Do I Need a Permit to Pour Concrete in Idaho?
Concrete and driveway permit requirements. When flatwork needs a permit, right-of-way bonds, and drainage rules.
Only if it connects to the street, modifies drainage, or is a structural element.
Idaho-specific rules
Adopted code: 2020 Idaho Residential Code (based on the 2018 IRC with Idaho amendments) — the statewide baseline under the Idaho Building Code Act, effective January 1, 2021. Footings, foundations, and structural flatwork are governed by the adopted code's foundation provisions; foundation and footing work is generally permit-triggering under the adopted code even where surface flatwork like a driveway or walkway may not be — confirm with your local building department.
When You Don't Need a Permit
Simple concrete flatwork on your own property — a backyard patio, a walkway, or a small pad — typically does not require a building permit in most cities, as long as it doesn't alter drainage patterns or connect to the public right-of-way.
When You Do Need a Permit
A permit is required for: new driveways or driveway widenings (curb cut modification), sidewalk work in the public right-of-way, any concrete that changes drainage patterns, and structural concrete (retaining walls, foundations). Driveway permits may also require a refundable right-of-way bond ($500-$2,000).
Drainage Is Key
The biggest issue with concrete work isn't the concrete itself — it's drainage. Most cities prohibit directing water runoff onto neighboring properties. If your new concrete changes how water flows on your lot, you may need a drainage plan even for otherwise exempt work.
ADA at the Sidewalk
If your driveway crosses a public sidewalk, the approach must meet ADA slope requirements. This is enforced during the permit process and is a common reason driveway permits are revised.
Backyard patio? Probably no permit. Driveway or anything touching the street? Yes. Always check drainage impact.
