Airway Heights permit rules for concrete

Airway Heights runs its own building department (1149 S Garfield Rd, 509-244-5514), separate from Spokane County. From the City's published rules:

• Paved driveways need a permit. The City lists driveway installation as permitted work and sends you to the Public Works Department for the requirements
• Garages always need a permit, including any alteration, enlargement or repair of an existing garage
• Detached sheds and storage buildings need a permit over 200 sq ft
• Patios poured at grade don't need a permit unless excavation or fill passes the City's thresholds or you add a roof over them
• Retaining walls need a permit over 4 feet, measured from the bottom of the footing to the top of the wall
• Commercial projects need a pre-application conference with the City first

The City also posts a notice that permit reviews are running behind because of staff shortages, so get your application in early if you're on a deadline. We'll tell you up front which pieces of your project need a permit.

The design numbers your slab and footings have to meet

Airway Heights Municipal Code 15.03.020 sets the City's design criteria:

• Frost line depth: 24 inches, so footings go at least that deep
• Weathering: severe, which is why exterior flatwork here should be poured with an air-entrained mix built for freeze-thaw cycles
• Ground snow load: 39 psf, with a 30 psf minimum roof snow load
• Air freezing index: 1,232

Building a shop on that slab?

We build the foundation and the building together, so the anchor bolts land where the steel needs them. Read what a 30x40 or 40x60 metal shop with a slab really costs, or see our steel building and pole building services. For floor finishes, compare epoxy and polyaspartic garage floors.
