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 Montgomery County.

No separate 2026 technical IBC/IRC edition was identified in the county's published materials. Montgomery County enforces the Revised Zoning Ordinance for unincorporated Montgomery County, effective July 14, 2021, including zoning permits/certificates, permitted uses, lot and setback standards, site plans, land-disturbance thresholds, subdivision, and applicable State of Iowa and County Sanitarian/DNR approvals. The published county program is a zoning-certification program rather than a separately identified county building-code inspection program.

Inspection lane

Contact Zoning Administrator Barry Byers at 712-623-5197. File a written zoning application with duplicate, scaled plans showing the lot, proposed structure location, size, height, use, and related information; include State approvals such as stormwater or confinement permits and County Sanitarian well/septic approvals when applicable. The lot and building location must be staked before construction. No county inspection-scheduling portal or separate county technical inspection procedure was published; coordinate any required technical inspections with the applicable state or other authority.

Minor-work playbook

Understand what may be exempt—and what is not.

Agricultural uses do not require a zoning permit/certificate under the county ordinance. For non-farm development, no permit is required for routine maintenance, repair, or remodeling with no change of use or additional lot coverage; essential services; or ordinary lot/yard improvements such as children's playhouses, drives, fences, concrete patios, decks, play equipment, retaining walls, sidewalks, and landscaping, unless the improvement is on, over, or within 10 feet of a septic system or utility easement. The ordinance identifies new accessory buildings of less than 120 square feet, signs under 20 square feet, and land disturbance under 1 acre as outside the listed non-farm permit triggers. Agricultural exemptions do not eliminate separate septic, DNR, electrical, or other applicable approvals.

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

    Contact Zoning Administrator Barry Byers at 712-623-5197. File a written zoning application with duplicate, scaled plans showing the lot, proposed structure location, size, height, use, and related information; include State approvals such as stormwater or confinement permits and County Sanitarian well/septic approvals when applicable. The lot and building location must be staked before construction. No county inspection-scheduling portal or separate county technical inspection procedure was published; coordinate any required technical inspections with the applicable state or other authority.

  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.

Project questions

Frequently asked questions for Montgomery County

Who handles permitting for this jurisdiction?

Montgomery County Zoning Division is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.

How should I begin an application?

No verified online portal was located in the reviewed public materials. Contact 712-623-5197 and request the current application route before preparing a final submittal.

How long might review take?

N/A. No standard review timeline was published. A zoning permit becomes void after six months if construction, alteration, or change of use has not commenced; proposed construction or alteration must be completed within 18 months.

How are inspections scheduled?

Contact Zoning Administrator Barry Byers at 712-623-5197. File a written zoning application with duplicate, scaled plans showing the lot, proposed structure location, size, height, use, and related information; include State approvals such as stormwater or confinement permits and County Sanitarian well/septic approvals when applicable. The lot and building location must be staked before construction. No county inspection-scheduling portal or separate county technical inspection procedure was published; coordinate any required technical inspections with the applicable state or other authority.

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.
