Episode 72: MBI's $20.5B Modular Market Report

The Modular Building Institute's annual market report puts U.S. permanent modular construction at $20.5 billion in 2025 — about 5.1% of activity in key segments — with a forecast of 6.5% compound annual growth through 2030. For developers, contractors, and capital partners evaluating how hard to lean into industrialized construction, this report is the clearest benchmark available. The numbers tell a story of steady, credible growth — and also of a sector that still hasn't broken through to mainstream share. Key Takeaways: U.S. permanent modular construction hit $20.5 billion in 2025, per MBI's annual industry report. Modular represents approximately 5.1% of construction activity across the key market segments MBI tracks — still a minority method in every major building category. MBI forecasts 6.5% compound annual growth through 2030, which would put the market near $28 billion by decade's end. At that growth rate, modular remains a niche-to-emerging method — meaningful volume, but not a structural shift in how the industry builds. The report tracks relocatable buildings evolving toward "flexible infrastructure" — a repositioning with real implications for how owners underwrite optionality and redeployability. Canadian modular data is tracked in parallel, relevant for cross-border developers in workforce housing and resource-sector construction. 6.5% annual growth against a tightening construction lending environment is the key variable to watch — volume growth that tracks inflation isn't the same as share capture. For capital partners and lenders, the MBI data provides a credible baseline for underwriting modular deal flow — but the 5.1% market share figure is a caution against over-rotating toward modular-specific products before adoption curves accelerate. The more interesting signal is the relocatable-to-flexible-infrastructure migration, which changes the asset optionality story and could attract a different class of institutional capital. Watch whether the 2026 figures show share movement, not just volume growth. Subscribe to Built Different for daily updates on Modular construction reality.
