Austin

Local adoption Austin adopted 2024 IWUIC. This is the rule.

Sourced local code city in Texas · last verified 2026-08-26

Austin is a sourced city record in Texas. The construction answer is the application of Austin 2024 IWUIC proximity-zone application, adopted 2025-04-10, effective 2025-07-10. A ZIP is a postal lead, not a parcel.

What is established here

Austin's amended 2024 IWUIC uses Proximity Zones A, B, and C in full-purpose and limited-purpose City areas. The official map starts the review; onsite measurements and the code official determine local reach.

What we do not have

These checks stay open because the sourced instrument leaves them to the official record, not because this page skipped them:

Whether the instrument is in force for this project's date.
The official boundary that would put a parcel inside the application.
Confirmation from the building official for this project.
The official hazard or WUI map for the lot.
Whether this project type is in scope of the instrument.
