Lehigh County is highly decentralized, with nearly all building permits and zoning approvals handled by individual boroughs, townships, and cities. The county government primarily manages regional planning and specific environmental oversight, while local municipalities retain full jurisdiction over residential and commercial construction permits.
How this fits with the state
The state authority here is Pennsylvania Office of Attorney General; local building departments. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
