The pricing model is primarily based on a monthly lease rate per unit, which varies by size, configuration, and lease duration (longer terms receive lower rates). This base rate typically accounts for 60-70% of the total invoice cost. The remainder is comprised of one-time fees and recurring charges. One-time fees include delivery, installation/setup, and final removal. These are heavily influenced by distance from the supplier depot and site complexity.
Recurring ancillary charges often include damage waivers, maintenance plans, and rental of VAPS (Value-Added Products & Services) such as furniture, stairs/ramps, and sanitation services. Suppliers are increasingly focused on driving VAPS revenue, as it improves profitability per unit. The most volatile cost elements passed through to customers are typically embedded in delivery fees or applied as surcharges.

Demand in North Carolina is High and projected to remain strong. This is fueled by a confluence of major public infrastructure projects, sustained commercial real-estate development in the Charlotte and Research Triangle Park (RTP) metro areas, and significant new manufacturing investments (EVs, batteries, biotech). All Tier 1 suppliers have a dense network of depots across the state, ensuring High local capacity and competitive delivery times. The state's favorable business climate is a net positive, though localized construction labor shortages could indirectly extend project timelines, thereby increasing the duration of modular office rentals.
| Risk Category | Rating | Justification |
|---|---|---|
| Supply Risk | Low | Highly consolidated, but multiple large, well-capitalized suppliers with vast fleets mitigate risk of service failure. |
| Price Volatility | Medium | Base rental rates are stable under contract, but fuel/material surcharges and spot-market pricing can fluctuate significantly. |
| ESG Scrutiny | Low | Growing interest in unit energy efficiency and end-of-life disposal, but not yet a primary driver of regulatory or reputational risk. |
| Geopolitical Risk | Low | Service is inherently local/regional. Supply chains for new unit manufacturing have some exposure but are largely domestic. |
| Technology Obsolescence | Low | The core product is mature. Innovation is incremental and focused on add-on services rather than the core structure. |
