Lehi deck & beam projects: what to know

Lehi is one of the fastest-growing cities in Utah, and the new construction spreading from Thanksgiving Point up through the Silicon Slopes tech corridor means a lot of homes with builder-basic backyards waiting for a real deck. If you’re on the Traverse Mountain bench, your project has one extra variable most of Utah County doesn’t: wind. Canyon-driven gusts coming off the bench work fasteners loose and punish cheap railing systems, so we spec through-bolted ledger connections, hidden-fastener decking, and railing posts blocked into the frame — not just screwed to the rim joist.

Structure matters just as much underneath. Along the Wasatch Front, decks and exposed beams are designed for a ground snow load of roughly 40 psf, and footings in Utah County need to reach below the ~30-inch frost depth so posts don’t heave through freeze-thaw cycles. We build to the 2021 IRC that Utah has adopted statewide, whether it’s a custom deck anywhere in Utah County or a beam retrofit. Wondering about budget first? Start with our Utah deck cost guide. We also build next door in American Fork, Saratoga Springs, and Highland.

One thing that surprises new Lehi homeowners: Lehi City issues its own building permits through the Lehi City Building Department (lehi-ut.gov) — you don’t go through Utah County. Attached decks, and any deck more than 30 inches above grade, need a permit and inspections. We prepare the drawings and handle the submittal as part of the job, and if your community has an HOA design review (common in Traverse Mountain and other newer Lehi neighborhoods), we build that into the schedule too.

Lehi wood beam installation — interior beams done right

Beam work in Lehi splits into two jobs. Decorative and faux box beams dress up great rooms and vaulted ceilings with no permit required. Structural beams — opening up a wall between the kitchen and living room, or carrying a floor above — need an engineer’s stamp and a Lehi City permit, because that beam is now doing real load-bearing work. We handle both, from material selection and stain matching to engineered LVL and glulam installs.

Lehi deck & beam FAQs

Do I need a permit to build a deck in Lehi?

Usually, yes. Lehi City issues its own permits through the Lehi City Building Department (lehi-ut.gov). Any deck attached to the house, or with a walking surface more than 30 inches above grade, requires a permit and inspections under the 2021 IRC. Small freestanding ground-level decks can be exempt, but we confirm with the city before building — and we handle the permit paperwork for you.

How long does a deck build take in Lehi?

Most Lehi decks take 1–2 weeks of actual build time once the permit is issued and any HOA approval is in hand. Plan for extra lead time up front for design, engineering (if needed), Lehi City plan review, and HOA design review in communities like Traverse Mountain.

What decking material works best in Lehi?

Capped composite (Trex/TimberTech-style) is the strongest all-around choice for Lehi: it stands up to high-altitude UV at roughly 4,600 feet, freeze-thaw winters, and the wind-driven sun exposure on the Traverse Mountain bench without annual sealing. Cedar and redwood look beautiful and cost less up front, but plan on re-sealing every year or two. We price both options in every quote — see our deck cost guide for real numbers.
