Why Foundations Move in Richardson
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.
Richardson is split between two very different soils.
Austin covers about 44% of the city and reads 7.5, with 45% clay and good drainage. That's high, but it's well short of the most reactive clay in the region.
Houston Black covers about 36% and reads 17, with 55% clay from the surface down. That's the highest reading in our survey, the same one we get in Garland and Plano.
Dalco and Lewisville add another 12% between them, both at 7.5. Stephen, on a small slice of the city, reads 4.5.
What that split means for you
More of Richardson sits on calmer ground than most people assume. A little over four in ten addresses are on Austin, which moves less than half as much as Houston Black for the same swing in moisture.
That's not a promise about your house, though. The two soils sit side by side across the city, and the only way to know which one you're on is to check your address.
It does explain why foundation trouble in Richardson is often patchy. One street sees repeated problems, while the next street over sees almost none.
The City's Own Watering Advice
Richardson publishes homeowner guidance alongside its permit page. It's worth following, because it comes from the people who inspect this work.
- Water evenly on all sides of the house, so the soil moisture stays even
- Keep drainage moving away from the foundation, and stop water pooling against it
- Let downspouts discharge at least three feet from the foundation
- Keep an eye on trees or large shrubs within 20 feet of the house. Their roots pull moisture out unevenly, and that ground may need extra water in a dry spell
Even moisture is what matters most. A foundation rarely fails because the soil is wet or dry. It fails because one part is wet while another part is dry. Where watering alone isn't enough, foundation drainage work takes it further.
What Richardson Homes Are Built On
Census figures count 47,827 housing units in Richardson, with a median build year of 1985. About 20.8% went up in the 1970s and another 16.3% in the 1960s. In all, 48.5% of the city dates from 1960 to 1989.
Around 7.2% were built before 1960. That's a bigger share of older homes than the newer suburbs to the north and east have.
So Richardson has a real mix. A pre-1960 house may be pier and beam with a crawl space. A 1960s or 1970s house is very likely a conventional slab with rebar. Newer homes, including the 18% built in the 2010s, may well be post-tension, with steel cables inside the concrete that should never be drilled blind.
Your builder paperwork is the first place to check. If it's gone, a foundation inspection will settle it.

Permits for Foundation Repair in Richardson
The trigger is a pier count, not a dollar figure. If your job uses four or more piers, you need a permit.
Here's what the city asks for:
- A completed residential building permit application
- An outline drawing of the structure showing the proposed repair areas
- A report of the items to be corrected and the repair details, signed and sealed by a Texas licensed engineer
Two more conditions are easy to miss. The permit has to be approved and posted at the property before any work starts. And every contractor has to be registered to work in the City of Richardson before they can pull it.
Applications go to permits@cor.gov or 2360 Campbell Creek Blvd, Suite 550. You
can reach Building Inspection at 972-744-4164 or 972-744-4180.

Richardson Foundation Repair Questions
Can I avoid a permit by using three piers instead of four?
The rule starts at four piers, so a three-pier job falls below it and needs no permit. But the pier count should follow what your house needs, not the permit threshold. An engineer specifying three piers on a house that needs six is a much bigger problem than a permit fee.
Does my contractor need to be registered with Richardson?
Yes. The city requires every contractor to be registered before they can work in Richardson. It's fair to ask to see it before you sign anything.
Is Richardson soil as bad as Garland's?
In part. About 36% of Richardson sits on Houston Black at 17, the same as Garland. Another 44% sits on Austin at 7.5, which is much calmer ground. Your address decides which one applies to you.
How far should my downspouts discharge?
The city says at least three feet from the foundation. Downspout extensions don't cost much, and they're one of the easiest fixes you can make yourself.
Why does the permit have to be posted at the property?
Richardson requires the approved permit to be posted on site before work starts, so an inspector passing by can see the job is approved. Your contractor should handle it, but it's worth checking that it's up.
