Answers from the rulebook for Fergus Falls
Fergus Falls’s own rules
Building permitRequired
Work listed in City Code § 10.20 inside Fergus Falls city limits.
Common building-code exemptions listed by the City include garden sheds and playhouses not exceeding 200 square feet, fences not over 7 feet, retaining walls not over 4 feet, decks not more than 30 inches above grade without frost footings and not attached to a structure, and playground equipment.
The permit must be obtained before work begins; unpermitted work is subject to double the permit fee unless the building official waives that provision because the work was required by an emergency.
New-structure permits are issued only to state-licensed contractors; existing-structure permits are issued to state-licensed contractors or resident owners who homestead the property.
A permit becomes invalid if work is not started within 180 days or is suspended or abandoned for 180 days; written extensions may not exceed 180 days each.
“Permits are required to construct, enlarge, alter, repair, move, demolish”

Unanswered questions are usually a sign that Fergus Falls publishes no rule on the point, not that none exists. Otter Tail County’s page lists the county offices to call.
