Can you rent out storage space and housing on same property?

[Brad Beadling]

Hello all!

I am curious if there is anything illegal about renting a home to tenants and in addition renting out storage space to someone who is not renting the property.  

For example if I bought a multi-family property with a garage AND a pole barn, could I rent out the house (along with the garage) to a tenant, but also rent out the pole barn separately for storage to make extra cash flow on the property? 

Similarly could I purchase a property and rent out the home to tenants, and in addition build a pole barn on the property to rent out separately?

Thanks in advance!
