St. Louis County, MO Rental Inspections: Inspection Programs (2026)

Chapter 825 SLCRO licenses every residential rental property in unincorporated St. Louis County, and the license only stays valid if the property keeps passing muster under Chapter 1110, the Property Maintenance Code. Section 825.400 gives the Director five separate grounds to suspend or revoke: the property is found out of compliance with Chapter 1110 and isn't fixed within 30 days of the notice of non-compliance (a window the Director can extend if the owner is moving forward as expeditiously as possible); the owner made material false statements on the license application or an exemption declaration; the owner is delinquent on rental property maintenance fines owed to the St. Louis County Municipal Court; the owner racks up more than two suspensions in any 12-month period, which converts to a revocation; or the owner never obtained the required occupancy, re-occupancy, or pre-occupancy permit under Chapter 1110 before letting anyone move in. The section carves out one hard limit on the Director's power: a license cannot be suspended or revoked over activity connected to domestic violence, including a tenant's own 911 calls.

Owners get a real appeal path. Section 825.400.5 lets an owner appeal a suspension or revocation in writing to the Director within 10 working days of notification, triggering a contested hearing with written findings due within 10 days of the hearing's conclusion. Once a suspension or revocation is effective, the owner cannot sign a new lease for the affected property, and a misrepresentation-based suspension bars new leases anywhere in the owner's portfolio until the license is reinstated.
