Thinking About Building Your Own Pool?

A pool company writing a guide like this is expected to skip the upside. We won’t, because a lot of the owner-builder pitch is true.

Saving money is almost always smart. Most of us also have a story about the time it wasn’t: the discount part that failed, the weekend repair that ended with a professional’s bill anyway. A pool can become that story, and it’s the one project you can’t easily tear out and start over. The rest of this guide covers what the sales pitch leaves out.

Building a pool in Arizona normally requires a license from the Arizona Registrar of Contractors (ROC). The owner-builder rule is an exemption from that requirement, and it’s narrower than most people are told. Here’s the operative language:

That gives you exactly three ways to get the work done:

A consultant’s “guys,” an unlicensed crew, or a friend who shoots gunite on weekends doesn’t fit any of those three.

The one-year rule. The pool has to be for you. The same statute says that selling or renting the home, or even offering it for sale or rent, within one year after completion is prima facie evidence you built it to sell. At that point the law treats it as contracting.

You become the contractor of record. When you apply for the permit, the City of Phoenix, Scottsdale, Mesa, Maricopa County and other Valley jurisdictions ask you to sign an owner-builder declaration citing this statute. From then on the permit, the inspections, code compliance, the pool barrier, and the quality of every trade’s work are your responsibility.

This is where most owner-builder “programs” run into the law.

For years, unlicensed operators used a simple line: “You’re the contractor. I’m only a consultant.” They designed the pool, chose the subs, set the schedule, bought the equipment, took your draws and paid the crews. Your name was on the permit and they ran the job.

In 2019 the Legislature passed Senate Bill 1397 and closed that door by adding consultants to the definition of “contractor”:

The broader definition also covers anyone who, for pay, builds or improves a structure “by or through others” or “directly or indirectly supervises others.” It doesn’t matter what the business card says or whose name is on the permit.

What about a licensed consultant? A few consultants in the Valley do hold an ROC license, which lets them legally plan, schedule and oversee the work. If you use a consultant at all, that’s the better choice. Then look at what the fee actually buys. Legitimate licensed help is tied to specific work: a written contract for a defined scope, a fixed price, a warranty on that work, and ROC accountability for it. Be careful with a flat “program” or “coordination” fee for managing a project that stays on your permit. You pay the fee, while the fixed price, the payment schedule, the single warranty and the Recovery Fund protection all point back at you. Ask for a written list of what they’re responsible for and what stays yours.

Their penalty becomes your loss. The fines fall on the consultant, but the damage lands on the person whose name is on the permit. If a consultant takes your draw and doesn’t pay the shotcrete crew, the crew doesn’t know the consultant. They know whose backyard they worked in.

Everyone pictures the excavator and everyone pictures the finished pool. The part in between is where owner-builders find out how much they know. A licensed builder answers every one of these questions before digging, because they answer them every week. You’d answer them once, with no practice, and live with the results for twenty years.

Equipment is the one big line item owner-builders are tempted to delay. It adds up fast when you buy it yourself:

Delaying the equipment costs money too. A common plan is to have the plumber rough in the lines, buy the equipment at the end, and bring the plumber back to set it. The lines have to hold pressure (often 35 psi or more) until everything is connected, so that second visit means a trip charge, capping and re-pressurizing, and another crew day for work they’d normally finish in one pass.

Check the warranty. Major manufacturers use tiered warranties. Equipment bought and installed by a pool professional usually gets the longest coverage, often including labor. Equipment bought online or installed by a homeowner often gets a shorter, parts-only warranty, and only if you register it on time. “Parts only” means the manufacturer ships you a part, and you pay someone to find the problem and swap it. Some product lines and longer warranties are sold only through trade professionals. Read the current warranty policy for any brand before you buy.

Watch the equipment markup. Owner-builder equipment often comes through a consultant who “has an account.” That’s a common way consultants make money beyond their design and permit fees. Selecting and buying materials for pay is contracting under the statute in chapter 3, and reselling equipment requires collecting and remitting sales tax.

The pitch rests on one assumption nobody checks: that you’ll save 25 to 30 percent. Here’s what usually happens to that number, using a $60,000 pool, near the top of the typical Phoenix-area range for a new pool in 2026.

The builder isn’t banking 25%. After overhead, a well-run builder often nets somewhere around 10%. On a $60,000 pool that’s about $6,000, earned over three months of construction for carrying every risk in this guide. There’s no $15,000 cushion hiding in the price.

The subs won’t give you the builder’s price. Excavation, steel and shotcrete crews do dozens or hundreds of pools a year for builders, working off a price book. You’re a one-time customer. Expect a verbal estimate or a range, and expect it to be higher than what a builder that feeds them work all year pays. A sub that undercut its best customer’s pricing for a homeowner wouldn’t keep that customer.

$6,000 is real money. Now weigh it against what it costs you:

• Your time. Expect three to four months end to end: roughly five or six weeks of design, engineering and permitting, then about ten weeks of construction when you’re running it. Add up the calls, inspections, supply-house runs and mornings waiting for crews. Divide $6,000 by those hours to see what you paid yourself.
• Your place in line. Phoenix pool season runs hot from spring through summer. Licensed subs are limited and they take care of the builders who keep them busy year-round. As a one-off customer you’re the fill-in job. If you owner-build, fall is your best window, and plan to finish before the holidays.
• No fixed price. A licensed builder signs a contract with a set price and absorbs the overruns. That’s part of what the margin pays for. An owner-builder has an estimate assembled from a dozen verbal ranges, and pays each trade as it finishes. By the time you realize costs are running high, you’re too far in to stop.
• Things builders absorb. Engineering, soils reports, plan review, re-inspections, a private utility locate, the caliche nobody priced, and the rework when two trades disagree about whose fault something is.

