Nampa Idaho Shed, Fence, and Deck Permit Guide

Nampa requires permits for many residential improvements, including fences, decks, patios, carports, storage structures, and accessory structures with permanent utilities, while exempting some small detached storage buildings.

Permit takeaway

Nampa lists one-story structures such as garages, decks, covered patios, carports, and residential storage structures as work requiring permits, with an exemption for detached storage buildings under 200 square feet and not over 12 feet high.

Zoning and placement

The city advises homeowners to confirm accessory-structure setbacks and easements with Planning and Zoning, especially before relying on a small-shed exemption.

Building and trade review

Accessory structures of any size require a building permit and approved permanent footing or foundation when permanent electrical wiring, plumbing, or HVAC systems are installed.

Call before applying when

Call before building a fence, deck more than 12 inches high, shed in a floodplain, accessory structure with utilities, or pergola, gazebo, carport, or patio cover.
