Most-asked questions

How much does a used modular building cost?

As a benchmark, a used 24’×40′ classroom runs about $65,000 plus about $18,000 for delivery and installation, and a used 24’×60′ about $115,000 plus about $24,000. Site work, ramps and permits are extra. Compare prices.

How fast can I get a modular building?

A used building that’s already built can be delivered in days to weeks. A new build takes months. Permits and site work usually set the real timeline. See the full timeline.

Is it cheaper to rent or buy?

Renting fits short-term needs. If you need the space for several years, buying a used building usually costs less overall. Compare rent vs. buy.

What do I need to sell a used modular building?

Start with proof of ownership and the building’s state approval records. Our guide lists every document. See the document checklist.
