Pool Cost Guide

How much does an inground pool cost in Idaho?

The Treasure Valley is a small pool market with a short season, so a handful of builders set the schedule and most pools are contracted in winter to be dug in spring. Labor runs below the US average, and most lots are a standard dig, though river-bottom cobble can slow excavation.

Statewide, a medium inground pool with a basic deck runs about $56K – $104K installed.

Registration is not a license

Idaho requires contractors to register with the state under the Idaho Contractor Registration Act, but registration only confirms the business is on file with insurance; it does not test competency. The trades are licensed: the electrician wiring the equipment pad and the plumber running the lines must hold Idaho electrical and plumbing licenses. Look up the registration and the trade licenses through the Division of Occupational and Professional Licenses, then check references, years in business and a certificate of liability insurance.

Barrier, permit and inspection basics

Pool barrier rules in Idaho come from the building code adopted by each city or county. Boise and the surrounding cities enforce the residential pool barrier provisions: typically a 48-inch barrier with self-closing, self-latching gates, plus door alarms or self-closing doors where the house forms part of the barrier. Confirm the local amendments before design.

Every inground pool needs a building permit from the city or county, plus electrical and plumbing permits. Expect inspections at excavation and steel, plumbing and electrical rough-in, bonding, and a final barrier check. Fees are set locally and are usually valuation-based.

Season, soil and timing

The practical construction window in the Treasure Valley runs from roughly April through October, and shotcrete and plaster need frost-free nights. Most pools are contracted between fall and early spring so the dig can start as soon as the ground thaws. Soils are generally workable, but lots near the Boise River often have cobble and gravel that slow excavation and can raise the dig price.

Frequently asked

What is the average cost of a pool in Boise?
Our model puts a medium gunite or fiberglass pool with basic equipment and a modest deck a little below the national range, reflecting Boise labor costs. A heater is nearly standard here, and a cover extends the short season. Use the estimator for a ZIP-level range.
Do pool builders need a license in Idaho?
Idaho requires contractor registration, not a competency license. The electrician and plumber must hold state trade licenses. Check registration and trade licenses through DOPL, then check insurance and references.
Is a pool fence required in Idaho?
Yes, under the building code adopted by your city or county: typically a 48-inch barrier with self-closing, self-latching gates, plus door alarms or self-closing doors where the house is part of the barrier.
How long is the pool season in Idaho?
Construction runs roughly April through October. A heater and a cover extend swimming from late spring into early fall.

Fall or winter. Builders fill their spring slots early, and a winter contract is usually dug in April and swimmable by early summer.
