Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.

Inspection lane

Call (970) 878-9452 and leave the address, permit number(s), preferred date/time, and inspection type; 24-hour notice is required and the County will schedule the same day if possible or the following workday. Plans must be onsite. Footings are inspected before concrete, and final inspection requires completed exterior/site work, State electrical approval, functioning mechanical/plumbing systems, and settlement of use tax before a Certificate of Occupancy.

Minor-work playbook

Understand what may be exempt—and what is not.

The County offers agricultural-exempt buildings for sole agricultural shelter use, with no permit fee or plans and only a setback inspection; electrical, plumbing, or heating requires separate permits. A Rural Building Exemption may be available for qualifying detached garages, shops, or similar buildings for a $250 fee, description/floor plan, and setback inspection; utilities, heat, and OWTS require separate permits. A Recreational Cabin Exemption is limited to owner recreation or periodic ranching, no more than 180 days of occupancy per calendar year, no commercial use, and no more than 800 square feet, with OWTS and other approvals still required. No broad cosmetic-work exemption list was published.

Field rule

A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.

Inspection pipeline

Keep the work visible at every release point.

  1. 1

    Request with lead time

    Call (970) 878-9452 and leave the address, permit number(s), preferred date/time, and inspection type; 24-hour notice is required and the County will schedule the same day if possible or the following workday.

Footings are inspected before concrete, and final inspection requires completed exterior/site work, State electrical approval, functioning mechanical/plumbing systems, and settlement of use tax before a Certificate of Occupancy.

  2. 2

    Preserve access

    Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.

  3. 3

    Close the record

    Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.

Contractor verification

Verify the builder before the contract is signed.

Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.

No verified lookup link

Planning reference

Keep the parcel rules beside the building plans.

A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Field sequencing matters

The inspector needs to see the work at the right moment.

Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.

When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.

Closeout file

Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
