What it costs to build a self storage facility in Iowa in 2026
A 75,000 net sq ft climate-controlled storage facility runs $13 million to $26 million, about $229 per net sq ft all-in. On Iowa's own rents, vacancy and lending terms the typical case does not pencil. Every figure below has its source; checked October 28, 2026.
Cost to build, typical case
| Land | $2,573,529 |
| Hard cost | $9,905,660 |
| Soft cost | $2,476,415 |
| Contingency | $742,925 |
| Interest reserve | $772,059 |
| Developer fee | $686,275 |
| Total, a 75,000 net sq ft climate-controlled storage facility | $17,156,863 |
| Range, low to high case | $12,574,850 to $25,581,395 |
Terrapin 2026: multi-story climate-controlled hard cost $105 to $170 per gross sq ft plus 25 to 40% site and soft, at 80% efficiency. Rule of thumb: Required rent per sq ft per month is roughly all-in cost per net sq ft divided by 80. At $175 per sq ft that is $2.19, which is why Dallas, Houston and Austin are oversupplied.

How self storage facility projects get financed
Who lends. Banks and credit unions for construction; CMBS and life companies at stabilization; SBA 504 for owner-operated facilities.
Typical stack. 25 to 35% equity conventional; SBA 504 to 90% of project cost when the owner operates it.
SBA. Eligible since 2010. Now classified special-purpose under SOP 50 10 8, so new construction requires an independent feasibility study; SOP 50 10 8.1 underwriting took effect October 1, 2026.
What a lender will ask for
- Independent feasibility study (SBA requirement for new builds)
- Three-mile supply study: square feet per capita and planned facilities
- Lease-up pro forma with an interest and operating reserve
- Operator or third-party manager
- Site traffic and visibility
SBA and most banks require an independent self-storage feasibility study ($7k to $22k). This screen is the supply check you run before commissioning it.
