Here is the short answer most homeowners are hoping for. If your concrete project stays on your own property, sits at ground level, and replaces what was already there, you usually do not need a building permit in Des Moines.
And here is the part that catches people: the moment the work touches the street, the curb, or the public sidewalk, you do. That line runs closer to your house than most people think. It cuts straight through the middle of the most common concrete project in the city: the driveway replacement.
This guide lays out where that line actually sits. It covers which projects need a permit and which do not, who to call at the city, what the process looks like, and how the rules shift in Ankeny, Waukee, and West Des Moines. It reflects the rules as of mid-2026. Permit requirements can change, so treat the city’s own answer as final.
The Central Iowa Reality Check
In Des Moines and the surrounding Polk County metro, most ground-level residential concrete on private property needs no building permit when it replaces what was already there. A backyard patio. A garage slab. A private walkway. The portion of your driveway that sits entirely on your lot. These are normally yours to build.
What changes the answer is one of three things.
The work reaches the public right-of-way. The right-of-way is the strip of publicly controlled land that includes the street, the curb, and usually the sidewalk and a few feet beyond it. Your property line almost never sits at the edge of the pavement. It usually sits several feet back, which means the end of your driveway is very likely on public land.
The work changes the site rather than replacing it. Widening a driveway, adding a curb cut, paving more of the lot, or changing how water drains all bring zoning rules into play. A like-for-like replacement would not.
The work is structural. Retaining walls above the code height, footings, and foundations are building-permit territory everywhere, Des Moines included.
If your project does not do any of those three things, you are most likely permit-free. Keep reading anyway, because the exceptions are exactly where expensive mistakes happen.
Concrete Projects That Usually Do Not Need a Permit
These projects, done at grade on private property, typically require no building permit inside Des Moines city limits.
A backyard patio poured at ground level. Our concrete patio services in Des Moines projects rarely involve a permit at all, because a patio slab sits entirely on private land and supports nothing above it.
Replacing a private walkway or garage slab in its existing footprint. Like-for-like replacement is the key phrase. Same location, same size, same use.
The private portion of a driveway. The section from your garage down to where public land begins can generally be replaced without a building permit.
Small flatwork such as stoops, pads for air conditioners, and mower strips. At grade, on your lot, no structure above: no permit.
Two cautions before you take “no permit” to mean “no rules.” Zoning still applies. Setbacks from property lines and limits on total paved area still bind your project. And utilities still run under your yard. That brings up a legal requirement that applies to every one of these projects: Iowa One Call. State law requires calling 811 at least 48 hours before any digging so utility lines can be marked. It is free, it is the law, and it applies even when no permit does.
Concrete Work That Does Require a Permit in Des Moines
Driveway Approaches and Curb Cuts
The approach is the section of driveway between the street and the sidewalk, including the flared portion at the curb. It sits in the public right-of-way. The City of Des Moines requires a right-of-way permit to demolish and reconstruct it. Adding a new curb cut, or widening one, is permit work too. The city reviews it against standards for width, slope, and drainage.
This is the rule that surprises homeowners, because a full driveway replacement almost always includes the approach. In practice: replace the whole driveway, plan on a permit. If you are budgeting that project, our breakdown of how much it costs to replace a driveway in Des Moines covers where permit costs fit in the total.
Public Sidewalk Repair and Replacement
Under Iowa law, the property owner is responsible for maintaining the public sidewalk that borders their lot. When a sidewalk panel needs repair or replacement, a permit is required whether the owner does the work or hires a contractor. Des Moines runs a dedicated line for sidewalk and driveway permit questions at (515) 283-4536. Once a sidewalk is flagged as defective, the city can require repairs on a deadline. That makes this a permit process many homeowners meet whether they planned a project or not.
Retaining Walls Over 4 Feet
Under the building code used across Iowa, a retaining wall taller than 4 feet requires a permit and usually an engineered design. Note the measuring point. The 4 feet runs from the bottom of the footing to the top of the wall, not from the ground. A wall showing 3 feet above grade can pass 4 feet once the buried footing counts. There is one more trigger: surcharge. In plain terms, that means extra load pressing on the wall from above, such as a slope, a parked car, or a structure. A wall of any height holding back a surcharge can need a permit. Short garden walls stay permit-free; anything holding back real earth deserves a call to the city first.
New Structures and Structural Concrete
Footings and foundations for garages, additions, and other structures are building-permit work by definition. If the concrete holds up a building, the permit conversation starts before the excavator does.
Drainage and Lot Coverage Changes
Projects that expand paved area or redirect stormwater can trigger site plan review even when the concrete itself seems routine. Paving a large new parking area or regrading how water leaves the property are the typical examples. This is judgment-call territory, which is exactly when a five-minute call to the city saves a five-figure correction.
Who Handles Permits, and How the Process Works
Concrete-related permits in Des Moines run through the Permit and Development Center, the city’s consolidated permitting office within the Development Services department. It is located in the T.M. Franklin Cownie City Administration Building at 1200 Locust Street, and it handles applications, payments, plan documents, and inspection scheduling online.
Contact points worth saving: (515) 283-4200 and permits@dmgov.org for general permitting, and (515) 283-4536 for the sidewalk and driveway line.
For a typical residential right-of-way project, the process looks like this.
Confirm whether a permit applies. One phone call or email with your address and project description. The city can tell you exactly where your right-of-way line sits.
