Summit County permit types and how to file

There is no online application. A representative who can answer questions about the submittal brings the application form and plans to the counter, and the department does not accept emailed, mailed or couriered packages. No appointment is needed to submit or to see a plan reviewer.

  • Building Permit Application: used for building and demolition permits. A building permit covers the foundation, framing and carpentry, and the exterior and interior finishes.
  • Technical Permit Application: one form for mechanical, plumbing, fireplace, electrical and temporary power permits.
  • Hot Tub, Window, Park Home and Photovoltaic permit applications, each with its own form. A like-for-like, non-structural window replacement at a home needs no plans; commercial window replacement is plan reviewed.
  • Contractor Registration: every contractor must be registered with the department before pulling a permit, and only the employees named on the registration may sign for permits.
  • Special Inspector Application, where plan review decides a special inspector is needed.

A building permit expires 18 months after issue and can be extended once for up to 18 months on written request. Stand-alone technical, window and hot tub permits expire after 6 months, with one extension of up to 3 months.

Summit County permit fees

Fees come from the Summit County Building Department 2026 Fee Schedule, adopted as Exhibit B of the county’s 2024 code amendments. The building permit fee is read from a valuation table, and the valuation must include labor and materials for the plumbing, electrical, gas, mechanical and fireplace systems. The Building Official sets the final valuation.

Summit County building permit fee by valuation (2026 Fee Schedule)

The plan review fee is 65% of the building permit fee, is added to it, and is due when the plans are submitted. For a project valued at $400,000 the permit fee is $1,169.55 plus 300 × $6.73, which is $3,188.55; plan review adds $2,072.56, for $5,261.11 before trade permits and the impact fee.

Affordable housing impact fee: charged on new construction and additions. For a single-family home or duplex it is $0 up to 1,499 sq ft, $0.50 per sq ft from 1,500 to 2,499 sq ft, $1 from 2,500 to 3,499 sq ft, $1.50 from 3,500 to 4,999 sq ft and $2 at 5,000 sq ft or more. Commercial and industrial buildings pay $2 per sq ft. Copper Mountain and the Keystone PUD are exempt, and an owner can avoid the fee at permit issuance by recording the county’s Voluntary Housing Allowance Restrictive Covenant, which puts a transfer fee on later sales.

The counter takes cash, check, e-check ($1 fee) or credit card ($0.75 plus 2.25%). If a permit is cancelled before any work starts and before it expires, 80% of the permit fee may be refunded; the plan review fee is not refundable once the review is done.

Electrical, plumbing, mechanical and septic permits

Summit County runs its own trade inspection program, so electrical, plumbing, mechanical and fireplace permits are county technical permits, not state ones. Its inspectors check state electrician and plumber licences and apprentice ratios on site.

Electrical fees track the state electrical board’s schedule and can change from year to year. Residential technical permits need no plan review; commercial mechanical, plumbing and electrical work always does.

Solar: a residential roof-mounted system under 15 kW can be issued over the counter with a complete submittal. Larger, ground-mounted and commercial systems are plan reviewed. The adopted 2026 schedule prices solar on the electrical valuation table with a cap of $400 for residential and $1,000 for commercial systems, although the department’s fee web page still lists the earlier flat charges of $175 plus $325 and $350 plus $650. The installer must be a NABCEP certified PV installer.

Septic: the Summit County Environmental Health Department issues onsite wastewater treatment system permits and inspects every new system and repair. The work has to be done by a licensed OWTS contractor, and Environmental Health also reviews wells and water rights during building plan review.

Fire sprinklers: a new home larger than 4,500 sq ft, counting attached garages, must be sprinklered, and the fire district reviews, permits and inspects the system.

What to bring: the county submittal checklist

The Permit Submittal Completeness Checklist (July 2026) is written mainly for new houses and additions. Bring one set of stamped plans with the application form.

At the counter you receive a sign-off card listing the outside referral agencies for your subdivision, usually the water, sewer and fire districts. Every sign-off has to come back to the office before the permit is issued. Fire district approval is required on all commercial and multi-family permits.

