Healthy-home design-build in Wimberley, Texas
Hays County · Hill Country flank · Climate zone 2A
Wimberley requires permits for all new construction, but the city has no online permit portal — filings go through City Hall. The Blanco River floodplain is the defining constraint on a large share of the buildable land here, and the 2015 flood is still the reference point for how the river behaves.
The adopted code editions are not resolved in the public record we hold, so they carry a pending-verification flag rather than a stated edition. We confirm with the city directly before committing a design.

Climate-zone note
Wimberley 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 with Hill Country siting; floodplain review governs a significant portion of parcels.
- No online portal — the permit path is in person and needs to be scheduled into the programme.
- Wells and on-site septic are common, so water quality and drainage are early design questions.
