Summary

Sec. 388.003. ADOPTION OF BUILDING ENERGY EFFICIENCY PERFORMANCE STANDARDS. (a) To achieve energy conservation in single-family residential construction, the energy efficiency chapter of the International Residential Code, as it existed on May 1, 2001, is adopted as the energy code in this state for single-family residential construction. On September 1, 2016, the energy efficiency chapter of the International Residential Code, as it existed on May 1, 2015, is adopted as the energy code in this state for single-family residential construction. On or after September 1, 2021, the State Energy Conservation Office may adopt and substitute for that energy code the latest published edition of the energy efficiency chapter of the International Residential Code.

Full Breakdown

Plano Building Inspections enforces the International Energy Conservation Code adopted under Chapter 6 of the city code, covering insulation, fenestration, duct sealing, lighting, and HVAC efficiency. Local amendments are coordinated with the North Central Texas Council of Governments to keep DFW-area requirements consistent. Unlike Austin or some California cities, Plano has not enacted a separate green building mandate or solar requirement, although Toyota and Legacy West projects voluntarily pursue LEED certification. Texas Local Government Code preempts certain energy disclosure mandates. Plano Sustainability and the Environmental Quality Commission promote voluntary energy efficiency programs and rebates through Oncor and CoServ.

Violations & Fines

Plano Building Inspections violation notices, permit denial, and required corrective work for IECC failures. Civil penalties up to 2000 dollars per day until compliance is achieved on commercial projects.

Frequently Asked Questions

Does Plano require solar panels on new homes?
No. Plano follows the IECC adopted under Chapter 6 but has not added a solar mandate. Texas state law also limits the local rules cities can impose on residential energy disclosures.
Where can I find Plano energy code amendments?
Plano Building Inspections publishes adopted code editions and local amendments. NCTCOG coordinates regional amendments with member cities to keep DFW requirements aligned.
