Healthy-home design-build in Dripping Springs, Texas
Hays County · Hill Country flank · Climate zone 2A
Dripping Springs is the most current jurisdiction on our list, on the 2024 residential code by Ordinance 2025-O39 with the 2024 IECC and NEC 2023. Submittals are digital, and the city permits through MGO Connect.
This is Hill Country building: larger lots, wells and on-site septic in many locations, and Edwards contributing-zone and waterway rules that govern the site before the house. A current energy code plus a rural water supply is a specific combination — a tight shell and a private water source are two separate scopes, and we cost and verify them separately.

Climate-zone note
Dripping Springs 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 on the 2015-era map, with Hill Country exposure and larger, steeper sites.
- Edwards contributing zone and waterway protections that shape grading, drainage, and septic siting.
- Private wells and on-site sewage facilities are common, which makes water quality a project scope of its own rather than an assumption.
