Structural engineering for Kaysville custom homes and additions.

Kaysville is the high-end residential pocket of Davis County. Lots of custom builds, premium decks, and the kinds of projects where the engineering needs to be right.

Kaysville is the high-end residential pocket of Davis County. Larger lots, taller trees, more custom homes, more architects, and a higher proportion of "this isn't going to fit a prescriptive table" engineering. It's our favorite kind of work, frankly.

What we do most in Kaysville

  • Custom home structural design. Vaulted ceilings, large window walls, cantilevered decks, basement walkouts on sloped lots, and the lateral systems to make all of it work.
  • Retaining walls. Sloped lots in Kays Creek, Crestwood, and Hidden Hollow generate a lot of tall retaining wall work. Tiered systems are common, which usually require engineering even if individual tiers would otherwise be under 4 feet.
  • Premium decks and outdoor living. Outdoor kitchens, hot tubs, large covered patios, and elevated decks. Snow loads on the bench are real and the engineering has to reflect that.
  • Additions on established homes. A lot of the 1990s–2000s Kaysville custom homes are getting their first significant remodel — new primary suites, expanded kitchens, second-story bedrooms.
  • ADU plans. Both internal and detached. Kaysville has the lot sizes to support detached ADUs in many neighborhoods.

Kaysville-specific things to know

  • Bench snow loads. Lots above ~4,800 feet start to see meaningfully higher snow loads. This affects everything from rafter spans on a custom home to deck beam sizing on a hot tub deck.
  • Slope and drainage. Many Kaysville lots have real grade. That means retaining wall design, often, and it means surface and subsurface drainage is part of the job — not an afterthought.
  • Custom architectural conditions. The big residential shops in Salt Lake are often set up for tract home volume. Custom homes with one-off conditions take more attention than they have time for. That's where we come in.

A recent Kaysville project

A new custom home on a sloped Kays Creek lot needed a 9-foot tiered retaining wall to create the walk-out basement and a flat back yard above. We designed both walls (a cantilever upper and a gravity-base lower) accounting for the surcharge of the upper terrace, the drainage system between them, and the soil conditions. The contractor built it in one summer and the homeowner has had zero issues two winters in.

FAQ

Questions from Kaysville homeowners

What's different about engineering in Kaysville vs. other Davis County cities?

Kaysville has more custom homes per capita than any other Davis County city. That means more unique architectural conditions — vaulted spans, large openings, cantilevers, expansive glass, hillside foundations, and tall retaining walls — that don't fit prescriptive code tables. More of what we do in Kaysville is real engineering, not just letters.

Are the snow loads higher in Kaysville?

On the east bench, yes. Lots up against the foothills in Kays Creek, Crestwood, and Hidden Hollow can sit at 4,800–5,300 feet, putting design ground snow loads at 45–55 psf — meaningfully higher than valley homes. We always design to the actual elevation of the specific lot.

Are detached ADUs allowed in Kaysville?

Internal ADUs are permitted in single-family residential zones per HB 82. Detached ADUs face additional setback and lot-coverage requirements — generally allowed but with stricter rules than internal. Worth a call to Kaysville City Building before you commit to a layout.
