Key takeaways
A pool or hot tub is the amenity a listing charges for and the amenity most likely to be found out of compliance. Routine upkeep is inexpensive and predictable, $236 a visit for a pool and $600 a year for a hot tub. What the CDC's inspection data adds is the failure rate: four in five public aquatic inspections find a violation, one in eight pools and one in seven hot tubs is shut on the spot, and hot tubs fail slightly more often than pools. For a rental, the water is either right or the amenity is off the listing.
1 in 8 public pool inspections and 1 in 7 hot tub inspections end in immediate closure
Almost 80% of public pool and spa inspections find at least one violation
Pool maintenance costs $236 a visit on average, in a normal range of $116 to $357
Hot tub maintenance costs $600 a year on average, in a normal range of $240 to $940
Annual pool upkeep runs $800 to $3,000 depending on size
Pool chemical injuries send about 4,500 people to the emergency department a year
How often an inspection closes the pool
The CDC runs the only national surveillance of pool and spa inspections, through its Network for Aquatic Facility Inspection Surveillance. According to the US Centers for Disease Control and Prevention (cdc.gov), from 84,187 routine inspections of 48,632 public aquatic venues in Arizona, California, Florida, New York and Texas in 2013:

How we built this report
Every figure below was compiled in August 2026 from named public sources and checked against the original document before publishing.
- Compiled from primary sources
Two published contractor pricing guides from the same publisher for comparable pricing, and the federal public-health agency's inspection surveillance summary, its fact sheet and its press release on that data.
- Only explicitly stated figures
We include only numbers a named source states directly, and attribute each one inline where it appears. Where we do arithmetic on top of a cited figure it is labelled as a worked example with the inputs shown.
- Vintage and provenance stated
The CDC inspection data is from 2013, the most recent national surveillance analysis published; the pricing guides were updated March and August 2026. Both Angi guides used here are marked by Angi as produced with automation and editor-reviewed; we cite only their stated figures.
- Independent review
Written by one co-founder, reviewed by the other before publishing.
Scope caveat: contractor cost figures are guide-level national ranges, not an audited survey, and vary by market, pool size and season. The CDC data covers public aquatic venues in five states; a rental pool or hot tub is typically regulated as public or semi-public but the surveillance does not identify rentals separately. This page covers recurring maintenance and inspection only. Hot tub repair pricing, damage claims and liability law are covered in our outdoor amenity damage guide and hot tub liability guide and are not repeated here.

What pool maintenance costs
According to Angi (angi.com), whose pool maintenance guide was updated in March 2026, a pool maintenance visit costs $236 on average, in a normal range of $116 to $357, with a low of $55 and a high of $780. Routine cleaning, skimming, brushing and vacuuming, is $80 to $150 a visit; chemical balancing $15 to $35; an equipment check $75 to $150; a seasonal opening or closing $200 to $400; and a deep clean or acid wash $250 to $500. Labor runs $75 to $150 an hour, and some services price by area at $1.50 to $2.50 per square foot a year.

Statistic 11
In-ground pools cost more to maintain than above-ground or indoor pools; saltwater pools need salt cell replacement and system checks.
Angi (2026)
Worked example
Weekly service through a 20-week season at Angi's $236 average is $4,720, plus $400 to $800 for opening and closing, per RapidEye Research. At the routine-cleaning-only rate of $80 to $150 a visit, the same 20 weeks is $1,600 to $3,000. The gap between those two figures is chemicals, equipment checks and the occasional deep clean, which is where a rental pool, used harder than a home pool, tends to land.
What this means: the per-visit average understates a rental's true cost, because Angi's own guidance is that weekly service is standard for an active pool and a rental in season is active every week. Chemical balancing at $15 to $35 is the cheapest line item on the list and, per the CDC data below, the one whose absence most often closes the pool.
What a pool costs per year
According to Angi (angi.com), annual pool maintenance scales with volume: $800 to $1,200 a year for a small pool under 10,000 gallons, $1,200 to $1,800 for a medium pool of 10,000 to 20,000 gallons, and $1,800 to $3,000 for a large pool over 20,000 gallons. Weekly service is common for active pools; monthly or biweekly service is cheaper but allows more buildup. Concrete pools need more frequent brushing and fiberglass pools less chemical treatment, so material moves the annual figure as well as size.

Angi (2026)
Statistic 16
Concrete pools need more frequent brushing; fiberglass pools need less chemical treatment.
Angi (2026)
Statistic 17
Larger pools require more chemicals, longer cleaning and cause more equipment wear, raising both per-visit and annual cost.
Angi (2026)
Worked example
At Angi's per-area rate of $1.50 to $2.50 per square foot a year, a 15-by-30-foot pool, 450 square feet, is $675 to $1,125 a year, per RapidEye Research, which lands inside Angi's $800 to $1,200 small-pool band and cross-checks the two pricing methods against each other.
What this means: the annual number is a homeowner's number. Angi's own hot tub guide notes vacation rentals may need more frequent service; the same logic applies to a rental pool, where every changeover is a new set of swimmers and the water has no off-week. Budget from the weekly figure, not the annual band.
What a hot tub costs
According to Angi (angi.com), whose hot tub maintenance guide was updated in August 2026, hot tub maintenance costs $600 a year on average, in a normal range of $240 to $940, with a low of $200 and a high of $2,400, or $20 to $75 a month. Professional service runs $75 to $150 an hour; a filter $20 to $60; a replacement cover $300 to $800; winterizing $200 to $500. Angi states directly that heavy users or vacation rentals may need more frequent service, and that daily use means more chemicals, faster filter replacement and possibly more frequent professional visits.

