Zoning Building Codes

Adopted Building Codes & Technical Standards

Welcome to the Cass County Building Codes reference page. To ensure all structural, mechanical, electrical, and plumbing work meets rigorous safety and efficiency standards, Cass County officially adopts and enforces uniform building codes. The links below detail our current regulatory standards, including the International Code Council (ICC) frameworks for residential and commercial construction, the National Electrical Code (NEC) for electrical installations, and the International Energy Conservation Code (IECC) for energy efficiency. These uniform technical codes serve as the mandatory guidelines for all architects, engineers, contractors, and property owners designing or renovating structures in our jurisdiction. Adhering strictly to these updated standards protects life safety, enhances building durability, and guarantees your project will successfully pass our required field inspections.

Important Note on Electrical & Inspection Frameworks: While Cass County reviews and administers local structural, plumbing, and mechanical codes, please note that all electrical permits and electrical inspections are provided directly by the Nebraska State Electrical Division. Additionally, builders should cross-reference these codes with the Cass County Zoning Regulations to confirm proper property setbacks, height limits, and lot coverage requirements before final plan submission.
