Permitting & Engineering in Texas

These two go together because one is useless without the other: a Texas plan reviewer will not pass a clear-span building without a set sealed by a Texas-licensed engineer, and an engineered set is worth nothing until somebody carries it through review. We do both. Structural engineering against your jurisdiction’s adopted criteria, then the submittal, the comment cycles, and every inspection through to certificate of occupancy. Where the parcel sits outside any city, that work looks different rather than disappearing — the inspections still have to happen, and the statute puts the job of arranging them on the builder.

How a permitting & engineering project runs

Four stages, in this order. The sequence matters more than it looks: getting engineering and permitting settled before anything is fabricated is what keeps a build from stalling.

1

Jurisdiction and zoning check

First we establish who actually has jurisdiction — the city, an opted-in county, or nobody — and check the deed restrictions, because outside a city those bind where zoning does not exist. Getting this backwards costs months.

2

Structural engineering

A Texas-licensed engineer analyses the frame against the design criteria your jurisdiction adopted, then seals the foundation, anchor bolt layout, framing and connection details. A seal from an engineer not licensed in Texas is rejected regardless of how sound the engineering is.

3

Assemble and submit

Sealed plans, energy calculations, wind-load documentation, truss engineering, product approvals, site plan, and the ancillary approvals like septic and driveway that reviewers ask for late.

4

Comments through to CO

We answer review comments quickly, then schedule and meet every inspection from footing to final, and close the permit out to a certificate of occupancy.

Who is actually in charge

A Texas county has no general building-code authority over your land

Local Government Code Chapter 233 is the whole of a county’s power over structures, and there is no general building-code subchapter in it. The residential building code standards at Subchapter F are opt-in: §233.152 applies them only to a county whose commissioners court has adopted a resolution or order taking them up. Even where a county has opted in, the subchapter is deliberately light — §233.153(d)(1) says it may not be read to require prior county approval before construction begins, §233.153(f) forbids the county from charging a fee, §233.153(d)(2) grants no zoning power, and §233.154(a)(3) has the builder contract the required inspections privately. So in an opted-in Texas county there is a code but no permit, no fee, no county inspector and no county plan review. Inside a city limit the answer is completely different, and that is the whole point.

Serving clients across the entire region

We deliver permitting & engineering across Texas, and what the job has to satisfy changes with the parcel. Inside a city limit you are under that city's adopted code and its own filled-in Table R301.2. Outside one, a county has no general building-code power unless it has opted in — and even then there is no county permit and no county inspector. Two parcels twenty miles apart can carry completely different engineering. Tell us where the land sits and we will tell you which rules land on it.

What actually decides the price

Square footage is the number everyone leads with, and it is rarely the one that moves a barndominium budget. These four do.

  • Which of the three situations your parcel is in

    Inside a municipality you are on that city’s adopted and amended code, with its permit and its inspections. In the unincorporated area of a county that has opted into Subchapter F there is a code standard but no county permit and no county inspector. In a county that has never adopted it there is no county residential building code at all. Three different submittals, three different timetables, and the line between them is a boundary on a map rather than a matter of opinion.

  • Whether a city’s extraterritorial jurisdiction reaches you

    Extraterritorial jurisdiction is keyed to the city’s population, and a city of 100,000 or more carries it five miles beyond its limits — a large ring of exactly the land barndominium buyers look at. What that gets you is a platting question rather than a building-code question, and platting can carry real cost in surveying, street and drainage specifications and time.

  • The jurisdiction’s own published fee schedule

    These are published numbers, and they vary enormously. Waco prices a residential building permit at $0.35 per square foot, with a $60 plan submittal fee and a $15 technology fee, and states that working without a permit doubles the fees. Dallas prices a new single-family permit on square-footage tiers with plan review charged separately. A county that has opted into Subchapter F may not charge a fee at all. Read the schedule that applies to your parcel rather than an average of everyone’s.

  • Engineering already in hand

    If the sealed structural package exists and is correct for the criteria that actually apply to your parcel, permitting is administration. If it does not, permitting is engineering with a queue in front of it. On expansive clay and on the designated coastal counties that engineering is not optional, so it is better treated as part of the programme than as a surprise in the middle of it.

Permitting & Engineering in Texas: common questions

8 questions we get asked most often about building in Texas. If yours is not on the list, ask it directly.

