Providence County does not exercise land-use or building permit authority; all permitting is handled by the individual cities and towns within the county. Municipalities manage their own zoning, building inspections, and environmental overlays, including local floodplains and historic district requirements.
How this fits with the state
The state authority here is Rhode Island Contractors' Registration and Licensing Board. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
