Stafford is the town where the maps seem to disagree. On the state geologic map, 12 of our 25 sample spots landed on ground the USGS labels "areas predominantly sand." Yet in the USDA soil survey, 20 of those same 25 spots came up high or very high for shrink and swell. If you've found a crack, you're weighing foundation repair in Stafford and you've heard the town sits on sand, that's the first thing worth clearing up.
The short version: the "sand" on the rock map describes old stream ridges deep in the ground's history. The soil a Stafford slab actually rests on is mostly clay that swells when it's wet and shrinks as it dries. Below, each section takes one public record and says what it means for your house.

The Ground Under Stafford
We sampled the USGS state geologic map and the USDA soil survey at 25 spots across Stafford. The rock map split them this way: 12 on the Beaumont Formation's sandy ridges, 8 on its clay, and 5 on river deposits. The USGS describes those ridges as old stream channels and levee ridges, standing 1 to 2 meters (about 3 to 6½ feet) above the clay around them.
The soil survey tells you what's on top. Here's how Stafford's 25 spots split:
- 12 very high. Lake Charles clay covers 10 of them. It reads 12.4 at the surface and peaks at 13.6 from about a foot down. Brazoria clay, the river bottom's strongest soil, covers the other 2 and reads 17.
- 8 high. Bernard reads 7.3 from about 6 inches down, Edna 6.6 a little deeper, and Belk clay 7.5.
- 5 moderate or low. Norwood loam covers 2. The other 3 fall on one Bernard map unit whose survey reading doesn't match its 30% to 52% clay. We counted those as low anyway, so 20 of 25 is, if anything, an undercount.
The USDA rates 9 or more very high and 6 to 9 high. So most Stafford slabs sit on clay that moves with the weather, sandy rock map or not.
The USDA also says water enters Lake Charles clay quickly when it's dry and cracked, and very slowly once it's wet. After a dry summer, a heavy rain can run down those cracks right beside a slab. Gutters that empty well away from the house help, and so does a yard that slopes away. The ASCE Texas guidelines put the minimum at a 6-inch drop across the first 10 feet.
To see which soil is under your own lot, search your address on the USDA's free Web Soil Survey. Our soil guide explains what each name on that map means.
Flood Zones in Stafford
We checked FEMA's flood map at the same spots. Of the 24 that returned a result, 2 fell inside the 1% annual chance floodplain. Another 3 sit in FEMA's moderate zone, between the 1% and 0.2% floods, and 3 more in an area FEMA labels as having reduced flood risk due to a levee. The other 16 landed in the area of minimal flood hazard.
That's a lighter flood picture than Sugar Land's, where 6 of 24 spots fell in the floodplain. FEMA's own advice still holds, though: there's no such thing as a no-risk zone, and your address is the one to check. Stafford's code requires a development permit before building or development starts in a special flood hazard area. For a walk-through of FEMA's map, see the flood zones guide.
Stafford Homes by Decade
The Census counts 6,988 homes in Stafford, and the median one was built in 1992. Building was spread out more evenly than in Sugar Land, where one decade stands out:
- Before 1960: 3.0%
- 1960s: 2.5%
- 1970s: 16.3%
- 1980s: 22.5%
- 1990s: 25.3%
- 2000s: 17.5%
- 2010s: 11.5%
- 2020 or later: 1.3%
So about 4 in 10 Stafford homes went up from 1960 through 1989, and a little over half came after. Census figures stop at the build year. They say nothing about the foundation itself.
Across Texas, though, homes from these decades are more likely to sit on concrete slabs than on piers. A 1970s Stafford slab went in before 1980, the year the Post-Tensioning Institute set out its method for house slabs on swelling soil. To learn which kind is under your floors, book a foundation inspection.

Permits and Rules in Stafford
Stafford issues permits for this work. The city's own monthly permit reports list residential permits with the type "Foundation Repair." Here's what else the city's pages say:
- Apply online. Since May 2023, Stafford's Development Services takes permit submittals only through its online portal, MGO Connect. No email or paper copies.
- Inspections at each stage. A permit isn't finished until every required inspection is done. Permits run 180 days and expire if work doesn't start within six months.
- An older code. Stafford still builds to the 2015 International Residential Code. Sugar Land moved to the 2024 codes in January 2026.
- No named fee. Stafford's 2026-27 schedule prices repairs in general but never names foundation work. It does list a $150 registration for contractors the state doesn't regulate, but it doesn't say whether that covers foundation companies.
With no state license for foundation repair companies in Texas, Stafford's permit and inspections do the checking. Before work starts, ask the Permit Technician at 281-261-3926 how a foundation repair is priced, whether the company must register and whether an engineer's letter is needed. Rules for the towns nearby are in our permits guide.

Stafford Questions
Is Stafford built on sand?
Mostly not, where it counts. The rock map marks 12 of our 25 spots as sandy ridges, but the soil survey put 20 of the 25 on high or very high clay. The soil is what a slab rests on.
Will I need a city permit for Stafford foundation work?
Yes. Stafford's monthly permit reports list "Foundation Repair" permits, and the city takes applications only through MGO Connect.
Which building code does Stafford use?
The 2015 International Residential Code, adopted in 2018. A contractor used to working in Sugar Land, which adopted the 2024 codes in January 2026, may find some details differ.
Is my Stafford house in a flood zone?
Most of our Stafford spots weren't: 2 of 24 fell in the 1% floodplain. Before deciding anything, pull up your address on FEMA's Flood Map Service Center.
