FAQs About Office Trailers for Sale 

What size generator is needed to run an office trailer? 

• While this will somewhat depend on exactly what accessories you have on your office trailer and how much power they consume, a 6- to 8-kilowatt generator should cover any and all of your power needs. For comparison, a generator meant to provide backup power to a home usually ranges from 7 to 25 kilowatts. More information on selecting generators can be found in our Project Uptime article, Choosing the Right Generator for the Job. 

Does an office trailer require a permit? 

• If you are using your office trailer as a stand-alone structure with its own address, you will definitely require a permit. Depending on the city you find yourself in, your city’s permit office will require different information regarding structural details, location, ADA compliance and more. Before you consider buying a used office trailer, consult your local permit office for more detailed information.
