My partner and I are starting an advertising business distributing doorhangers throughout various cities. I was wondering if there are any permits needed for this certain field. I am new to small-business and would appreciate ANY feedback or shared knowledge.

Welcome aboard!

I would contact your local government office since this would probably be governed at that level.

Yes, contact the local government. I know in NYC, a law was just passed banning flyers from being placed on cars. Best to make sure it's legal where you are before starting any big public campaign.

Here where I live, I know there are certain laws to follow regarding what you do. Learned the hard way... Was placing flyers on peoples windshields for one of my past businesses, and was thrown out of the shopping complex lol

Live and Learn!

yeah, where I live there are signs all over the place that make it clear that you need a permit to solicit. Definately check the laws in the areas that you plan to operate in.
