A breakdown of multi-family construction costs in Florida can sharpen your pre-construction appraisal and risk assessment. As you evaluate a proposed project, understanding how costs allocate—from hard construction to soft fees, land acquisition to equity returns—will help you gauge future market value and underwriting viability. At Mountain Cove Homes, we compile these insights to support your financing decisions.
Before diving into numbers, you may want to explore understanding the challenges of multi-family construction financing to frame your assessment.
Break down cost categories
Multifamily development costs in Florida typically allocate across four main buckets. On average, each accounts for the following share of total project outlay (Multifamily Loans):
| Cost category | Percentage of total cost |
|---|---|
| Hard costs | 37% |
| Soft costs | 24% |
| Land acquisition & demolition | 19% |
| Equity returns | 25% |
Hard costs
These are the tangible construction expenses—labor, materials, equipment and on-site services. Key line items include:
- Foundations and concrete work
- Framing, roofing, siding and finishes
- Mechanical systems (HVAC, plumbing, electrical)
- Life-safety systems (sprinklers, alarms)
- Landscaping and site improvements
Soft costs
Soft costs cover non-physical but essential services:
- Architectural, engineering and design fees
- Permits, impact studies and zoning applications
- Legal, insurance and financing fees (loan origination, interest)
- Marketing, lease-up and project management expenses
Land acquisition
This bucket spans purchase price, site preparation, demolition and remediation. It often represents nearly one-fifth of total development outlay.
Equity returns
These are projected returns paid to investors, typically around 25% of project cost. While not a hard expense, they factor into overall capitalization and influence loan-to-cost ratios.
Estimate base construction costs
Once you’ve parsed categories, you can benchmark cost efficiency at both macro and micro levels.
Per square foot
In Florida’s secondary markets such as Orlando, multifamily construction runs about $300 to $350 per square foot, slightly below the national average of $350 per square foot but above tertiary markets at $250 to $300 per square foot (Multifamily Loans).
Per unit
Current estimates place apartment construction between $84,500 and $109,000 per unit in Florida, reflecting variations in finishes, amenities and scale (Estimator Florida).
Account for unusable space
Approximately 15% of a building’s gross area is non-rentable—lobbies, corridors, amenity spaces, shafts and stairwells. Adjust your square footage calculations accordingly.
Regional comparisons
- Three-story, wood-framed buildings cost roughly $3.5 to $4.2 million to build in Florida (Estimator Florida).
- A 10-story mid-rise structure may range from $12.9 million to $18.3 million due to steel support and complexity (Estimator Florida).
Include additional fees
Beyond core construction and land, your appraisal should incorporate these common surcharges.
Developer fees
Developers typically charge around 5% of combined hard and soft costs, plus a 1–2% acquisition fee if they handle land purchase.
Impact fees
Local governments impose fees that can add thousands per unit. Examples as of 2019 (Florida Apartment Association):
| County | Road fees | Parks fees | School/Education fees | Fire fees | Police fees | Utilities |
|---|---|---|---|---|---|---|
| Hillsborough | $1,803–$2,882 per unit | $145–$274 per two-bedroom unit | $1,207–$2,357 per unit | $249 per unit | n/a | n/a |
| Collier | $3,532–$5,542 per unit | $455 (community), $1,230 (regional) | n/a | n/a | n/a | $2,562–$2,701 per unit |
| Miami-Dade | $6,485.95–$6,860.39 per unit | $1,595–$2,403 depending on district | $612 per unit (exemptions apply) | $440.40 per unit | $574.69 per unit | n/a |
Plan for contingencies
Reserve an allowance of 10–15% to cover unforeseen expenses. During cost estimating you may use:
- Initial estimate: 30–50% accuracy
- Preliminary budget: 15–30% accuracy + 20% contingency
- Refined estimate: 5–15% accuracy
- Final budget: within 5% accuracy + 5–10% contingency (Multifamily Loans)
Integrate data for appraisal
With your cost breakdown in hand, you can:
- Compare projected cost per square foot and per unit against recent comps
- Adjust loan-to-cost ratios to reflect equity return targets and fees
- Stress-test budgets for material price inflation or permitting delays
- Coordinate with underwriting by linking cost categories to risk factors
Key takeaways
- Multifamily costs in Florida split into hard costs (37%), soft costs (24%), land (19%) and equity returns (25%).
- Expect $300–$350 per square foot and $84,500–$109,000 per unit in secondary markets.
- Factor in roughly 15% unusable space when calculating gross area.
- Include developer fees (5%–7%) and local impact fees that vary by county.
- Build a 10–15% contingency into your budget and refine estimates through each accuracy stage.
