It depends on the size and options included with your BOSS Tiny house. Most counties allow for the construction of one 120 sqft structure without applying for a building permit. Be sure to check local regulations by contacting your local building department before ordering.

1. Find out if you need a permit (see questions below) 2. If you need a permit, talk to us about our permit package 3. Obtain your site plan and local building codes 4. Take BOSS Permit Package (and any supplementary information) to your local building department for a permit

For those that require permitting we offer a Permit Package (for an additional fee). In our Permit Package you will be provided engineer-stamped structural drawings, foundation details, and your BOSS Tiny House mapped on your site plan.

Tip: If your city requires a permit, opt for an electrical-only permit, rather than a full building permit, as it is usually much simpler to obtain.

  • Is there a certain size or square footage where a building permit is required?
  • What is your zoning and allowed building forms?
  • Is an engineer-stamped plan set required to pull a permit?
  • Is there a limit to the number of structures you can add to property?
  • What is the max lot coverage for all structures?
  • Any wall or roof height limitations?
  • What is the required distance between structures on your property?
  • What are your setbacks (distance off the property line to the new structure)?
  • Any special easements (utility, cable, access roads, open space, corner lot) that affect where your Tiny house can go?

Do not place an order without going through the permitting process. We recommend having discussions with a BOSS team member and having a permit before placing an order.

We offer a 50% money back guarantee for those who do not get approved after three trials.
