Wapello County, Iowa Building Permit Guide

Outside city limits, Wapello County Planning and Zoning (536 Mill Street, Ottumwa; 641-684-5425) reviews plans, issues building, electrical, plumbing and HVAC permits, and inspects new houses, additions and commercial and industrial buildings. Its Chapter 43 construction code, in force since January 1, 2026, adopts the 2021 International Building, Residential and Existing Building codes with the state trade codes. Applications, payment and contractor registration go through the county’s GeoPermits site, and the office sees visitors by appointment.

What requires a permit in unincorporated Wapello County?

Under Chapter 43, anyone who builds, enlarges, alters, repairs, moves or changes the occupancy of a building, or installs or changes electrical, gas, mechanical or plumbing systems, must first get a permit from Planning and Zoning. Building, electrical, HVAC and plumbing work each take their own permit, and a zoning review applies to the parcel’s land use district.

Buildings primarily adapted for and used in agriculture are outside Chapter 43, and the county may ask the owner to show that a building qualifies. The farm exemption ends at the floodplain: agricultural building, filling or excavation in a flood hazard area still has to meet federal, state and county flood rules. Emergency repairs may start first, but the permit application is due the next working day.

What the county decides and what the state holds

The Board of Supervisors adopted the current Chapter 43 on December 2, 2025. It adopts the 2021 International Building, Residential, Existing Building, Swimming Pool and Spa and Property Maintenance codes, with local amendments: design loads of 30 psf ground snow and 115 mph wind, and a thickened-edge floating slab allowed for detached garages and sheds up to 1,000 square feet and 18 feet tall that stand more than 10 feet from a house. It adopts the state electrical, mechanical, plumbing, fire, fuel gas and energy codes as they are updated, and it states plainly that the county does not adopt the State Building Code under Iowa Code 103A.10.

Wapello County building department: who handles permitting

Planning and Zoning, led by Administrator Miranda Bailey, approves plans, issues permits, inspects and makes zoning recommendations for the unincorporated area, with a zoning assistant who is also a building inspector and a second building inspector. The same Mill Street office houses Environmental Health and the County Engineer’s Secondary Roads department.

Cities in Wapello County

Chapter 43 does not apply inside a city unless the county signs a 28E agreement to serve it, so each city handles its own permits. The county’s 2025–2026 minutes show 28E agreements with Agency, Blakesburg, Eldon and Kirkville for sheriff patrols, not for building inspection.

Wapello County permit types

GeoPermits handles building, septic, utility and oversize permits, contractor registration, document uploads and online payment, and keeps a record of every application on the applicant’s account. Variances and rezonings use paper applications from the Planning and Zoning page.

Residential permits

An application must describe the work, identify the parcel, state the intended use and include construction documents, manufacturers’ information, any flood hazard documents and a site or plot plan. A house needs a building permit plus separate electrical, HVAC and plumbing permits, a septic permit where there is no sewer and, before final, a posted E-911 address. Owners doing work on their own primary residence are exempt from the trade license requirement if they sign an affidavit that they own and live in the home and intend to stay at least a year.

Commercial permits

Commercial and industrial buildings follow the 2021 IBC and the state fire, energy and accessibility rules adopted in Chapter 43, including the ADA Standards for Accessible Design. When the county’s building official cannot complete a plan review, the applicant pays the outside firm or jurisdiction the official authorizes, on top of the county permit fee. Factory-built structures follow the state rules on factory-built and manufactured housing anchorage.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

Existing buildings and planning changes

Chapter 43 also brings the 2021 International Property Maintenance Code to the rural county, with Planning and Zoning as the enforcement agency. Its local procedure lets the code official placard condemned or derelict structures, nuisance properties and parcels that break the zoning rules, and spells out how notice of an inspection is given and when a search warrant may be sought. Repairs ordered under the code still need permits. On the planning side, the supervisors approved a 2025–2045 comprehensive plan on June 2, 2026, and a draft renewable energy ordinance, last updated April 16, 2026, is posted for wind and solar projects.

