ADU Specials in Houston, TX
If you’re pricing an ADU or room addition in Houston, call (940) 242-3207 before you commit to anything. Sutton ADU Houston has offered written pricing and a 365-Day Done Right Promise since 2006, and when we run an offer, it’s meant to make an honest decision easier – not to rush you into one. The specials below are current through March 31, 2027, and they stack with the written-price guarantee we put on every single project.
Current Offers

Free Site Assessment & Written Price for Any Detached ADU
Every detached ADU project in Houston starts with a free site visit and a written line-item price before any work begins. You’ll see exactly what the structure costs, what site work runs, and where the money goes. No surprise invoices, no scope creep passed silently to the bill.
Valid through March 31, 2027. Mention this offer when you call (940) 242-3207.
Free Second Visit if Any Element of Your Build Fails
This one is written into the 365-Day Done Right Promise, but it’s worth calling out as a standing offer: if a repair or element of the build fails within a full year of completion, Sutton ADU Houston returns for a second visit at no charge. No haggling, no fee, no argument about whose fault it was.
Valid through March 31, 2027. Mention this offer when you call (940) 242-3207.
Prefab & Modular ADU Brand Consultation at No Cost
If you’re weighing an Abodu, Cover, Dvele, Mighty Buildings, Boxabl, or Plant Prefab unit against a stick-built addition, we’ll walk you through the trade-offs for your specific Houston lot at no charge. You get honest guidance on which product line fits your setbacks, your budget, and your timeline – not a sales pitch for whichever one we’d rather build.
Valid through March 31, 2027. Mention this offer when you call (940) 242-3207.
Complimentary Tuff Shed Conversion Assessment
Already have a Tuff Shed on the property and wondering if it can become a legal ADU in Houston? We’ll assess the structure, the foundation, and the permitting path and tell you straight whether it’s worth converting or if you’re better off starting fresh. Some sheds make great ADUs. Some don’t. We’ll tell you which one you have.
Valid through March 31, 2027. Mention this offer when you call (940) 242-3207.
First-Time Customer Courtesy: Photo-Badged Crew, Name Sent Before Arrival
For Houston homeowners who’ve never worked with Sutton ADU Houston before, here’s what you get on your first visit: the name and photo of the technician who’s coming, sent to you before they arrive. They show up in a clean, marked uniform and present a photo ID badge at the door. Every time. That’s the Threshold Standard, and it’s not optional.
Valid through March 31, 2027. Mention this offer when you call (940) 242-3207.
How to Redeem
Redeeming any of these offers is simple. Step one: call (940) 242-3207 and mention which offer applies to your project – a live person answers, every call, 24/7. Step two: we’ll book your free site visit and send you the name and photo of your technician before they arrive. Step three: the offer is applied at the time of service, in writing, on your line-item price. That’s it.
Why Sutton ADU Houston Runs Offers This Way

We don’t do seasonal gimmicks or countdown pressure. We’ve been building ADUs, home additions, and room additions in Houston since 2006, and we run specials for one reason: a homeowner who sees a written price before work starts is a homeowner who can make a real decision. The offers on this page are standing courtesies – free assessments, the free second visit, the written price – because those are the things that actually protect you when you’re spending five or six figures on a second home in your own backyard.
One thing we’ll say plainly: if you see an ADU price in Houston that sounds dramatically lower than $180,000 for a detached unit, ask what’s not included. In our experience, the number that’s too good to be true usually leaves out site work, utilities, permits, or the foundation. We’d rather give you the honest number up front and let you decide.
What the 365-Day Done Right Promise Actually Covers
The 365-Day Done Right Promise covers defects in workmanship for one full calendar year from project completion. If the work isn’t right within that year, Sutton ADU Houston makes it right. It’s a named, written guarantee stamped on every project – not a verbal assurance, not a handshake. And the free second visit is part of that same promise.
Common Questions About Sutton ADU Houston Specials

Do these offers apply to home additions and room additions, or just detached ADUs?
They apply to any project we take on, including home additions and room additions in Houston. The free written price, the free second visit, and the photo-badged crew standard are part of every Sutton ADU Houston project, regardless of size or type. Call (940) 242-3207 and tell us what you’re planning.
Can I combine multiple offers on one project?
Yes, within reason. The free site assessment, free second visit, and written price are standing practices on every project, so they don’t conflict with each other. If you have a specific question about combining offers on a Tuff Shed conversion or a prefab consultation, call (940) 242-3207 and ask directly – you’ll get a straight answer.
Do the specials expire on March 31, 2027?
Yes, the offers on this page are valid through March 31, 2027. But the 365-Day Done Right Promise and the written-price-before-work-starts policy don’t expire. Those are permanent parts of how Sutton ADU Houston operates in Houston, and they’ll be there whenever you’re ready to build.
Is the free second visit really free, or are there fees buried in the fine print?
It’s free. If an element of the build fails within a year of completion, we come back for a second visit at no charge. No haggling, no fee, no fine print. That’s the whole point of writing it into the guarantee.
Call (940) 242-3207 to schedule your free estimate, and mention any offer on this page. A live person answers, every time.
