Sandy deck & beam projects: what to know

Sandy is one of Salt Lake County’s biggest redeck markets. Much of the city was built out in the 1980s and 90s, which means thousands of original wood decks are now 30–40 years old — past the useful life of their decking and often their ledgers and posts too. A lot of our Sandy work is full replacement on an existing footprint: new framing, new footings where the old ones have heaved, and modern composite or cedar surfaces on top. If you’re budgeting, our Utah deck cost guide breaks down realistic per-square-foot numbers.

Location matters here more than most cities. Homes on the east bench toward Little Cottonwood Canyon sit noticeably higher than the valley floor, and design snow loads climb with elevation — along the Wasatch Front you’re planning around roughly 40+ psf ground snow load, with bench lots at the upper end. That drives beam sizing, joist spans, and footing depth (footings belong below the ~30-inch frost line). We design to the 2021 IRC that Utah enforces statewide, the same standards we build to across the valley and on custom deck projects in Utah County.

Sandy City permits

Deck permits in Sandy run through the Sandy City Community Development Department’s Building Division. In practice, you’ll need a permit for any deck attached to the house or standing more than 30 inches above grade — which covers most Sandy builds, especially on sloped bench lots. We prepare the drawings, submit the application, and schedule the inspections so you don’t have to.

Working inside the house instead? We also install structural and decorative interior wood beams throughout Sandy and the south Salt Lake Valley.

Sandy deck FAQs

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

Usually, yes. Sandy City requires a building permit for decks attached to the home or more than 30 inches above grade, per the 2021 IRC that Utah adopts statewide. A small freestanding deck sitting low to the ground may be exempt, but on Sandy’s sloped east-bench lots most decks cross the 30-inch threshold. Permits go through the Sandy City Community Development Department’s Building Division, and we handle the paperwork and inspections as part of every build.

How long does a deck build take in Sandy?

Once your permit is issued and any HOA approval is in hand, most Sandy decks take 1–2 weeks of on-site work: a day or two for demolition and footings, then framing, decking, and railing. Sandy City permit review and HOA architectural committees add lead time up front, so the best move is to start the process a few weeks before you want crews on site.

What decking material works best in Sandy?

At Sandy’s 4,500–5,000-foot elevation, high-altitude UV fades and dries out wood faster than most homeowners expect, and freeze-thaw cycles are hard on fasteners and finishes. Composite decking (Trex/TimberTech-style) is the low-maintenance winner here — it shrugs off UV and snow-shoveling. Cedar and redwood still look fantastic and cost less up front, but plan on re-sealing every couple of years, especially on south- and west-facing decks.
