Can Landlords Screen New Roommates Before Approval in Missouri?

When renting a property in Missouri, tenants often want to bring in new roommates to share the living space and expenses. This situation raises important questions about the landlord’s rights regarding screening and approving new roommates. Understanding Missouri’s laws on this topic helps both tenants and landlords navigate roommate changes smoothly and legally.

Landlord’s Right to Screen New Roommates

In Missouri, landlords do have the right to screen prospective roommates before approving them to live in the rental unit. This right stems from the landlord’s interest in maintaining control over who occupies their property and ensuring all residents meet reasonable rental criteria.

Key points regarding landlord screening in Missouri:

  • Lease Terms and Addendums:
Most rental agreements or leases include specific provisions about adding roommates. These provisions typically require tenants to seek the landlord’s approval before allowing a new person to move in. The landlord can make approval contingent upon screening the prospective roommate.
  • Screening Process:
Landlords can conduct background checks, credit checks, and verify employment or rental history for new roommates, similar to the process they used for the original tenant. This helps landlords assess risk and suitability.
  • Permission Required:
Tenants must obtain written permission from the landlord before adding a roommate. If a tenant fails to do so, the landlord might have grounds for lease violation notices or eviction proceedings.
  • Reasonable Grounds for Denial:
Missouri law does not mandate landlords to approve every roommate request. Landlords can deny a new roommate based on lawful, non-discriminatory reasons such as poor credit history, criminal record, or inability to pay rent.

Tenant’s Rights Regarding Guests Versus Roommates

It is important to distinguish between guests and roommates in Missouri rental law:

  • Guests:
Tenants are generally permitted to have guests for short periods without landlord approval. Missouri law does not specify a precise duration, but long-term or permanent residency by a guest without landlord consent can be treated as a violation of the lease.
  • Roommates:
A new roommate is someone who will reside in the unit on a more permanent basis, sharing the rent and obligations. Introducing a new roommate typically requires landlord consent.

Best Practices for Tenants Adding a Roommate in Missouri

To ensure compliance and prevent disputes, Missouri tenants should follow these steps when adding a roommate:

  1. Review the Lease Agreement:
Carefully read the lease to understand the tenant’s obligations regarding adding roommates.
  1. Notify the Landlord Early:
Inform the landlord in writing about the intent to add a roommate and request the procedure for approval.
  1. Provide Necessary Information:
Be prepared to have the new roommate complete an application form and consent to background or credit checks.
  1. Obtain Written Approval:
Do not allow the new roommate to move in without a formal, written approval from the landlord.
  1. Clarify Lease Adjustments:
Confirm whether the roommate will be added to the lease or subject to a lease addendum outlining responsibilities such as rent payment and damages.

Landlord Considerations for Screening Roommates

Missouri landlords should also be mindful of fair housing laws and proper screening procedures when evaluating new roommates:

  • Fair Housing Compliance:
Landlords cannot discriminate against prospective roommates based on race, color, national origin, religion, sex, familial status, or disability.
  • Consistent Application of Criteria:
Screening criteria and approval processes should be applied uniformly to all applicants to avoid claims of discrimination.
  • Written Policies:
Having clear, written policies in the lease or rental agreement about roommate approval and screening helps prevent misunderstandings.

Summary

In Missouri, landlords have the right to screen new roommates before granting approval, and tenants are required to seek such approval when adding a new occupant. This process typically involves background and credit checks similar to those for original tenants. Tenants should carefully follow lease terms and communicate openly with landlords to ensure a smooth roommate addition. Both parties benefit from clear procedures and written agreements outlining the responsibilities related to new roommates.
