Residential Building Permit in Unincorporated Summit County, Utah

Tips

• The County's own Single Family Dwelling Checklist (current as of 4/2026) states: 'Review timeframes are ESTIMATED to be 9-14 business days.' The EPROCESS360 FAQ separately states new single-family dwellings 'may take up to 14 business days for review' and new commercial projects 'may take up to 21 business days.'
• Summit County's Building Permit Fee IS published — Ordinance 834-P (County-Wide Fee Schedule), item 2, sets it at a flat 0.0075 (3/4 of 1%) of construction valuation, $100 minimum, applying to both residential and commercial permits. Construction valuation is computed from the ICC Building Valuation Data (BVD) table (published by the County, February 2026 edition). A $200 Plan Review Deposit (credited toward the 65%-of-permit-fee Plan Review Fee) is due for new structures. The final dollar total still isn't visible until EPROCESS360 completes plan review and applies the exact valuation, but the rate/formula itself is no longer undisclosed — contact the Building Department at (435) 336-3124 or buildingquestions@summitcountyutah.gov for a project-specific total.
• All submissions, reviews, and permit issuance go through the EPROCESS360 online portal (summit.co.ut.eprocess360.com) — the County does not accept paper plans or perform over-the-counter reviews.
• Starting January 1, 2025, the County changed its permit 'Scope of Work' classification titles — applicants must select the correct new title (e.g., 'New Single Family Detached (IRC)', 'Addition (Living Space)', 'Alteration (Interior)') or the application will be rejected for insufficient information.
• Permits are valid for 180 days from the last activity; a Permit Extension Request may be submitted once.
• Snyderville Basin properties (surrounding Park City) fall under the separate Snyderville Basin Development Code (Title 10, Chapter 8) with its own Planning Commission and General Plan — confirm which of the County's two planning districts (Snyderville Basin vs. East Side) your parcel is in, since planning/zoning prerequisites can differ even though building permit review is handled by the same County Building Division.
• A written statement confirming water availability (existing system hookup letter, or well/water-rights evidence) is required before a dwelling building permit can be issued.
• Certificate of Occupancy requires final Building and Engineering inspection approval, a Final Fire Inspection report, and (depending on water/sewer source) either a well log, a water-system final approval letter, a sewer-system final approval letter from Snyderville Basin Water Reclamation District, or Final Wastewater Approval from the Summit County Health Department for septic systems.
• Rooftop and ground-mounted solar PV installations go through this same Residential Building Permit process in EPROCESS360, with no distinct solar fee line published — neither the County-Wide Fee Schedule (Ordinance 834-P) nor the ICC Building Valuation Data table contains the word 'solar'. Historically, Summit County (with Park City) was one of Utah's first two jurisdictions to adopt the 'Solar ABCs' expedited/streamlined model solar permitting process, per Utah Clean Energy's Solar Permitting Toolbox, but the original standalone checklist document (DocumentCenter View 272) link no longer resolves. Confirm current solar-specific submittal requirements with the Building Department at (435) 336-3124.
• EV charger (EVSE) installation is treated as standard electrical work under this same Residential Building Permit / electrical permit process, not a distinct permit type — see the dedicated ev-charger-permit entry. In the full County-Wide Fee Schedule (Ordinance 834-P, published as a scanned document), the Building Department Fee Schedule's 'Alternative Energy Permits' category is explicitly limited to solar, hot water, photovoltaic, geo-thermal, and wind generated power — no EV/electric-vehicle line item exists anywhere in the schedule, so EV charger installation is billed as ordinary electrical work under the general Building Permit Fee (0.0075 of construction valuation, $100 minimum).
