Illinois self-storage projects sit in the rare under-stored major market: roughly 1,558 facilities and 55.6 million square feet work out to 4.35 square feet per resident against a 5.4 national average, while Midwest stabilized occupancy of 77.9 percent in late 2025 posted the strongest regional gain in the country. Studies analyze supply within a three to five mile radius, build absorption and lease-up curves, and benchmark rent against documented comparables.
FEASIBILITY TRIGGER
Self-storage is special-purpose under SOP 50 10 8; studies analyze supply within a three to five mile radius, absorption, and rent benchmarks, and elevated equity applies.
Between FY2010 and FY2026, SBA lenders approved and disbursed 82 7(a) and 504 loans for self-storage projects in Illinois, totaling $112.1 million in approved financing at an average of $1.4 million per loan. Illinois ranks #12 of 38 states tracked for self-storage SBA lending volume and accounts for 3.2% of national self-storage SBA dollar volume. 72.0% of these loans were made under the 7(a) program, the remainder under 504. 12 loans have been approved since FY2024.

Among the 59 seasoned loans in this segment (approvals FY2010–FY2021), 1.7% reached adverse resolution — purchased, liquidated, or charged off. The national benchmark for self-storage is 1.1%, against 7.3% across all industries. That performance runs above the national benchmark for this asset class, which is a factor lenders weigh in their credit decision.

A 1.7% adverse-resolution rate against the national self-storage benchmark of 1.1% tells credit committees to scrutinize revenue projections and coverage assumptions closely on Illinois deals in this class. A rigorous third-party feasibility study — built on documented demand, defensible pricing, and stressed coverage — carries meaningful weight in that underwriting conversation, particularly at an average loan size of $1.4 million across 82 loans.
Every Illinois self-storage project we underwrite follows the same lender ready process: independent market analysis, site and technical review, and financial projections tested against SBA SOP 50 10 8 standards. Our SBA feasibility study consultants guide explains scope, timing, deliverables, and what lenders and CDCs expect in the report.
Illinois projects often fit SBA 504 where owner-occupied real estate anchors the deal, with the 50/40/10 structure delivering up to 90 percent financing at a fixed debenture rate, while SBA 7(a) covers acquisitions, working capital, and equipment. From July 4, 2026 eligible borrowers can combine 7(a) and 504 for up to $10 million in total program credit.
Illinois holds roughly 1,558 facilities and 55.6 million square feet, 4.35 square feet per resident against a 5.4 national average, while Midwest stabilized occupancy of 77.9 percent posted the strongest regional gain in late 2025, the rare combination where supply analysis can support new development; Live Oak Bank runs a dedicated national vertical.
