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.

Regulatory framework

The code baseline for Dunn County.

Dunn County Chapter 13 Comprehensive Zoning Ordinance, Chapter 14 Shoreland Protection, Chapter 15 Floodplain Zoning, Chapter 16 Land Division/Condominium/Surveying, and county sanitary/POWTS regulations. Chapter 13 applies in participating unincorporated towns; county shoreland, floodplain, land-division, and sanitary rules apply across all towns. State Uniform Dwelling Code building permits and inspections are separately administered by each town's designated inspector.

Inspection lane

Stake the footprint and notify the Planning & Zoning Division at 715-231-6520 when it is ready; county staff performs an on-site zoning inspection before permit issuance. One site inspection is included in normal processing (up to two for shoreland applications), with additional-inspection fees if needed. County staff also inspects new or replacement sanitary systems; schedule town UDC construction inspections separately with the applicable township building inspector.

Minor-work playbook

Understand what may be exempt—and what is not.

Chapter 13 does not require a county zoning permit for a readily removable, non-habitable accessory or farm structure under 100 square feet that meets setbacks; interior remodeling without a prohibited change of use; exterior remodeling that adds no floor area; setback-compliant above-ground/on-grade pools; compliant fences; ground-level platforms, terraces, walks, driveways, parking areas and patios; or retaining walls supporting ground at or below its natural level. Other county, town, UDC, shoreland, floodplain, or sanitary approvals may still apply.

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

    Stake the footprint and notify the Planning & Zoning Division at 715-231-6520 when it is ready; county staff performs an on-site zoning inspection before permit issuance. One site inspection is included in normal processing (up to two for shoreland applications), with additional-inspection fees if needed. County staff also inspects new or replacement sanitary systems; schedule town UDC construction inspections separately with the applicable township building inspector.

  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.

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.

How long might review take?

Chapter 13 requires a written grant or denial within 30 days after a complete application. The expedited option is processed within 10 working days after receipt of a complete application.

How are inspections scheduled?

Stake the footprint and notify the Planning & Zoning Division at 715-231-6520 when it is ready; county staff performs an on-site zoning inspection before permit issuance. One site inspection is included in normal processing (up to two for shoreland applications), with additional-inspection fees if needed. County staff also inspects new or replacement sanitary systems; schedule town UDC construction inspections separately with the applicable township building inspector.

Which codes and exemptions should I review?

Dunn County Chapter 13 Comprehensive Zoning Ordinance, Chapter 14 Shoreland Protection, Chapter 15 Floodplain Zoning, Chapter 16 Land Division/Condominium/Surveying, and county sanitary/POWTS regulations. Chapter 13 applies in participating unincorporated towns; county shoreland, floodplain, land-division, and sanitary rules apply across all towns. State Uniform Dwelling Code building permits and inspections are separately administered by each town's designated inspector. Chapter 13 does not require a county zoning permit for a readily removable, non-habitable accessory or farm structure under 100 square feet that meets setbacks; interior remodeling without a prohibited change of use; exterior remodeling that adds no floor area; setback-compliant above-ground/on-grade pools; compliant fences; ground-level platforms, terraces, walks, driveways, parking areas and patios; or retaining walls supporting ground at or below its natural level. Other county, town, UDC, shoreland, floodplain, or sanitary approvals may still apply.

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.
