How a factory, builder, or developer chooses to navigate building codes can determine their profit, timeline and ability to innovate.
Most modular factories lean heavily on prescriptive codes that spell everything out — sizes, materials, thicknesses, installation methods, etc. Consistency and repeatability are king, and prescriptive codes reduce arguments with inspectors, streamline approvals and provide a clear production roadmap. They help keep lines moving.
But clarity can become an impediment to progress. If a factory wants to introduce a new wall system, a better insulation package, or automation, prescriptive codes don’t bend easily. They were written for control, not innovation.
On the other side of the spectrum are performancebased codes. These don’t tell you how to build — they tell you how your buildings must perform. Energy efficiency, structural integrity, fire resistance. Outcome matters more than method.
Factories experimenting with robotics, new materials, or advanced building systems can use performance-based codes to leap forward. This opens the door to smarter design, better energy performance and lower long-term costs.
But there’s a catch. To prove performance you need engineering, testing and documentation — a level of expertise and patience not every company has. And you may need to convince an inspector that your approach works. All this adds time, cost and uncertainty.
The reality is that most factories operate in a hybrid mindset. They lean on prescriptive codes for production efficiency, but selectively adopt performance-based approaches when they need a competitive edge.
Not surprisingly, the strongest proponents of performance-based solutions are large, wellcapitalized factories that invest in automation, AI-driven processes, or advanced materials. They have the resources to test, validate and defend their methods. Small factories, or those struggling with margins, tend to stay safely within prescriptive boundaries.
Then there’s the builder or developer. Many don’t realize how the compliance path chosen impacts cost, performance and long-term value. This disconnect can create friction, change orders and costly misunderstandings before a module ever leaves the factory.
The approach chosen can also impact profit.
Prescriptive codes can inflate costs by forcing the use of materials or methods that exceed what’s needed, while the performance path can increase engineering and approval costs. In an industry where a 1% swing in profit can make or break a year, that’s not a small issue.
Around the world, performance-based codes are gaining ground. Australia, Canada and the UK already embrace them in key areas like energy efficiency and structural design. In the US, green building initiatives, resilience standards and sustainability goals are quietly pushing jurisdictions toward performance-based thinking.
This is a strategic inflection point. Factories that learn how to operate in both worlds — leveraging prescriptive efficiency while mastering performancebased innovation — will have a big advantage.
Those that don’t may end up producing yesterday’s solutions in a market demanding tomorrow’s performance.
Most factory owners and builders think they’re in the construction business. But they’re actually in the compliance business first. The ones quietly outperforming everyone else are those who understand that the choice of which code to follow, and where, represents strategic leverage.