What comes before the building permit

• Zoning. Chapter 40 divides the county into seven districts, from A-1 Agricultural to I-2 Heavy Industrial with an airport overlay; rezonings go to the Planning & Zoning Commission and the supervisors, and variances ($300 application) to the Board of Adjustment.
• Septic and well. Environmental Health evaluates the site, cores and classifies the soil and issues the septic permit.
• Floodplain. Substantially improved structures in mapped flood areas must meet Chapter 36 and Iowa DNR standards.
• Entrance. A County Engineer permit before any new or changed driveway onto a county road.

Wapello County permit costs and fees

Chapter 43 leaves every permit fee to a Board of Supervisors resolution. The current schedule is Resolution 3-2026, “Adopting New Fee Schedule in Unincorporated Areas of Wapello County”, approved on March 10, 2026; the fee amounts are not posted: the table is not part of the posted minutes and the county pages read for this guide do not list it, so no figures are given here and you should ask Planning and Zoning for a quote before you budget; fees are paid online through GeoPermits when you apply.

The re-inspection charge is meant to stop calls for inspections before work is ready; it can also apply when the inspection card is not posted, the approved plans are not on site, or the work departs from the plans. At an April 2026 supervisors’ meeting, county staff reported about twenty building permits so far that year, against six in all of the year before, many for remodels and large new structures.

Trade permits and who may pull them

• Electrical: issued by Planning and Zoning in the unincorporated county, so rural Wapello County work is permitted and inspected locally rather than through the state.
• Plumbing and HVAC: county permits under the state plumbing and mechanical codes.
• Licenses: Chapter 43 requires a state master Class A or Class B license for electrical, plumbing and HVAC installations, alterations and major repairs; the master may take out permits only for their own firm or employer, may not lend the license or sub out the work to an unlicensed party, and must be available to stand inspections.
• Contractor registration: contractors register with the county through GeoPermits, and septic installers have their own county registration.
• Homeowners: may do their own trade work on their primary residence after filing the owner-occupancy affidavit.

How to apply for a Wapello County permit

Review, corrections and what causes delay

The building official reviews applications in a timely manner but contacts the applicant with questions, and changes to the plans extend the review. Common holdups are missing construction documents or flood hazard information, a septic site that needs soil work, an entrance that fails the sight-distance rule, and zoning cases that need a variance or rezoning hearing. Decisions of the building official can be appealed to the five-member Construction Board of Appeals within 14 days.

Inspections in Wapello County

The permit holder tells the building official when work is ready, and nothing may be covered until it passes. Chapter 43 lists the usual sequence: rebar in footings or post holes before concrete or posts; rebar in foundation walls; under-slab mechanical, plumbing and electrical with tests; slab rebar; framing with hurricane ties; rough plumbing with tests; rough electrical; rough mechanical with tests; and the final inspection for the certificate of occupancy, by which time the E-911 address must be posted. If work is covered before inspection, the building official may require the contractor’s photos, a notarized statement that the work meets code, or exposure of the work at the contractor’s cost.

For driveways, call the County Engineer when the entrance is finished; the inspector accepts or rejects it, and corrections must be made before it is used. Entrances need 400 feet of sight distance each way on gravel and 600 feet on pavement, and may not sit within 100 feet of a bridge or guardrail. Septic systems get a final inspection by Environmental Health, and septic time-of-transfer inspections at sale are valid for two years.

Iowa building code

Wapello County enforces its own Chapter 43 construction code in the unincorporated area. FEMA’s Community Status Book lists the county as participating in the National Flood Insurance Program, with flood maps effective January 29, 2021; building officials and the appeals board may not grant any modification of the flood-prone-area requirements in Chapter 36 and the IRC.

Iowa lets most cities and counties adopt the state building code, another code or none (a city of more than 15,000 must enforce at least the state code), but the energy, accessibility, fire, plumbing, mechanical and electrical rules apply statewide. Iowa rules
