Concrete contractor in Nine Mile Falls, WA, for driveways, patios, shop slabs and foundations. Raven Buildings pours residential and light commercial concrete across Nine Mile Falls, Suncrest and the Lake Spokane shoreline, on both the Spokane County and Stevens County sides of the river.

Concrete work we do around Nine Mile Falls

• Driveways and approaches: new driveways, replacements and the approach where your driveway meets a County road
• Patios and walkways: broom-finish and stamped concrete, including lake-view patios
• Shop and garage slabs: sized for vehicles, lifts, boats and equipment
• Footings and foundations: for shops, pole buildings, steel buildings, homes and additions
• RV and boat pads: thicker slabs for heavy loads

First question: which county is your lot in?

Nine Mile Falls (ZIP 99026) straddles the Spokane River and the Spokane–Stevens county line, so the ZIP code doesn't tell you who issues permits:

• Spokane County parcels: Spokane County Building & Planning handles building permits, and Spokane County Public Works handles road approaches
• Stevens County parcels, including Suncrest: Stevens County Land Services handles building and planning, and Stevens County Public Works handles road approaches
• How we check: we pull your parcel number before we quote, so the footing depth and paperwork match the right county

The local rules your concrete has to meet

• Frost depth, Spokane County side: footings at least 24 inches below finished grade under the City of Spokane / Spokane County joint frost-depth policy
• Frost depth, Stevens County side: the Stevens County building ordinance sets a 30-inch minimum for footings exposed to outside temperatures
• Snow load: Spokane County lists a 39 psf base ground snow load with a 30 psf minimum roof snow load and notes some areas reach 150 psf. Stevens County uses a site-specific figure set by the design engineer and approved by its building official. Either way, that load sizes the footings under any shop or garage we pour for
• Winter: Spokane International Airport, the nearest long-term weather station, averages 132 days a year at or below 32°F (NOAA 1991–2020 normals). Exterior flatwork gets an air-entrained mix, a compacted gravel base, slope away from the house and saw-cut control joints

Nine Mile Falls permits for concrete work

• Approaches, Spokane County side: the County requires an approach permit for any driveway that connects to a County road, including new, widened or relocated approaches. Rural and urban approaches follow different County standards
• Approaches, Stevens County side: new construction along a County road needs a road approach permit from Stevens County Public Works (509-684-4548). The work has to meet the County Engineer's standards and keep road drainage working, and the permit expires if the approach isn't built and passes final inspection within one year of preliminary approval
• Flat slabs on your lot: Spokane County's permit exemption list includes walks and driveways not more than 30 inches above adjacent grade, not over a basement and not part of an accessible route. On the Stevens County side we confirm with Land Services, since its Site Analysis also checks setbacks and plat restrictions
• Foundations: footings and slabs for a new shop, garage or home are reviewed as part of that building's permit. See our Nine Mile Falls metal building page for each county's building permit rules
• Near the water: Washington's Shoreline Management Act covers land within 200 feet of the ordinary high-water mark of shorelines like the Spokane River and Lake Spokane, and both counties' shoreline programs set buffers and setbacks. A lakefront patio or slab needs a shoreline check first, and we flag it on the first visit

What a concrete patio costs

Raven's going rate for a concrete patio, including site prep and the pour, is about $12 to $20 per sq ft for broom finish and $18 to $30 per sq ft for stamped. Where your job lands in that range depends on the size and whether we need a pump to reach the spot, which comes up often on sloped lake lots. Our patio cost guide and our stamped concrete vs. pavers comparison go deeper.
