Will County, IL Short-Term Rentals: Occupancy Limits (2026)

Section 155-9.30 governs bed and breakfast establishments, the county's zoning category for a house where the owner offers overnight lodging and meals to paying guests, and it is the only use classification in the code built around short-stay lodging inside a residential structure. Subsection (A) limits the operation to no more than four guest rooms and caps occupancy at two adults per guest room, meaning an operator can host a maximum of eight paying adult guests at any one time regardless of the size of the house. Subsection (B) separately limits how long any one guest can stay: no more than ten consecutive days, which prevents an operator from using the bed-and-breakfast classification to run what is functionally a month-to-month rental.

The same section layers on operating conditions that affect how the rooms can be marketed and accessed: a single non-illuminated wall sign of no more than two square feet is allowed (§ 155-9.30(C)), no guest parking may be located in the street yard (§ 155-9.30(D)), and tandem parking spaces are capped at two spaces deep (§ 155-9.30(E)). Because bed and breakfasts are allowed only by special use permit in the A-1, A-2, E-1 and E-2 districts under the § 155-7.30 use table, and are prohibited outright in every R, C, I and SP-PO district, an operator cannot rely on the occupancy cap alone; the room and guest limits apply on top of, not instead of, the district-level restriction on where the use is allowed at all.
