How Much Does a Fiberglass Pool Cost in North Dakota?

Based on a 2026 survey of independent fiberglass pool builders in the Thursday Pools dealer network, a standard fiberglass pool installation in North Dakota averages $90,000 for a small pool, $115,000 for a medium pool, and $130,000 for a large pool. Your final cost will depend on details like pool size, yard conditions, local permit requirements, and the optional upgrades you choose.

North Dakota’s freeze-thaw cycles are severe, with ground heave a real concern for anything buried in the soil. Loamy and clay-heavy soils throughout the eastern part of the state can create drainage challenges during inground pool installation. Rocky conditions are more common in the western Badlands-adjacent terrain around Dickinson and Minot. 

A local independent Thursday Pools dealer can evaluate your site, navigate local permit requirements, and help you build a pool package built for North Dakota living.

ASPEN (12′ x 25′)

Aspen is a compact, purposeful design built for North Dakota homeowners who want a capable pool in a manageable footprint. It’s a natural fit for suburban lots in Fargo, Bismarck, and Grand Forks, where yard space is finite but summer is worth every square foot of outdoor investment.

What Yard Conditions Affect Fiberglass Pool Installation Costs in North Dakota?

North Dakota’s terrain and soil conditions can vary significantly across the state, and those differences show up directly on the project bill. Before breaking ground, a professional installer will assess your site for conditions that may require extra preparation.

Soil Type

North Dakota’s geology creates distinct challenges across the state. Clay-heavy soils are common throughout eastern North Dakota, including the Red River Valley communities around Fargo, West Fargo, and Grand Forks, where dense, moisture-retaining ground requires careful drainage planning to protect the pool structure over time. In central and Western North Dakota, around Bismarck, Minot, and Dickinson, soil conditions are more varied, with rocky formations appearing in the Missouri Coteau and Badlands-adjacent terrain. Sandy soils, while less common, are found in specific geological areas and may need additional reinforcement.

Slope and Grade

While much of Eastern North Dakota is famously flat, the Missouri Coteau in the central part of the state and the rugged terrain around Minot and Dickinson can produce sloped properties. When slope conditions do occur, grading costs in North Dakota are significant and a reflection of the challenging ground conditions and the additional equipment required.

Backyard Access

North Dakota’s remote geography, long haul distances, and rural properties make access one of the most significant cost variables in pool installation. Even within urban areas like Fargo and Bismarck, tight driveways, mature trees, and challenging lot configurations can require specialty equipment or crane service.

 

AVERAGE ADDITIONAL YARD-RELATED EXPENSES IN SOUTH DAKOTA
Excavating Sandy Soil	$1,520
Excavating Clay-Heavy Soil	$2,850
Excavating Rocky Soil	$1,250
Above-Average Slope Requiring Extra Grading	$10,000
Limited Yard Access	$10,000

Based on 2026 pricing data, the most significant site-condition upcharges in North Dakota are for slope and access, each averaging $10,000.

What Are North Dakota’s Swimming Pool Fence Requirements?

North Dakota’s residential pool fencing and barrier regulations are set at the local municipality level. The City of Fargo, for example, requires private swimming pools be surrounded by a fence or barrier meeting the following requirements:

• The barrier must be at least 48 inches tall and positioned at least 4 feet from the outside of the pool.
• All openings in the barrier must prevent passage of a 4-inch-diameter sphere.
• Gates must be self-closing and self-latching, maintaining a positive close and latch when released from 6 inches open.
• Where the self-latching device is less than 54 inches above the bottom of the gate, the release mechanism must be located on the pool side of the gate.
• An existing pool enclosure must not be removed, replaced, or changed in a way that reduces its effectiveness as a safety barrier.

Requirements vary across North Dakota’s municipalities. The City of Grand Forks requires a 5-foot pool enclosure with self-latching gates, slightly stricter than Fargo’s 48-inch standard. The City of Bismarck’s Building Inspections Division enforces barrier protection for residential swimming pools independently of the Environmental Health Division, which handles only public and semi-public pools. Always verify current requirements with your local building department before installation.

For a 300-linear-foot basic pool fence, North Dakota dealers estimate an average cost of $10,000. Final pricing varies by material, height, gate requirements, terrain, and local ordinance compliance.