Submit the application. Right-of-way and sidewalk permits are simple applications. Projects involving site changes may need a basic site plan showing the lot, the work, and distances to property lines.
Receive the permit before work starts. Straightforward residential right-of-way permits generally move quickly. Build a small buffer into your schedule rather than pouring the week you apply.
Complete the work to city standards. Approach width, slope, thickness, and drainage all have specifications. This is where an experienced local crew earns its keep.
Pass inspection. The city verifies the work in the right-of-way meets its standards. Once it passes, the file closes and the concrete is officially yours to use.
Navigating City Codes with a Des Moines Concrete Contractor
Like-for-like backyard slab replacements often bypass full plan reviews. Curb-cut changes, public sidewalk connections, and drainage adjustments do not. Those need city oversight. A licensed local contractor who handles Des Moines permits every week keeps your installation inside the setback lines, right-of-way codes, and building regulations without you having to learn them first.
On a professionally installed project, the contractor normally pulls the permit. That arrangement matters for a simple reason: the permit holder answers for the work passing inspection. Some contractors ask the homeowner to pull the permit on work the contractor is performing. That shifts the responsibility onto you, and it is fair to ask why.
There is also a timing angle. Permit review adds days to a project schedule, and inspection adds a step at the end. A crew that works in Des Moines every week builds both into the calendar. Planning around weather windows too? Our guides to the best time of year to pour concrete in Central Iowa and pouring concrete in winter in Central Iowa cover how the season fits the schedule.
What About Ankeny, Waukee, and West Des Moines?
Each suburb writes its own rules, and they do differ. West Des Moines, for example, requires a permit for new sidewalk and driveway approach installation but not for straightforward repairs, a distinction Des Moines draws differently. Ankeny, Waukee, Urbandale, Clive, and Johnston each run their own permit offices with their own thresholds and fees.
The pattern across the metro holds, though: private, at-grade, like-for-like work is usually permit-free everywhere, and right-of-way work is permit work everywhere. What changes city to city is the paperwork in the middle. When your project sits in a suburb, the correct move matches Des Moines proper. Call that city’s building or engineering department with your address in hand before the project is scheduled.
What Skipping a Permit Actually Costs
The permit is the cheap part of a concrete project, typically a small fraction of one percent of the total cost. Skipping a required one carries real downside.
The city can require removal. Unpermitted work in the right-of-way can be ordered out at the owner’s expense. Tearing out fresh concrete and pouring it again is the most expensive way to build a driveway approach.
Fines and stop-work orders. Work in progress can be halted, which strands a project half-finished with a crew on the clock.
Trouble at sale time. Unpermitted site work can surface in pre-sale inspections and become a negotiating point, or a repair demand, at the worst possible moment.
Liability. If an unpermitted approach or sidewalk contributes to an accident or a drainage problem on neighboring property, the missing permit becomes part of the story.
None of this is meant to alarm anyone whose backyard patio never needed a permit in the first place. Most residential concrete in Des Moines genuinely is permit-free. The costs above belong almost entirely to right-of-way work done without asking, and they are entirely avoidable with one phone call.
Frequently Asked Questions
Do I need a permit to pour a concrete patio in Des Moines?
Usually not. A ground-level patio on your own property, poured at grade with no roof or structure above it, generally does not require a building permit in Des Moines. Zoning rules still apply, including setbacks from property lines and limits on how much of the lot can be paved, so the project still has to follow city code even without a permit. When in doubt, one call to the Permit and Development Center at (515) 283-4200 settles it before any concrete is ordered.
Do I need a permit to replace my driveway in Des Moines?
It depends on where the driveway ends. Replacing the private portion of a driveway in its existing footprint typically does not require a building permit. The moment the work touches the public right-of-way, meaning the approach where your driveway meets the street, the curb cut, or the section crossing the public sidewalk, a right-of-way permit from the city is required. Most full driveway replacements include the approach, so most of them do involve a permit.
Who issues concrete permits in Des Moines?
The City of Des Moines Permit and Development Center, part of the Development Services department, handles construction and right-of-way permits. It is located in the T.M. Franklin Cownie City Administration Building at 1200 Locust Street and can be reached at (515) 283-4200 or permits@dmgov.org. Applications, payments, and inspection requests can be handled online. Sidewalk and driveway permit questions have a dedicated line at (515) 283-4536.
Do I need a permit for a retaining wall in Iowa?
Short walls generally do not need a permit; tall ones do. Under the building code used across Iowa, a retaining wall over 4 feet tall, measured from the bottom of its footing to the top of the wall, requires a permit and usually an engineered design. Walls of any height that hold back extra load, such as a slope, a driveway, or a structure above them, can require a permit too. Local rules vary by city, so confirm with your building department before construction.
What happens if you pour concrete without a permit?
Unpermitted work in the public right-of-way can be flagged by the city, and the property owner can be required to remove or redo it at their own expense, on top of any fines. It can also complicate selling the home, since unpermitted site work can surface during inspections and title review. The permit itself is usually the cheap part. Skipping it is what gets expensive.
Do contractors pull the permit or does the homeowner?
Either can apply, but on a professionally installed project the contractor normally pulls the permit as part of the job. That is the arrangement you want, because the permit holder is responsible for the work meeting code and passing inspection. If a contractor asks you to pull the permit yourself on work they are performing, treat it as a warning sign and ask why.
