Shed Placement & Setbacks

Don’t choose the shed location until you’ve checked your setbacks.

  • Cannot be placed in the front yard.
  • Must remain outside required setback areas.
  • Must meet required distances from property lines.
  • Cannot be built before the primary structure on the property.

Watch for Drainage Easements & Swales

This is especially important before installing a shed.

Hamilton County specifically says sheds should not be built in backyard drainage swales, because they can block drainage.

Regulated-drain easements may also require additional approval.
