Is pulling permits a waste of time/money?

[Adam Lowe]

So I’m doing my 1st flip and I’ve been getting a mixed response on wether or not pulling permits is a good idea. On one side I’m being told that it’s a must and that it’ll hurt me once the inspector comes through. Conversely, other people say it’s more time/money and as long as it’s up to code it shouldn’t be questioned? Any thoughts or past experiences would be greatly appreciated!
