Johnson County and its cities require an electrical permit for a hot tub or spa's 240-volt circuit. A locking, listed safety cover can satisfy the barrier rule in place of a full pool fence.
A hot tub or spa in unincorporated Johnson County and in Iowa City, Coralville, and North Liberty usually needs an electrical permit for its 240-volt, GFCI-protected circuit, plus a building permit when a deck or structural support is involved. The unit must meet zoning setbacks from property lines. A lockable safety cover meeting the ASTM standard can serve as the barrier for a spa, so a full pool fence is not always required. Drainage cannot discharge onto a neighbor's property or into a storm drain. An elevated or rooftop deck installation may need a structural load check for the filled weight.
Wiring a spa without the electrical permit fails inspection and must be corrected. Draining onto a neighbor's lot or into a storm drain requires remediation.