Start your project
Do I need a building permit to build a barndominium in Texas?
It depends entirely on where the parcel is, and Texas has three genuinely different answers. Inside a city limit, you deal with that city and its adopted building code, and you get a permit, plan review and inspections in the ordinary way. In the unincorporated area of a county that has adopted the Subchapter F residential building code standards, there is a code — but §233.153(d)(1) says the subchapter cannot be read to require prior county approval before construction begins, §233.153(f) forbids the county to charge a fee for enforcing the standards, and §233.154(a)(3) makes the builder contract the inspections privately. There is no county permit to apply for. And in a county that has never adopted the subchapter at all, there is no county residential building code. That third answer is the one visitors find hardest to believe, and it is correct. Which counties have actually adopted is a county-by-county fact that has to be confirmed against the county’s own resolution or order, never assumed.
My county says it has no building code. Is that really true, and does anything still apply?
The first half is often literally true. Chapter 233 contains a shoreline subchapter, building and set-back lines, a fire code subchapter, alarm systems, the opt-in residential standards and a miscellaneous subchapter, and no general building-code power anywhere. County fire-code authority exists only for a county over 250,000 or one adjacent to such a county. But quite a lot still applies. Where the county has opted in, §233.154(a)(1) requires a minimum of three inspections on a vacant lot — foundation before the concrete is placed, framing and mechanical before covering, and one on completion — and §233.154(a)(3)(A) sets out exactly who may perform them. The list is short and specific, and it includes a licensed engineer, a professional inspector licensed by the Texas Real Estate Commission, a municipal plumbing inspector licensed by the Texas State Board of Plumbing Examiners, a building inspector employed by a political subdivision, and an inspector certified by the International Code Council as a residential combination inspector. The builder’s pre-construction notice has to state the version of the IRC that will be used, under §233.154(b)(3). Failing to give notice is a Class C misdemeanor under §233.157(b), and §233.157(c) exempts an individual who builds it themselves or acts as their own contractor and intends it as their primary residence — both limbs are required, not either one. Separately from all of that, the state energy code, the plumbing licence, the septic permit, floodplain regulation and any recorded deed restrictions apply regardless of what the county does.
Which edition of the code will my plans be held to?
Texas has two different frozen dates, and which one you are on depends on which side of a city limit you are standing. For municipalities, §214.212(a) fixes the residential code at the IRC as it existed on 1 May 2012. For the unincorporated area of a county that has opted into Subchapter F, §233.153(a) says construction shall conform to the version of the IRC published as of 1 May 2008, or the version applicable in the county seat of that county — a date rather than an edition name, and what was actually in print on that date was the 2006 edition. The statute is written as a choice between two limbs and does not say who elects between them; the nearest thing to an answer is §233.154(b)(3), which has the builder name the version in the pre-construction notice. And then the crucial part: §214.212(c)(1) lets a city adopt local amendments that add, modify or remove requirements set by the code, with no stringency floor, no ceiling and no state review, and no state registry of local amendments exists. A city can start from the 2012 code and delete from it. That is why no statewide statement about “the code in Texas cities” is ever safe, and why we confirm the adopted edition and the local amendments for your jurisdiction rather than working from a national summary.
My land is outside the city limits but inside its ETJ. Whose rules apply?
This is the question that costs people the most money, so here is what Texas courts have actually held. In Town of Lakewood Village v. Bizios in 2016 the Supreme Court of Texas held that a general-law city has no authority to enforce its building codes in its extraterritorial jurisdiction, and that §233.153 and §214.904 neither confirm nor grant such authority — §233.153(c) is a precedence rule, not a power. The Court expressly left the home-rule question open, and the Dallas Court of Appeals closed it in 2018 in Collin County v. City of McKinney, holding that McKinney, a home-rule municipality, lacks authority to enforce its building codes and related building inspection requirements within its ETJ, because every municipality requires legislative authorization to enforce building codes beyond its corporate limits and the court could find none. But read the rest of that holding, because the landowner lost the other half: the court held the city does have authority to require a landowner to plat its property, and in that case the dispute was over a driveway. So the useful summary is that a city generally cannot make you build to its code out there, and it very much can make you plat. The Supreme Court has never decided the home-rule building-code point itself, and a recorded development agreement can bind you by consent for decades. Ask the city what it claims, and read the title commitment.
