Texas energy code guide

What Texas builders and homeowners need to know about energy code compliance and load calculations for residential permits.

DRAFT — outline published; full guide body in progress.

Texas energy code enforcement varies significantly by jurisdiction — the state does not have a single statewide mandatory residential energy code adopted the way some states do, so what your building department requires depends heavily on your specific city or county.

What this guide will cover

  1. Which IECC edition (if any) your city or county has adopted
  2. Texas climate zones and what they mean for Manual J design temperatures
  3. Common compliance paths used across major Texas metros (Houston, Dallas-Fort Worth, Austin, San Antonio)
  4. Whether a Manual J is required for HVAC permits in your specific jurisdiction
  5. What to confirm with your local building department before ordering a report
