Does my friend need to inform immigration if staying in my rented house in Thailand?

When a foreigner stays in a rented property in Thailand, the property owner or tenant is technically required to report the visitor to immigration via the TM30 form. However, if the friend is not using any immigration services during their stay, the necessity to report may not be critical. Some users suggest that for short visits, it is usually not a problem if notification is not made, while those staying for a longer duration are advised to report it. Additionally, registration can often be completed online for convenience.