Statistic 22
Heavy users or vacation rentals may need more frequent service; daily use means more chemicals, faster filter replacement and possibly more frequent professional visits.
Angi (2026)
Statistic 23
Larger tubs need more chemicals, more water and more heating energy, raising annual cost with seats and gallons.
Angi (2026)
Statistic 24
Saltwater systems cost more upfront but reduce some chemical need; traditional chlorine tubs need regular balancing; inflatable tubs cost less to maintain but may need more repairs.
Angi (2026)
Statistic 25
Regular maintenance means weekly water testing, monthly deep cleaning and periodic filter changes; wood tubs need periodic sealing and are vulnerable to rot.
Angi (2026)
Worked example
A rental hot tub on Angi's top-of-range $940 a year plus $200 to $500 winterizing is $1,140 to $1,440 a year, and $1,440 to $2,240 in a year that also needs a $300 to $800 cover, per RapidEye Research. On a listing that adds a hot tub premium of even $15 a night at 200 nights, $3,000, the amenity covers its own upkeep even in a cover year, provided the water passes.
What this means: a hot tub is cheap to run and expensive to run badly. Its consumables are small and its labor rate matches a pool's, but the CDC data below shows it fails inspection slightly more often than a pool does, and Angi's own text singles out vacation rentals as the heavy-use case. The operational reading is that a hot tub's water needs checking at every changeover, not on a monthly schedule.
How often inspections find a violation
According to the US Centers for Disease Control and Prevention (cdc.gov), whose Network for Aquatic Facility Inspection Surveillance analysed 84,187 routine inspections of 48,632 public aquatic venues in Arizona, California, Florida, New York and Texas in 2013, almost 80 percent of inspections identified at least one violation. Of the 66,098 inspection records with closure data, 12.3 percent, or 8,118, resulted in immediate closure. The most common violations were improper pH at 15 percent, safety equipment at 13 percent and disinfectant concentration at 12 percent. In the detailed data, disinfectant concentration violations appeared in 11.9 percent of inspections, safety equipment violations in 12.7 percent and pool chemical safety violations in 4.6 percent.

Statistic 32
Disinfectant concentration violations, a risk for infectious outbreaks, appeared in 11.9 percent of inspections (7,662 of 64,580).
US Centers for Disease Control and Prevention (2013 data, published 2016)
Statistic 33
Safety equipment violations, a risk for drowning, appeared in 12.7 percent of inspections (7,845 of 61,648).
US Centers for Disease Control and Prevention (2013 data, published 2016)
Statistic 34
Pool chemical safety violations appeared in 4.6 percent of inspections (471 of 10,264).
US Centers for Disease Control and Prevention (2013 data, published 2016)
Worked example
Angi prices chemical balancing at $15 to $35 a visit. The CDC finds pH and disinfectant violations in 15 and 12 percent of inspections and names them among the top three reasons a pool is found in violation. The single cheapest line item in the maintenance table is the one that most often fails the inspection, per RapidEye Research. A weekly $15 to $35 test through a 20-week season is $300 to $700 against an amenity that otherwise comes off the listing.
What this means: the failure rate is not an edge case; four in five inspections find something and one in eight closes the pool outright. Hot tubs fail slightly more often than pools, which tracks Angi's note that they are the heavy-use amenity in a rental. The two most common failures, pH and disinfectant, are chemistry, which is to say they are invisible at a walkthrough and only found by testing.
Why the water is a safety line, not a comfort line
According to the US Centers for Disease Control and Prevention (cdc.gov), pool chemical injuries account for about 4,500 emergency department visits each year, at least a third in patients under 18. Over 200 disease outbreaks were linked to pools, hot tubs and splash pads in 2015 to 2019. More children aged 1 to 4 die from drowning than from any other cause, and for ages 5 to 14 drowning is the second leading cause of unintentional injury death after motor vehicle crashes. The CDC's Model Aquatic Health Code, released in 2014, is the voluntary national standard jurisdictions adopt to minimise those risks, and it is the reference the inspection data is scored against.

What this means: for a rental, the pool or hot tub is the amenity with the highest guest value and the only one whose failure mode is a public-health event. That is why the maintenance figures on this page are best read against the CDC figures rather than on their own: $15 to $35 for a chemical check is not a maintenance cost, it is the price of keeping the amenity on the listing. Our hot tub liability guide covers what happens when it is not.
