Detached Garages & Shops in Flagstaff

Whether you need custom garage designs for a two-car garage, an oversized RV bay, or a full workshop with power and heat, a well-built detached garage structure significantly adds utility and resale value to your property.

Constructing garage buildings in Flagstaff involves more than just a basic kit and a concrete slab. These structures are engineered to handle a 60 psf ground snow load, with footings placed below the 30-inch frost line, and framing rated for 110+ mph winds. A prefab building made for Phoenix simply won't meet plan review requirements here — and for good reason. We specialize in creating robust shops and detached garages designed to endure mountain winters for years to come.

At Executive Builders, we oversee the entire project: from site preparation and engineering to securing permits, concrete pouring, framing, and finish work. If your project requires insulation, heating, wiring for a welder, or plumbing for a utility sink, we integrate those features right from the beginning, avoiding the need for later retrofitting.

Our Process Site walk & layout — We assess setbacks, driveway approach, drainage, and utility runs, and stake out size options for your custom garage designs. This allows you to visualize the footprint before we move into the design phase for your garage buildings. Design & budget — We create plans engineered to withstand Flagstaff's snow, wind, and frost depth, complete with a detailed line-item budget. You'll receive honest estimates comparing stick-built options versus other alternatives for your custom garage designs, as well as for shops and detached garage needs. Permitting — Almost all garage and shop constructions in Flagstaff require a building permit. We compile the necessary package, submit it, and manage the plan review process. Construction — Our services include excavation, footings below frost depth, slab work, framing, roofing, and finishing touches, all under the guidance of a dedicated project lead who provides weekly updates. Final inspection & handoff — We ensure all inspections are passed, doors are adjusted correctly, and conduct a warranty walkthrough to finalize your custom garage designs.

Why Executive Builders Framing is our backbone. We specialize in custom garage designs and frame houses for a living — your garage buildings receive the same straight walls, engineered trusses, and clean rooflines as a custom home. Designed specifically for our region, our shops and detached garage structures support 60 psf snow loads, 30-inch frost footings, and high-wind fastening schedules as standard specifications, not upgrades. Built to complement your home, our garage buildings feature rooflines, siding, and trim that seamlessly match the property — not just a metal box dropped in the yard. Wired and plumbed correctly from the start, our designs include subpanels, 220V circuits, EV chargers, heat, and floor drains integrated into the plan, not added later.
