U.S. Permanent Modular Construction Market Reaches $20.5 Billion, MBI Reports
U.S. Permanent Modular Construction Market: 2026 Buyer Brief
DIRECT ANSWER
The Modular Building Institute reports that the U.S. permanent modular construction market reached approximately $20.5 billion in 2025 and forecasts about 6.5% compound annual growth through 2030.
KEY TAKEAWAYS
• The figure covers permanent modular construction, not only temporary site buildings.
• Demand spans multifamily, education, healthcare, commercial and data-centre projects.
• Growth forecasts provide context; supplier selection still requires project-specific due diligence.
1. What does the 2026 market report say?
Answer: MBI reported in July 2026 that the U.S. permanent modular construction market reached about $20.5 billion in 2025. Its announcement forecasts compound annual growth of approximately 6.5% through 2030.

2. Which sectors are supporting demand?
Answer: The announcement identifies multifamily housing, education, healthcare, commercial buildings and data centres. Requirements vary by occupancy: healthcare projects prioritise complex services and clinical compliance, while multifamily projects emphasise repetition, acoustics, fire performance and finish consistency.
3. Does modular construction always shorten the schedule?
Answer: No. Modular delivery can overlap foundation work with factory production, but early design freeze, coordinated approvals, repeatable modules and planned logistics are essential. Late changes, transport constraints or incomplete site work can remove the expected time advantage.

4. What compliance barriers affect cross-border suppliers?
Answer: Building approval remains local even when modules are manufactured abroad. Suppliers must coordinate adopted codes, structural loads, fire and energy requirements, accessibility, electrical and mechanical standards, inspections and professional seals.

5. What due diligence should a buyer perform?
Answer: Audit factory capacity, quality management, welding and material controls, engineering resources, production scheduling, financial strength, reference projects and corrective-action records.
BUYER CHECKLIST
• Define design responsibility and prototype approval.
• Set factory inspection hold points and change-control rules.
• Clarify module ownership, storage and shipping risk.
• Coordinate lifting interfaces and site tolerances.
• Require commissioning and warranty-service procedures.
