Hot tub installations in Lake County require an electrical permit for the 240V circuit and must comply with barrier rules unless a locked ASTM F1346 safety cover is in place. GFCI and bonding mandatory per Illinois adopted NEC.
Lake County Building & Zoning Department requires an electrical permit for any hot tub or spa installation involving a dedicated 240V circuit, under the adopted 2017 National Electrical Code (NEC 680). GFCI protection, equipotential bonding of the spa shell and nearby metal parts, and an emergency shutoff within 5-10 feet (but at least 5 feet from the water) are mandatory. Illinois Plumbing Code 77 Ill. Adm. Code 890 may apply if plumbing connections are involved. Setbacks from property lines follow UDO accessory-structure rules (typically 5-10 feet). A lockable safety cover meeting ASTM F1346 typically satisfies barrier requirements in lieu of a fence for spas and hot tubs. If installed on a deck or elevated structure, verify load capacity; a 6-person hot tub can weigh over 5,000 lbs full. Indoor installations require proper ventilation and dehumidification. Drainage must discharge to pervious ground, never to storm sewers or neighboring lots.
Unpermitted 240V wiring: stop-work order, re-inspection fees $100 to $300, required correction. Improper drainage: WDO remediation orders. Missing safety cover when required: $150 to $500 fines. Electrical safety violations can result in insurance denial.
