Shelby County, Iowa Building Permit Guide

In unincorporated Shelby County, anyone building a structure worth more than $5,000, farm or not, must file a $50 Application for Construction Approval with Shelby County Planning & Zoning at the courthouse, 612 Court St., Harlan (712-755-5718, ext. 5). The county works under Zoning Ordinance 2006-6 rather than a building code; Environmental Health on Industrial Parkway permits septic systems and wells, and the County Engineer issues no-cost entrance permits.

What requires a permit in rural Shelby County?

Section 1.1 of Zoning Ordinance 2006-6 says no land or building may be used, and no building or structure located, built, extended, converted or structurally altered, except in full compliance with the ordinance. The filing trigger is set in section 22.311: anyone proposing to build a structure valued at more than $5,000 must have an Application for Construction Approval on file with the Zoning Administrator, and the ordinance adds that this applies to all structures regardless of intended use. The application form itself lists the kinds of projects the office sees.

The form asks whether the parcel is agricultural or residential and whether the building will have running water, insulation, a finished basement, heating and cooling, a concrete floor, electricity, a bathroom, a driveway and a 911 address, along with its estimated cost, square footage and dimensions.

What the county decides and what the state holds

Ordinance 2006-6 took effect on January 1, 2007, restating the original 1973 zoning ordinance and its amendments through 2001. It sets minimum dwelling sizes (600 square feet of ground floor for a one-story house, 560 square feet for a house of 1½ or two stories) but contains no building code, and the county pages describe no structural plan review. The Environmental Health page adds that a 2005 county radon ordinance requires every newly built home to include radon-resistant features.

Shelby County building department: who handles permitting

Tony Buman is the county’s Zoning Administrator. Under section 22.11 of the ordinance the Zoning Administrator is appointed by the County Engineer with the supervisors’ consent, and the office issues zoning certificates and occupancy permits, inspects for compliance and serves as secretary to the Planning and Zoning Board and the Board of Adjustment. Septic and well permits come from Environmental Health, directed by Luke Wolken, at the same Industrial Parkway address as the Engineer’s office.

The Engineer’s department maintains about 960 miles of road and nearly 250 bridges, split into ten motor grader districts of roughly 180 lane miles each.

Cities in Shelby County

The county ordinance stops at city limits, as Iowa Code 335.3, quoted on the Planning & Zoning page, requires; each city sets its own permit rules.

Shelby County permit types

The Application for Construction Approval is a two-page printable form: the first page describes the owner, parcel number, project type and use, and the second is a sketch of the construction (the form points to the county’s Beacon aerial map for reference) with a signed statement that the construction and use will comply with county ordinances. Mail or bring it with the $50 fee, by cash or check payable to the Shelby County Treasurer, to Planning & Zoning at the courthouse. Section 22.321 treats every construction application as an application for the occupancy permit as well.

Residential permits

In the A-1 Agricultural district a single-family house is a permitted use on 10 acres or more, with at least 300 feet of width, a front yard of 80 feet along state and federal roads or 60 feet along other public roads, 30-foot side yards and a 100-foot rear yard, and a height limit of 2½ stories or 30 feet (15 feet for accessory buildings). A house on a smaller lot needs Board of Adjustment approval: the ordinance allows estate lots of 2 acres or more, or a residence that has stood at least two years before the request, and homes on lots over 20,000 square feet served by an approved community or rural water system where the soils are Class III or less productive or the site cannot be farmed. Lots approved this way need an average width of 150 feet and a 120-foot front yard. The ordinance also lists R-1, R-5 Rural Village and RT Rural Transition districts for denser rural housing.

Commercial permits

Businesses use the same application, with uses sorted into the B-3 Interchange Business, I-1 Light Industrial and I-2 General Industrial districts and conditional uses decided by the Board of Adjustment after notice to owners within 500 feet. On March 17, 2026 the supervisors adopted four moratoria, Resolutions 2026-14 to 2026-17, on the siting, construction and operation of commercial solar energy systems, commercial battery storage, commercial digital asset mining and data centers, and commercial wind energy systems; each runs until July 1, 2027 while the county drafts ordinances. On May 5, 2026 Ordinance 2026-2 repealed the county’s 2022 hazardous liquid pipeline zoning rules after a federal appeals court ruling.

