Top 5 Frequently Asked Questions

We know that choosing the right modular home or construction trailer comes with a lot of questions—and we’re here to make things simple. In this section, we’ve gathered the top five questions we hear most often from customers, along with clear, straightforward answers.

Do I need a permit for a Modular Home?

Yes. Even if the home has wheels, a permit is still required. The specific requirements will vary, depending on the municipality.

Are your modular homes mortgageable?

If you own the property that the home is being built on, a construction loan may be an option. This could then, in many instances, be converted into a mortgage upon occupancy.

What is the difference between a Modular Home and a Mobile Home?

The building code is different, as a modular home (CSA A277) is a permanent residence, while a mobile home (CSA Z240) can usually only be placed in a mobile home park.

Learn more about the difference between a modular and mobile home.

Do your Office Trailers come with heating and cooling?

Yes. Baseboard heaters and through-wall air conditioning are included as standard.

Can I move an Office Trailer unit that I am renting on my own?

It would be advised to call us so that we can make a recommendation based on your specific situation in order to make a proper determination.

Live comfortably or work efficiently - we can help with both.
