A buried provision in Indiana's HB1003 lets certain design professionals skip state plan review entirely—cutting weeks from project timelines.
Most Indiana manufacturers don't know that a new state law gives qualified design professionals the power to bypass traditional plan review altogether. Starting July 1, 2027, HB1003 creates a self-certification pathway that could shorten project timelines by weeks or months—and reduce carrying costs during the review process.
Section 417 of HB1003 (codified in IC 22-15-3.5) establishes a self-certification option for Class 1 construction projects. Here's how it works: An Indiana-registered design professional who meets specific qualifications can certify that their building plans comply with all applicable Indiana building codes. Once submitted, that certification triggers a next-business-day design release—no state plan review required.
The state still receives the plans and certification. But the traditional review cycle, which can stretch weeks or months depending on workload and plan complexity, is eliminated.
The design professional must meet four criteria:
This is a meaningful bar. It's not available to every designer or architect. But for established firms with a track record in Indiana, it's accessible.
Manufacturing facilities often involve specialized structures—warehouses, production buildings, utility systems—that trigger plan review. Delays in design approval directly delay construction starts, which delays occupancy and revenue. Every week of review delay is a week of carrying costs: consultant fees, financing costs, and opportunity cost.
For a small to mid-sized manufacturer planning a new facility or major renovation, cutting 4–12 weeks from the approval timeline can mean real money. The self-certification pathway shifts responsibility to the design professional (backed by their insurance and professional standing) rather than the state, allowing faster project advancement for firms working with qualified professionals.
The provision becomes effective July 1, 2027. Manufacturers and their design teams should begin planning now if they have projects in the pipeline for late 2027 or beyond. Confirming that your architect or engineer meets the five-year experience, five-project, and insurance requirements is a straightforward conversation—and could shape your project timeline.
This is not a blanket exemption from code compliance. Self-certification still means full compliance with Indiana building codes. What changes is the approval mechanism: the state trusts the professional's judgment rather than conducting its own review.
For manufacturers evaluating design partners or planning facility projects, understanding this pathway is part of informed decision-making. A qualified design professional can now offer a genuine timeline advantage that wasn't available before.
