Except for 1 & 2 family dwellings, IRC townhouses and residential accessory buildings, the applicant for a permit shall provide an estimated job value at time of application.

Valuations for 1 & 2 family dwellings, IRC townhouses and residential accessory buildings are calculated using the current valuation table.

A plan review fee is applicable when plan review is required, with the exceptions of decks and garages. Plan review fees for commercial and 3+ family residential projects with a valuation over $100,000 are payable at the time of permit application, and the plan review for these projects will not begin until the plan review fees are paid. Plan review fees for all 1 & 2 family residential and for commercial projects with a valuation less than $100,000 are payable at the time the permit is issued. Plan review fees are not refundable once the review has started. The plan review fee is equal to 65% of the permit fee.

In addition to regular permit fees, fees for work without permits are payable in accordance with Duluth Legislative Code Section 10-2 and MN State Building Code Section 1300.0160, resulting in a double permit fee.
