Construction Services & Inspections

• Construction Services & Inspections (CSI) is the main point of contact for your project. CSI will help you understand the process, guide you to assembling a complete permit application and route your project to all of the City divisions that will need to review and approve your project.
• In addition to complying with the Minnesota Building Code, your project must comply with the Duluth Unified Development (Zoning) Code, Minnesota Fire Code, and Duluth Engineering ordinances and policies.
• Contact the Fire Marshal's office in the Duluth Life Safety Division at (218) 730-4380 to verify the distance from the nearest fire hydrant to the proposed building. The Minnesota Fire Code requires that your proposed dwelling needs to be within a certain distance from a fire hydrant.
• Contact the Duluth Engineering Division at (218) 730-5200 to discuss available utilities, utility connection costs, driveway permits, and other permits for work in the right-of-way (street or alley).
• If your project is in close proximity to a creek or shoreline or located in a wetland or flood hazard area, it may be subject to additional regulations and require additional permits or special approvals. Contact Construction Services at (218) 730-5240 to discuss the details. 
• You will need to submit a site plan based on a boundary survey. Please review the Survey and Site Plan Drawing Requirements. St. Louis County keeps an updated list of professional land surveyors in the St. Louis County area on their website here.
• Minimum required setbacks from property lines depend on the zone district where your property is located and building code requirements. Usually zoning setbacks are greater than building code setback requirements. You can find the zone district and setback requirements on the Zoning Regulations web page. You will need to find your property on the Zoning Map, then look for setback requirements for that district. You can also call Construction Services at (218) 730-5240 for help determining the zone district and setback requirements.

Both owner's and the contractor's (if applicable) signatures are required on the front page of the application.
• Shoreland Permit – applicable only if there is any land disturbance located in a shoreland buffer zone. City staff is responsible for filling out necessary paperwork for this application.

Plans meeting these criteria may be submitted digitally or on paper. If you are drawing your plans on paper (not on a computer), you will need to use tools of the trade: good quality paper, an architectural scale, a straight edge, and dark pencil or ink. Your contractor, a drafter, or an architect may be able to prepare plans for you.

• Special Approvals. If your project required Planning Commission or City Council approval, you will need to submit proof of approval, such as the action letter, at time of building permit application submittal.

Building Permit Fees. Building permit fees are based on the valuation of the project. For new residential buildings, residential additions, decks, and garages, the valuation is based on a standard per square foot cost.
