Duluth, Minnesota Building Department 2026: Permits, Inspections & Services

Duluth Building Permits, Inspections & City Services

If you are building a deck, replacing a roof, remodeling a kitchen, adding a garage, installing a furnace, changing plumbing, opening a business or constructing a new building in Duluth, the office you will usually deal with is the City of Duluth Construction Services & Inspections (CSI).

Duluth Construction Services & Inspections Contact Information

Jurisdiction matters. These instructions apply to property under the City of Duluth’s permitting authority. A Duluth mailing address does not by itself prove that the parcel is inside Duluth city limits. Property outside the municipal boundary may fall under St. Louis County, a township or another local authority.

Which Duluth Permit Does Your Project Need?

A single project can require more than one permit. Duluth’s guidance separates structural, plumbing, HVAC, gas piping and electrical work rather than treating everything as one building permit.

Before choosing an application, open the City’s official permit-type table. It shows whether a permit uses a flat or valuation-based fee, whether plan review is required and what licensing requirements apply.

Projects That May Not Need a Duluth Building Permit

Duluth identifies several building-permit exemptions. Common examples include:

• One-story detached sheds, playhouses and similar accessory structures measuring 200 square feet or less.
• Fences up to 7 feet high.
• Certain retaining walls up to 4 feet high when the City’s listed conditions are met.
• Sidewalks and driveways that are not part of an accessible route.
• Certain detached platforms and decks no more than 30 inches above adjacent grade that meet the City’s other exemption conditions.
• Painting, wallpaper, tile, carpeting, cabinets, countertops and similar finish work.

A building-permit exemption is not permission to ignore zoning, setbacks, utilities or trade permits. A small shed may not need a building permit but still has to be located legally on the lot.

For the City’s complete exemption list, use Duluth’s official “About Permits” page.

How to Apply for a Duluth Building Permit Online

Duluth’s permit applications are submitted through ePlace. The easiest way to avoid delays is to do the zoning research and gather documents before starting the online form.

1. Check the property first. Confirm the project is within Duluth’s jurisdiction and determine the property’s zoning district, permitted use and required setbacks.
2. Identify every permit involved. Open the official permit-type list. Check building, plumbing, HVAC, gas piping and any other work included in your project.
3. Open the official application page. Go to Duluth Apply Online and follow the ePlace link.
4. Create or sign into your ePlace account. The City’s ePlace information page includes account instructions and access to the portal.
5. Select the permit that matches the work. Enter the project address, work description, owner or contractor information and requested project details.
6. Upload the required documents. Add the site plan, construction drawings, specifications, truss information, equipment information or other files required for that permit type.
7. Submit the application. After submission, CSI checks the application for completeness and routes required reviews to the appropriate City departments.
8. Respond to review comments. A plans examiner or another reviewer may request corrections, clarification or revised drawings. Supply the requested information through the process rather than starting work.
9. Pay the invoice when instructed. Once review is complete, the Permit Coordinator sends the applicable invoice through ePlace. Some larger commercial plan-review fees are due earlier.
10. Wait for the issued permit. After payment and approval, obtain the issued permit, inspection card and approved stamped plans. Keep required documents available at the job site.

What to Prepare Before You Apply

The exact package depends on the project, but having these items ready can prevent an incomplete application:

• Correct property address and owner information.
• A clear description of the proposed work.
• Contractor information and applicable Minnesota license details.
• Site plan showing existing and proposed structures where location matters.
• Dimensions and distances to property lines.
• Floor plans, elevations or construction drawings when required.
• Structural details for additions, decks, garages and similar projects.
• Truss information when applicable.
• Mechanical or equipment specifications for relevant work.
• Estimated construction value when the permit uses valuation.

Duluth publishes useful project documents rather than expecting applicants to guess. Visit the City’s Forms and Handouts library for the residential checklist, deck packet, detached-garage packet, sample drawings, stair information, commercial checklist, energy worksheet, site-plan packet, solar checklist and other official PDFs.

Deck and garage planning

For a residential deck that requires a permit, Duluth advises applying roughly two weeks before the planned start. Typical deck inspections can include footing, framing and final inspections.

For a standard detached residential garage, the City recommends allowing roughly two weeks to a month before the desired start because the plans and site information must be reviewed. Detached accessory structures over 200 square feet normally require a building permit.

Duluth Building Permit Fees in 2026

There is no single price for every building permit. Some fees are valuation based, while several common residential permits moved to flat fees in 2026. A Minnesota state surcharge can also apply.

The City’s published flat fees above include the stated $1 state surcharge. Always confirm the current amount on the official Duluth permit fee page before budgeting.

Plan review fee

When plan review is required, Duluth generally calculates the review fee at 65% of the building permit fee. Decks and garages are listed as exceptions to the plan-review fee.

