Deck Construction Permits in North Dakota

The Building Code in North Dakota

North Dakota State Building Code, 2024 IBC/IRC based, effective January 1, 2026, opt-in for local jurisdictions

The North Dakota Dept. of Commerce, Division of Community Services maintains the State Building Code, and state law requires that any city, county, or township choosing to enforce a building code must adopt this state code rather than writing its own. On September 11, 2025, eligible jurisdictions voted to adopt the 2024 editions of the IBC, IRC, IMC, and IFGC with state amendments, which took effect January 1, 2026. Under the code, a deck more than 30 inches above finished grade requires a permit in jurisdictions that enforce it; ground-level decks under 200 square feet and below 30 inches are typically exempt. Adoption itself remains optional for local governments. Frost depth ranges from 48 inches in the east to 60 inches in western North Dakota, and the City of Fargo's own guidance specifies a minimum footing depth of 5 feet (60 inches) below grade.

Quick Facts

Who Sets the Rules

A genuine statewide code, but adoption is still a local choice

North Dakota is unusual for the region in having a real state code that any adopting jurisdiction must use rather than writing its own. But the decision to enforce a building code at all remains local, so rural townships that never opted in have no deck permit requirement regardless of size.

A very recent update, voted on a specific date

North Dakota's eligible jurisdictions voted on September 11, 2025 to adopt the 2024 IBC and IRC, which became effective statewide January 1, 2026, a genuinely current code cycle backed by a specific, documented adoption vote.

Fargo goes deeper than the general statewide range

While North Dakota's frost depth generally runs 48 to 60 inches depending on region, Fargo's own deck guidance specifies a minimum footing depth of 5 feet, 60 inches, a specific local figure at the deep end of the statewide range.

A real, specific dollar threshold for contractor licensing

The North Dakota Secretary of State requires any contractor performing work valued at $4,000 or more to obtain a state contractor's license, a genuine statewide licensing floor that applies regardless of whether the local jurisdiction enforces the building code itself.

Trade permits reach even the areas with no building code

Electrical work goes through the State Electrical Board and plumbing through the State Plumbing Board regardless of whether a specific township has adopted the general building code, so a deck that needs no building permit at all can still require a real state trade permit once wired.

What people get wrong

The most common mistake is assuming North Dakota's genuine statewide code means the rule is the same everywhere. Adoption itself remains optional for each local government, so the practical answer still depends on whether your specific city, county, or township has opted in.
