Concrete RV Pad Cost in Spokane: Size, Thickness and Where You Can Park

An RV, fifth wheel or boat trailer parked on grass or thin gravel ruts the yard, and a standard 4-inch driveway can crack under the jacks. A dedicated concrete RV pad fixes that. Here's what one costs in the Spokane area in 2026, how thick it should be, and the parking rules in Spokane, Spokane Valley and Liberty Lake that decide where it can go.

The short answer

Pricing depends on pad size, thickness, site prep, and finish. Call (509) 350-2016 or request a free quote at https://raven509.com/request-quote.

We price every pad from your address, because site prep and access move the number more than anything else.

RV pad cost by size

For a 6-inch pad with rebar on a 6-inch crushed-stone base:

• 10x30 (300 sq ft), camper van or short trailer
• 10x40 (400 sq ft), travel trailer
• 12x45 (540 sq ft), fifth wheel or motorhome
• 12x50 (600 sq ft), long fifth wheel
• 14x55 (770 sq ft), large motorhome or toy hauler

Pricing depends on pad size, thickness, site prep, and finish. Call (509) 350-2016 or request a free quote at https://raven509.com/request-quote.

Measure your rig with the slides out and leave room to walk around it.

How thick should an RV pad be?

• 4 inches is the standard for walkways and car driveways. 5 to 6 inches for RVs, boats and work trucks
• 6 inches minimum for travel trailers and 7 to 8 inches for fifth wheels and Class A motorhomes
• 4,000 PSI concrete with #4 rebar at 18 inches each way is the spec
• Base: 6 inches of crushed stone, versus 4 inches for a patio
• Slope and joints: 1/8 to 1/4 inch per foot of fall away from the house and saw-cut joints every 10 to 12 feet

For more on thickness, see our shop slab thickness guide. A 12x45 pad at 6 inches is 270 cubic feet, or 10 cubic yards. Our concrete cost per yard guide covers ready-mix and short-load pricing.

Built for Eastern Washington freeze-thaw

Liberty Lake's construction design criteria rate concrete weathering as severe and set the frost line at 24 inches, and the same freeze-thaw cycles hit the whole Spokane area. 5 to 7% air entrainment is used for any exterior pour in freeze-thaw country. We use air-entrained mix, a compacted base and drainage away from the pad so water doesn't sit under it and heave it.

Where you can put an RV pad

The pad is only useful if you're allowed to park there. Check your jurisdiction first:

• City of Spokane: RVs and utility trailers can't be stored in the first 20 feet from the front lot line or a side-street lot line. In RA and R1 zones no more than 40% of the front yard can be paved or used for vehicles (20% in R2 and denser zones). Driveways and parking areas need an all-weather surface, but the code lets RVs and trailers be stored on unpaved ground (SMC 17C.230.145)
• City of Spokane: an RV can't be lived in on private property for more than 14 days in a 12-month period (SMC 17C.319.200)
• Spokane Valley: an RV can't sit in the required front yard setback more than 15 consecutive days or 30 days total in any 12 months (SVMC 19.65). Driveways and parking areas must be paved, with asphalt, concrete, grasscrete or pavers allowed for homes (SVMC 22.50)
• Liberty Lake: the City's residential permit guide lists sidewalks and driveways as not needing a building permit, but work in the street right-of-way needs an approach permit. See our Liberty Lake concrete page
• HOAs: many restrict RV parking regardless of city rules

Add-ons worth planning before the pour

• Approach or apron: where most cracking starts, as the trailer crosses from the driveway. Ours get thickened concrete at the transition
• Electrical conduit or a sewer cleanout: a conduit pre-stub during the pour is far cheaper than cutting concrete later. Wiring and plumbing hookups are extra and done by licensed trades
• Tear-out: old concrete in Spokane. Pricing depends on pad size, thickness, site prep, and finish. Call (509) 350-2016 or request a free quote at https://raven509.com/request-quote.
• A cover later: if you might add an RV shop or pole building, we can pour the pad as the building's slab with footings in the right place

If your existing driveway is cracking where the trailer turns, see our driveway repair vs. replacement guide.
