The one-page sheet
Open the City of Schertz’s residential foundation repair requirements and the first line is blunt: a building permit required for foundation repair, and that covers warranty work. That detail matters. A contractor returning to adjust piers under a warranty still needs to go through the city.
The sheet’s submittal list asks for:
- A building permit application.
- An engineered plan showing pier placement.
- A floodplain permit application, if the property is in a floodplain.
- After the work, a sealed engineer letter after repair.
Inspections follow the same pattern. The city lists new pier inspection and foundation final, and says plumbing and electrical repairs may require additional permitting. Inspection requests received by 6:00 a.m. are inspected the same business day.
A city in three counties
The Handbook of Texas lists Schertz as belonging to Guadalupe, Comal and Bexar counties, which means county soil descriptions only partly apply to a given lot. Guadalupe County’s entry says its soils vary dark, calcareous clay to fine, sandy loam, with the Blackland Prairie in the northwest. Next door in Bexar County, the middle strip is Blackland Prairie with Houston Black clay.
Translation: a Schertz lot can be on dark calcareous clay, on sandier soil, or on something between. An inspection should look at the lot rather than the zip code.

Houses built since the 1990s
The Census Bureau puts the median Schertz home’s construction year at 2002. Only 17% of its 16,573 housing units predate 1980, and 55% date from 2000 or later. The city is mostly detached houses: 86%, a higher share than San Antonio’s 59%.
That mix means slabs, built in subdivisions, with the usual drivers: clay under the slab, downspouts and grading that move water to one side, and tree roots.
Water: Carrizo, not Edwards
San Antonio and New Braunfels draw on the Edwards Aquifer and follow its stages. Schertz is different. The City of Schertz says it has received its water from the Carrizo Aquifer. Its standing conservation plan bans sprinkler watering 10 a.m. to 8 p.m. every day, and allows a handheld hose, other handheld device or drip irrigation at any time. The city warns that restrictions could follow if dry conditions continue.
For foundations, that means hand-watering and drip lines are not limited by day. It doesn’t mean unlimited: the watering guide explains why more isn’t better.

Before you sign in Schertz
- Ask who pulls the permit and who supplies the pier plan and the sealed letter.
- Ask whether the quote includes the city inspections.
- Keep the sealed letter. A buyer will ask for it.
- If the property is in a mapped floodplain, ask about the floodplain permit the sheet mentions.
