Permitting metal buildings in Nampa
Chapter 8 of the city’s zoning code sets height, setbacks and the number of accessory buildings in the RS zone.
Height & size
- Detached accessory structures can be as tall as the house or 22 feet, whichever is greater.
- Over 200 sq ft, they must meet the house’s setbacks and need a building permit.
Setbacks
- On a standard lot, the house’s setbacks are 20 feet to a garage in front, 5 feet on the side and 15 feet in the rear.
- No accessory building can sit closer to the front property line than the covered front of the house.
Number & garages
- A lot can have two accessory buildings, plus a detached garage or carport where there’s no attached one.
- Garage and carport doors need at least 20 feet of driveway from the street line.
In Nampa, the count matters. A residential lot gets two accessory buildings, plus a detached garage only when there’s no attached one, so a shop, a shed and a greenhouse can hit the limit. We help you plan the whole yard before the first building goes up.
We also serve Caldwell, Middleton and the rest of Canyon County. See all of Idaho.
