Six climate zones from the Gulf to the Panhandle
Texas counties are spread over six IECC zones. DOE's county guide, PNNL-33270 (2021 county data), assigns Texas counties to six IECC zones: 2A in 81 counties, 3B in 70, 3A in 58, 4B in 28, 2B in 14 and 1A in 3. DOE uses A for moist and B for dry, and Texas has counties in both groups.
Window ratings split as well. Texas crosses more than one zone on the ENERGY STAR climate zone map (August 2025). The official ENERGY STAR zone finder returns the zone for a single ZIP code, which suits a buyer that covers, for example, both Houston and El Paso.
Coastal inspections and contractor rules in Texas
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
The Texas Department of Insurance sets a building standard for part of the coast. Its page on windstorm inspections (checked October 7, 2026) says properties in 14 coastal counties and in parts of Harris County east of Highway 146 are in a designated catastrophe area, and that most homes need a certificate of compliance to buy a Texas Windstorm Insurance Association policy. TDI states that most new construction, roof replacements, major repairs and other alterations require an inspection, and its list of examples that do not includes replacement of glass in windows or doors.
Texas has no state registration for home builders today. A 2011 House bill analysis records that the Residential Construction Commission ceased to exist on September 1, 2009. The trade licenses the state does issue are described on leads in Texas.
Texas residential energy code status
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
The DOE Building Energy Codes Program page for Texas (checked October 7, 2026) lists the 2015 IECC with amendments as the state residential code, adopted June 14, 2015 and effective September 1, 2016. DOE names the State Energy Conservation Office as the adoption contact. Commercial buildings are listed under the 2015 IECC and ASHRAE 90.1-2013.
Newer housing, with older pockets
Texas housing is recent by the Census Bureau's count. The median year built is 1992 in table B25035 (ACS 5-year 2020-2024), and table B25034 (ACS 5-year 2020-2024) places 33.2% of units before 1980. The same table counts 2,167,391 units from 2000 to 2009 and 2,114,874 from 2010 to 2019.
Owner-occupied Texas homes have a median value of $283,800 in table B25077 (ACS 5-year 2020-2024).
How Texas window campaigns are filtered
- ZIP code: the main control in a state with six IECC zones and a coastal inspection area.
- Number of windows and scope: glass-only work versus full window replacement, which matters inside the windstorm area.
- Home age: separates the large post-2000 stock from older neighborhoods.
- Homeowner status: the owner is the party who signs and who holds the insurance policy.
