Step 1: Determine Your Municipality's Requirements
Contact your local building department to confirm specific requirements, as they vary significantly across Rhode Island's 39 cities and towns.
Step 2: Prepare Your Application
Gather all required documentation and drawings. Many municipalities now accept electronic submissions through the statewide permitting portal.
