Hot tubs or whirlpools are considered the same as swimming pools under the Alberta Building Code where safety regulations are applied when the depth of water is greater than 600 mm (24 inches).
Permanent hot tubs and whirlpools require both a development permit and a building permit regardless of whether they are stand alone or built into a deck. Temporary hot tubs and whirlpools do not usually require a development permit but may still require a building permit.
Any mechanical work involved in the installation of the hot tub will require separate mechanical permits since mechanical work is not included in the building permit. (See Electrical, Plumbing and Gas for more information).
