A city built in one generation
Plano had 17,872 residents at the 1970 census, 128,713 by 1990 and 222,030 by 2000. Most of the houses standing today went up in those thirty years, so a typical Plano home is now somewhere between 25 and 55 years old. That's our inference from the census counts, not a survey of build dates.
A house that age has been through decades of wet springs and dry summers on clay, and it may have been repaired before. If you're buying, ask the seller for any earlier repair paperwork and whether a repair warranty transfers to you.
The ground
The Texas Water Development Board describes Houston Black clay, the state soil, as shrinking and swelling markedly with moisture, and places it in the Blackland Prairie running from north of Dallas to San Antonio. Soil changes from lot to lot, so look up your address on the USDA Web Soil Survey. Our signs and causes guide covers what that movement looks like inside a house.
Permits
Plano's Building Inspections "When Is a Permit Required?" sheet lists foundation repairs. The copy we found is marked revised 09/28/16 and doesn't list documents or an engineer requirement, so call 972-941-7140 to confirm. The Plano permit guide has the detail.
What repairs cost
We have no Plano-specific price survey. HomeGuide's national ranges run from $250 to $800 per crack to $10,000 to $20,000 for piers; see the cost guide. For context, a $15,000 repair is about 3% of Plano's median owner-occupied home value, by our arithmetic.
