Summary

In unincorporated McHenry County, a furnished home may be rented short-term up to 12 rental periods or 90 days a year by right; exceeding those limits requires a conditional use permit. Cities like Crystal Lake and Woodstock require their own permits.

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

Vacation Rental. Dwelling units, or portions thereof, that are offered as vacation rentals for more than twelve (12) rentals per calendar year or more than ninety (90) days per calendar year shall obtain a conditional use permit prior to occupancy.

Full Breakdown

The McHenry County Unified Development Ordinance regulates "Vacation Rentals" in unincorporated areas. They are allowed by right in agricultural, residential, and B-1 zoning districts up to the annual caps; a Vacation Rental exceeding 12 rentals or 90 days per year must obtain a conditional use permit before occupancy under UDO §16.56.030.VV. Incorporated municipalities set stricter rules: Crystal Lake requires a limited-use permit for a "tourist home," and Woodstock requires a bed-and-breakfast special use permit or a short-term rental certificate plus a home-occupation license.

Violations & Fines

Operating an unincorporated vacation rental beyond the by-right caps without a conditional use permit is a UDO zoning violation subject to enforcement and daily fines. Woodstock STR certificate violations carry escalating fines of $500, $750, then $1,000.

Frequently Asked Questions

Do I need a permit to Airbnb my rural McHenry County home?
Not if you stay within 12 rental periods and 90 days per year in an allowed zoning district. Exceed either limit and you must obtain a conditional use permit first.
Are STR permits handled by the county or my city?
If your property is inside a city or village, that municipality's code controls. The county UDO applies only to unincorporated land outside municipal boundaries.
