Most leases (rental property) state the number of persons residing in the home and may limit the stay of guests (generally no more than 2 weeks in a 30 day period). My understanding of a mobile home is that you own the mobile home and rent the lot. If the lot owner has no restrictions stated in your agreement, then I am under the guidance that you have no guest restrictions. In that instance, I am not aware of any limitation on the length of your guest's stay at your home. If you are leasing the mobile home, then carefully review the lease.
