Tell us what you're seeing
Plano also has one of the most detailed permit processes in the region. One detail catches a lot of people out: Plano turns away drawings marked "not for construction" or "for pricing only." So the sketch your contractor hands you with the quote won't get through plan review.
Why Foundations Move in Plano
Soil scientists measure how much a soil swells with a number called linear extensibility. It's the percent a soil grows or shrinks as it gets wetter or drier. Under 3 is low. Over 9 is very high.
Houston Black covers roughly 64% of Plano and reads 17, with 55% clay from the surface down. No other city we serve has that much of its ground on one soil at that reading. Garland and Mesquite share the 17 figure, but over a smaller share of their ground.
In practical terms, close to two thirds of Plano addresses sit on clay near the top of the national range. It swells and shrinks a lot as the weather swings from a wet spring to a dry August.
The Eddy pocket is the exception
About 16% of Plano sits on Eddy, and Eddy reads 1.5. That's low reactivity, around 32% clay, and it drains well.
So Plano holds both ends of the scale. Garland is the only other city we cover with the same spread. One address can be on ground that barely moves, while another a few streets away sits on the most reactive clay we measured.
If your house is on Eddy and it's still moving, shrink and swell probably isn't the cause. A plumbing leak, grading that sends water toward the slab, or roof water landing in one spot are the usual suspects. Ruling those out is what a foundation inspection does first.
Austin, Burleson, Altoga and Frio fill the remaining 20%, reading between 4.5 and 8.
What Plano Homes Are Built On
Plano is large. Census figures count 116,440 housing units, the most of any city we serve, with a median build year of 1993.
The build years are spread wide: about 14.2% from the 1970s, 22.4% from the 1980s, 29.4% from the 1990s, 16.7% from the 2000s and 11.4% from the 2010s. Only 1.4% were built before 1960.
That makes pier and beam rare, but the slab type still varies a lot with the age of the neighborhood. A 1970s or 1980s Plano house is most likely a conventional slab with rebar. A house from the 1990s or later may well be post-tension, with steel cables pulled tight inside the concrete.
Those cables should never be cut or drilled into blind, so it's worth finding the builder paperwork before any work starts.

Permits for Foundation Repair in Plano
Plano runs a full plan review on foundation repair, not a simple permit over the counter. The city publishes its requirements on its own form.
Here's what the city asks for:
- Two copies of completed construction documents, with a completed permit application
- Foundation plans showing the pier or footing locations
- Complete pier or footing details
- An engineer's letter
- Every drawing and document dated, sealed and signed by a State of Texas registered engineer
- The property's legal description on each document
- A reference to the applicable building code on all drawings
Two points in that list are easy to miss. Drawings labeled "not for construction" or "for pricing only" are rejected. And the plan review fee is non-refundable, so a rejected submittal costs money as well as time.
Before anything goes in, ask your contractor whether the engineer's drawings will be issued for construction. It's a short question that can save you a resubmission.
Building Inspections is at 1520 Avenue K, Suite 140, and you can reach them at 972-941-7140.

Plano Foundation Repair Questions
Is Plano really worse than the cities around it?
On soil, yes. About 64% of Plano sits on Houston Black reading 17, the highest reading in our survey. Richardson next door is 36% Houston Black, with another 44% on Austin at 7.5. It's the same region with very different odds.
My contractor gave me drawings with the quote. Can we submit those?
Probably not. Plano turns away drawings marked "not for construction" or "for pricing only." The engineer has to issue a sealed set for construction, and the plan review fee isn't refunded if the submittal comes back.
Why does every document need the legal description?
The city requires the property's legal description on each document, so the submittal can't be matched to the wrong address. Your title paperwork or the county appraisal record will have it.
What if my house is on the Eddy soil?
About 16% of Plano sits on Eddy, which reads 1.5 and hardly moves. If your house is on it and the floors are still going out of level, a leak or a drainage fault is a more likely cause than the clay.
Does my Plano house have a post-tension slab?
It depends on the build year, and Plano's homes span several decades. Houses from the 1990s onward are the likelier candidates, and that's 58.8% of the city. It's worth confirming before anyone drills.
