Building Permit Application Process
When is a building permit required?
Most projects require a building permit. State law requires that permits be issued before work begins.
Homeowners are typically allowed to perform work on the building they occupy after the building permit is issued.
By state law, commercial projects are required to have a design professional prepare the project documents.

Please contact us if you’re unsure whether your project requires a permit or not.
Once you have submitted your permit application, it will undergo plan review. Most projects require a plan review, which involves staff examining the project plans to verify that the plans comply with specific code requirements.
The City of Northfield has adopted the 2018 International Code Council codes with 2020 Minnesota Amendments. This review minimizes misunderstandings and construction delays for the projects.
Timeline for reviews
For residential projects allow at least five business days for the plan review process. For commercial projects allow at least 10 business days for the plan review process. These time frames are based on the assumption that the application was complete, and was submitted with no major code violations. For very large commercial projects the plan review process may take longer.
Minnesota State Law requires that residential contractors be licensed by the State of Minnesota.
Most permits will require a fee to be paid.
The amount of the fee varies depending on the scope of work planned. Permit fees are paid after the plan review and when the permit is issued.
Pay for a permit
You have the option to pay by credit card or electronic check. A 3% convenience fee will be adding to credit card payments. A $3 convenience fee will be added to electronic check payments.
Do not pay until your permit has been issued with your permit number and fee amount total. You will need to enter your permit number found in the email from the Building Inspection Department and the fee amount.
Depending on the project, there may be required inspections at various points both during and after construction is completed.
