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

Romeoville regulates rentals (long- and short-term) primarily through Chapter 156 (Residential Rental Property Licensing and Crime Free Housing) and the property maintenance standards in Chapter 151 (Property Maintenance Code). Section 156.04 requires every owner of a residential rental dwelling to hold an annual Residential Rental License; the Crime Free Housing program webpage and Section 156.04 set the fee at $75 per single-family dwelling unit (or $65 on renewal where the owner attends an online crime-free housing seminar) and $100 per multi-family building, with full enforcement that began January 1, 2017. Section 156.04 conditions issuance and renewal of the license on proof that the unit has been inspected and that a current and valid certificate of occupancy has been issued under Chapter 155. The binding occupancy figure for an Airbnb or Vrbo unit therefore comes from that certificate of occupancy and from the Chapter 151-adopted 2015 International Property Maintenance Code minimum sleeping-room floor area standard, not from a Romeoville-specific 'two persons per bedroom plus two' formula. Romeoville's bedroom definition in the Chapter 150 building amendments treats a bedroom as a conditioned room with four drywalled walls, a door and closet, used for sleeping, not less than seven feet in any horizontal dimension, not less than seventy square feet, and a ceiling height of not less than seven feet measured from the finished floor. Operators that meet the 35 ILCS 145 definition of a hotel operator (rentals for periods of less than 30 days) must also remit the Illinois Hotel Operators' Occupation Tax through the Department of Revenue, and effective July 1, 2025, hosting platforms that meet the 're-renters of hotel rooms' definition are also subject to that tax under FY 2025-28 guidance.
