Hot tubs in Atlanta: permits, power cost and draining

Key facts

Sources: City of Atlanta Work Exempt from a Permit; ATL311, Swimming Pool Permits (Construction), modified May 20, 2026; Georgia Power Residential Service R 31; Georgia Power Time of Use, Overnight Advantage; Georgia Power TOU-REO (Nights and Weekends); Atlanta Department of Watershed Management; ATL311, sewer cleanout location. All checked October 25, 2026.

Step 1: figure out which permits your spa triggers

Atlanta's Office of Buildings publishes a Work Exempt from a Permit list under Ordinance 17-0-1307. For electrical work at one and two family homes, it exempts only repair or replacement of existing outlets and fixtures and low voltage systems such as alarms. A new 240 volt, 40 amp circuit, the supply DreamMaker specifies for its Crossover 740, is new wiring and needs an electrical permit. A 120 volt plug and play spa such as the DreamMaker Cabana 2500 or the AquaRest Discover Premium 600 can skip new wiring only if a suitable GFCI protected outdoor receptacle already exists; adding one is new work, not a repair. The list's general repair exemption under $10,000 covers repairs, not new installations.

The swimming pool permit is the second track. ATL311's swimming pool permit article says residential pool permits need architectural, structural and site plans submitted to the Office of Buildings through Accela Citizen. The homeowner may submit if those plans are stamped and sealed; otherwise the contractor must. An in ground or built in spa clearly belongs here. The article does not say whether a portable, above ground spa set on a pad counts as a pool, and we will not guess, so ask the Residential Permits Division at residential-oob@atlantaga.gov or 404-330-6906 with the model before you pour a pad.

Step 2: check for trees and historic districts

Two Atlanta specific rules catch spa projects that would sail through elsewhere. First, since June 25, 2025, Ordinance 25-O-1341 requires every applicant whose project may affect trees to schedule and complete an arborist meeting with the Office of Buildings' Arborist Plan Review staff before submitting a permit application. Digging a trench for a spa circuit across a root zone, or pouring a slab under a canopy, is the kind of work that can affect trees. Contact Arborist.dpcd@atlantaga.gov or 404-330-6874. Second, the exempt work list says none of its exemptions apply to exterior work in a landmark or historic district governed by Chapter 20 of the zoning ordinance, except repair work under $2,500. If your home is in a designated district, a spa that changes the site needs city review.

Step 3: pick the right Georgia Power plan

Hot tub heating is flexible: a programmable spa can do most of its heating when power is cheapest. Georgia Power's three residential options, all with a basic service charge of $0.4603 a day and all with fuel and other riders added on the bill, price that flexibility very differently. Base energy, from bills rendered in June 2026:

On Overnight Advantage, all other hours (7 a.m. to 11 p.m. outside the summer weekday peak) are 10.3598 cents. Independence Day and Labor Day are off peak on both time of use plans. Both carry a twelve month initial contract term, after which you may change plans.

Worked example: one tub, three plans

Assume a tub that uses 6 kWh a day, 180 kWh a month. That is our planning figure, not a measured one; your use depends on the tub, the cover, how often you soak, and the weather. NOAA normals put Atlanta's average January low at 36.4°F, so winter use runs higher than summer. Base energy only, before riders:

• R 31, October to May: 180 kWh at 8.2116 cents is about $14.78 a month.
• R 31, June to September: about $15.79 if your home stays within the first 650 kWh, $26.23 in the 14.5738 cent tier, or $27.15 above 1,000 kWh. Last summer's bills will tell you which tier your home reaches, and the tub's kWh are billed at that tier.
• Overnight Advantage, all heating from 11 p.m. to 7 a.m.: about $4.01 a month. If it heats during the day outside the peak instead, about $18.65.
• Any heating in the summer weekday peak: 30.3495 cents, about $1.21 for each hour a 4 kW heater runs.

The tub alone makes Overnight Advantage look easy. The decision is really about the whole house: every kWh your air conditioner uses from 2 to 7 p.m. on summer weekdays is billed at 30.3495 cents base. Households that can pre cool before 2 p.m., or that already shift laundry and EV charging to night, benefit most. Households that run air conditioning hard on summer afternoons may pay more overall. Compare a year of your own bills before switching, since the term is twelve months.

Step 4: drain it the Atlanta way

Atlanta's Department of Watershed Management says chlorinated pool water must go to the sanitary sewer, or be held until chlorine and temperature are acceptable and then spread on a permeable surface. Storm drains, ditches and streams are prohibited. ATL311 explains that the sewer cleanout is usually near the front of the home, under the basement floor where the drain exits, or outside under the soil for homes built within the last 45 years. A submersible pump and a hose to the cleanout is the usual method for a 240 gallon spa. If you spread water on the lawn instead, stop adding sanitizer ahead of time, let the water cool, and drain slowly so it soaks in rather than running to the street. Atlanta averages 50.4 inches of precipitation a year, so pick a dry day.

Checklist before delivery

1. Ask the Residential Permits Division (404-330-6906) whether your spa needs the pool permit, and line up stamped plans if it does and you want to apply yourself.
2. If the pad or trench may affect trees, book the arborist meeting first (404-330-6874).
3. Check whether your home is in a Chapter 20 historic district.
4. Hire a licensed electrician for any new circuit and confirm the electrical permit is pulled.
5. Decide on R 31, Overnight Advantage or Nights and Weekends using a year of your own bills, then set the spa's heat schedule to match.
6. Find your sewer cleanout before the first drain.

Yes, if the architectural, structural and site plans are stamped and sealed. If they are not, the contractor must submit the application, per ATL311's swimming pool permit article. Applications go through Accela Citizen online.
