What people build in Kennewick
The largest of the Tri-Cities, where accessory buildings in residential zones top out at 20 feet.
Shops & garages
Detached accessory buildings in residential districts can be up to 20 feet tall, measured to the highest point of the roof.
Alley lots
A detached building can sit right on the rear line when that line backs onto an alley, canal right-of-way or railroad right-of-way.
Pole buildings
Pole buildings need a building permit but no separate land use permit.
Small sheds
One-story sheds up to 200 sq ft need no building permit, but still have to meet setbacks and stay off easements.
We work in tubular steel, cold-formed steel, steel truss and red iron. See what a steel building costs.
Permitting metal buildings in Kennewick
Kennewick measures accessory building height to the highest point of the roof, not the midpoint of a gable.
Setbacks
- At least 5 feet from side and rear lines, unless the rear line backs onto an alley, canal or railroad right-of-way.
- Nothing can be built on or over an easement, including eaves and footings.
Spacing
- In residential districts, 10 feet from any other building on the lot, or 4 feet if built to the International Building Code.
- No accessory building within 10 feet of the centerline of a window in a home on the same lot or the next one.
Footings
- Footings go 24 inches deep for frost.
- Light-frame buildings up to 600 sq ft, or other construction up to 400 sq ft, with eaves under 10 feet can use a shallower footing.
In Kennewick, a 20-foot limit means watching the peak. Height is measured to the highest point of the roof, so a taller sidewall means a lower pitch. We’ll balance door height and roof pitch to stay under 20 feet.
Plot plans are drawn at 1 inch to 20 feet and show easements, existing buildings and distances to property lines. Outside city limits, Benton County rules apply. See all of Washington.
