Government / Military Modular Building — Prices, Sizes and Delivery

The government / military modular building is one of the most requested configurations we quote, and it is also one of the most inconsistently priced across the industry. Suppliers publish a per-square-foot figure, leave out foundation, freight, crane and permitting, and the number a buyer eventually pays lands well above what they planned around. We publish the unit price and the site costs separately so the comparison is honest.

New versus used versus rental

New units carry full warranty, current code compliance and the finish level you specify. Used and refurbished inventory typically runs forty to sixty percent below new, with the trade-off being available configurations rather than condition — a refurbished unit is stripped, inspected, repaired and re-finished, but you take the floor plan that exists. Rental makes sense under roughly eighteen months of use; past that point, cumulative rent generally exceeds purchase price and you own nothing at the end. Run the arithmetic on your actual duration before defaulting to rental because the monthly number feels smaller.

What actually drives the price

Size is the obvious variable, but it is rarely the one that moves a quote the most. Finish level, mechanical capacity, code requirements in your jurisdiction, and site conditions all shift the total more than a few extra square feet. A unit destined for a high-wind coastal county needs impact-rated openings and engineered tie-downs. A unit for a site with no municipal sewer needs a septic system. Neither of those is visible in a per-square-foot figure, which is exactly why we break them out.

Lead time and why it is a range

We quote 30 to 90 days as a production window rather than a delivery date, and the reason is supply and demand. Factory queue depth changes weekly. Material lead times on steel, windows and finish goods have tightened this year and seasonal demand compresses the calendar heading into spring. A slot confirmed today holds at the window we quote. A slot considered for six weeks usually reprices, because the block it was going into has filled.
