If you use Permits Online, which I highly recommend, the basic permit is baked into the online forms. I'd recommend getting an account on PONL and starting the application now. For any owner/operator of the business (more than 10% interest I believe) you will need to do a separate OOI Application. Once the OOI Applications are submitted, you get a number(s) which gets plugged into the DSP Permit Application. You can start the applications now and see all the information and documents you will need and then compile it all and only submit when it is 100% done.