Planning checks use, setbacks, lighting and height; Engineering checks site stability, wetlands, grading, drainage, driveways and erosion control; Environmental Health checks septic design; Housing reviews workforce housing projects. Building Inspection comments are typically sent within 2 weeks of submittal, and overall timing depends on the season and how complete the plans are.

How to apply: 7 steps at the Summit County counter

1. Find the right office

Unincorporated addresses and sites in Dillon, Keystone and Montezuma go to the county. In those three towns, get the Town’s development permit or sign-off first.

2. Look up your subdivision in the Matrix

The Building Inspection Department Matrix gives the roof snow load, whether a soils report is expected, and which water, sewer and fire districts must sign.

3. Register the contractor

File the Contractor Registration form with a $1,000,000 general liability certificate naming the department, or pass the homeowner builder test.

4. Submit in person

Bring the application, one stamped plan set and the checklist items to the County Commons before 4:30 p.m. and pay the plan review fee.

5. Collect referral sign-offs

Take the sign-off card to each listed district while the county departments review the plans.

6. Pick up the permit

When every department has approved, a permit technician notifies you to collect the permit and pay the balance, including any impact fee.

7. Schedule inspections in eTRAKiT

Link the permit number to your account and request each inspection by 5 p.m. the business day before.

Summit County inspections

All inspections are requested online in eTRAKiT, up to 3 business days ahead, and a next-day request must be in by 5 p.m. on the business day before. Inspectors visit on the day scheduled, and each inspector’s route slip is posted online every morning. A morning or afternoon slot can be requested for concrete inspections only.

  • Technical inspections must be requested under the technical permit, not the building permit.
  • The approved plans and every approved change must be on site. Plan changes are submitted in person with the original red-lined set, and inspectors do not review changes in the field.
  • Do not type gate or door codes into the request notes, which are public; phone them to the office.
  • After a failed inspection, correct the work and book a re-inspection before moving to the next phase. If a $65 re-inspection fee is assessed, eTRAKiT blocks new requests until it is paid.
  • All final inspections have to be scheduled for the same day.
  • To cancel, use eTRAKiT before 5 p.m. the business day before, or leave a message on 970-668-3170 after that.

A home can be occupied only after the Certificate of Occupancy is issued, which needs every building and technical permit complete and all referral agency sign-offs in hand. A temporary certificate is possible with the Building Official’s approval.

Local Summit County rules that change the design

2024 codes: plans submitted on or after July 1, 2026 must meet the 2024 International Codes with county amendments. The Summit County Sustainable Code is no longer an energy option for single-family homes, which now follow the 2024 IECC with a simplified prescriptive path.

Wildfire hardening: permits applied for on or after May 4, 2026 fall under the Colorado Wildfire Resiliency Code with county amendments. The county treats every part of Summit County, town centers included, as moderate to high fire intensity requiring Class 2 structure hardening: Class A roofing, noncombustible gutters, vent mesh of 1/8 in. or finer, ignition-resistant or noncombustible siding and deck surfaces, and noncombustible or ignition-resistant fencing within 8 ft of the building.

Snow, frost and wind: the frost line is set at 40 in. below grade, and deck piers carrying no roof may be 24 in. deep. Roof snow loads are assigned by subdivision in the Matrix, from 70 to 100 psf, with no reduction for duration. The Matrix lists a 115 mph design wind speed.

Outdoor energy use: under the Renewable Energy Mitigation Program, exterior hot tubs, pools and snowmelt systems must have 50% of their energy use offset by on-site renewable energy, and fuel-fired heaters are not allowed for them. One hot tub of up to 64 sq ft per single-family home and the first 100 sq ft of residential snowmelt are exempt.

Homeowner builders: an owner building or altering their own principal residence may pull building and technical permits after passing the county’s free, open-book tests with 80% or better on the first attempt. Trusts and LLCs do not qualify, short-term rental properties are excluded, and a new home project is allowed no sooner than 2 years after the last Certificate of Occupancy obtained as a homeowner builder.

Hot tubs on wells: filling an outdoor hot tub from a well may need water augmentation, and proving adequate water rights is the owner’s responsibility.

Colorado building code

Colorado has no statewide building code for private buildings: each city and county decides whether a code applies and which edition, while the state sets electrical and plumbing rules, a minimum energy code on any update, and a wildfire code for the mapped wildland-urban interface.
