Iowa Home Building Permits: Steps, Fees and Inspections

Last updated October 2026

A new house in Iowa needs a building permit, trade permits, a string of inspections and a certificate of occupancy. This guide walks the home building permit process step by step. It compares what six metro cities publish about applying, review time and fees, and shows how to check a contractor’s state registration before you sign.

TLDR: Inside city limits, your city issues the building permit. On unincorporated land, the county does. Plan on about one to two weeks of plan review in the metro. Ankeny’s own July 2026 example put the building permit for a 2,000-square-foot ranch at $2,240. Trade permits, inspections and a final certificate of occupancy follow, so verify your builder’s state registration first.

You found the lot, or you are close. Now someone mentions permits, and the project suddenly feels like paperwork instead of a house. You want to know who to call, how long it takes and what it costs.

Good news: the process is more predictable than its reputation. Below you will find who issues permits in Waukee, Johnston, Clive, Ankeny, West Des Moines and Urbandale. You will also get the steps in order, real fee math from city fee tables, and the inspections that decide your move-in date.

Who issues a home building permit in Iowa?

Your city’s building department issues the permit if the lot sits inside city limits. If the lot is in an unincorporated area, the county issues it. The state sets the code, but the paperwork, plan review and inspections happen locally.

That split is written into the state rule itself. When Iowa adopted the 2024 International Residential Code under Iowa Administrative Code 481-301.8, it deleted the code’s own administration sections, R103 through R114. Local building departments handle permits and inspections instead.

Which code edition your city enforces is a separate question. Our guide to Iowa residential building codes in 2026 covers editions, electrical changes and the radon law. This post sticks to process and fees.

The table below shows who handles a new-home permit in each metro city we checked, plus two counties, and how each one takes applications.

Every city on this list takes applications online or by email, and Johnston states outright that it will not accept incomplete applications. The county rows matter if your lot is outside town, because the rules and add-on permits change.

Pro Tip 1: Check jurisdiction before you buy the lot. A mailing address can say one town while the permit comes from the county.

Pro Tip 2: Ask whether the city requires local contractor registration. Clive, for example, requires contractors to register locally in addition to the state registration.

What are the steps to get a home building permit in Iowa?

Start with zoning and the lot, then submit a complete plan set, wait for review, pay, and build to inspections. Get the first two steps right and the rest moves on the city’s schedule.

Here is the order we follow on a new home:

1. Confirm the jurisdiction, zoning district, setbacks, easements and any subdivision covenants.

2. On rural lots, line up the county add-ons first. Dallas County, for example, requires a septic permit and an entrance permit before it issues a building permit.

3. Assemble the package: site plan, construction drawings, energy code documents and heating and cooling load calculations where the city asks for them.

4. Submit, answer plan review questions, pay the fees and post the permit.

5. Contact Iowa One Call at least 48 hours before digging, as Iowa Code section 480.4 requires.

6. Build to inspections, then pass the final for a certificate of occupancy.

The table below shows the review and timing figures that cities and counties publish themselves.

Review itself is short. Missing documents and the back-and-forth that follows are what stretch it out. Johnston’s permits and fees page says it plainly: incomplete applications will not be accepted.

Pro Tip 3: Submit the site plan with every required item the first time. Johnston’s checklist asks for a north arrow, adjacent street names, property lines and the dimensioned footprint.

Pro Tip 4: Send energy documents and load calculations with the plans. Ankeny’s building information page lists a separate email inbox for energy documents and Manual J and D reports.

Pro Tip 5: Call Iowa One Call before every new dig area, not just the first one. A locate notice is valid for 25 calendar days under the same statute.

Illustrative scenario: A family in Johnston submits a complete new-home package on a Monday, including the site plan checklist items. Plan review comes back in six working days with one question about a beam size. The answer goes back the same day, the permit issues the next week, and footings start about three weeks after submittal.

How much do home building permits cost in Central Iowa?

Most metro cities price the building permit from the project’s valuation, using a sliding table. Ankeny’s own July 2026 example, a 2,000-square-foot ranch with a finished basement and attached garage, came to $2,240. Expect trade permits and smaller fees on top.

The catch is that each city decides valuation its own way. Ankeny sets it by the square foot, at $175.92 for dwelling space as of July 1, 2026. Johnston uses the value added or the cost of construction, and Dallas County uses International Code Council cost data adjusted for Iowa.

To compare the tables fairly, the table below runs the same $400,000 valuation through each jurisdiction’s posted building permit fee schedule.

The same valuation produces fees about $1,350 apart across the metro. Urbandale’s figures come from its fee and fine schedule effective July 1, 2026. A higher city valuation per square foot can matter more than the table itself, so ask for the city’s estimate early. Johnston and Dallas County both note that the building official calculates the final fee.

Trade permits come next. The electrician, plumber and heating contractor usually pull their own permits, and several jurisdictions charge flat fees for a new house.

Trade permits add a few hundred dollars, while skipping a permit can double the fee. Budget the whole stack, not just the building permit.

Pro Tip 6: Ask your builder to list every permit and city fee as its own line on the estimate. Water, sewer and driveway fees can ride along with the building permit in some cities.

Pro Tip 7: If your plans change after the permit issues, tell the city before you build the change. Johnston charges a recalculation fee when the built project grows past the submitted plans.

What inspections does a new home need?

Plan on footing, foundation, under-slab plumbing, rough-in, framing and final inspections, in that order. Each one has to pass before the next stage gets covered up. The final inspection leads to the certificate of occupancy.

