Peoria County, IL Building Safety: Electrical Permits (2026)

Section 12-22, in Article VI of Chapter 12, adopts NFPA 70, the National Electrical Code, 2017 Edition, by reference for the unincorporated county. The county's general cross-reference section, 12-10(d), confirms that any reference elsewhere in the adopted codes to the 'ICC Electrical Code' is to be read as this NFPA 70, 2017 Edition standard. Notably, the county's separate Building Code amendments in Section 12-15(ii) replace International Building Code Chapter 27 with language citing the National Electrical Code's 2020 Edition instead, so the two chapters of county code point to different vintages of the same national standard.

1 of the adopted Building Code, requires anyone who intends to erect, install, alter, remove, convert, or replace an electrical system to first apply to the building official and obtain a permit. This chapter, including the electrical code, applies only in the unincorporated areas of Peoria County under Section 12-1(a); incorporated cities enforce their own codes. The Department of Planning and Zoning, headed by the Director of Planning and Zoning, administers permits and inspections, and no permit issues until the fee set under Section 12-11 has been paid.
