Tiny Home & Park Model Information While there is an official definition of a tiny home, tiny homes and park models are generally thought of as small homes, typically sized under 400 square feet. While they can be built on foundations, most tiny homes are built on trailer frames or a chassis. If a tiny home is to be placed on a foundation, then it is treated the same as a Modular Home; all permitting requirements are the same as a Modular Home, and it must be constructed and inspected to the state‐ adopted codes. However, if the tiny home or park model remains on a chassis, then it is considered a recreational vehicle (RV) and falls under all the requirements and jurisdiction of the Idaho Transportation Department (ITD). Additionally, some local jurisdictions may have zoning restrictions on where tiny homes may be located, which may differ from a H U D Manufactured Home or IRC Modular Home. Additional Information Always perform your due diligence in hiring a contractor to perform work within or around your home. Electricians, plumbers, mechanical contractors, and manufactured home installers & manufactured home retailers must all be licensed by DOPL to perform their trades within the state of Idaho.

Additionally, all contractors, including those installing foundations, must be registered with the Idaho Division of Occupational and Professional Licenses (IDOPL).

What permits will need to be obtained, and from what agencies? For the installation of a HUD Manufactured Home - the Idaho licensed installer or homeowner must obtain an Installation Permit; and for a New Home, an Installation Tag** permit (is also required) before the installation. The installation permit is obtained from the local jurisdiction; if there is no local jurisdiction / building department, then the installation permit is obtained from DOPL. The Installation Tag permit is always obtained from DOPL, regardless of jurisdiction. An Installation Tag is not a tag, rather a MFG assigned to that new home; DOPL provides the location data to HUD. An Installation Tag is not applicable for previously occupied Manufactured Homes. All New manufactured homes must be installed in accordance with the Manufacturer’s Approved Installation Instructions. All Used mobile and manufactured homes shall be installed in accordance with the Idaho Manufactured Home Installation Standard. Such inspections shall be recorded on an inspection record document and a copy shall be provided to the homeowner upon completion of the inspection. Permitting Requirements (cont.) Permits for on‐site mechanical work and electrical / plumbing hookups must be obtained by DOPL‐licensed contractors in those trades that perform that work. For Idaho‐approved Modular Buildings, the following permits are required: A foundation permit must be obtained from the local jurisdiction. If there is no local jurisdiction, then this permit is not required. Permits for on‐site mechanical work and electrical / plumbing hookups must be obtained. If there is no local jurisdiction, then these permits are obtained from DOPL. Depending on the jurisdiction in which the home is being placed, additional permits and inspections may be required. Check with your local (city or county) Building Department for more information, including any zoning requirements. ***On state‐owned projects, for Manufactured Homes & Modular Homes, ALL permitting is done through DOPL, regardless of location within Idaho (other than Federal land, or military bases, unless requested). Flip page over for more information → Manufactured Homes and Modular Buildings—what sets them apart? A Manufactured Home, and a residential Modular Building, both constructed within a factory and then delivered to the home site, look very similar at first glance. In fact, there may be such subtle differences that most people may not be able to tell them apart at all. So, what makes them different? The answer is how these structures are built. Manufactured Homes are built to the federal HUD Standards, and Modular buildings, whether residential or commercial, are built to state‐adopted codes, such as the International Residential Code (IRC) or the International Building Code (IBC), among other adopted codes.