Johnston’s required list for a house is a good model. It covers perimeter erosion controls, footing, foundation, plumbing under slab, plumbing rough-in, electrical rough-in, framing and mechanical rough-in, and the final. Driveway approaches and curb cuts go through Public Works.

The table below lists the common stages, when they happen and what the inspector looks for.

Treat each visit as a scheduled milestone. A footing poured before inspection, or a locked door at the final, can cost days.

Local design criteria show up at the footing. Ankeny, Des Moines and Urbandale all list a frost line depth of 42 inches, so footings must sit at least that deep. Winter adds rules too: Johnston will not schedule concrete inspections when the forecast drops below 10 degrees within 24 hours.

Pro Tip 8: Keep property pins capped and visible at the footing inspection. Ankeny counts missing pins as a failed inspection, and a reinspection cannot be scheduled sooner than 24 hours later.

Pro Tip 9: Plan the final inspection around the occupancy timeline. Johnston needs at least two business days for a certificate of occupancy, so do not book movers for the day after the final.

Illustrative scenario: A couple in Ankeny pours footings in late November for a 2,200-square-foot two-story with an unfinished basement and a 600-square-foot garage. The city’s per-square-foot valuations put the building permit near $2,110, plus flat trade fees. A cold forecast pushes the footing pour three days, and the house is ready for its final inspection about ten months later.

What does a registered contractor handle, and can you manage it yourself?

A registered contractor pulls the building permit, assembles the plans, coordinates the trade permits and meets every inspector. You can take that on yourself in some cases, but you also take on responsibility for the work passing code.

This question shows up in our own search data. Homeowners search for what a general contractor actually does and how to manage a custom build themselves before they call. Our post on what a general contractor does in Central Iowa covers the scheduling side.

Iowa requires construction contractors who earn at least $2,000 a year to register with the Department of Inspections, Appeals and Licensing. The DIAL contractor registration page lists a $50 application fee and a link to check a contractor’s registration. People working only on their own property do not have to register.

Busy Builders is a registered Iowa contractor (DIAL registration C140184), based in West Des Moines. We have completed more than 1,285 projects across Central Iowa since 2020.

The table below separates what the state registration covers from what a city may add, and what an owner-builder takes on.

Registration shows a contractor is on the state’s books for unemployment and workers’ compensation. It is not a skills test, so references and past work still matter.

Pro Tip 10: Look up the registration yourself on the DIAL site. It takes a few minutes and confirms the business name on your contract matches the state record.

Pro Tip 11: Put permit responsibility in the contract in plain words. The contract should say who pulls each permit and who schedules each inspection.

Pro Tip 12: If you plan to act as your own builder, read your city’s trade rules first. Clive, for example, lets homeowners do their own trade work on an addition only when a homestead tax credit is on file.

Illustrative scenario: A family buys five acres in unincorporated Dallas County near Van Meter. Before the building permit, they secure a septic permit and a county entrance permit, which adds about three weeks. The building permit and three flat $80 trade permits follow, and construction starts within the county’s six-month window.

Frequently Asked Questions

Q1: Do I need a building permit to build a house in Iowa? Yes. Every city we checked requires one for a new house, and Dallas County requires a building permit for any structure on unincorporated land. Separate electrical, plumbing and mechanical permits usually go with it. Call your city or county building office before you finalize plans.

Q2: How long does it take to get a home building permit in the Des Moines metro? Plan review is often about one to two weeks once the package is complete. Ankeny publishes about five working days for residential plans, and Johnston says a typical review may last up to seven working days. Dallas County issues within ten business days of complete materials. Submit a complete package to avoid a second round.

Q3: How much does a building permit cost for a new house? It depends on the city’s valuation method and fee table. Ankeny’s July 2026 example for a 2,000-square-foot ranch with a basement and garage came to $2,240. On the same $400,000 valuation, posted tables range from about $1,465 in unincorporated Dallas County to about $2,818 in Urbandale. Ask the building official for an estimate before you set your budget.

Q4: Who issues building permits outside city limits? The county does, if your lot is in an unincorporated area. Polk County Building Services reviews plans, issues permits and inspects construction in unincorporated Polk County. Dallas County Planning and Development handles it in unincorporated Dallas County, after the septic and entrance permits. Confirm jurisdiction with the county before you buy rural land.

Q5: What inspections are required for a new home in Iowa? Expect footing, foundation, under-slab plumbing, rough-in, framing and final inspections, plus erosion control in some cities. Johnston’s published list follows that order and ends with the final inspection for a certificate of occupancy. Ankeny, Des Moines and Urbandale all list a 42-inch frost depth for footings. Schedule each inspection at least 24 to 48 hours ahead.

Q6: How do I check whether a contractor is registered in Iowa? Use the contractor lookup on the Iowa DIAL website. Contractors earning $2,000 or more a year from construction must register, and the state charges a $50 application fee. Some cities, like Clive, also require a local registration. Ask for the registration number before you sign anything.

Key Takeaways

• City or county: Your city issues the permit inside city limits; the county does on unincorporated land.
• Review is short: Metro cities publish about five to seven working days of plan review for complete residential packages.
• Fees follow valuation: The same $400,000 valuation produces building permit fees from about $1,465 to $2,818 across the posted tables.
• Inspections set the pace: Footing, foundation, rough-in, framing and final inspections each pass before the next stage is covered.
• Registration first: Check the DIAL registration, and any local registration, before you sign a contract.
