Full Breakdown
Home business signage in unincorporated Clark County is limited by CCC 40.260.100(D)(4). Only one sign related to the home business is allowed, and its size depends on location: no larger than 2 square feet inside an urban growth boundary, or no larger than 6 square feet in rural areas. If the sign is included with the home business permit application, a separate sign permit is not needed. Because home businesses must remain compatible with the residential neighborhood, illuminated, flashing, or off-premises signs are not part of the allowance. Incorporated cities set their own sign rules.
Violations & Fines
Oversized or additional signs violate the home business standards and can be cited under Clark County code enforcement, and may jeopardize the home business permit.
