About Us

Thank You for Visiting the Jefferson County Planning & Zoning Website

The unincorporated area of Jefferson County is zoned and building permits are required. The County adopted zoning in the late 1960's and the current Zoning and Subdivision Regulations were adopted in March of 2009. The County participates in the National Flood Insurance Program.

The public is encouraged to phone or email the Planning and Zoning office to inquire about the process for obtaining a building permit. Verification can be made regarding a parcel's eligibility for a building permit. The parcel can be checked for zoning compliance and potential floodplain areas.
