What Are Utah Impact Fees?
Utah's Impact Fees Act (Utah Code § 11-36a) requires an impact fee facilities plan and written analysis before any local government or special district charges fees — commonly for water, sewer, storm drainage, roads, parks, and public safety across the Wasatch Front's growth corridor.
Utah County's boom cities (Lehi, Saratoga Springs, Eagle Mountain) and Washington County's St. George area carry the state's largest stacks, driven by water infrastructure. Utah figures on impactfees.org are model estimates — every jurisdiction must publish its fee analysis, so verify current schedules.
Utah figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
