Before subleasing, tenants in Utah must get explicit written consent from their landlord. Subletting is a real estate arrangement where a tenant leases their rental property or part of it to another individual, known as a subtenant.Tenants generally can't sublet their unit without the landlord's consent. Protect your rentals with Avail lease agreements and amendments. The Bottom Line: Utah laws do not explicitly permit nor prohibit sublets, so you must follow the terms of your lease. 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. Before You Rent helps to understand the process of applying for housing, how to avoid rental fraud, renting a dwelling and understanding situations that arise.
