When rent has been properly paid, Kansas landlords must always provide 30 days of advance notice when they intend for a tenant to move out. However, in a more punitive situation (such as in the wake of a lease violation or missed rent payment), a landlord may only provide as many as 10 days or as few as 3 days for their tenant to remedy the issue or move out.
