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 Martin County.

Martin County Planning & Zoning administers the 2023 Martin County Land Use Zoning Ordinance and related county floodplain, shoreland, septic, feedlot, land-alteration, and development controls in unincorporated areas. Applications require compliance with applicable state laws, the Minnesota State Building Code, and state fire, electrical, plumbing, septic, and environmental requirements. The county sources reviewed do not publish a separate current 2026 county building-code edition.

Inspection lane

Submit the county building-permit PDF with owner, site, contractor, project, and scaled site-drawing information to Planning & Zoning. The Zoning Administrator conducts building and land-use compliance inspections. The permit is valid for one year after issuance; contact 507-238-3242 to coordinate inspections or confirm any project-specific scheduling requirements.

Minor-work playbook

Understand what may be exempt—and what is not.

The ordinance requires a zoning permit before erecting, altering, or moving a structure or exterior part, or installing an onsite sewage system or feedlot. Normal maintenance, necessary nonstructural repairs, and incidental alterations to a lawful nonconforming building or use are permitted when they do not extend or intensify the nonconformity. Construction sheds, agricultural buildings, and temporary structures located on a lot for 18 months or less are exempt from the ordinance's special moved-building photo requirements; municipal corporations and governmental agencies are exempt from ordinance fees.

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.

    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.

Which codes and exemptions should I review?

Martin County Planning & Zoning administers the 2023 Martin County Land Use Zoning Ordinance and related county floodplain, shoreland, septic, feedlot, land-alteration, and development controls in unincorporated areas. Applications require compliance with applicable state laws, the Minnesota State Building Code, and state fire, electrical, plumbing, septic, and environmental requirements.

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.
