Summary
Unincorporated Arapahoe County ties every electrical permit to whichever edition of the applicable electrical code is in effect on the day the permit is applied for. LDC § 1-7.D requires all projects to comply with each applicable fire, plumbing, electrical, and mechanical code as currently adopted: overriding even projects built under an older, grandfathered land-use approval.
D. REQUIRED COMPLIANCE WITH GENERALLY APPLICABLE BUILDING CODES. All projects must comply with all regulations and codes that are general in nature and are applicable to all property subject to the jurisdiction of Arapahoe County, including the International Building Code, as adopted and amended by Arapahoe County; regulations, standards, and specifications adopted by the County to govern wastewater disposal, road and bridge construction; and each applicable fire, plumbing, electrical, and mechanical code, in effect on the date a permit is applied for pursuant to each of those codes.
Full Breakdown
LDC § 1-7 sets the County's transition rules for the Code's August 15, 2019 rewrite, including a general rule letting a building with a permit issued before that date finish under its original approval. ' In practice this means an electrical permit application is measured against whichever electrical code Arapahoe County has adopted and amended as of the date that specific permit is applied for, not the code in effect when an older land-use approval was granted. The LDC's Chapter 7 definitions describe the County's adopted construction standard generically as 'The Uniform Building Code of Arapahoe County,' but the Land Development Code text does not itself print the electrical code's edition year, amperage tables, or inspection schedule; those live in the separately adopted Building Code, outside the LDC's zoning and land-use chapters.
Electrical permit applications in the unincorporated County are processed, like building and fence permits, through the County's PWD Building Division. A; incorporated cities such as Aurora, Centennial, Littleton, and Englewood issue electrical permits under their own adopted codes.
Violations & Fines
LDC § 1-7.D makes compliance with the currently adopted electrical code mandatory for every permit application, regardless of any earlier, grandfathered land-use approval. Because § 1-4.B separately makes it unlawful to alter a structure without first obtaining a permit, unpermitted electrical work is enforceable under the County's Title 30 police powers (LDC § 1-2), which include the power to abate nuisances and to require correction before final inspection or occupancy.
