Permitting is split between the Hinds County Permit Department for unincorporated areas and individual municipal departments for incorporated cities like Jackson, Clinton, and Byram. The county maintains jurisdiction over unincorporated land, while municipalities manage their own zoning and building inspections. Development in flood-prone areas near the Pearl River requires additional review for compliance with local floodplain management ordinances.
How this fits with the state
The state authority here is Mississippi State Board of Contractors. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
