Summary
Home-based businesses in unincorporated McHenry County may see clients on-site, but UDO §16.56.050(I)(5) requires every visit to be scheduled by appointment only. Combined with the hour restriction on business transactions and the ban on any activity perceivable beyond the lot line, the rule keeps client traffic predictable rather than capping visits at a fixed daily number.
I. Home Occupations.
3. The operator of a home occupation must be a resident of the dwelling unit.
4. No more than one (1) person other than a member(s) of the household residing on the property may be working on-site at any one time. If the home occupation includes a dispatch component, employees to be dispatched are not to wait assignment or be dispatched from the property.
5. For home occupations where clients visit the premises, the home occupation shall schedule all visits by appointment only.
8. No deliveries or any other transactions of business within the residence, except emergency service, can be made between the hours of 10:00 p.m. and 7:00 a.m.

Full Breakdown
McHenry County does not cap the number of clients a home occupation can see in a day or week, but it does control how they arrive. 050(I)(5) requires that for home occupations where clients visit the premises, the home occupation shall schedule all visits by appointment only, which rules out walk-in retail traffic, drop-in hours, or a storefront-style open-door policy at a residence. That scheduling requirement sits alongside the section's broader nuisance controls: subsection (I)(7) bars any offensive noise, vibration, smoke, dust, odor, heat, glare, or electrical disturbance perceivable at or beyond the lot lines, which in practice limits how many cars, how much idling, or how much foot traffic a client-facing home business can generate without drawing a complaint.
except for emergency service calls. Because the operator must also be a resident of the dwelling under subsection (I)(3) and only one non-household worker may be on-site at a time under (I)(4), a home occupation cannot scale into a staffed office with a waiting room; appointment-only scheduling is the mechanism the county uses to keep client volume compatible with a residential street rather than setting a numeric ceiling.
Violations & Fines
A home occupation that advertises walk-in hours, posts a sign inviting drop-in customers, or otherwise allows clients to visit without a scheduled appointment is out of compliance with §16.56.050(I)(5) and can be cited by the Zoning Enforcement Officer as a zoning violation; because home occupations must be disclosed in any conditional use permit for the property, repeated appointment-rule violations can support added conditions or revocation of that approval.
