Indiana HB1003: New Self-Cert Rule for Construction Plans

A buried provision in HB1003 lets experienced design professionals fast-track plan approval—but only if you meet specific requirements.

Most Indiana construction and trades owners don't realize that a provision tucked into HB1003 will fundamentally change how building plans get approved—and it takes effect July 1, 2027.

The change is straightforward: qualified Indiana-registered design professionals can now self-certify that their Class 1 construction plans comply with all applicable building codes. Once certified, plans get released the next business day—no state plan review required.

Who This Affects

This applies to design professionals (architects, engineers) who meet all of these criteria:

If you work with design consultants who meet these thresholds, this matters to your timeline and cash flow.

Why It Matters

State plan review can take weeks or months. That delay ties up capital, delays contractor mobilization, and pushes project starts backward. For small and mid-sized firms, carrying costs during review periods eat into margins.

Under the new rule, qualifying professionals can self-certify compliance, triggering a next-business-day release. That's a potential elimination of months of waiting—and the associated costs.

The catch: the professional doing the self-certification is taking on the compliance risk. If plans don't actually meet code, that professional's liability insurance is the backstop, not the state. That's why the insurance requirement ($500K/$1M) is built in.

What You Should Know Now

This rule applies only to Class 1 construction. If you're working on other project types, state review still applies as normal.

The provision is codified in Section 417 of HB1003, creating a new chapter at IC 22-15-3.5 (pages 228–229 of the bill text). It becomes effective July 1, 2027, giving design professionals and firms time to prepare systems and verify insurance coverage.

If you regularly partner with design consultants, now is the time to confirm whether they'll qualify. If they do, you can plan for faster approvals starting next summer. If they don't, you may want to discuss a path to qualification or identify firms that do meet the threshold.

For contractors and trades: this won't change how you work day-to-day, but it will change when you can start. Faster plan approval means earlier project starts for clients who use qualifying design professionals.
