Building a custom home from the ground up requires comprehensive oversight from the city. This involves a master building permit that encompasses zoning, foundation, framing, plumbing, electrical, and HVAC. It is the most heavily regulated residential project, ensuring the dwelling is safe for human habitation.
With a growing population of around 25,483 residents, Cassia County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
Code Compliance & Inspections
Because of severe winter weather in Idaho, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Idaho State Building Code.
Local Zoning & Setbacks in Cassia County
Regardless of the state permit rule above, Cassia County still enforces property-line setbacks and local zoning for your New Home Construction. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Cassia County Courthouse before building.
