What should I know before buying a modular building?

  • Determine what type of activities you plan on doing inside your modular building. This will dictate the type of occupancy or code a building is built too (office, educational, etc.).
  • Determine how long you will need to use your modular building. Short term? Long Term? Unknown?
  • Contact the local building department and ask what type of permits will be required to install a modular building. Secure all permits before ordering the building.
  • Ask the local building department if they require ADA access and what type of foundation (temporary or permanent) will be required.
  • Contact MBC for further information.

How long does it take to build and install a new modular building?

Project details, complexity, plan approvals, permit process and options all determine the time frame of a modular building project. We have completed projects in as little as 45 days and as long as 9 months.  In most cases, modular construction saves between 30-50% over the traditional “brick and mortar” (site built) construction.

What do I need to do in order to prepare for delivery of a modular building?

  • MBC recommends preparing a building “pad” which extends at least 5’ away from the footprint of the building. The “pad” can be dirt, decomposed granite “DG”, asphalt or concrete.
  • The pad should be flat, level within 2% in each direction and easily accessible for a freight truck delivery.
  • Stake the four corners of the building on the pad before delivery.
  • Utilities such as water, sewer, and electricity should be clearly marked or staked prior to delivery.
  • For more information on delivery preparation please contact your MBC representative today.
