Grow facility signage
Licensing & registrationLast verified Nov 1, 2026
A grow needs a sign visible from the road, perimeter or main entrance. It must be at least 18 by 24 inches with 2-inch black letters on white, showing business name, address, phone number and license number.
Why it matters
Signage is checked at the start of every grower inspection, and it's easy to get the size or contents wrong.
Applies to Grower/Processor/Dispensary/Transporter/Lab
