Draw site plan to scale, not less than 1-inch=100-feet, show all property corners, existing and proposed structures, adjacent roads, all storage tank locations, all easements, utility locations, and north arrow.

Placement of a modular home on a lot that has never been built on before will require a Site Development Permit. Replacing an existing modular home does not typically require a Site Development Permit.

The permit application fee covers the cost of review and inspection.
