Construction Services & Inspections

Residential Project Guide

If you are planning a residential construction project and need help locating what you need to know and what to do for permits and inspections, you have come to the right place! The following information is only applicable for projects in one-unit and two-unit dwellings.

Minnesota rules require that the permit holder be an owner or licensed contractor. The permit holder will be responsible for all corrections and compliance with applicable codes, so if you are hiring a contractor, it is best practice for the contractor to apply for and hold the permit. Please note - If your proposed dwelling has two-units or has an active rental license, a licensed contractor will need to be the permit holder for electrical, plumbing, HVAC and gas piping permits.

Are you planning on building a new single-family dwelling, two-family dwelling, townhouse or detached accessory dwelling unit? If so, please click below for more information.

  • 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 Residential Survey and Site Plan Packet. 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. 
  • To help ensure a complete building permit application at time of submittal, please use the Residential Plan Review Checklist for New Dwellings. A completed checklist must be submitted along with your application and plans.
  • Residential Plan Review Building Permit Application. Be sure all areas are completed such as valuation, contact information, and required applicant signatures.
  • Erosion Control Permit Application. The Erosion Control Permit Application is a Duluth Engineering Division permit. You will submit this along with your building permit application to the Construction Services office. It will then be routed to the Duluth Engineering Division to be reviewed. Both owner's and the contractor's (if applicable) signatures are required on the front page of the application.
  • Shoreland Permitapplicable 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.
  • HVAC, Plumbing, Gas Piping, and Electrical work requires separate permits. These permits will not be issued until the building permit is issued. If you would like to read more information regarding these types of permits, please visit this page.
  • Boundary Survey. You will need a boundary survey signed by a professional land surveyor licensed in the State of Minnesota. Please review the Survey and Site Plan Packet. St. Louis County keeps an updated list of professional land surveyors in the St. Louis County area on their website here.
  • Building Plans. Building plans, including a site plan, must be drawn to scale, dimensioned, drawn on suitable material, legible, and of sufficient clarity and detail to show all work proposed, how it will be constructed, the location of the work on the site and/or in the building, how it will comply with the building and zoning codes, and other applicable regulations. 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.
  • Site Plan. Please see the Survey and Site Plan Packet, and page two of the Residential Plan Review Checklist for site plan requirements.
  • Elevation Drawings. Please see the Sample Drawings, and page two of the Residential Plan Review Checklist for elevation drawing requirements.
  • Foundation Plan (this may be incorporated with the basement plan). Please see the Sample Drawings, and page two of the Residential Plan Review Checklist for foundation plan requirements.
  • Floor Plan(s). Provide complete plans for each floor, including the basement and finished attic space. Please see the Sample Floor Plan, and page two of the Residential Plan Review Checklist for floor plan requirements.

  • Stair Section. Please feel free to use the Residential Stairs Form for guidance.
  • Structural Loads. Confirm on plans that bearing for beams has a continuous load path to the foundation. Be sure to use the Residential Header & Girder Span Requirements Form to ensure proper size.
  • Engineered Drawings & Engineered Product Design - if applicable. If something cannot be reviewed within the prescriptive requirements of the MN Residential Building Code, a structural engineer licensed in the State of Minnesota may be required to stamp and sign structural plans.
  • Roof & Floor Truss Shop Drawings. These can typically be a delayed submittal, unless the Plans Examiner reviewing the plans determines they are necessary to complete their review.
  • Deck Plans - if applicable. Please see the following link to the Residential Deck Application Packet for items required for review.
  • Manufactured and Modular Homes. If your project is a manufactured home or modular home, the HUD or IBC Seal numbers will be required prior to final inspection.
  • Septic System or Well. If your lot requires a septic system and/or well, you will need to submit proof of approval of the septic system from St. Louis County at the building permit application submittal, and proof of a compliant well from the Minnesota Department of Health prior to Certificate of Occupancy.
  • 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. The state surcharge fee, required, is also based on the valuation of the project. Plan review fees are required and are a percentage of the permit fee. Construction Services will calculate the valuation for new residential buildings, residential additions, decks, and garages to determine total permit fees, which are paid when the permit is approved. 

If you'd like to estimate your permit fees, you can use the Residential Valuation Schedule Form to calculate the valuation per square foot. Then, you can use the Permit Fee Calculator or Fee Schedule to calculate fees.
