Missouri Landlord Entry and Tenant Privacy

No Missouri statute requires a landlord to give notice before entering a rented dwelling or limits the time, place, or manner of entry. Chapter 441 contains no right-of-entry provision, so entry terms are set by the lease. In practice most landlords give 24 hours' notice as a courtesy, but this is not legally mandated. Because there is no statutory standard, a tenant's protection comes from the lease and general law: a landlord who enters in violation of the lease, or whose conduct amounts to harassment or interference with quiet enjoyment, may face a claim for breach of the rental agreement and damages or injunctive relief. Emergency and code-compliance entries are generally recognized regardless of notice.

No specific statutory penalty. A tenant may pursue contract remedies (damages, injunction) for breach of the lease or interference with quiet enjoyment; egregious repeated entry could implicate criminal harassment under separate law.