For commercial and 3+ family residential projects valued over $250,000, the applicable plan-review fee is due when the application is submitted, and review does not begin until that fee is paid. Once plan review has started, that fee is not refundable.

Capacity Availability Fee for new or expanded development

New structures or expanded uses connected to the regional wastewater system may also trigger a Resource Renew / WLSSD Capacity Availability Fee (CAF). Duluth’s 2026 information lists $940 per applicable unit for new dwelling units. The City has announced that the CAF changes to $1,200 per unit effective January 1, 2027.

Check Zoning and Setbacks Before Designing the Project

A common mistake is preparing full construction plans before checking whether the structure can legally fit on the lot.

Duluth recommends this order:

1. Open the City’s zone district, setback and permitted-use guide.
2. Search the property through ePlace or the City’s Planning and Land Use Map.
3. Identify the property’s zoning district.
4. Check the permitted-use table to make sure the proposed use is allowed.
5. Review the standards for that zone, including lot dimensions, structure height and setbacks.
6. Use those requirements when preparing the site plan.

If you cannot identify the correct zone or setback, contact Duluth Planning at 218-730-5580 or planning@duluthmn.gov before submitting the permit.

How Duluth Building Inspections Work

Permitted work must be inspected at the required construction stages. The inspector assigned to the permit and the inspector’s phone number are shown on the issued permit.

Request an inspection

1. Check the inspection card for the next required inspection.
2. Find the assigned inspector’s contact information on your permit.
3. Call at least 24 hours or one business day in advance of the desired inspection.
4. Give your name, phone number, project address, permit number and inspection type.
5. Make sure the work is ready and accessible.
6. Keep the issued permit and approved plans at the job site.
7. If corrections are required, complete them before requesting reinspection.
8. Request the final inspection when the permitted work is complete.

More detail is available on Duluth’s official inspection information page.

Certificate of Occupancy

For new buildings and certain changes of occupancy, a Certificate of Occupancy may be required before the space can legally be occupied. After the final inspection, the construction inspector initiates the process when applicable. Duluth states that issuance can take up to three business days. Projects that do not require a Certificate of Occupancy may receive a Letter of Completion after final approval.

Search Duluth Permit and Property History

If you are buying a property, planning a remodel or trying to understand earlier work, you can search permit and property information through ePlace.

1. Open Duluth’s Permit or Property History page.
2. Choose the ePlace property-history search.
3. Search the Duluth address.
4. Sign into a public ePlace account when additional record details require it.
5. Review available permit and property information.

Need older records? For permit history from before 1992, contact Construction Services at 218-730-5240 or use the City’s Property History Request process.

Building Codes Used in Duluth in 2026

Duluth’s Construction Services pages identify the 2020 Minnesota State Building Code as the current building-code framework. Minnesota DLI also confirms that the 2020 State Building Code remains in effect for the principal building and residential code areas, with later supplements and specialized code updates where applicable.

The 2024 Minnesota Commercial Energy Code has been effective since January 5, 2024.

You can review Minnesota’s official code resources through the Minnesota Department of Labor and Industry. For a broader explanation of how city and state code adoption works, see our City Building Code guide.

Electrical permits are handled by Minnesota DLI

This is an important Duluth-specific detail: since June 4, 2024, residential and commercial electrical permitting and inspections have been handled by the Minnesota Department of Labor and Industry rather than Duluth CSI.

For electrical work:

1. Go to Minnesota DLI’s electrical permit page.
2. Choose the applicable contractor or homeowner permit process.
3. Submit the state electrical permit.
4. Use the inspector information supplied with the permit to request the electrical inspection.

For electrical permits filed on or after August 17, 2026, Minnesota has adopted the 2026 National Electrical Code (NEC). Permits filed before that date are governed by the 2023 NEC.

Who Can Pull a Permit?

The owner or the contractor performing the work is responsible for obtaining the required permit. If the person performing the work is not the owner, Minnesota contractor-licensing rules generally apply.

Duluth notes that residential contractors working on one- and two-family homes and townhouses are subject to Minnesota licensing requirements. Electrical and plumbing trades have their own state licensing rules. Mechanical contractors may also need the required Minnesota mechanical contractor bond.

Before hiring someone, use the City’s contractor licensing guidance and follow its links to Minnesota’s official license lookup.

Commercial Projects: Check the Building Before Signing a Lease

A business moving into an existing Duluth space can still face building, fire, accessibility, sprinkler, zoning or occupancy requirements even when little construction is planned.

For a substantial commercial or 3+ family project, the City encourages early coordination and offers pre-review meetings. This can identify expensive requirements before the design is finished.

A practical sequence is:

1. Confirm the proposed business use is allowed by zoning.
2. Discuss the intended occupancy with Construction Services.
3. Determine whether a Minnesota-licensed design professional is required.
4. Review the City’s commercial checklist and development guidance.
5. Use a pre-review meeting for complex projects.
6. Only then finalize plans and submit the permit application.
