The fine print

In plain English

BY RIGHT No hearing needed

If your business is on the by-right list, you can occupy a space in this district and open — no zoning hearing. Building permits and licensing still apply, but the use itself is already allowed.

SPECIAL Approval first

Special-approval uses can work here too, but they go through a public review before opening. Plan for extra time and possible conditions — we'll tell you which path a space needs.
