What type of modular building do I need?

People seek modular building space for a seemingly endless range of reasons, many of which require quick action. Here’s a quick overview of the modular buildings we provide. 

  • Container offices are ground-level, on-site solutions ideal for immediate needs. They’re ISO certified, equipped with heat and AC, and secure, as they have fully welded weather-resistant steel corrugated exteriors and window guards made of tamper-proof screws. 
  • Mobile office trailers are cost-efficient, convenient answers to many temporary office needs. Williams Scotsman offers a wide selection of sizes and floor plans, filling a variety of portable office space needs. 
  • Section modular offices provide double the square footage of our standard mobile office trailers when you have a larger footprint to work with.
  • Panelized & stackable offices (up to three stories) are a great option for an even more sophisticated solution. These flexible, prewired offices feature panelized walls that allow for custom design configurations, helping customers overcome obstacles such as footprint constraints. 
  • Sales offices provide an attractive and immediate on-site presence and can be tailored to your specific need
  • Portable classrooms are an ideal solution when you need additional educational space for students due to aging and outdated facilities, overcrowded classrooms, growing student populations and shifting demographics.

Do I need to get a permit for my modular building solution?

It depends. Permitting requirements vary and are your responsibility to obtain. Contact your local building department to determine what is required in your area.

What type of insurance do I need for my modular solution?

As part of your lease agreement, you are required to obtain General Liability and Property Insurance. For your convenience, we offer a General Liability Program, administered through Allen Insurance Group, and a Property Damage Waiver Program that satisfy these insurance needs. Both programs are available at an additional cost to your monthly rental fee. You can find out more information on these programs here.

What type of routine maintenance do I need to perform?

You are responsible for routine janitorial services and maintaining the general cleanliness of the unit. If the building has gutters, keep them free of debris. You are responsible for proper site drainage around the building and damage, deterioration or contamination of the unit due to water infiltration or exposure is not considered ordinary wear and tear. If a water leak occurs, it is your responsibility to notify Williams Scotsman immediately. Keep the unit properly ventilated. Air conditioning filters should be changed every 30 days. The evaporator coil, condenser coil and HVAC refrigerant should be checked, cleaned and filled as needed. All other air conditioning maintenance should be performed by trained and qualified HVAC technicians only. For additional information, please refer to our Service Guide.
