Do I need a permit for a portable hot tub?
An electrical permit is usually required for the dedicated 240V circuit. A building permit may not be required for portable units sitting on a deck or patio that can already support the weight.
Can I put a hot tub on my deck?
Only if the deck is engineered to support the weight. A filled hot tub weighs 3,000-6,000 pounds. Many existing decks need reinforcement, which requires a building permit.
