Residential Building Permit (Single Family Dwelling, New Construction) in Unincorporated Wasatch County, Utah

Required for new single-family dwelling construction in unincorporated Wasatch County. The 2021 IRC governs architectural design (unchanged) and the 2024 IBC governs structural design per Utah Code §15A-2-103, though the county's own Single Family Dwelling plan-submission checklist still directs applicants to the 2021 IBC for structural design (live-checked 2026-07-16) — confirm with the Building Department which edition current plan review actually applies. Fees are assessed on a per-square-foot basis for the Building Department portion, per the county's Building Permit FAQ.

Tips

  • The Plan Review Fee is invoiced by email AFTER you submit for review — it is not collected at the time of initial application, and only online payment (check or card) is accepted; no in-office payments.
  • As of April 8, 2025, Gas Schematics, Manual J & D Heat Loss Calculations, Fire Sprinkler Plans, and Truss Packages are no longer required for a COMPLETE submittal, but each is still required to be present onsite/uploaded before its corresponding inspection (Gas Line Test & Schematic, 4-Way, Rough Fire Sprinkler, and roof framing inspection, respectively).
  • If your parcel is over 1 acre and total disturbed area (structure footprint + driveways/parking) reaches 1 acre or more, you need a separate Engineering Permit from the county's Engineering Department in addition to your building permit.
  • The $1.25/sq ft Building Department fee figure published in the county's own FAQ is explicitly dated to June 2016 and described as an average — confirm current per-project costs directly with the Building Department at (435) 657-3200.
  • The County Impact Fee for a new single-family residence drops from $3,085 to just $278 if the property is within Wallsburg Town — a large jurisdictional carve-out worth confirming if your parcel is near that boundary.
  • EV charger (EVSE) installation is treated as standard electrical work under this same Building Permit process — the county's official Building Permit FAQ (wasatchcounty.gov/215/Frequently-Asked-Questions, live-checked 2026-07-19) itemizes 'Other Fees' (temp power, Solid Waste SSD garbage fee, Fire/Water/Sewer/Power district fees) with no separate electrical trade-permit line and no EV-charger or electric-vehicle-charging line item anywhere on the page. Confirm project-specific requirements with the Building Department at (435) 657-3200.
