Missouri has no statewide building code, and that matters here

For most Missouri landowners this article is reassurance rather than warning, and it is worth saying that at the top rather than the bottom.

But there is a piece of Missouri that carries a question no other state in this network has to answer in quite the same way, and the reason is a combination of geology and the fact that Missouri governs construction differently from its neighbors.

Two facts that only matter together

The first is the New Madrid seismic zone, which runs across parts of seven states. In Missouri the exposure is concentrated in the southeast, in and around the bootheel, and the state’s own geological service is direct about what a large event there would do.

The second is that Missouri has no statewide building code. Codes are adopted and enforced by local jurisdictions, county by county and city by city. Arkansas, Indiana, Kentucky and Tennessee, all of which share the same fault system, set a statewide minimum. Missouri does not.

Separately, neither fact would decide much. Together they mean that what a building must be engineered to withstand in southeast Missouri depends partly on which jurisdiction it sits in.

What that changes for a landowner

If your ground is in the southeast, expect any serious party to raise it, and expect a site investigation to be more involved than it would be two hundred miles north. Seismic design is well understood and entirely achievable. It costs money, and cost moves a site down a list.

It also means the county’s code posture becomes part of the diligence rather than a formality. A jurisdiction that has adopted a current code with seismic provisions gives a developer a clear answer. One that has adopted nothing leaves the developer to work it out and to carry the uncertainty, and uncertainty is priced.

That is an unusual situation where less local regulation is not automatically more attractive to industry, which cuts against the usual assumption.

Why most of the state can set this aside

The zone is regional, not statewide. Ground in northern, central and western Missouri is not in the same position, and for those landowners the questions that decide the answer are the ordinary ones.

Distance to capable transmission. Which system serves you. Whether the block is contiguous, flat, and reachable by heavy truck. Whether the county has industrial zoning and has used it.

Those decide the overwhelming majority of Missouri cases, and none of them involve a fault.

What to find out if you are in the southeast

Whether your county or city has adopted a building code, and which edition. The county clerk or the building department can answer that in one call.

Whether your ground is on alluvial soil. Deep soft sediment amplifies shaking, and river bottom ground behaves differently from upland. If you farm it you already know which you have.

Whether the property has ever had a geotechnical investigation for any reason, a grain facility or a bridge or anything else. Old reports are useful and are sometimes still in a drawer.

The thing not to conclude

Southeast Missouri is not disqualified. The bootheel has flat ground, large fields, low land cost, and in places good transmission, and those are exactly the attributes that get a property looked at.

Seismic exposure is one factor among several. It belongs in an honest conversation and it does not end one.

How we work

We buy and option land for our own account, with our own money. Nobody here earns a percentage on a transaction, so nobody here has a reason to walk you into something that should not happen, and your property is not circulated to third parties.

Most Missouri ground we look at will not work for this, and the reason is almost always distance from capable power rather than anything exotic. When that is the answer you get it plainly and quickly, with the specific reason.

Send the county, roughly the acreage, and anything you have noticed nearby. Not sure is a perfectly acceptable answer to any question we ask. We check the public record at our own cost and come back to you either way.
