Before you do anything, contact your local city, county or town business licensing department. Request information about starting a cart vending business. They should be able to provide you with licensing information as well as health related guidelines to which you must adhere.
This first step will save you a lot of time and frustration because you will know in advance what to expect. Depending on where you live, there may be a waiting list for these type licenses.
You should also look into getting a "resellers certificate." This will allow you to purchase stock and supplies without paying sales tax. Plus, the fact that most wholesalers will require this before they sell to you.
Once you get a green light with regards to licensing, you will need start up capital of approximately $1,500 to $3,000. Your biggest investment will most likely go to purchasing a two or three wheel hot dog cart.
A good used hot dog cart can be purchased for under $600, while the median price of a new hot dog cart is around $1,700. These prices will vary depending on your location.
There are two additional options when it comes to procuring your vending cart. The first would be to build your own and the second would be to rent your food cart.
