The listing photos show blue water and a lounge chair. The equipment pad behind the side yard shows a pump with a rusty motor shell, a filter gauge stuck at zero and a heater with no date anyone can read. The pool inspection cost to find out what that pad is really worth runs $150 to $325 in California, per Angi’s 2026 data. Next to the price of the house, that’s a rounding error. It’s also the same kind of pad we stand at every week doing pool service and repair across Ventura County, and the listing photos never include it.

Most buyers assume the home inspector covered it. Usually the home inspector checked whether the pool has safety features, noted that the water was “clear,” and moved on to the water heater. That isn’t laziness. It’s the job description, and the job description says pools are somebody else’s problem.

What the home inspector checks, and what they don’t

Both big home inspector groups write their scope down, and both carve pools out of it.

InterNACHI’s home inspection Standards of Practice says the inspector is not required to inspect swimming pools or spas, and not required to determine the structural integrity or leakage of pools or spas. ASHI’s Standard of Practice lists “recreational facilities” as something the inspector isn’t required to inspect, and its glossary defines that term to include spas and swimming pools.

California adds one thing back. Business and Professions Code Section 7195 says a home inspection on a property with a pool or spa has to include a noninvasive look at which of the seven drowning prevention safety features are present, and the report has to say plainly if there are fewer than two. We went through the seven features, the fence measurements and what that report means for a sale in our post on California pool fence law. Short version: the inspector counts safety features and writes the count down. Nobody has to install anything because of that report, but a “fewer than two” line tends to show up in the repair request.

What a pool-specific inspection covers

A pool inspection is its own add-on, sometimes done by the same home inspector with pool training, sometimes by a separate pool inspector. InterNACHI publishes separate pool and spa inspection standards, and they’re worth reading before you hire anyone, because they tell you exactly where the inspection stops.

Under that standard the inspector looks at the water level, the interior surfaces, tile, coping, steps and ladders, the plumbing, valves, pumps, motors, drains, skimmers and filters, the heater, the visible electrical components including external bonding of pump motors, and the fencing, barriers and alarms. Angi’s inspection guide adds the lights, the timer and the main drain.

Now the part people skip. The same InterNACHI pool standard says the inspector is not required to find water leaks from the shell, test water chemistry, inspect underground pipes or valves, open or dismantle equipment, inspect heat exchangers, find stray voltage or defective bonding, or determine service life expectancy. ASHI’s pool standard excludes much the same: shell leaks, water chemistry, underground components, heat exchangers and life expectancy.

Pool inspection cost, and what gets added to it

Angi’s 2026 figure is an average of $140, with a range from $85 to $1,075 and professional inspections at $125 to $250. Its state breakdown puts California at $150 to $325. HomeGuide’s 2026 guide runs higher: $200 to $500, a $350 average, as little as $150 when it’s bundled with the home inspection, and up to $800 for a complicated pool. HomeGuide says most take one to two hours.

Bundling is the cheap route, as long as you know what the bundle covers. A $150 add-on that runs the pump for a minute and notes “heater present” is not the same product as a two-hour look with the equipment running.

Leak detection is separate and priced separately. HomeGuide and Angi both put leak detection on an inground pool at $400 to $1,000, and Angi’s average is $300 before any repair. A pressure test on the plumbing lines is $200 to $500 per Angi, $150 to $500 per HomeGuide. If a leak turns out to be under the deck, Angi puts excavation at $500 to $5,000.

Equipment age: read the data plates yourself

Inspectors aren’t required to tell you how many years a pump has left. You can get most of the way there with a phone camera.

Every pump, filter and heater has a label with a model and serial number, and the serial usually hides a date. Hayward’s own guide to reading its serial numbers says that on equipment built from May 2010 on, the fifth and sixth digits are the year and the seventh and eighth are the month. Other brands code it differently, but most code it somewhere.

Then compare against lifespans. Angi says pool pumps last 8 to 15 years, and gas and electric heaters 5 to 10. HomeGuide gives standard plaster 7 to 12 years. A pad where everything is 12 years old isn’t broken, it’s scheduled. And if the pump is an old single speed, its replacement has to meet California’s variable speed pump rule, so price the replacement that way.

