Healthy-home design-build in Bulverde, Texas
Comal County · San Antonio metro · Climate zone 2A
Bulverde sits on the northern edge of the San Antonio metro where the suburbs meet the Hill Country. The city adopted the 2021 residential code by Ordinance 781 and NEC 2023 is confirmed, but the city's own web page still lists a much older code edition, and the energy code and permit portal are unresolved between those two sources.
We are not going to reconcile that discrepancy by guessing. Those rows are flagged pending verification until the building department confirms them by phone, and on a live project that call happens before design, not at submittal.

Climate-zone note
Bulverde 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; a mix of larger-lot and subdivision development.
- A live discrepancy between the published city page and the current ordinance — confirm before relying on either.
- City-run inspections, with the applicable energy code still to be confirmed.
