I remember the first time I thought about building an apartment complex. It was overwhelming just thinking about the financial peace. You probably feel the same way—wondering if you can afford it or if it’s too big to even dream about. But here’s the thing: It’s possible. Whether you’re building affordable housing or luxury apartments, the numbers can work in your favor if you break them down.
What is the Average Cost to Build an Apartment Complex?
To give you a general idea, the average construction cost for a multifamily property in the United States in 2023 was around $350 per square foot. However, this can range from $220 to $700 per square foot depending on the following factors.
- Location
- Quality of Materials
- Design and Architecture
- Labor Costs
- Size of the Complex
- Permits and Regulations
- Site Preparation
- Utilities and Infrastructure
- Construction Methods
- Market Conditions
Location and Its Impact on Building Costs
Location is everything. Building in a high demand urban area will cost more than in a suburban or rural area. You’ll find that land prices in cities can be astronomical but the potential for higher rent increases. I remember visiting two different sites—one in the city and one a little farther out. The difference in price was huge but so was the difference in rental potential. So, where do you want to build?
How the Number of Units Affects Construction Costs
Cost varies by number of units. More units = lower cost per unit but total cost can still be all over the place. Here’s how costs change by number of units.
| Number of Units | Estimated Cost per Unit | Total Estimated Cost | Factors Affecting Cost |
| 1-10 | $250,000 – $350,000 | $250,000 – $3,500,000 | Land costs, permits, design, and basic construction |
| 11-20 | $200,000 – $300,000 | $2,200,000 – $6,000,000 | Economies of scale, shared amenities, improved efficiency |
| 21-50 | $180,000 – $250,000 | $3,600,000 – $12,500,000 | Greater economies of scale, specialized labor, financing options |
| 51-100 | $160,000 – $220,000 | $8,000,000 – $22,000,000 | Significant economies of scale, complex management, advanced construction techniques |
| 100+ | $140,000 – $200,000 | $14,000,000+ | High economies of scale, complex financing, specialized management and design |

Affordable Housing vs. Luxury Apartments: Cost Breakdown
When I started planning my apartment complex, one big decision I faced was whether to go for affordable housing or luxury apartments. Both have their pros and cons, and both impact the budget significantly.
| Cost Category | Affordable Housing | Luxury Apartments |
| Land Acquisition | Cheaper land, often in suburban or less central areas. | Expensive land in prime, central locations. |
| Construction Costs | $90 – $200 per square foot; uses basic materials. | $200 – $500+ per square foot; uses high-quality materials and elaborate designs. |
| Labor Costs | Standard labor rates. | Higher labor costs for specialized work and finishes. |
| Permits and Fees | Standard fees. | Additional fees for luxury features and faster approvals. |
| Interior Finishes | Basic fixtures and appliances. | High-end fixtures, appliances, and designer finishes. |
| Amenities | Basic amenities like simple gyms. | Extensive amenities like pools, spas, and concierge services. |
| Energy Efficiency | Basic insulation and energy-efficient appliances. | Advanced energy-saving systems and materials. |
| Technology | Basic security and communication systems. | Advanced smart home technology and security systems. |
| Landscaping and Exterior Amenities | Minimal landscaping. | Elaborate landscaping and outdoor amenities. |
| Legal and Financial Costs | Standard fees. | Higher fees due to complexity. |
| Marketing and Leasing | Lower marketing budget. | Higher marketing budget for targeting affluent renters. |
| Property Management | Standard management fees. | Higher fees due to more services provided. |
Collaborating with Architects and Contractors
Hiring the right team is essential. I worked with both an architect and a contractor who understood my vision and kept the project within budget. Architects will bring your design to life, and contractors will ensure it’s built according to plan.
Here’s what I learned:
- Architects:
Architects are the dreamers who turn ideas into physical buildings. Their fees are based on the complexity of the design and the time spent on the project. A simple design will cost less than a complex one. And the more time an architect spends on a project the more they will cost. Their expertise in design, building codes and aesthetics is key to any construction project.
- Contractors
Contractors are the people who build the architect’s design. They have their own teams of skilled workers so labor management is easier. But the cost of construction is heavily dependent on the size and complexity of the project. Bigger more complex projects require more resources and time and therefore cost more. The contractor’s ability to manage their team and get materials at the best price is key to keeping costs down.
Together, their combined efforts made my project possible. For you, it’s all about finding the right fit for your needs.
Furnishings and Finishes: Adding to the Final Cost
If you’re anything like me, the idea of designing each unit down to the finest detail can be exciting. But this also adds to the cost. High-end finishes like marble countertops or hardwood floors can quickly increase your expenses. On the other hand, opting for more budget-friendly furnishings keeps costs low.
- Functionality
- Aesthetics
- Budget
- Space
- Target Audience
- Maintenance
- Sustainability
- Accessibility
- Safety
- Comfort
- Storage
- Technology
- Personal Style
- Trends
Zoning, Building Permits, and Regulatory Costs
Zoning laws and building permits are unavoidable. These regulations are in place to ensure your complex is safe and suitable for the area you’re building in, but they can also be a headache. When I went through the process, I discovered that zoning and permit costs can range from $5,000 to $100,000, depending on where you build.
- Zoning fees
- Permit costs
- Regulatory requirements
- Inspection fees
- Impact fees
- Development fees
- Legal fees
Cost Per Square Foot for Apartment Complex Construction
The cost per square foot of constructing an apartment complex is influenced by several factors, including the overall size of the building, desired amenities, and local market conditions. Generally, larger complexes tend to have lower costs per square foot due to economies of scale. However, this can vary significantly based on specific project requirements and location.
| Size Range (sq ft) | Estimated Cost per Sq Ft | Factors Affecting Cost |
| Under 500 | $250 – $400 | Smaller scale, fewer amenities |
| 500 – 1,000 | $220 – $350 | Economies of scale, potential for shared amenities |
| 1,000 – 2,500 | $200 – $300 | Increased economies of scale, potential for more complex designs |
| Over 2,500 | $180 – $275 | Significant economies of scale, complex design considerations |
Sustainable Building Options: Going Green with Your Apartment Complex
Sustainability is a big deal these days. I wasn’t sure at first if it was worth the extra cost, but after some research, I discovered that green building options can actually save money in the long run.
- Renewable energy sources (wind turbines, geothermal)
- Green roofs and landscaping
- Low-VOC paints and materials
- Recycled and reclaimed materials
- Smart building technology
- Electric vehicle charging stations
- Waste management and recycling programs
- Green certifications (LEED, BREEAM)
- Indoor air quality improvements
- Sustainable site selection
Timeline for Getting an Apartment Complex Occupancy Ready
During that time, I learned that patience is key. Every step from site preparation to final touches can be delayed by weather, labor shortages, or unexpected issues.
This is a general estimate and can vary significantly based on project size, complexity, location, and unforeseen challenges.

Financing such a big project can be intimidating, but there are plenty of options:
| Financing Option | Description |
| Traditional Bank Loans | Offered by commercial banks and credit unions. |
| FHA Loans | Backed by the Federal Housing Administration, offering lower down payments. |
| Commercial Mortgage-Backed Securities (CMBS) | Large commercial loans often securitized. |