Pool loans are built around a licensed contractor: a fixed contract price, a state-regulated payment schedule, and a lender paying in stages against completed work. Without those, many lenders won’t finance an owner-builder project, and those that will usually charge more or offer shorter terms. Most owner-builders pay cash as each trade finishes, or borrow in pieces as bills arrive.

When you compare options, compare three numbers side by side: the total price, the cash you’d have to put in on day one, and the monthly payment. A slightly higher contract price financed on a long term with little or nothing down can leave you with more cash in the bank and a lower monthly payment than a “cheaper” owner-built pool paid for with savings and a short personal loan. Ask any builder you interview which lenders they work with and what their customers are actually paying. We’re glad to walk you through our current financing options.

This is where owner-builders get hurt the most.

When a licensed builder builds your pool, the builder answers for the finished product: the quality, how the trades fit together, and the leak that shows up in month eleven. If the plumber’s work fails, the builder fixes it and settles with the plumber afterward. That’s what the license, the bond and the ROC complaint process attach to.

Remember the “overhead” from chapter 1? Much of it is people. Coordinators schedule the trades and suppliers and keep you updated. A field superintendent with years in the trades checks each phase against the plans and catches problems before the next crew covers them up. A construction manager approves or rejects every sub’s invoice against the plan. On an owner-builder permit, you take all of those jobs, or you take the consultant’s word that “that’s just how they do it.”

The warranty call. With a builder, a problem in month eleven is one phone call, and if that doesn’t work there’s an office you can walk into. That’s a good reason to visit any builder’s showroom while you’re shopping. With an owner-built pool, what happens when the plumber who installed the in-floor system stops answering? He doesn’t market to homeowners and doesn’t need to. If you kept his ROC license number, you can file a workmanship complaint within the two-year window. If you didn’t, you have a phone number, and phone numbers change.

Arizona gives homeowners who hire a licensed pool contractor a strong set of protections. Almost all of them are written for a contract between a licensed contractor and a homeowner. On an owner-builder permit, that contract doesn’t exist.

A concrete pool goes through roughly twenty phases. As the owner-builder you schedule, sequence and check every one. Each has its own lead time and its own trade, and inspections are typically requested a day or two ahead. One day lost early can become a week lost at the end. Highlighted rows are inspections or permit steps.

If your calendar can’t absorb ten weeks of that on top of plan review, unusual soil and the occasional crew that doesn’t show, the savings won’t feel like much.

We won’t name companies. These are behaviors, and you can test each against chapter 3. Any one means the person is acting as your contractor. Two or more means they know it.

If you decide to owner-build, do every item on this list. Tick them off as you go; your progress is saved in this browser.

The pitch says 25%. Test it with real numbers. Put a licensed builder’s complete quote on one side and your own licensed bids and retail equipment prices on the other, then add the lines the pitch leaves out. The figures below are example numbers for a $60,000 pool. Replace them with yours.

Your number may still come out positive. It won’t be the number you were promised. The two lines the pitch never includes are the consultant’s fee, which is a contractor’s fee paid to someone without a contractor’s obligations to you, and your time, which nobody will reimburse.

The owner-builder exemption was written for people with construction experience who live in the home and don’t need a consultant. It wasn’t written for the general public, and it wasn’t meant to be someone else’s business model.

The Valley has a number of reputable pool builders. You’ll recognize them when you visit their showrooms, check their ROC records and read their reviews. There are also companies competing only on price, and that race to the bottom ends where you’d expect.

What you’re shopping for is value: who gives you the most for your money. You didn’t buy the cheapest car or the cheapest house you could find. You’ll pay what something is worth as long as the worth is there. So the useful question isn’t “how much can I save?” It’s “what does a professional builder give me that I won’t have otherwise?”

When you owner-build there’s real satisfaction in having done it, and there may be some savings. But nobody brought you any value. You supplied all of it, at your own risk, on your own time.

Among the top builders, the pools themselves are often similar, built by many of the same licensed trades. The difference is the experience: how you’re treated from the first design meeting through the day the water goes in, and every year after.

If you’ve read this far and still want to be your own builder, that’s your right, and we respect it. You don’t have to do it alone, and you don’t need an unlicensed consultant. We Fix Ugly Pools is a licensed Arizona contractor (ROC KA5-353555), so we can legally take on any part of your project with a written contract directly with you.

Before you sign anything with us, you get this in writing for your project. No guessing about who owns what.

Arizona gives you the right to build your own pool. Since 2019 it also treats anyone who manages that project for you, for pay, as a contractor, licensed or not. A legitimate owner-builder does the managing. A problem “program” does the managing and puts the permit in your name.

For the small group described in chapter 1, owner-building can make sense and save some money. For most people, it doesn’t. The risk is real, the savings are modest, and the person selling you the idea is usually the one person in the deal with nothing on the line. It can turn into an orphaned pool, a lien, an injured worker, or a consultant who has moved on.

Whatever you decide, decide with the facts. Know what the law says, keep your consultant inside it, and stay inside it yourself.
