Foundation repair rules are set by the city or county your house is in, not by the contractor’s office address or your mailing address. Some cities are explicit. Des Moines requires a permit for helical and push piers. Its exemption for bowing-wall stabilization applies only to systems that do not alter the structure. Springfield, Missouri requires a Missouri-licensed registered design professional for foundation work covered by its rule on non-prescriptive repairs. Lincoln’s foundation-specific permit provisions were not independently verified for this guide. Most other cities apply a general “repairs and alterations need a permit” rule. Licensing is a patchwork: some states register contractors statewide, others leave it to cities, and only a few cities test general contractors.
How to work out which rules apply
- Find your jurisdiction. Use your city’s or county’s parcel tool, or call the permit office. Inside the Kansas City, St. Louis, Omaha and Oklahoma City metros especially, a mailing address doesn’t tell you which city issues the permit.
- Ask the permit office about your scope in specific terms: piers or underpinning, wall anchors or braces, excavation, interior drainage, sump installation. An answer about a different job doesn’t carry over.
- Check the contractor against the right record: the state registration or license where one exists, plus the city’s license or registration where your house is.
- Put it in the contract: who applies, who pays the fee, who schedules inspections, and whether an engineer’s design is part of the submittal.
State rules at a glance
| State | Statewide contractor requirement relevant to foundation repair |
|---|---|
| Kansas | No statewide general-contractor license (the state registers roofers only). Licensing is local. |
| Missouri | No state board for general or home-improvement contractors. Licensing is local. |
| Oklahoma | The Construction Industries Board says general contractors aren’t required to hold a state license. Trades are licensed. |
| Nebraska | All contractors doing business in the state must register with the Department of Labor. |
| Iowa | Contractors earning $2,000 or more a year must register with the Department of Inspections, Appeals, and Licensing. |
| Arkansas | Qualifying single-family work over $2,000 generally needs the appropriate residential license; specialty work and major structural remodeling use different license categories. |

City by city
What each city publishes, as we found it on October 28, 2026. “Ask the city” means we didn’t find a published rule naming foundation work. It doesn’t mean no permit is needed.

The table lists published frost-design values or standard details. Project-specific exceptions, approved designs and local amendments can affect footing requirements. These figures do not establish whether an existing foundation is adequate.
What a permit does and doesn’t tell you
A permit is the city’s authorization for specific work. Inspections are separate milestones. Ask for the final inspection or closeout, not just the permit number. Neither one certifies workmanship or guarantees the repair will perform. Where a city requires engineering, as Springfield now does and as some proposals include voluntarily, the engineer’s sealed design and final report are the documents that describe what was supposed to be built.
How permit history shows up on our company records
For Kansas City, Missouri, we matched historical permits in the city’s open-data permit dataset to five companies: 143 issued or closed foundation-related permits between October 1, 2021 and May 9, 2025. Those counts are history, not current workload or quality, and a blank means no match was joined. We haven’t joined permit data for other cities. See the Kansas City permits and licensing guide for how that sample was built.
