Summary

Frisco adopts the International Energy Conservation Code through FMC Chapter 14, with local amendments. Builders must meet insulation, window, and HVAC efficiency targets, and Frisco offers limited incentives but does not mandate full LEED-style green certification on private projects.

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

FMC Chapter 14 adopts the International Energy Conservation Code along with the broader I-Code family, setting minimum insulation, window U-values, duct sealing, and HVAC efficiency for new homes and commercial buildings. Texas state law constrains cities from banning specific fuel types like natural gas, so Frisco enforces performance-based energy targets rather than electrification mandates. Builders may pursue voluntary green-building certifications like LEED, NGBS, or Energy Star, sometimes encouraged through plan-review fast tracks. Solar-ready and EV-ready provisions appear in newer code cycles. Existing buildings face energy upgrades primarily at major renovation triggers, not as standalone retrofits.

Violations & Fines

Failed blower-door tests, missing insulation reports, or non-compliant HVAC equipment block certificate of occupancy and may force rework, re-inspection fees, and new energy-rater verification visits.

Frequently Asked Questions

Does Frisco require new homes to be all-electric?
No. Texas state preemption blocks Frisco from banning natural gas connections. The city enforces energy-performance targets but lets builders choose fuel types within those limits.
Are existing Frisco homes forced to retrofit insulation?
Generally no. Energy upgrades typically apply at major renovation, addition, or system-replacement triggers, not as standalone mandatory retrofits on existing single-family homes.
