Do I need a permit to replace a hood vent with OTS microwave?

I purchased an over the stove microwave/vent to replace my regular vent. Delivery people were unable to install the microwave because the hood is hard wired. Do I need to get a permit to change the electrical before I hire someone to do it and install the microwave?

No, not at all. Your hooking up to existing wiring with any needed modifications.
Not in Florida, but you would have to check with local authorities.
75% of home repairs and additions are not permitted
You may not need a permit, but you still need to do it the right way according to building and electric codes. If your new unit is a plug in type. where are you going to plug it in? Is there an upper cabinet unit above the microwave? if so, you can put an outlet inside the cabinet using the wires from the old unit. Electric code requires a dedicated 20amp circuit with 12-2 wire for an OTR microwave with a fan. You cannot just plug it into any old outlet near it. Also, your existing ductwork may not line up with the microwave, so be prepared to modify the ductwork to make the proper connection.
You shouldn't need a permit but you do need to be comfortable with hard-wiring the microwave to tie in with the circuit. Best to have a licensed electrician do the work so it is completed up to the current code.
Building codes vary from location to location call you local planning department.
