How does an HOA board run a hot tub or spa at the community pool?

By OurHOA · General information · Revised October 25, 2026

How an HOA board runs a community hot tub or spa: TX, FL and CO spa rules, chlorine and test schedule, the 104 F limit, required signs, draining and owner rules.

Part of the HOA board handbook: vendors, projects and upkeep.

The short answer

Run the spa as its own body of water with its own log, not as a corner of the pool. A few hundred gallons of hot water with eight people in it loses chlorine fast and grows bacteria fast, so it needs more testing, a higher disinfectant level and regular draining. Five things matter most. Know which agency regulates it. Keep chlorine or bromine in range and write down every test. Hold the water at or below 104 degrees Fahrenheit and check that with a thermometer, not the heater dial. Post the required signs and make sure the emergency shutoff and phone work. Drain and scrub it on a schedule you can defend. Spa rules come from your state, your city or county and your own governing documents, and they differ. Use this guide as a working outline, not legal advice, and ask your health department which code it enforces at your address.

Find out who regulates your spa

Texas regulates HOA spas directly. The state pool and spa rules in 25 TAC chapter 265, subchapter L, define a Class C spa as one open to members and their guests but not the general public, and they name property owner associations in that definition (265.182). Section 265.194(b) requires every Class C spa to be maintained under the supervision of a trained and certified operator, though that person does not have to be on site. Many Texas cities run their own permit and inspection programs on top of the state rules. Florida draws a line at 32. Under section 514.0115(3), pools serving homeowners associations of no more than 32 units or parcels are exempt from state supervision except for water quality and the anti-entrapment rules in 514.0315. A larger Florida association should assume the spa is a public pool under chapter 514, needs a Department of Health operating permit, and must follow rule chapter 64E-9. Colorado's state rule, 5 CCR 1003-5, counts a spa or hot tub as a pool and exempts private pools, meaning pools tied to single-family homes, condominiums or apartments and used only by residents and their guests. A residents-only HOA spa usually fits that reading. County health agencies can still adopt their own rules, so call yours and put the answer in the pool file.

Chemistry and how often to test

Texas sets separate spa numbers in Figure 25 TAC 265.193(c): free chlorine at least 2.0 ppm with 3.0 ideal and 8.0 maximum, or bromine at least 4.0 ppm with 5.0 ideal and 10.0 maximum, and pH from 7.0 to 7.8. A Class C spa with no staff on site must be tested for disinfectant and pH at least once a day and the results logged (265.193(o)(3)). Alkalinity, calcium hardness and balance get tested at least every 10 days, and the logs are kept for three years (265.193(o)(4)-(5)). Florida rule 64E-9.004 sets free chlorine for spa-type pools at 2 to 5 mg/L and caps cyanuric acid in spas at 40 mg/L. Rule 64E-9.008(12) requires automated ORP and pH controllers with sensing probes on spa pools. CDC's Legionella control toolkit for hot tubs recommends free chlorine of 3 to 10 ppm or bromine of 4 to 8 ppm, pH of 7.2 to 7.8, and testing at least twice a day, hourly under heavy use. It also says not to use cyanuric acid or stabilized chlorine in hot tubs because they slow disinfection. In practice: follow your state's numbers as the legal floor and CDC's as the target. A Florida spa can't go above 5 mg/L, so aim for 3 to 5 there. Test twice a day if anyone can do it, even where once is the legal minimum. Keep dichlor and trichlor tablets out of the spa entirely. Texas already bans cyanuric acid and stabilized chlorine in indoor spas (265.193(d)).

