A new house can take up to 14 business days to review. Park City, Coalville, Francis, Henefer, Kamas and Oakley each permit construction inside their own limits.

The County requires a building permit to build, enlarge, alter, repair, move, improve, remove, convert or demolish any building or structure, and for solar PV systems. Its checklists cover accessory structures, additions, basement finishes, decks, EV chargers, exterior cladding, generators, geothermal and radiant heat, manufactured and modular homes, pools and hot tubs, retaining walls, roofing, signs, temporary structures, utility upgrades and windows, as well as new homes and commercial buildings.

How to apply in EPROCESS 360
Register for an EPROCESS 360 account, choose Building Permit Application (or Right of Way Permit Application) under Create New, fill in every section, pick the scope of work and upload the documents that scope requires as unrestricted PDFs, each labeled with its document type. The parcel must already have an assigned address; GIS Mapping assigns one if it does not. Applications that arrive after 5:00 p.m. count as submitted the next business day, and incomplete ones are rejected. The County sends email updates as each department comments or approves.

Summit County permit fees
Fees are calculated in EPROCESS 360 and shown on the permit’s Fees tab.

| Item | Detail |
|---|---|
| Transportation impact fee (Ordinance 958) | Applies across unincorporated Summit County; Exhibit C, the fee schedule Ordinance 958 imposes, lists $3,427.03 per single-family home and $1,938.52 per low-rise multifamily unit, paid at development approval; the County decides during permit review whether a project owes it |

Trade work is part of the County building permit and is inspected by the County’s building inspectors. Gas line and power-to-panel inspections happen only after the 4-way inspection: the gas line diagram and the County Gas Clearance Form must be uploaded, and the line must be under test pressure. Power to panel needs at least two 20-amp GFCI-protected circuits. Temporary power uses temporary service equipment, not the permanent panel, except for some free-standing meter sets approved case by case.
Septic and wells: homes on septic need Final Wastewater Approval from the Summit County Health Department before occupancy, and homes on a well upload the well log with the final documents. Homes on a public system need an approval letter from the water provider and, for sewer, from the Snyderville Basin Water Reclamation District where it serves.
Summit County submittal checklists and design values
Every project type has its own checklist (updated April 21, 2026), and everything on it must be uploaded at submittal. The County’s design criteria, effective July 1, 2026, use the Utah ground snow load map for snow, 115 mph wind, Seismic Design Category D or D1, a 36-inch frost line, a −7°F winter design temperature and required ice barrier underlayment; flood hazards follow the FEMA flood map.
New single-family homes may take up to 14 business days for review and new commercial projects up to 21 business days. Comments from each department appear on the permit’s Submittals tab, and corrected plans are uploaded there.

Inspections are scheduled through EPROCESS 360, and a printed copy of the County-stamped plan must be on site. County Engineering inspects the rough grade before the footing inspection, and the geotechnical report must be on site at the footing. Required certificates of elevation or survey must be approved before the shear or framing inspection. Windows, fireplaces and furnaces must be installed before the 4-way, and spray foam must be inspected before other insulation covers it.
The local fire district inspects first, usually at the 4-way, final and solar stages, and its inspections are booked directly with the district. Special inspections listed on the plans are done by independent third-party inspectors, whose reports are uploaded to the portal. Remote areas along the Mirror Lake Highway, such as Manor Lands, Wilderness Acres and Christmas Meadows, are not given fixed inspection times because of travel distance.
A passed final inspection is not a Certificate of Occupancy: the C of O is issued only after Building, Engineering, the fire district, the water provider, the sewer district or Health Department and, for projects with a site plan, Planning have all signed off.
Local Summit County details that matter
Many service providers: the County’s permit review agency list names three fire districts (Park City, North Summit and South Summit), the Snyderville Basin Recreation District, the Snyderville Basin Water Reclamation District and several water companies, including Summit Water Distribution, Mountain Regional Water and Gorgoza Mutual Water. Which ones apply depends on where the lot is.
Steep lots: a geotechnical report is required where the slope is 15% or greater, and it must be on site at the footing inspection.
Construction mitigation: the County may require a Construction Mitigation Plan and a Construction Acknowledgement, and bonds posted for a project are released with the Bond Release Request Form.
