2024 Regional Model Construction Code Survey

Welcome to the web map of the 2024 Regional Model Construction Code Survey. Click through the headings above to see which versions of the International Codes have been adopted across the North Central Texas region as well as responses to other survey questions. Click on any city to see a summary of its responses.

The data on these maps were collected by the  North Central Texas Council of Government's   Environment & Development  department through an online survey. NCTCOG hosts the  Regional Codes Coordinating Committee (RCCC) , a committee composed of public and private sector code professionals with five code advisory boards that encourage the adoption of NCTCOG recommended model codes and regional amendments. The goal of the RCCC is to standardize the model codes used throughout North Central Texas.

According to the  State Energy Conservation Office (SECO) , "effective Nov. 1, 2016, SECO adopted the 2015 International Energy Conservation Code (IECC) for commercial, industrial and residential buildings taller than three stories. The code applies to R2, R3 and R4 residential buildings and excludes single and two-family residences of three stories or fewer above grade." For more information, click  here .  

According to the South-central Partnership for Energy Efficiency as a Resource,"Texas is a 'home rule' state which allows for local jurisdictions to make local amendments to the energy code, so long as the change does not result in a less stringent code. To amend the state code in  non-attainment and affected counties , Energy Systems Laboratory (ESL) of Texas A&M University must first determine whether the amended code is as stringent as the existing state code."  For more information, click  here .

In 2012, the US Environmental Protection Agency (EPA) designated ten counties (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant and Wise Counties) in North Central Texas as nonattainment for the pollutant ozone in accordance with the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). Nonattainment counties are defined as those that "do not meet (or that contribute to ambient air quality in a nearby area that does not meet) the national primary or secondary ambient air quality standard for a NAAQS" ( US Environmental Protection Agency ).

Affected counties are those designated as an "affected county" under the  Texas Health and Safety Code Chapter 386 - Texas Emissions Reduction Plan . In the North Central Texas region, the affected counties are Ellis, Hood, Hunt, Johnson, Kaufman, Parker, and Rockwall Counties.
