How to get a building permit in Duluth, MN
Step 1: Prepare your documents
First, you’ll need to gather site plans, construction drawings, contractor license/credentials, and the estimated valuation of the work. Use the residential or commercial permit checklists provided by Duluth to ensure your application is complete.
Step 2: Submit Duluth building permit application online
Go to Duluth’s ePlace portal to submit your application electronically. Upload your documents, select the permit type, and supply project details (valuation, permits, scope).
Step 3: Plan review
The city conducts an intake review to check if required items are included, then a technical review across departments (construction, zoning, inspections). Commercial or complex projects are subject to more detailed review; minor residential or remodeling may have a faster path.
