Mount Prospect, IL Rental Inspections: Inspection Programs (2026)

Section 23.1816 of the Mount Prospect Village Code is the inspection engine behind the rental license. A multi-family rental structure is a building with three (3) or more dwelling units, of which at least fifty percent (50%) are rental units. Each such structure and each unit within it is subject to inspection for compliance with all applicable regulations. A license can be denied if an inspection finds noncompliance or outstanding fees or judgments exist, and in that case the licensee can apply for a conditional license.

Initial and subsequent annual licensing inspections run on a regular schedule and include the building exterior, common areas, basement and not less than twenty percent (20%) of the individual dwelling units. All units in the structure are inspected every five (5) years unless the incentive provisions call for less. A multi-family structure under ten (10) years old is not subject to individual unit inspections unless there is reasonable suspicion that a violation exists, and its age is fixed by the original certificate of occupancy.

An owner can elect inspections on an "as vacant" basis, which requires giving the Village two (2) weeks' advance notice before a vacant unit is reoccupied. Ordinary inspections come with at least thirty (30) days' notice by regular mail, and the owner must give each tenant notice of the date and time at least seventy two (72) hours ahead. Those notices tell owners and occupants of their right to refuse consent and require the Village to obtain an administrative search warrant.

A clean record earns lighter inspections. An inspection group with twelve (12) or fewer units has individual unit inspections waived for the following license year. A group with thirteen (13) to nineteen (19) units has one unit inspected, and a group with twenty (20) or more units has five percent (5%) of units inspected. If a unit is found unfit for human occupancy, an additional twenty percent (20%) of units is inspected, at the Appendix A fee of $50.00 per unit.
