If you have a lease for a set term, like one year, you can sublet with or without your landlord's permission, unless they prohibit this in the written lease. I have a friend which is "subletting" an apartment (as the sublet tenant, Person B). Apparently the tenant (Person A) cannot sublet per its contract.Subletting is the same as subleasing; the two words are interchangeable. As long as your landlord, or state law, approves, anyone can sublet. Our condo association rules say anyone living in the condo must submit an application and authorize a background check. Tenants generally can't sublet their unit without the landlord's consent. Protect your rentals with Avail lease agreements and amendments.
