Summary

Unincorporated Lake County's UDO sets no numeric residential light-trespass (foot-candle) limit. Its enforceable trespass-type controls are narrow: solar-farm lighting must be shielded and aimed downward, home occupations may not add commercial-like exterior lighting, and glare mitigation is a screening goal. Persistent glare onto a neighbor is generally a nuisance matter.

These county ordinances apply to unincorporated areas of Lake County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

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 fix a maximum light level at the property line for homes. Section 154-8-060 requires solar-farm operational lighting to be 'shielded away from nonparticipating adjacent properties and positioned downward... to minimize light emission onto adjacent properties.' The home-occupation standard (154-9-090.F.10) bars adding commercial-like exterior lighting that alters a lot's residential character, and the landscaping/screening article lists reducing 'the impacts of noise and glare' among its purposes (154-14-010.C). Beyond these, light spilling onto a neighbor is addressed as a nuisance rather than by a specific trespass metric, and incorporated municipalities set their own lighting codes for most of the county.

Violations & Fines

Where the UDO's lighting standards apply, violations follow the 15-day cure notice and citation penalties up to $2,500 (first) and $7,500 (subsequent) under IC 36-1-3-8; broader glare disputes may be pursued as nuisance.

Frequently Asked Questions

Is my neighbor's floodlight shining on my house a code violation?
Not under a specific county trespass limit for homes. It is generally addressed as a nuisance, or under a city/town lighting code if you are inside an incorporated area.
Do any county rules limit light spilling onto neighbors?
Yes for certain uses: solar farms must shield and aim lighting downward, and home occupations may not add commercial-like exterior lighting affecting neighbors.
