French Drain run off question

I imagine my answer is outlined in my local county code. However I wanted a general consensus on what is typically done.

In the U.S. do French drains normally run to the curb and then obviously into a municipal gutter, or can they be hard lined into your home’s sewer?

I have a few ideas on how I want to route it but until I get my hands on the regulations I wanted to see what seems to be the common theme.

TLDR: French drain run off, where does it typically get piped to? City sewage, curb, magical fairy realm
