# Inground pool cost in Arizona: price range, barrier law and ROC licensing

Updated 2026-10-11. A planning range from published sources, not a quote.

For a 500 square foot Arizona pool, PriceAPool prints $75,000 for concrete, $57,000 for fiberglass and $46,000 for vinyl, and our planning range is $45,000 to $88,000. Shasta Pools, a builder, averaged $73,459 in 2025. Arizona requires a barrier at least 5 feet high around a new residential pool, with limited exceptions.

## What an inground pool costs in Arizona

Our planning range, built from published guides and moved by the state, next to the state figures a source prints. Our range and HomeAdvisor's national range, moved by the state factor, end at the same top here, so we show it once.

**Planning range, 500 sq ft pool: $45,000 to $88,000.** Water area times the published per square foot rates, moved by a state factor of 1.00. Priced that way alone, the top would run higher, so we hold the top at HomeAdvisor's typical top for any size, moved by the same factor. It covers the pool, excavation, equipment and plaster, and leaves out the deck, fence and spa.

| Source | Dated | What it prices | Concrete | Fiberglass | Vinyl |
|---|---|---|---|---|---|
| PriceAPool, Arizona pool cost | 2026, no day printed | The state figure for a 500 sq ft pool, permits in, deck and spa out | $75,000 | $57,000 | $46,000 |
| PriceAPool, Arizona pool cost | 2026, no day printed | Phoenix, same 500 sq ft pool | $78,000 | $59,000 | $48,000 |
| Shasta Pools, Arizona costs | updated May 29, 2026 | Installed pools by type; the page does not give a size | $40,000 to $120,000 | $55,000 to $110,000 | $30,000 to $60,000 |

Arizona is the one state where a builder prints its own numbers. Shasta says it averaged $73,459 across 377 pools in 2025, concrete and fiberglass together, with its ranges wider than PriceAPool's single points. PriceAPool's text says Scottsdale prices run 15 to 25 percent above Phoenix, while its table lists Scottsdale below Phoenix. Our range follows the cost of living, which is close to the national figure here. None of this is a quote.

## The rules in one look

- **Barrier or safety feature:** A barrier at least 5 feet high around most home pools (ARS 36-1681), with listed alternatives and exceptions.
- **License:** A contractor you hire needs an ROC license that covers pools: residential class B-5 or B-6, or a B-4 whose scope includes B-5.
- **Who sets local rules:** Your city, which may add to the statute and sets permit fees and inspections.
- **Season:** PriceAPool says Phoenix and Tucson offer roughly 10 to 11 months without a heater; monsoon season can delay pours.

## What changes the bill in Arizona

Under the ground, PriceAPool says caliche hardpan can add $3,000 to $12,000 during excavation, and rocky or high-water-table conditions $10,000 to $25,000 (a generic line it prints on every state page). Above it, Shasta says the dry, hot air raises evaporation and water use, and that cooling can cost more or less depending on whether you choose a cooling system or the aerator most installs include. Shasta puts a spa added to a pool at $12,000 to $18,000.

PriceAPool prints permit fees of $1,200 to $2,500 and $1,600 to $2,880 in different sections and says monsoon season can delay pours by 2 to 3 weeks. PriceAPool lists concrete at 12 to 22 weeks in its table and 8 to 14 weeks in its FAQ, fiberglass at 3 to 6 weeks and vinyl at 4 to 8 weeks. Ask your city what it charges and when it can inspect.

## Arizona's pool barrier law

Arizona Revised Statutes 36-1681 applies to a pool or other contained body of water at least 18 inches deep at some point, wider than 8 feet at some point and meant for swimming. The enclosure must be at least 5 feet high on the outside, stand at least 20 inches from the water's edge, and have no opening that lets a 4 inch sphere pass. A gate must be self-closing, self-latching and open outward, away from the pool.

The statute allows alternatives where the house forms part of the enclosure, such as a 4 foot barrier between the pool and the house or a key-operated motorized safety cover, and it exempts pools built before the article took effect, homes where every resident is at least 6 years old, and cities with an equal or stricter ordinance. Read the full text with your building department, because a city may add its own rules.

## Who may build a pool in Arizona

Arizona licenses contractors through the Registrar of Contractors (ROC). The residential pool classes are the B-5 General Swimming Pool Contractor and the B-6, which adds solar heating. A B-5 may build and repair pools and spas, install code-required pool barriers and run utilities from the service point to the pool equipment. The rule for the B-4 General Residential Engineering Contractor class says its scope also includes B-5 work, so a B-4 holder can be licensed for pools too. Some other general residential classes must subcontract pool work to an appropriately licensed contractor. Arizona Revised Statutes 32-1121 lists exemptions: work under $1,000 that needs no local permit, and an owner who improves their own property for their own use and does not sell or rent it within a year. A pool built for a client fits neither, so a contractor you hire should hold an ROC license that covers pools. Even an owner-builder still needs the permit and inspections, and most owners hire a licensed contractor.

Check the license number on the quote at the ROC, and that its classification covers pools, before you sign. The ROC site blocks automated visits, so we did not open it, and we list it that way below. The classification and exemption text above comes from the Arizona Administrative Code and the statute, which we did open.

## Climate and season in Arizona

Shasta says concrete and fiberglass resist the heat and sun and that vinyl liners fade and wear faster, so vinyl is rarely built in Arizona. It says Arizona pools do not need winterizing and that a plaster surface is redone about every 10 to 12 years and pebble every 15 to 18. It puts monthly maintenance at $65 to $200.

PriceAPool says Phoenix and Tucson offer roughly 10 to 11 months of usable pool season without a heater, and that summer water can pass 90 degrees Fahrenheit, which is why chillers and shade structures are common upgrades. Shasta is a builder and PriceAPool is a cost calculator, so ask local builders what they see.

## Questions people ask

**How much does an inground pool cost in Arizona?** PriceAPool prints $46,000 to $75,000 by type for a 500 square foot pool, our planning range for that size is $45,000 to $88,000, and Shasta prints $40,000 to $120,000 for concrete. A planning range, not a quote.

**How tall must an Arizona pool fence be?** Arizona Revised Statutes 36-1681 sets the enclosure at least 5 feet high on the outside, at least 20 inches from the water's edge, with a self-closing, self-latching gate that opens outward. It does not apply where every resident is 6 or older, and the house can form part of the enclosure with other protection. Your city may add rules.

**What license does an Arizona pool builder need?** A contractor you hire needs a license from the Registrar of Contractors that covers pools: the residential B-5 General Swimming Pool class, the B-6 (the same scope plus solar heating), or a B-4 whose scope includes B-5 work, all described in R4-9-103. Check the license number and classification at the ROC before you sign.

**Does caliche add to the cost of an Arizona pool?** PriceAPool says caliche hardpan can add $3,000 to $12,000 during excavation. Ask whether the quote assumes it or leaves it as an extra.
