RV garage cost in the East Valley (2026)

Quick answer

Plan on $95 to $135 per square foot for a stucco RV garage that matches the house, and $130 to $165 for an insulated shop with AC. A 20x40 stucco RV garage is about $76,000 to $108,000. A 14 ft door usually means an 18 to 22 foot roof peak, which changes where it can sit.

RV garage cost calculator

Pick a size and finish. The range uses the same per square foot rates as our published 2026 cost table, so the math always matches.

What are you planning?
300 to 1,200 sq ft. Under 500 sq ft uses the higher small-casita rate.
Finish level
A bigger kitchen or a second bath moves you up a finish band. High-end is the top band.
Utility runs (power, water, sewer)
Examples: 20x40 is 800 sq ft. 24x45 is 1,080. 24x50 is 1,200.

    What we check against:

    • Queen Creek: a detached accessory building over 15 feet tall must meet the zoning district's normal side and rear setbacks.
    • Chandler: detached accessory buildings other than ADUs are limited to 15 feet tall and must meet the district's side and rear setbacks.
    • Mesa: a detached accessory building over 15 feet tall at the peak must meet the district's normal setbacks and generally cannot be taller than your house's roof peak without a Special Use Permit.
    • Unincorporated Maricopa County: detached accessory buildings may sit in the required side or rear yard as close as 3 feet to the lot line, as long as they cover no more than 30% of that yard.
    • Gilbert, the Town of San Tan Valley and unincorporated Pinal County: we have not confirmed current numbers, so we tell you which office to ask.

    Your HOA and any PAD zoning can be stricter.

    We only use this to look up your zoning.

    The 14 ft door

    Many fifth wheels are around 13 ft 6 in tall, so owners usually plan a 14 ft door. In our line items, a 14 ft door and jackshaft opener runs $4,800 to $7,500. Measure your rig, including AC units and antennas, before you design.

    A 14-foot RV door usually means 16 to 18 foot walls and an 18 to 22 foot roof peak. That is taller than the reduced-setback height limit in Queen Creek, Chandler and Mesa. So the door decides the setbacks. See the height drawing.

    Metal vs stucco RV garages

    Stucco that matches the house is what most HOAs ask for. Red-iron steel can work on a no-HOA lot if the city or county allows it.

    Steel kits alone run about $11 to $18 per sq ft. The slab, doors, electric and erection are most of the cost, so ask for a full turnkey quote.

    RV garage with living quarters

    Living quarters turn part of the project into a casita (an ADU), with its own rules and a higher cost per foot. The living space and the RV bay are treated differently by the city. See RV garage with a casita for costs and the setback rules.

    Frequently asked questions

    How much does it cost to build an RV garage in Arizona?

    In the East Valley, our 2026 planning rates are $95 to $135 per sq ft for stucco and $130 to $165 for an insulated shop with AC. A 24x50 stucco RV garage is about $114,000 to $162,000. These are planning ranges, not quotes.

    How much is a 20x40 RV garage?

    About $76,000 to $108,000 in stucco at our 2026 rates, or $104,000 to $132,000 insulated with AC.

    Is a metal RV garage cheaper?

    Often the kit is, but the slab, doors, electric and erection are most of the cost. We have not confirmed a local turnkey steel price.

    Can an RV garage use the 5-foot casita setback?

    No source we checked says so. The 5-foot ADU setback applies to the living unit. In Chandler and Mesa, a garage attached to an ADU must meet the normal setbacks.
