The Building Inspection Division issues permits for unincorporated Weld County under the adopted 2024 International Codes and Weld County Code Chapter 29 contains an exempted-work list, but the County's specific fence exemption line could not be confirmed from primary sources; confirm the fence rule with the Building Inspection Division.
