New Deck Construction on the Wasatch Front

A new deck starts as a picture of summer evenings and ends as a framed structure carrying people above your yard. Both things are true, and the second one is what makes the first one safe. Long before anyone talks about board color, a builder worth hiring is thinking about where the footings land, how the frame ties into your house, and what your finished height above grade means for guards and stairs.

We connect homeowners in Salt Lake, Utah, Davis, and Weber counties with contractors who work in that order. You describe the yard, the door you want to walk out of, and how you picture using the space through a Utah summer. They handle layout on site, drawings, permitting, footing depth, the ledger detail at the house, and the inspections your city expects along the way.

What goes into a deck before it looks like a deck

  • Layout against your door height — Where the deck meets your threshold sets step-downs, how water drains away from the house, and how much yard you give up. That gets settled standing in the yard, not on paper.
  • Footings that reach below frost — Holes go deep enough that freezing soil cannot lift them, sized for the load each post carries. Access for equipment and what the digging finds both shape how this part goes.
  • A ledger that is flashed, not just fastened — The board tying the deck to your house gets structural fasteners and flashing that pushes water out over the siding, so nothing gets behind it into the rim joist.
  • Joists, beams, and honest spans — Joist size and spacing follow the distance being spanned and the surface going on top. Get this right and the deck feels solid underfoot for its whole life.
  • Guards matched to your height above grade — How high the deck sits changes what is required at the edges. Guard posts get blocked and fastened into the frame rather than screwed to the rim as an afterthought.
  • Stairs and landings — Most of the fussy detail on a deck lives in the stairs. Consistent risers, solid stringers, a landing that drains, and a handrail your hand can actually close around.

How a new build moves from yard to final inspection

  1. Walk the yard with you — Doors, sun angles, slope, sprinklers, and where you already sit outside. A deck that ignores how you use the yard is just a platform, and you will feel that later.
  2. Drawings and permit — Framing plan, footing sizes, guard and stair details, submitted to your city. Requirements differ by jurisdiction along the Wasatch Front, so this step is done locally, not from a template.
  3. Footings, then frame — Holes dug below frost depth and inspected where required, then posts, beams, joists, and the ledger detail at the house. The deck is essentially finished at this stage, structurally speaking.
  4. Surface, guards, and stairs — Decking goes down, guards and stairs get built to your height above grade, and the city inspects. Then you get the part you were picturing the whole time.

What it costs

Deck pricing follows structure more than style. Square footage matters, but so does height above grade, because a deck that sits well above the ground needs taller posts, more bracing, and guards on every edge. Footing depth and how easily equipment can reach the backyard change the excavation. Decking material sets the surface, and railing type can swing a budget as much as the boards do. Stairs and landings add framing, footings, and detail work wherever they land. And if a cover is part of the plan, it adds structural load, which reaches all the way back down to the footings.

Questions people ask

How far below grade do the footings have to go?

Below the frost line, and that depth is set by your jurisdiction rather than by preference. Utah winters push frost down far enough that a shallow footing will heave and keep heaving, which shows up later as racked posts and separating stairs. Your contractor will pull the requirement for your city, and you can confirm it with the building department.

Can a new deck attach to any house?

Not automatically. The ledger has to land on framing that can carry it, and the wall assembly has to allow flashing that keeps water out of the rim joist. Some houses, especially certain veneers and cantilevered areas, are better served by a freestanding deck with its own posts and footings. That decision gets made on site.

How does deck height change the build?

Considerably. Height above grade affects guard requirements at the edges, whether the space underneath is worth keeping usable, how stairs are laid out, and how much lateral bracing the posts need. A low deck a step off the lawn and a second-story deck off the kitchen are different structures even if the floor area matches.

What can I do to make the space underneath usable?

Plan drainage before the deck is framed. On an elevated deck, water passing between the boards decides whether the area below is a dry patio or a place things go to get wet. Grading, a drainage system under the joists, and where downspouts discharge all matter, and retrofitting them later is harder than building them in.

Other services

Deck Repair & Rebuild

When boards rot, posts shift, or the frame bounces underfoot, the fix depends on what is underneath. A contractor opens up the ledger and looks at the footings first, then tells you plainly whether you are repairing a sound structure or replacing a tired one.

Covered Decks & Pergolas

Shade changes the math. A roof or pergola adds wind and snow loading to framing and footings that were never sized for it, so a cover gets designed as a load path running from the top down through posts into ground that can hold them.

Railings, Stairs & Safety

Guards and stairs carry more code detail than the rest of the deck combined, and older ones often would not pass today. Post attachment, infill spacing, tread and riser consistency, landings, and a handrail your hand can actually close around.

Composite & Resurfacing

New decking over old framing only works if the framing earned it. Joist spacing, fastener type, and drainage get checked before the first board goes down, along with straight talk about heat, cleaning, and what each surface asks of you later.
