I’ve had multiple friends try to start businesses that got stuck on this: You can’t really get permits until you have the property and start drawing up plans.
For simple businesses like a retail store in a location that has other retail it’s not too risky to bet that you’ll be approved, too.
For businesses with unique needs or that happen to be in the public crosshairs, you’re putting a lot at risk in the process.
The process favors big companies and developers who have established relationships and “connections” with the planning boards.
The situation is even wilder in some other countries, both more and less corrupt than the average US municipality. In some places you’re not getting a permit at all without a sizable bribe, or having an in with the planning board.
In my city one of the aspiring developers tried to run an expensive political campaign to get a family member into an office that could have helped with their approvals. People caught on and didn’t like it one iota.
