The City of Aurora (in conjunction with the State of Colorado) has transitioned to the requirements of the 2026 National Electrical Code (NFPA 70) (effective 8-1-2026).
Any new applications for permit of electrical work will be reviewed and inspected to the 2026 NEC requirements.
Any permits pulled from existing single-family master plans will automatically be processed under the 2026 NEC.
Any multifamily master plans will need to submit revisions to show compliance with the 2026 NEC before further permits are pulled.