Temperature, signs and the shutoff

The 104 degree number shows up everywhere. Florida rule 64E-9.008(8) caps heated pools at 104 degrees Fahrenheit and requires a working in-line thermometer. Colorado's water quality table lists 104 as the maximum for spas. Texas puts it on a sign. Heater thermostats drift, so check the water with a floating or in-line thermometer at every chemistry test and log the reading. Texas publishes the spa sign list in Figure 25 TAC 265.190(h)(4). It applies to spas built under the current rules and to any spa sign you replace. It calls for 'WARNING - NO LIFEGUARD ON DUTY' in 4-inch letters where no lifeguard is provided, 'DO NOT USE THE SPA IF THE WATER TEMPERATURE IS ABOVE 104 DEGREES FAHRENHEIT' and the maximum user load in letters at least 1 inch high, and these in letters at least 2 inches high: the location of the nearest emergency phone, EMERGENCY SPA SHUTOFF, the 2-week diarrhea warning, 'PERSONS UNDER THE AGE OF 14 MUST NOT BE IN THE SPA WITHOUT ADULT SUPERVISION' and 'PETS IN THE SPA ARE PROHIBITED.' Florida leaves spa signs to the local building department (64E-9.008(12)(c)), so ask it for the list. Texas also requires an emergency phone or monitoring device within 200 feet of the water that works whenever the spa is open (265.190(i)). Section 265.191(c) says lifeguards are not required at spas. Press the emergency shutoff button once a month with the service tech watching, and confirm the pumps and jets actually stop.

Drain, scrub and filter on a schedule

CDC gives a formula for how often to replace hot tub water: days between drains equals the spa's volume in gallons divided by 3, then divided by the average number of users per day. A 600-gallon spa with 12 users a day works out to about 17 days. Use your busiest month's numbers, round down, and put the dates on the board calendar. Each time it's drained, scrub every surface hard. Bacteria build a slime layer called biofilm in hot water, and draining alone won't remove it. Keep water moving across the filter 24 hours a day. Backwash sand filters on the service company's schedule, and if you have cartridge filters, keep a spare set so one can be cleaned and dried while the other runs. The drains need the same care as the pool's. Texas requires the drain cover documentation to stay on site or be produced within five business days (265.194(e)). In Florida, rule 64E-9.017 lets the department close a pool when any part of the anti-entrapment system or a drain cover is missing, loose or damaged. Spa drain covers have expiration dates, so read them every spring. If someone has a fecal accident in a Florida spa, rule 64E-9.008(12)(d) allows draining it and disinfecting the spa, filter and plumbing instead of treating the water in place.

Rules owners will read

Keep the spa rules to one sign and one page, and make them match the required signs. Rules most HOA spas use: posted maximum number of people; children under 14 only with an adult in the spa area; no glass; no pets; no oils, lotions or bath products in the water, which Florida bans outright in spa pools (64E-9.008(12)(a)); shower before entering; and closing time the same as the pool. A suggested time limit and a general health caution can go on the sign as advice, not as rules the board will try to enforce. Adopt new rules through your normal rule process and notice. Our guide on HOA community pool rules and guest policies covers how pool rules usually read. Wording for the owner notice: 'The spa reopens Saturday at 10 a.m. Water is kept at or below 104 degrees and tested twice a day; the log is posted inside the equipment room door. Children under 14 must have an adult with them in the spa. No glass, pets, oils or lotions. If the water is cloudy, smells strongly of chlorine, or the jets won't stop, get out, press the emergency shutoff and call or text [name] at [number].'

A sample routine

Every morning: test disinfectant and pH, read the thermometer, check that the shutoff and phone signs are in place, and log all three numbers. Every evening, where a volunteer or controller can cover it: a second disinfectant and pH test. Weekly: compare the controller readings to a manual test kit, check the cover and lid straps, and clean the waterline. Every 10 days in Texas, and a good habit elsewhere: alkalinity, calcium hardness and balance. At each scheduled drain: scrub, clean or swap the filter, inspect the drain covers and refill. Monthly: press the emergency shutoff. Each spring: read the drain cover expiration dates, have the heater serviced, and replace faded signs. Each fall: decide whether the spa runs through winter or shuts down with the pool. A spa left running all winter still needs its daily test, and unattended winter months are when logs go blank.

Mistakes boards make with spas

Putting the same tablets in the spa that go in the pool. Trusting the heater setting instead of a thermometer. Testing the spa only on the service tech's visit days. Draining it when somebody complains about the smell instead of on a calendar. Leaving the spa open while the pool is closed for cold weather, with nobody checking it. Not knowing which button is the emergency shutoff. Fix the authority question before the season starts, with a motion for the minutes: 'Moved that the pool lead director and the contracted certified operator may each close the spa immediately for water chemistry, temperature, equipment or safety reasons, may drain and refill it outside the regular schedule, and will report to the board at its next meeting.' For the full checklist that runs before opening day, see our guide on how to open an HOA pool for the season, and if an inspector does close the spa, our guide on what to do when the health department closes the HOA pool walks through reopening.
