A buried provision in Indiana's HB1003 lets qualified design professionals fast-track code approval for Class 1 construction—here's what it means for your timeline and costs.
Most Indiana construction and trades owners don't realize that a provision buried in HB1003 is about to reshape how quickly commercial and public building projects move through the approval process. Starting July 1, 2027, there's a new path to getting design releases that could eliminate weeks—or months—of waiting.
Under Section 417 of HB1003 (pages 228–229), Indiana now allows qualified, registered design professionals to self-certify that their building designs comply with the Indiana Building Code. Instead of submitting plans to the state for review, a design professional can issue a design release themselves—and you can have it the next business day.
This applies to Class 1 construction: commercial buildings, public buildings, and similar structures. It does not apply to residential work.
If you're a general contractor, construction manager, or trades business working on commercial or public projects in Indiana, this matters. So does your architect or engineer—they need to be an Indiana-registered design professional to use this route.
The self-certification option is voluntary. You and your design professional can choose it, or you can stick with traditional state plan review if you prefer.
State plan review can take weeks or months. During that time, your crew may be idle, your financing is tied up, and your project schedule slips. Those carrying costs add up fast on a commercial job.
With self-certification, you get a design release the next business day. That means you can move to permit application and construction much faster—assuming your design professional is confident in the code compliance and willing to stand behind it.
For small and mid-sized commercial projects, this can be the difference between a predictable timeline and one that bleeds money.
The effective date is July 1, 2027. This is not in effect yet, but it's worth planning for now, especially if you have projects in the pipeline.
Your design professional will need to be Indiana-registered and willing to self-certify. Not every firm will do this—it requires confidence in their code knowledge and willingness to take on the liability. Have that conversation early.
Self-certification doesn't eliminate other approvals. You'll still need permits, inspections, and compliance with local codes. What this speeds up is the state design review step.
If the state later finds a code violation in a self-certified design, there are enforcement mechanisms. Your design professional needs to understand that risk.
If you work on Class 1 commercial or public projects, talk to your architect or engineer now about whether self-certification makes sense for your typical work. Understand their comfort level and any additional fees they might charge for taking on that certification responsibility.
