Pottawattamie County’s Office of Planning and Development, on the first floor of the courthouse at 227 South 6th Street, Suite 157, Council Bluffs (712-328-5792; inspection requests 712-328-5847), permits and inspects construction in the unincorporated county through its Building Division, with zoning, floodplain, septic and well permits from its other divisions and applications online. At close to 960 square miles it is the second-largest county in Iowa by area, after Kossuth, and its territory divides into three quite different building environments: the Missouri River bottoms in the west, the Loess Hills running north to south through the middle, and the rolling farmland east of them.
Those conditions differ in nearly every respect that bears on a building. The bottoms carry floodplain, high groundwater and levee considerations; the Loess Hills bring slope stability, erosion and difficult wastewater siting on deep windblown silt; the eastern farmland behaves like ordinary Iowa. The code is whatever the county has adopted under Iowa Code chapter 103A, identical across all three, while the statewide provisions — energy conservation, the state fire code, the state plumbing and electrical codes — apply regardless.
This guide covers unincorporated Pottawattamie County. Council Bluffs, Carter Lake, Avoca, Oakland, Walnut and Treynor permit their own construction; the state across the Missouri to the west has an entirely separate framework.
Three building environments, one code. The county runs from Missouri River bottoms with floodplain and high groundwater, through Loess Hills with slope, erosion and difficult wastewater siting, to ordinary rolling farmland. The adopted code is the same across all three; the site conditions decide most of what a project actually costs, and they change within a few miles.

- Construction, alteration, repair, demolition or change of occupancy in unincorporated territory
- Zoning and subdivision approval from the county ahead of the building permit
- A statement of compliance with applicable energy conservation requirements, on every application except a one- or two-unit residential remodel
- New buildings, additions and structural work on an existing building
- Alterations, repairs and renovations, and any change of occupancy
- Decks, accessory structures above the local threshold, retaining walls and swimming pools
Often exempt
- Ordinary repairs and small accessory work below the county's adopted threshold, and one- and two-unit residential renovation from the energy statement requirement
- Ordinary repairs that do not alter structure, egress or systems
- Painting, papering, flooring, cabinets and similar finish work
- Small accessory structures below the locally adopted threshold — zoning still applies
- Renovation and remodelling of one- and two-unit residential buildings, from the energy statement requirement
What is local, and what applies regardless
The general building code is Pottawattamie County's choice. It may adopt the state code by ordinance, adopt something else, or adopt nothing; where it adopts the state code it may also adopt its own administrative and enforcement provisions, establish a building department and designate a building official. What is not its choice is the statewide core: the energy conservation requirements, which apply to all commercial construction and to new one- and two-family residences whether or not a local code exists; the state fire code, enforced by the State Fire Marshal with local fire departments acting under agreement; and the state plumbing and electrical codes. Beyond those, the three distinct terrains the county spans and the conditions each imposes on a build.
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

Permit types
Residential permits
A house in unincorporated Pottawattamie County is permitted by the county against the code it has adopted, with zoning cleared first, the energy compliance statement filed, and well and on-site wastewater approvals where the parcel is unserved. Which of the county's three terrains the parcel sits in determines the foundation, the access and the wastewater position, and that should be established before design.
Commercial permits
Commercial work in unincorporated Pottawattamie County — grain elevators, the interstate corridor and the logistics development spilling east from the metropolitan area — clears county zoning and subdivision, then plan review against the county’s adopted code, with the statewide energy requirements applying to all commercial construction. Farm buildings used for agriculture are outside a county building code (Iowa Code 331.304) and, except in floodplains, county zoning (Iowa Code 335.2).

Call 1-855-478-4290 →Establishing what applies to the site
In unincorporated Pottawattamie County the Missouri River bottoms carry floodplain, high groundwater and levee considerations, the Loess Hills bring slope and erosion into siting, and the state line across the river to the west marks an entirely separate regulatory regime.
Iowa contractors register with the state licensing department (DIAL), and electricians, plumbers and mechanical contractors hold state licences. Iowa rules
Pottawattamie County permit costs and fees
Fees follow the county's schedule for unincorporated territory, with site and wastewater evaluation a construction cost rather than a permit one.
| Item | Fee or rule |
|---|---|
| Building permit | The county's fee schedule, for unincorporated territory |
| Zoning and subdivision | County approval ahead of the permit |
| Well and on-site wastewater | Separate approvals; siting varies sharply by terrain |
| Trade permits | Electrical, plumbing and mechanical, each separately |
| Energy statement | Required with the application; no separate fee |
| City permits | Council Bluffs and the smaller cities issue their own |
A few miles changes the whole budget. Between the river bottoms and the Loess Hills the foundation type, the wastewater system and the access road can all change completely within a short distance. Two parcels of the same size and zoning in this county can carry materially different build costs, and the difference is set by the ground rather than by anything on the permit.

How to apply for a Pottawattamie County building permit
The state code, another code, or none at all — though a city of more than 15,000 people must enforce at least the state code.
Energy conservation, accessibility, the state fire code and the state plumbing, mechanical and electrical codes run statewide.
Zoning and subdivision are local in every case and precede the building permit.
DIAL contractor registration, state trade licences, and any local registration for general contractors.
Required on every building permit application except one- and two-unit residential remodelling.
Footing to final, with the trades on their own permits, then the certificate of occupancy.

Pottawattamie County reviews unincorporated work against its adopted code across a very large area. What delays a project here is a design carried between terrains, a wastewater evaluation started late, and a missing energy compliance statement.
Inspections in Pottawattamie County
Inspections follow the sequence of the code the jurisdiction has adopted — footing, foundation, framing, rough trades, insulation and final — requested from the local building department by permit number, with the trades inspected on their own permits. Work that passes final receives a certificate of occupancy for new buildings and changes of occupancy. Pottawattamie County inspects the work it permits in the sequence its adopted code sets, with the trades inspected on their own permits; the county's size makes inspection scheduling worth planning rather than assuming.

How large is the county?
Close to 960 square miles, the second-largest county in Iowa by area after Kossuth, spanning river bottoms, the Loess Hills and rolling farmland.
Does the county permit inside Council Bluffs?
No. Council Bluffs and the county's smaller cities permit inside their own limits; the county covers unincorporated territory.
Does the terrain change what I can build?
Substantially. Foundation type, wastewater siting and access all differ between the bottoms, the hills and the eastern farmland, though the adopted code is the same throughout.
What is the energy compliance statement?
A statement that the construction will comply with all applicable energy conservation requirements, required on every Iowa permit application except a one- or two-unit residential remodel.
Which code does the county enforce?
The code Pottawattamie County has adopted; under Iowa Code chapter 103A each jurisdiction chooses its own.
Does my Iowa licence work across the river?
No. The state across the Missouri has an entirely separate framework, licensing and permitting process.
