Healthy-home design-build in Cibolo, Texas
Guadalupe County · San Antonio metro · Climate zone 2A
Cibolo runs on the 2021 residential code with the 2021 IECC and NEC 2023 under Ordinance 1475, permitted through MGO Connect. The city publishes its adopted codes and amendments plainly, which makes the permit path here one of the more predictable in the metro.
The stock is overwhelmingly newer subdivision housing. Our work here usually starts with measurement — envelope leakage, duct leakage, and ventilation rates — because the assemblies are recent enough that the question is how well they were executed, not what they were built to.

Climate-zone note
Cibolo sits in climate zone 2A on the 2015-era map — hot and humid. For most of the year the moisture drive runs from outside toward the interior, which is the opposite of the cold-climate assumption most published detailing is written around. That single fact governs where the vapour control belongs, how a wall is expected to dry, and why an interior polyethylene layer is the wrong answer here.
The 2021-era zone designation for this jurisdiction is not settled in our record and carries a Pending Verification flag. It does not change how we detail an assembly, but it can change which code table applies, so we confirm it before submittal rather than assume it.
What we run into here
- Climate zone 2A; the dominant failure mode in newer stock is mechanical rather than structural.
- Clear published code adoptions and amendments, so scope assumptions can be checked in advance.
- City-run inspections through a single portal.
