The Problem
The National Association of Home Builders estimates that regulatory requirements add an average of 24.3 percent to the cost of a new single-family home, with permitting delays as a significant contributing factor. That figure is residential, but the structural problem it describes (code compliance overhead and permit process friction driving up project cost) applies across commercial MEP work as well, where multi-jurisdiction complexity and iterative review cycles add their own version of the same burden. Every jurisdiction has its own adopted code edition, local amendments, and permit submission requirements. A firm working across multiple jurisdictions manages those differences manually, tracking which code version applies where, which local amendments modify national standards, and what each jurisdiction requires for a complete submission.
Manual code research is time-intensive and error-prone in ways that aren't always visible until a permit is rejected or a design review reveals an incorrect code reference. An engineer spending three hours researching applicable mechanical code requirements for a project in an unfamiliar jurisdiction is spending three hours that won't appear on an invoice. If the research produces a code interpretation that later gets challenged during plan review, that's additional non-billable revision time on top of the initial investment.
Permit delays compound the problem. When permit submissions are incomplete (missing required calculations, incorrect energy compliance documentation, or jurisdiction-specific form requirements not addressed) the resubmission cycle consumes additional engineering time and delays the project start date. Developers and builders must carry staff costs and overhead during permit delays, a cost that ultimately flows through the project.
What's Driving It
The code research burden reflects two structural issues. First, code requirements change on a rolling basis: adopted editions vary by jurisdiction, local amendments are issued independently, and interpretations of requirements are not always consistent across plan reviewers. Tracking that landscape manually requires ongoing effort that most firms don't have a systematic process for.
Second, permit preparation is treated as a project task rather than a defined workflow. Each engineer assembles the submission based on their understanding of the jurisdiction's requirements, gleaned from prior experience, phone calls to the building department, and whatever documentation the firm has retained from prior projects in that area. When that knowledge isn't current or complete, the submission reflects those gaps.
The result is a process that is slower than it needs to be, more variable than it should be, and more dependent on individual experience than is sustainable as project volume scales.
What Resolution Looks Like
Structured AI support in the permitting and code research workflow addresses the knowledge currency problem directly. Current code editions, local amendments, and jurisdiction-specific requirements are maintained in a searchable, up-to-date reference environment. An engineer researching applicable requirements for a project pulls from a verified current source rather than relying on memory or manual searches across multiple code websites.
Permit application completeness checks (comparing the proposed submission against the jurisdiction's documented requirements) reduce resubmission cycles. Energy compliance documentation gets assembled against current standards rather than the version the team last worked with. The engineer still interprets the code and makes the engineering judgments the design requires. What changes is the time spent locating and verifying the inputs those judgments depend on.
For firms managing multiple active projects across different jurisdictions, this workflow improvement has a compounding effect: fewer resubmission cycles, more consistent code references across the team, and permit preparation hours that reflect what the task actually requires rather than the overhead of manual research.
QP works specifically with MEP and AEC firms, which means the code research and permitting workflows we design reflect the jurisdictional complexity, energy compliance requirements, and permit submission standards that MEP engineers navigate, not a generic AEC template adapted to fit.
The Bottom Line
Permitting and code research hours are non-billable, non-negotiable, and invisible in most firm workflows. They don't appear as a category in a project budget until a delay forces the conversation. Firms that treat this as a defined workflow, with current, verified references and a structured preparation process, recover the hours that manual research consumes and reduce the resubmission risk that those delays generate.
The code doesn't get simpler. The jurisdictional variation doesn't go away. What can change is how efficiently your team navigates it.

If your code research process relies on individual engineers tracking jurisdiction requirements from memory, there's a more reliable approach.
