Factors Affecting the Total Cost to Build an Apartment Complex

The total cost of building an apartment complex is influenced by numerous factors.

Here are the most important aspects to consider.

1. Location, Location, Location

The location of your project is a major factor in the overall cost. Urban areas generally have higher land costs, higher building permit fees, and sometimes even higher material costs than rural areas.

For example, in high-demand markets like New York City or Los Angeles, the cost per square foot can be significantly higher than in mid-sized cities or rural areas.

Permits

In addition to land acquisition costs, location also affects building permits and other necessary permits. Popular, high-demand locations may come with higher fees and a more extensive permitting process.

However, these urban locations tend to generate higher rental income due to high demand.

2. Type of Apartment Complex: Affordable Housing vs. Luxury Apartments

Whether you’re building affordable housing or luxury apartments will also heavily influence costs. While the construction cost per square foot may not differ drastically, the quality of materials and amenities you choose for each type will.

For instance, affordable housing is often simpler, with builder-grade finishes and fewer amenities, which can help keep costs lower.

In contrast, luxury apartments may include high-end fixtures, upgraded flooring, and specialized amenities like fitness centers or rooftop pools, driving up the overall cost.

Luxury high-rise buildings are generally the most expensive projects, especially in urban markets where high-rise apartments are common.

3. Size of the Building and Number of Units

The number of units in an apartment complex plays a significant role in determining multifamily construction costs.

For instance, a 4-unit building may range from $500,000 to $1.8 million, while a 100-unit building can range from $10 million to $35 million or more.

Generally, the larger the complex, the higher the total project cost; however, scaling up can sometimes reduce the cost per unit due to efficiencies in materials and labor.

4. Building Design and Number of Stories

The complexity of the design and the number of stories in a building also influence the cost.

High-rise apartment buildings, with their need for advanced structural support, reinforced steel framing, and other special requirements, cost more than low-rise or mid-rise structures.

The number of floors can also impact utility requirements, safety measures, and other building code specifications.

Breakdown of Construction Costs

Here’s a closer look at the primary construction costs.

1. Hard Costs

Hard costs are expenses directly related to the actual construction of the apartment complex, including:

• materials
• labor costs
• equipment

The cost of materials such as concrete, steel, and lumber fluctuates based on the market, with prices rising over the past few years.

Other hard costs include the foundation, roofing, and interior finishes like cabinetry, flooring, and lighting.

The national average cost per square foot for apartment construction in the United States is approximately $310 for mid-rise buildings, though it can vary from $150 to $450+ depending on location and the type of complex.

2. Soft Costs

Soft costs refer to non-construction expenses necessary for project completion. They typically include architectural fees, engineering costs, building permits, legal fees, and other administrative expenses. These costs often range from 15% to 30% of the total project cost.

• Architect and Design Fees: Hiring an architect to create the floor plan and design of the building generally costs 8-10% of the project budget.
• Legal Fees and Permits: Working with a real estate attorney ensures compliance with local regulations and zoning requirements. Building permits and other legal fees are essential but vary by local jurisdiction.

3. Financing Costs

Unless you’re funding the project entirely out of pocket, there will be financing costs associated with securing a loan or mortgage.

Interest rates, loan processing fees, and finance charges all contribute to these expenses, which can add 5-15% to the overall cost.

4. Long-term Costs and Maintenance

Even after construction, you’ll need to account for maintenance costs. Utility costs for common areas, repairs, landscaping, and updates to building systems (like HVAC) are ongoing expenses.

Calculating long-term costs can help forecast the total operational expenses of the complex.

The Construction Process: From Planning to Completion

Building an apartment complex involves multiple phases, each requiring close attention to detail and project management. Here’s a breakdown of the stages in the construction process.

1. Planning and Pre-Construction

The planning phase is one of the most critical stages of apartment development, as it sets the foundation for the entire project. This stage includes:

• conducting feasibility studies
• selecting a project manager and general contractor
• obtaining necessary permits

An accurate initial budget and detailed cost analysis are essential to avoid budget overruns later.

2. Design and Permitting

Once planning is complete, you’ll work closely with architects and structural engineers to develop the final design, layout, and floor plan.

During this phase, you’ll also need to secure building permits and ensure compliance with all building codes and zoning laws. The complexity of the design can impact costs, as high-end finishes or unique architectural elements can raise the total cost.

3. Construction Phase

The actual construction phase involves the following steps:

Construction Phase	Description
Site Preparation and Foundation	Involves clearing the land and preparing it for building. Foundation work is critical and varies depending on the type of building (e.g., high-rise vs. low-rise).
Framing and Structural Work	Installation of steel framing or other structural supports is particularly necessary for high-rise buildings.
Interior and Exterior Finishing	Includes installing walls, roofing, windows, and flooring, as well as final touches like cabinetry, appliances, and paint.

4. Post-Construction and Lease-Up

After construction is complete, the lease-up period begins. The project owners may choose to sell units or lease them to tenants, generating rental income.

It’s also a good time to handle any final inspections or adjustments needed to bring the project up to code and good condition.

Working With Professionals

Building an apartment complex is a team effort that requires coordination across multiple roles. Some of the key professionals involved include:

• General Contractor: Responsible for overseeing the construction, managing labor costs, and coordinating with subcontractors for plumbing, electrical, and other services.
• Project Manager: Ensures that each phase is completed on schedule and within budget, addressing any challenges that arise.
• Architect and Engineers: Handle the design and structural integrity, often consulting on materials and cost efficiency.
• Real Estate Attorney: Assists in navigating local regulations, drafting contracts, and managing any legal fees associated with the project.

Final Considerations and Potential Risks

Several potential risks can arise in an apartment construction project, including material shortages, price fluctuations, and unforeseen site conditions.

Having contingency funds for unexpected expenses, such as legal fees or repairs due to natural disasters, can prevent delays and budget issues.

It’s also crucial to be aware of the cost of building materials, which can fluctuate due to factors like supply chain disruptions and labor shortages.

To mitigate these risks, establish a clear budget, understand the cost of land and labor costs in your area, and work with experienced professionals who can navigate these challenges.