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

What comes before the building permit

• Septic and well. Environmental Health permits and inspects every new onsite wastewater system after a percolation test it conducts, and every new private, heat pump or monitoring well.
• Entrance. The Engineer’s entrance application for any new or widened access to a county road.
• Address marker. The 911 Center takes 911 marker orders online.
• Zoning relief. Variances, conditional uses and appeals go to the five-member Board of Adjustment; rezonings go through the Planning and Zoning Board to the supervisors.
• Flood plain. Development in the F-1 district, the Zone A areas on the county’s flood insurance rate map, must follow the county’s flood plain regulations.

Shelby County permit costs and fees

Zoning Ordinance 2006-6 sets the fees itself, and the current forms match it.

Because the $50 fee is flat, a $40,000 machine shed and a $450,000 house pay the same amount, while a $4,000 storage shed needs no application at all. Building without an application on file is a violation of the ordinance; fines can reach $750 for each infraction or $1,000 for a repeat offense, and each day a violation continues counts separately.

Trade permits and who may pull them

Shelby County’s pages describe no county electrical, plumbing or mechanical permits; the construction form only asks whether the building will have electricity, plumbing and heating. Wiring in the rural county therefore needs a state electrical permit and state inspection through DIAL, and plumbers and HVAC contractors work under their state licenses.

• Septic systems. Environmental Health permits and inspects all onsite wastewater systems installed in the county and requires a percolation test on every one.
• Wells. New private water wells, heat pump wells and monitoring wells are permitted and inspected, with a site assessment before drilling and an inspection when drilling is finished.
• Radon. New homes must include radon-resistant construction under the 2005 county ordinance; the office sells radon test kits.
• Field tile and utilities. Crossings of a county road need the Engineer’s tile crossing or utility permit.

The entrance application asks whether the applicant or a contractor will install the drive, and a contractor installer must send the Engineer a certificate of insurance, including general liability of $500,000 per occurrence and $1,000,000 in aggregate.

How to apply for Shelby County construction approval

Review, corrections and what causes delay

Section 22.322 asks for plans in duplicate and a scaled plot plan showing the lot, the building’s exact location, size and height, its use and the number of households; one approved copy is returned to the applicant. Projects slow down when a house lot is under 10 acres, when a parcel lies in the F-1 flood plain, where no permanent dwellings are allowed, or when the use is covered by one of the 2026 moratoria. The Board of Adjustment meets at its chair’s call and must publish notice before a hearing. Any lot pins disturbed by grading must be reset before building starts.

Inspections in Shelby County

The county’s building inspection is a zoning inspection at the end of the job. Under section 22.33 no occupancy permit is issued until construction is complete and the Zoning Administrator has inspected the premises and certified that they match the plans the zoning certificate was based on. A temporary certificate valid for up to six months can be issued while an addition is finished or a building is partly occupied, and a refusal must be explained in writing within 14 days of the request.

• Septic. Environmental Health inspects each new system it permits.
• Wells. A site assessment before drilling and an inspection once the well is drilled.
• Entrances. The Secondary Roads Department must be told 24 hours before an entrance is installed and again when it is finished (712-755-5954); unauthorized entrances in the right-of-way can be removed without notice.
• Wiring. State electrical inspectors.

Environmental Health also performs time-of-transfer septic inspections when rural property is sold, using a small backhoe to uncover the tank and distribution box when needed.

Iowa building code

Shelby County regulates rural construction through Zoning Ordinance 2006-6, the 2004 subdivision ordinance, its flood plain regulations and the Environmental Health permits; the ordinances the county posts include no building code, and its pages describe no construction inspections beyond the occupancy, septic and well checks. FEMA’s Community Status Book lists Shelby County as participating in the National Flood Insurance Program, with a current flood insurance rate map dated June 16, 2015.

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

Shelby County permit search and official resources

The Zoning Administrator keeps the county’s permanent records of maps, nonconforming uses, amendments, variances, appeals and applications, and the construction form carries an office box for entering it in the county’s CAMA property records, so the history of a parcel can be requested from Planning & Zoning. Supervisors’ agendas and minutes for 2026 are posted on the county site, and parcel lines and aerial photos are on the county’s Beacon map.