Can I get my land released from the ETJ?
Sometimes, and it is much more available than it was. Legislation in 2023 created two routes in Local Government Code Chapter 42: a release by petition, where more than half the registered voters or the owners of a majority in value of the area can require it, and a separate petition-and-election route. Release is one-way — land cannot be brought back in or annexed without the owner’s own request. In Elliott v. City of College Station in May 2025 the Supreme Court of Texas said the statute “does not give the City discretion to deny a release petition. Release is a matter of paperwork,” and that the statute is presumed constitutional and remains the law. The exclusions matter as much as the rule, though, and one of them is aimed straight at suburban buyers: in the large-metro bracket the routes do not reach lots under twelve acres, or a single lot within a subdivision of twenty-five or more lots, and military buffers, industrial districts and strategic partnership areas are carved out too. So it is largely a large-acreage remedy, and it should never be described as generally available. Release also changes who regulates rather than whether: on release, subdivision regulation passes to the county.
Does Texas require a licensed contractor to build a house?
No, and it is worth understanding rather than glossing over. Texas has no state licence, registration or certification for a general residential contractor or home builder. The Texas Residential Construction Commission was created in 2003, went through Sunset review in the 81st Legislature and was not continued, nothing replaced it as a licensing body, and its statute is gone from the Property Code. The Texas Department of Licensing and Regulation runs 41 programmes — electricians, air conditioning contractors, industrialized housing, water well drillers among them — and not one of them is a general, residential or building contractor licence. So there is no such licence to hold, and nobody in this trade in Texas holds one, ourselves included. That is why you should be sceptical of anyone advertising as a licensed home builder in Texas. Two qualifications belong with that. A builder of industrialized housing does have to register with TDLR under Occupations Code §1202.102, and individual trades are licensed — including the plumber, because §1301.052 excludes plumbing performed in conjunction with new construction from the rural exemption, so a licensed plumber is required even where there is no county code, no permit and no inspector. What Texas has instead of a licence beforehand is liability afterwards: Property Code Chapter 27, the Residential Construction Liability Act, defines a contractor purely by conduct, mentions no licence anywhere, requires a specific boldface contract disclosure under §27.007, runs a 60-day notice-and-repair process, and since its 2023 amendments makes waiver of the chapter void under §27.009. Texas regulates builders through the courts after the fact rather than through a licence before it.
Would going modular mean fewer rules out in the county?
It is the opposite, by a wide margin, and this is the single most counter-intuitive fact in Texas residential construction. Industrialized housing under Occupations Code Chapter 1202 is held to the 2021 IRC, IBC, IFGC, IMC, IPC and IEBC, the 2015 IECC and the 2020 NEC, and §1202.203(b) makes a third-party on-site inspection mandatory outside a municipality, on top of factory inspection and state design review. A site-built house on the same unincorporated land is held only to the §233.153(a) floor, or to nothing at all if the county never opted in. So on rural land, modular adds oversight rather than removing it. It also usually does not apply to a barndominium anyway: §1202.002(c)(1) says industrialized housing does not include housing constructed of a sectional or panelized system that does not use a modular component, so a flat-packed kit is expressly not industrialized housing. The test is closed versus open construction — whether the off-site work prevents the building being adequately inspected at the site without damage or removal and reconstruction — and it turns on neither factory origin, nor material, nor the word “kit”. Note also that Chapter 233 excludes manufactured housing under Chapter 1201 and modular homes under Chapter 1202 from “new residential construction” entirely, and that those are separate regimes with separate agencies and their own visible markers.
How long will the permit take?
Inside a city, §214.904 puts a municipality under a 45-day deadline to grant or deny a permit application, with a fee refund attached if it misses, and that municipal deadline does reach into the extraterritorial jurisdiction. There is a separate county deadline, but it is narrower than people assume: §233.901’s 45-day requirement applies only to a county with a population of 3.3 million or more, which is Harris County alone, and it expressly excludes on-site sewage disposal permits. Do not let anyone sell that to you as a statewide 45-day rule. In practice the item most likely to hold a rural project up is not the building permit at all — it is the septic authorization, which runs on its own 30-day statutory clock behind a site evaluation, and for cities above 100,000 population a newly adopted code amendment carries its own 21-day notice and 30-day delay before it can be enforced. The way to compress the timeline is to have the engineering, the site evaluation and the plat question settled before anything is submitted, which is the part we take off you.
