Before you pay anybody to draw anything
Architect vs. draftsman. Texas already answered it
Almost everything written about this treats it as a judgment call about budget and taste. In Texas it is a question of statute first, and for a house the statute is unusually blunt. The decision worth your attention is a different one, and it is about the engineer — a profession most people never think to ask about.

The part nobody quotes
Your house is exempt. At any size.
The Texas Architects Act lists the people it does not apply to, and one of them is whoever is drawing your home. It is not a loophole and it is not a gray area — it is a clause, and it has been sitting there the whole time you have been wondering.
“This chapter does not apply to a person who… prepares the architectural plans and specifications for… a single-family or dual-family dwelling or a building or appurtenance associated with the dwelling.”
Read what is not in it. No square footage. No number of stories. A twelve-thousand-square-foot custom home sits on the same clause as a twelve-hundred-square-foot one. The exemption reaches “a building or appurtenance associated with the dwelling” too, which is the language a garage or a garage apartment lands under.
And there is a second one
A separate branch, § 1051.606(a)(3), exempts the alteration of any building — not only a house — unless the alteration involves a substantial structural or exitway change to the building. That is the clause a remodel usually lives on, and its hinge is the phrase “substantial structural… change.”
Not sure which clause your project sits on?
Tell us what you’re building“Under 5,000 square feet and you don’t need an engineer.”
A real number, attached to the wrong building
That sentence is a misreading of a real statute, and it is repeated confidently enough that homeowners plan around it. The number exists. It is simply attached to a different kind of building.
What people think it says
A house under 5,000 square feet is exempt from needing an engineer.
Wrong branch.
What it actually says
The 5,000-square-foot figure belongs to branch (F) — a building having no more than one story that has a total floor area of not more than 5,000 square feet and does not contain a clear span greater than 24 feet — a catch-all for one-story buildings in general.
The residential branch is (A) a private dwelling, and it carries no size limit at all.
Which matters, because planning around a threshold that does not govern your project is how a set of drawings gets to the city and comes back.
The profession the question is actually about
It was never the architect. It was the engineer.
Architects and engineers are licensed under two different chapters of Texas law, and they are not interchangeable. Your house is exempt from the first one. It is not exempt from the second. What pulls in an engineer is never the size of the house — it is whether the drawing touches something that holds the house up.
The engineering statute says the quiet part out loud. An engineer normally may not produce a complete building plan set without an architect — except for the buildings described by the exemption above, which is to say houses and duplexes. On your house, the engineer can carry the whole set. — Texas Occupations Code § 1001.0031(b)

If you are building in Fort Worth
The city is not subtle about it.
The answer is printed in the residential submittal packet, in the imperative, with no conditions attached.
“All new residential permits must have an engineered foundation plan.”
“Additions over 500 square feet, special designs, and post-tension plans require plans sealed by an engineer.”
“Lintels not from the City of Fort Worth tables and self-spanning veneer require engineering seals.”
City of Fort Worth, Submittal Requirements for New Residences and Additions, dated 02/05/2023 — the packet itself. Nowhere in it does the city ask for an architect’s seal on a single-family or duplex permit.
The honest other side
When an architect is worth the money.
Exempt does not mean unnecessary. The statute says you are permitted to skip the architect on a house; it says nothing about whether you should, and on some projects you very much should.
-
You do not yet know what you want built. An architect’s real product on a hard project is the exploration — testing options you would not have drawn for yourself. Paying a drafter to document a decision you have not made is the expensive way around.
-
The site is fighting you. A difficult lot, an awkward orientation, a house that has been added onto three times and never resolved.
-
An addition has to read as though it was always there. Inside one of Fort Worth’s designated historic districts — and only inside one — the city reviews how the work looks, not only whether it stands: “All exterior work requiring a building permit requires a Certificate of Appropriateness.” That is the city’s own historic design standards, Section 5. Outside a designated district it does not apply to you.
-
You want someone watching the build. Construction observation and contract administration are named in the statutory definition of practicing architecture, and on a complicated build they earn their keep.
What the exemption buys you is the right to make that a decision about value rather than a decision about permission.
Where we fit
We draw them. Then we have to build them.
Most people drawing residential plans never see what happens next. Our drafting team does — the same company frames the walls, so a drawing that is clever on paper and miserable on site comes back to us, not to you. That loop is the whole reason our sets read the way they do.
Drawings also travel in a way that crews do not. The drafting work is not bound by our construction radius — tell us up front which city the set is going to, because submittal requirements are the first thing we need to know and the last thing anybody wants to discover late.
Said plainly, because it matters
We do not stamp structural work. Engineering is partnered out — we coordinate with the engineer so the package reaches the city complete. A set of ours arrives with the sealed elements already sorted rather than flagged back to you three weeks in.
Sets run $2,000 to $16,000 depending on what is being drawn — the detail is on the floor plans page.

What the statute leaves people asking
The answers, with the section number attached.
Can a draftsman legally draw house plans in Texas? Texas Occupations Code § 1051.606(a)(4)(B)
Yes, for a single-family or duplex home. The Architects Act does not apply to a person preparing plans for “a single-family or dual-family dwelling or a building or appurtenance associated with the dwelling”, so long as that person does not represent that the person is an architect or architectural designer. The one thing the statute actually polices is the word: you may draw the house, you may not call yourself an architect while doing it.
What size house requires an architect in Texas? Texas Occupations Code § 1051.606(a)(4)(B)
None. There is no square-footage threshold and no story limit on the single-family exemption — a 12,000-square-foot custom home is exempt on exactly the same clause as a 1,200-square-foot one. The caps people quote are real but sit on different branches of the same sentence: multifamily is exempt up to two stories and 16 units per building, and commercial is exempt up to two stories or 20,000 square feet. Neither one governs a house.
Is it true that houses under 5,000 square feet don’t need an engineer? Texas Occupations Code § 1001.056(a)(2)
No, and it is the most repeated error on this topic. That figure belongs to branch (F) of the engineering exemption — a building having no more than one story that has a total floor area of not more than 5,000 square feet and does not contain a clear span greater than 24 feet — which is a generic one-story catch-all for buildings in general. The residential branch is (A) a private dwelling, and it carries no size limit whatsoever. What actually pulls an engineer onto a house is the work itself: structural systems and the specification of structural elements and connections, foundation design, evaluation, repair, or design changes to roof structural framing. Not the square footage.
Does Fort Worth require an engineer on a residential permit? Submittal Requirements for New Residences and Additions
For new construction, yes. The city’s own submittal packet is one sentence long about it: “All new residential permits must have an engineered foundation plan.” It also states that “Additions over 500 square feet, special designs, and post-tension plans require plans sealed by an engineer.” Nothing in that packet asks for an architect’s seal on a single-family or duplex permit — which is the whole point. The profession the city wants is the engineer, and only on specific elements.
Do you stamp the structural work yourselves? How we work
No. Engineering is partnered out — 6AH coordinates with engineers to get plans to the city — never an in-house structural stamp. We draw the set, we tell you up front which elements are going to need a seal, and we coordinate with the engineer so the package arrives at the city complete rather than coming back for a second round.
Statutes read 2026-09-23 at the Texas Legislature’s own site; Fort Worth requirements from the city’s published submittal packet. This is how the rules read, not legal advice about your project — and the city has the final say on any submittal.
Most of this is simpler than it has been made to sound
Tell us what you want to build. We’ll tell you what it needs.
Which clause your project sits on, which elements are going to need a seal, and what the set will cost — before you have spent anything finding out.
