Commercial Construction in Karnes City, TX

Karnes City wants engineered plans before it issues a permit

You are putting up a shop, an office, a store, or a yard for your crews. Karnes City reviews engineered building plans before it issues a commercial permit, and owners who arrive without them wait weeks.
NTEX Construction builds commercial space in Karnes City and across Karnes County. Our shop sits in Goliad, about 38 miles southeast. Family owned and operated, so an owner answers the phone and an owner runs your job. Call (361) 645-4000 and tell us what you are building. For a house rather than a commercial building, start with new home construction in Karnes City.

Not sure which bucket you fall in? Call. We will tell you straight if it is our kind of job.

Every day you are closed costs you money

That is the part most contractors skip over.

A store shut down for a remodel is a store making nothing. A clinic that loses three exam rooms loses three rooms of patients. We build the schedule around that.

Sometimes that means phasing the work so half your floor stays open. Sometimes it means nights and weekends. Sometimes we stage the whole job so the loud, dusty part lands in one short window instead of dragging across a month.

We talk about this in the first meeting, before anyone draws anything. Tell us what you cannot afford to shut down and we build around it.

Commercial permits in Karnes City run on two tracks

Inside the city limits you deal with City Hall. Out on county land you deal with Karnes County, and the county issues no building permits at all. Which office you answer to is the first thing we settle on any Karnes City job, houses included.

Engineered plans first

Karnes City asks that plans for any type of commercial project arrive with engineered building plans attached for review before it issues a permit. City Hall sits at 1007 N. Hwy 123, phone 830-780-3422.

County land, no building permit

Karnes County issues no commercial building permits. What it does handle is septic, driveway and culvert work through Road and Bridge, and your 911 address. Permit office, 210 W Calvert Ave., Suite 155, phone 830-780-3511.

Septic before anything else

A county site needs a determination development permit application before the septic application goes in. Start it early, because nothing else moves until the system is settled.

State accessibility review at $50,000

Any commercial project in Texas with a construction cost of $50,000 or more gets registered with the Department of Licensing and Regulation, reviewed by a registered accessibility specialist, and inspected after construction. Registration runs $175.

We track all of it. You get a straight answer when you ask where things stand.

The ground under your slab is a Vertisol, and it moves

The Monteola clay under Karnes City is a Vertisol. Karnes County is where the USDA described the series in the first place. It runs 40 to 60 percent clay.

In a dry summer that ground splits open. Cracks run an inch or two wide and reach twenty inches down, sometimes further. Water pours straight into them. Then the clay swells shut and the next rain barely soaks in at all. Every year.

A warehouse slab puts far more surface on that ground than a house does. Get it wrong and you get cracked floors, doors that stick, and racking that no longer sits level. The same clay is hard on bare steel, so buried pipe and conduit need the right coating.

We start with the dirt. Soil work first, a slab engineered for what that ground actually does, and grading that moves water off the site instead of letting it pool at your foundation.

Metal buildings, poured right

A lot of Karnes County work is metal. Shops, storage, equipment barns, small warehouses, and yard buildings for oilfield crews.

We do the whole thing. Slab, anchor bolts, erection, doors, insulation, and the interior if you want office space inside it.

The slab is the part people underestimate. A metal building is only as square as the concrete under it, and on this clay that concrete gets designed rather than guessed.

How a commercial job runs with us

We meet on site

You show us the space or the lot. We ask what the building has to do for your business.

We draw and price it

You see the plan and the number together, before anything starts.

We get the plans engineered

Karnes City needs them stamped before review. On county land we start the septic determination at the same time.

We handle the approvals

City permit, county septic and driveway, 911 address, and state accessibility registration once the job clears $50,000.

We schedule around you

Phasing, after-hours work, whatever keeps your doors open.

We finish and hand it over

Weekly updates, and you can walk the site any day you want. Final inspections, accessibility inspection, punch list. We fix the list before you open.

NTEX did a major remodel for me and did an excellent job!!! All the contractors were pleasant and easy to work with. And their work was top-notch. I recommended them to friends who ultimately used them and they too were very pleased with their work!!!

Caren Adamson

NTEX recently did a remodel of our Sacristy and Narthex at Christ The Victor Lutheran Church. We were very pleased with the work they did. The men were friendly and courteous - and they cleaned up after themselves. We will definitely consider using them for other projects!!!

Christ Victor

I highly recommend NTEX construction. I have worked with NTEX on one major office build, one bathroom remodel, and am currently working with them on 2 bathroom remodels. Our office was completed in record time and is amazing. The bathroom remodel is spot on and was done in a very timely manner despite many other things going on. The current projects are on mark and looking to be completed on time.

I love working with everyone at NTEX. They do quality work, are very timely, and fun to work with!

Frequently Asked Questions

How long does a commercial build take in Karnes City?

It depends on size and how much approval the job needs. A finish-out inside existing walls moves fast. A new building on raw land takes longer, and getting plans engineered and reviewed is usually the slow part. We give you a real schedule up front and tell you the day it changes.

What counts as engineered building plans?

Drawings stamped by a licensed engineer. The city asks that plans for any type of commercial project arrive with engineered building plans attached before a permit is issued. We bring our own engineer in early, because showing up without the stamp is the most common reason an owner’s permit stalls.

Do you handle the permits and inspections?

Yes. The city permit, county septic and driveway work, the 911 address, and the state accessibility registration once the job clears $50,000. You sign where we point.

What is the accessibility review everybody warns me about?

Texas requires any commercial project costing $50,000 or more to be registered with the Department of Licensing and Regulation and reviewed by a registered accessibility specialist, with an inspection after construction. It covers door widths, restrooms, ramps, and parking. Registration is $175. We build to it from day one so nothing gets torn out later.

Do you build outside the Karnes City limits?

Yes. We work across Karnes County and the Crossroads. County jobs skip the city permit, because the county issues no commercial building permits. What those jobs do need is septic, a driveway or culvert permit from Road and Bridge, and a 911 address. Kenedy is six miles south on US 181, and we build there too. See commercial construction in Kenedy.
