Abodu Construction in Irving, CA | Rowan Construction Group
We provide independent Abodu construction service across Irving, from Valley Ranch to North Irving. Most calls start with the same question: will this modular unit hold up on Blackland Prairie clay? The short answer is yes, but only if the foundation work is done right the first time. That is the part of the job out-of-area contractors get wrong here. Call (470) 298-9650 for a written estimate before you buy or build.
At Abodu sales & service, we handle site preparation, foundation work, assembly, and post-installation repairs on Abodu One, Two, and Studio units. We are not an authorized Abodu dealer and we do not claim factory training. What we have is 18 years of structural remodeling experience under Grant Rowan, including modular ADU installations on some of the most unforgiving soil in North Texas.
Why Irving Residents Choose Us for Abodu Service
Abodu units arrive on a truck. The factory does a good job. The local part – the part nobody at the factory can control – is what happens when that unit meets Irving’s expansive clay, unlike Abodu in Dallas where loam soil behaves very differently. We have watched clay heave rack an Abodu One door frame six weeks after install because the original pier depth was spec’d for Dallas loam, not montmorillonite. That is the gap we fill.
Grant Rowan trained in construction technology at Los Angeles Trade-Technical College – framing, concrete, and estimating, before he ever ran a paying job. He has spent the better part of two decades on structural remodels where walls come down and load paths get recalculated. In Irving, that background matters more than any factory certification. We understand pier depth, drainage grading, and what frost-free footings mean on a 1960s slab in North Irving. And we put every number in writing before anyone picks up a tool.
Common Abodu Construction Problems We Solve in Irving

- Foundation settling and module racking. Blackland Prairie clay shrinks in summer drought and swells after spring rains. An Abodu unit set on piers too shallow for Irving’s soil will shift. Doors stop latching. Stress cracks open at module joints. We re-level the unit and install correctly spec’d piers to stop the movement.
- Water intrusion at roof-to-module intersections. Abodu’s flat and low-slope roof designs are vulnerable at the roof-to-wall transition, especially after the hard spring rains Irving gets. We reseal with high-movement elastomeric flashing that flexes with module shifts instead of tearing.
- HVAC duct leakage at module seams. Transport and crane work can open air gaps at the module junction. In a Texas August, that means a unit that never cools. We inspect the seam, seal the ductwork, and verify static pressure before calling the job done.
- Improper site anchoring on sloped or expansive lots. Valley Ranch lots usually drain fine. Older North Irving slabs can pitch in unexpected directions. If the anchor spec ignored the actual grade, you get deck separation and uneven steps. We re-anchor and correct the transition.
- Door frame racking from clay heave. This shows up as a front or interior door that binds at the top corner. It is rarely the door – it is the unit settling unevenly. We diagnose the actual cause before touching the hinge.

AfterAbodu Service in Irving: What Local Conditions Mean for Your Equipment
Irving’s Las Colinas Urban Center is not just an office district. It comes with an engineering overlay that affects how modular ADUs are permitted and built. Setback rules and impervious cover limits in Las Colinas differ measurably from what Abodu in Garland or Grand Prairie allows a mile west. More importantly, the overlay requires deeper pier depths through Blackland Prairie clay than what a standard site-prep contractor might assume. A crew that does not know Irving will hand you a pier schedule based on generic Texas soil data. That schedule will be wrong. We have seen the result: a re-level job on a one-year-old Abodu One in Las Colinas that should never have moved. At a North Irving property near Story Road, our crew set an Abodu One on a 1950s slab lot with severe clay heave. We installed 12-foot helical piers through the original slab, re-leveled the unit after transport, and resealed the roof-to-wall transition with a high-movement elastomeric flashing system, eliminating the racked door and water staining the owner had been fighting after winter rains. The lesson is not subtle: in Irving, the foundation is the unit.
Abodu Models & Products We Service in Irving

We work on all three current Abodu lines: the Abodu Studio for compact single-room ADUs, the Abodu One for single-story units, and the Abodu Two for multi-room layouts. For structural connections and weatherproofing components, we use OEM-specified parts when public suppliers carry them. For fasteners, sealants, and finish materials where clay-soil movement is the deciding factor, we install certified aftermarket components that outlast factory parts in Irving conditions. We keep the most common module-joint sealants, flashing profiles, and pier hardware stocked locally so we do not lose a week waiting on a distributor. On isolated module-joint or roof issues, we recommend repair over replacement. Full unit replacement only makes sense when structural integrity has failed across multiple modules – which, honestly, we have seen twice in 18 years, both on units built by others.
Abodu Service Pricing in Irving

| Abodu Site Prep & Grading | $8,000 - $20,000 |
| Module Joint Weatherproofing | $1,200 - $4,000 |
What drives the foundation number is actual pier depth – we have seen clay in North Irving require 12-foot helical piers where an 8-foot schedule would pass in Carrollton. A free estimate from us includes a site walk, a look at the existing slab or lot grade, and a written scope with these line items called out, including any Fence Installation - Irving coordination if your project needs perimeter work. Call (470) 298-9650 to schedule it.

FAQs - Abodu Construction in Irving
In most of Irving, yes – the expansive clay demands deeper piers and more careful grading than a standard modular install. Foundation and pier installation runs $15,000 to $35,000 depending on depth and slab condition. Call (470) 298-9650 for an exact number on your lot.
Almost always. We remove the failed sealant, inspect the underlying flashing, and install a high-movement elastomeric system that flexes with the module instead of cracking. Repair over replacement unless the structural integrity of the roof has failed.
Plan on six to ten weeks from first excavation to final utility tie-in, with Irving’s permit review and Las Colinas engineering overlay adding time on certain lots. We give you a written schedule at contract.
If you are connecting structurally, no. The City of Irving will require an assessment of the existing slab, and on older 1950s-1970s ranch homes in North Irving, that assessment often turns up heave damage that must be addressed first. We handle both sides of that equation.
Yes. Drainage engineering matters as much as pier depth here. We grade and direct water away from the unit before it becomes a problem, and we work within Irving’s drainage and floodplain review process, along with our Driveway & Pavers in Irving team when site hardscaping affects runoff. Call (470) 298-9650 for specifics on your site.