Leaks: the bucket, the dye and the pressure test

You can’t see a pool leak on a one-hour walkthrough. You can see the evidence: a pool that’s low when the seller swears it was topped off, an autofill that runs constantly, wet soil near the pad that never dries, or a pump that keeps losing prime.

A pressure test is how a tech finds out whether the underground lines hold. Each line gets plugged and pressurized, and a line that won’t hold pressure is leaking somewhere under the deck. Our own leak detection process pressure tests each return, skimmer and drain line for the same reason.

Ventura County complicates this. The pool season here runs year round, so evaporation in August is real, and a seller can honestly believe a pool is “just evaporating.” A bucket test on the steps settles it for about the price of a bucket.

Plaster, drain covers and bonding

Plaster. Look for rough patches that snag a swimsuit, gray showing through, stains, and hollow spots that sound different when tapped. A pool freshly acid washed before the listing photographs beautifully and has less plaster than it did last month. Ask when it was last resurfaced, and see our post on when a pool needs resurfacing for the signs.

Drain covers. Covers wear out on a schedule, and most carry a service life stamped on top. Hayward’s 8 inch anti-vortex cover sells for $42.99 at Leslie’s and lists a 7 year service life. California’s Swimming Pool Safety Act requires any new pool or spa built under a permit to have anti-entrapment covers meeting the federally designated standard, plus dual drains or an alternative. An older pool may have neither, and a missing, cracked or expired cover is the cheapest serious problem on this list.

Bonding. NEC 680.26 requires equipotential bonding to reduce voltage gradients around a pool, using solid copper no smaller than 8 AWG, and it reaches pump motors and metal within 5 feet of the water, per EC&M’s summary of the 2023 code. At the pad that shows up as a bare copper wire clamped to the pump, heater and anything metal nearby. A cut or missing wire gets noted. A tingle in the water gets a licensed electrician before anybody swims.

The pool inspection checklist, with what red flags cost

This is the list to hand whoever inspects the pool. Costs are 2026 national figures from the sources named, so read them as a floor for coastal Southern California.

More detail on the pad items is in what pool equipment repair actually costs, and heaters get their own post on whether to repair or replace a pool heater.

Timing it inside your contingency

The standard California purchase agreement gives the buyer an investigation contingency that defaults to 17 days, per the law firm Garmo & Garmo’s summary. That sounds like plenty until a leak detection company can’t come until day 15. Book the pool inspection the same week as the home inspection, and schedule leak detection the moment anything points to a leak.

Ask the seller for pool service records too. HomeGuide notes that inspectors review maintenance records when they exist. A pool with three years of weekly service logs is a different purchase from one that was “maintained by the owner” (which usually means occasionally).

Questions buyers ask about pool inspections

Does a home inspection include the pool? Not really. InterNACHI and ASHI both exclude pools from the standard home inspection. In California the inspector still has to report the drowning prevention features under Section 7195.

Is the pool inspection cost worth it on an older pool? On an older pool it’s worth the most. One bad heater is $477 on average to repair per Angi, and a resurface averages $11,000. The inspection is a few hundred.

Can I ask the seller to fix what the inspection finds? You can ask for repairs or a credit during the contingency period. What the seller agrees to is between your agent and theirs.

What should I ask whoever inspects it? Whether they run the equipment, test the heater, pressure test the lines or refer that out, check drain cover dates, look at bonding, and give an age for each piece of equipment. Whatever they say no to, find someone who says yes.

Photograph the pad before you close

One thing to do this week: walk out to the equipment pad and photograph every data plate, the filter gauge with the pump running, and the drain cover if you can see it. That’s five minutes, and it turns a vague “pool looks fine” into model numbers and dates your inspector can check against the lifespans above.

Keep those photos after you close. When something on the pad needs work, send us the photos and the address. We service Pentair, Jandy, Zodiac, Hayward and Sta-Rite equipment, so the brand on that pad probably isn’t a mystery to us. Call (805) 586-2055.
