Summary

O'Fallon requires every rental dwelling to pass a Code Official inspection and hold a valid occupancy permit before anyone moves in. Chapter 525 lets the Code Official inspect units and common areas against the city's Property Maintenance Code health and safety standards, and occupying a rental without that permit is unlawful.

The Code Official is hereby authorized to make inspections of all rental dwelling units within the City of O'Fallon for the purpose of carrying out and enforcing the requirements and standards of this Chapter and to determine whether dwelling units and common areas, if any, conform to the health and safety requirements of the Property Maintenance Code of the City in force at the time of the inspection.

The city can revoke an existing permit under Section 525.090 for false statements, unabated nuisances, condemned structures or overcrowding, and delinquent-applicant restrictions in Section 100.012 apply to rental owners too.

Frequently Asked Questions

Does O'Fallon inspect rental homes before tenants move in?
Yes. Section 525.030 lets the Code Official inspect every rental dwelling unit and common area, and Section 525.040 makes it unlawful for an owner or tenant to occupy the unit until that inspection is complete and the Code Official has issued a rental occupancy permit.
How long does an O'Fallon rental occupancy permit last?
An approved property maintenance inspection is valid for twelve months under Section 525.060. After that period, the rental needs a new inspection and permit before the owner can keep leasing the unit to tenants.
What heat must a landlord provide in O'Fallon?
Section 602.3 of the adopted Property Maintenance Code requires owners renting out dwelling units to supply heat that keeps habitable rooms, bathrooms and toilet rooms at a minimum of 68 degrees Fahrenheit every day of the year, with a lower 65-degree standard allowed only when the average monthly outdoor temperature exceeds 30 degrees.
