ABA Clinic Startup Costs in Illinois
Illinois has strong demand and mid-to-higher costs driven by metro Chicago. ABA is covered as Adaptive Behavior Support, with Medicaid enrollment running through the IMPACT system. Here's the honest breakdown of what it takes to open.
What's inside
What it costs in Illinois
Illinois runs mid-to-higher nationally, pulled up by Chicago and its suburbs; downstate (Springfield, Peoria, Champaign) runs meaningfully lower. A lean in-home or telehealth start can open for several thousand dollars plus a payroll cushion. A center-based practice in the Chicago metro commonly runs into six figures once you include payroll before Illinois Medicaid and commercial insurers pay.
Demand is strong statewide. The cost driver is Chicago-area payroll and rent. Budget for the working-capital gap, not just the launch.
Illinois salaries & rent
Payroll is the largest line in any ABA budget. Illinois (Chicago metro) runs above the national average. Illustrative planning ranges, not quotes — verify current local rates.
| Role / item | Illinois typical range |
|---|---|
| BCBA salary | $70k–$100k/yr |
| RBT pay | $19–$27/hr |
| Admin / biller | $38k–$60k/yr |
| Clinic lease (per sq ft, Chicago metro) | $22–$42/sq ft/yr |
| Liability insurance | $1,300–$3,200/yr |
Chicago and the collar counties sit at the top; downstate Illinois runs 20–35% lower on both rent and pay.

| Item | What it covers | Typical range |
|---|---|---|
| Business formation | Illinois LLC, registration with the Secretary of State | $150–$600 |
| EIN | IRS employer ID | Free |
| NPIs | Type 1 (each BCBA) + Type 2 (organization) | Free |
| Equipment | Laptops, tablets, sensory/clinical tools | $1,800–$8,500 |
| Furnishings & build-out | If center-based | $2,500–$28,000 |
| Credentialing | Illinois Medicaid (IMPACT) + managed care + commercial | $1,200–$2,800 |
| One-time subtotal (typical) | ~$6k–$22k | |
IMPACT, Adaptive Behavior Support & the cash gap
Illinois covers ABA as Adaptive Behavior Support (ABS) services, with Medicaid provider enrollment through the IMPACT system run by HFS. After enrollment you contract with the managed-care plans. Credentialing commonly takes 60–120 days per payer, and reimbursements lag after that.
A sample Illinois budget (illustrative)
A small center-based Chicago-area practice — one owner-BCBA, two RBTs, part-time admin, modest leased space — might look like this in year one. Illustrative planning figures, not a quote.
| Category | Year 1 (est.) | |
|---|---|---|
| One-time setup | ~$13,000 | |
| Rent + utilities | 12 mo | ~$34,000 |
| Insurance | annual | ~$5,000 |
| Payroll | owner + 2 RBT + admin | ~$185,000 |
| Software + misc | annual | ~$6,500 |
| Illustrative year-one total | ~$243,500 | |
Higher than Ohio or Georgia, below New York — downstate would run notably lower. Payroll dominates either way.
How to keep costs down in Illinois
- Start in-home or telehealth to skip Chicago rent until revenue is steady.
- Consider downstate markets — rent and salary run well below the Chicago metro.
- Start IMPACT enrollment immediately — it's the longest pole.
- Lease equipment instead of buying to preserve cash.
- Use one all-in-one platform instead of separate data-collection, scheduling, and billing tools.
