Deck Construction · Power County, Idaho
In Idaho, a Deck Construction requires a building permit.
The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit. Plans are reviewed under the Statewide code (IRC 2024); apply through Power County Building Administration before work begins.

Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).

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.
Regardless of the state permit rule above, Power County still enforces property-line setbacks and local zoning for your Deck Construction. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Power County Building Administration before building.
Idaho generally favors property rights with relaxed state-level oversight, meaning agricultural zoning often dominates outside of major hubs like Boise. Fortunately, Idaho maintains relatively builder-friendly regulations, keeping base permit fees competitive.
