs $50 to $150 per hour.

  • An interior designer costs $50 to $200 per hour.

  • Electrician services cost $50 to $130 per hour.

  • Plumber services cost $45 to $150 per hour.

If you haven’t purchased land yet, consider hiring a lawyer. A real estate attorney can help you navigate construction laws and zoning regulations as well as draft contracts for your contractors.
