Franklin County is the biggest, most fragmented permit map we work in: Columbus proper plus dozens of separate cities, villages and townships, each with its own zoning desk. We confirm which one your address actually uses before we file anything, and our realistic reach from the Johnstown shop is strongest on the east and northeast side of the county.
Typical permit fees for a residential deck in Columbus run $100 to $350 depending on size, though fees and forms change and we confirm current requirements before we file. The frost line is the same 32 inch statewide minimum used everywhere else in Ohio, not a Columbus-specific number: we still pour to 42.

Franklin County is a different kind of service area than our Licking County towns: not one small permit desk but a patchwork of dozens, inside a metro of over a million people. That changes how we approach a Columbus-area job more than the framing itself does.
