Summary
Unincorporated Lake County's UDO has no general residential dark-sky ordinance. The only codified downward-shielding standard applies to solar farms, which must shield operational lighting away from adjacent properties and aim it downward. For homes, standards come from your city or town; the county limits commercial-style lighting on home occupations.
Any onsite lighting provided for the operational phase of the solar farm must be shielded away from nonparticipating adjacent properties and positioned downward to the extent possible to minimize light emission onto adjacent properties.
Full Breakdown
The Lake County UDO does not impose a countywide dark-sky or full-cutoff standard on ordinary homes. Its clearest shielding rule is in section 154-8-060 for solar farms, which must direct operational lighting downward and shield it from neighbors. The home-occupation rules (154-9-090.F.10) prohibit 'the addition of commercial-like exterior lighting' that changes a lot's residential character, and wind turbines and aircraft-related uses may only be lit as the FAA requires. Sign lighting must be constant, and search/strobe/flashing lights visible from the right-of-way are prohibited (154-15-020). Residents in incorporated cities and towns (Crown Point, Gary, Hammond, Merrillville, etc.) should check municipal lighting codes, which govern most Lake County land.
Violations & Fines
Where a UDO lighting standard applies (e.g., solar farms, home occupations), violations follow the 15-day cure notice and citation penalties up to $2,500 first / $7,500 subsequent under IC 36-1-3-8.
