For home-based businesses, the regulations are particularly strict:

• Maximum size of 6 square feet (or 2 square feet in some zones)
• Must be attached flat against the dwelling
• Limited to displaying only the occupant's name and occupation

Exterior Lighting Standards

Parking Area Illumination

When lighting parking areas, property owners must be mindful of neighboring properties:

• Any lighting used for off-street parking areas, including commercial parking lots, must be arranged to reflect light away from:
• Adjoining premises in residential ("R") districts
• Public rights-of-way

Preventing Light Nuisance

The county code addresses light pollution through home occupation regulations, which prohibit:

• Any home occupation that creates glare affecting neighboring properties
• Activities that are "noxious, offensive or hazardous" due to glare emissions

Site Plan Requirements

For new developments, lighting must be considered early in the planning process:
