Topeka metro · Kansas

Metal buildings in Topeka.

From Topeka to Silver Lake, Rossville, Tecumseh and Carbondale, we help customers plan workshops, garages, agricultural buildings, barndominium shells and commercial facilities across Shawnee and Osage counties.

Where you’re building matters. City limits, intended use, local permitting requirements and engineering can all affect which building system makes sense for your project.

Permitting across the Topeka metro

The first question on any Topeka-area project is which authority actually governs your address. It is not always the one the mailing address suggests.

Unincorporated Shawnee County uses Topeka’s code

This is the detail most people are surprised by. Shawnee County adopted its own building code in 2017 and amended it in 2018, and the code it adopted is Title 14, Building and Construction, of the City of Topeka Code, incorporated by reference. The county did that deliberately, to keep building practice in the unincorporated area consistent with the city.

So moving your project outside Topeka city limits does not move you to a looser standard. It moves you to the same standard administered by a different office.

The county also administers its code through an Affidavit of Code Compliance, which must be notarized and must accompany any improvement requiring a building permit. It is a declaration by whoever is responsible for the work that it will comply with the applicable codes. Permits are issued by the Shawnee County Land Use & Development Department, 1515 NW Saline St, Topeka — (785) 251-5410.

The three-mile jurisdiction

There is a band of unincorporated land extending three miles beyond Topeka’s city limits where the city retains a say. Any division of land inside that area has to be approved by the City of Topeka Planning Department before you can apply for a county building permit.

That matters if you are splitting off a parcel to build on. It is a sequencing problem rather than a design problem, but it is the kind of thing that stalls a project for weeks if nobody flags it early. City Planning, (785) 368-3728.

Inside Topeka, and in Osage County

Projects inside Topeka city limits permit through the city directly. Topeka Permits, 515 S Kansas Ave, (785) 368-3905.

Carbondale and the ground south of the metro sit in Osage County, which is a separate authority with its own requirements. Incorporated towns within it permit inside their own city limits. We confirm what applies to a specific Osage County address before drawings are produced rather than assuming it matches Shawnee.

How the agricultural exemption actually works

Kansas law limits what counties can require of agricultural buildings. Under K.S.A. 19-2908, county zoning regulations do not apply to land used for agricultural purposes or to buildings erected on it for those purposes, so long as they are used for agricultural purposes and not otherwise. A 2016 Kansas Attorney General opinion goes further, concluding that a county may not require buildings used solely for agricultural purposes to comply with county construction codes.

Three things are worth understanding before you count on it.

It restricts counties, not cities. Inside an incorporated city, the municipality sets its own requirements and this limitation does not apply.

Floodplain regulations still apply in designated floodplain areas, whatever the building’s use. In the Kaw Valley that is not a footnote.

And Kansas statute does not define “agricultural purpose,” so the county makes that determination, usually through an application and a written determination rather than automatically. A building that is part agricultural and part something else may not qualify.

Risk category and engineering documentation

The risk category assigned to your building depends on its intended use and on the code provisions your jurisdiction enforces, not on its size alone. A building people occupy regularly is generally treated differently from unoccupied storage, but the classification and the documentation that follows from it are determined by the applicable code and the reviewing authority.

What that means in practice is that the engineering package your project needs depends on where it is going and what it is for. We confirm which authority governs your address and what they require before drawings are produced, so the documentation matches what will actually be reviewed.

Why engineering can change the price

Two buildings with identical dimensions can have different total costs depending on the engineering documentation required for their sites.

For example, when a qualifying agricultural building can use an accepted generic engineering package, tubular steel may offer a significant cost advantage. When site-specific engineering is required, the comparison can change.

We evaluate engineering costs alongside the building package, rather than treating them as an afterthought. That can make a difference in which structural system offers the lowest total cost for your project.
