Chesapeake is an independent city, meaning it functions as both the county and municipal authority for all permitting and zoning. There are no separate incorporated towns within the city limits, so all development review is centralized under the city government. The city maintains specific overlays for the Chesapeake Bay Preservation Act and various flood hazard zones.
How this fits with the state
The state authority here is Virginia DPOR - Board for Contractors. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
