The Bottom Line: Utah laws do not explicitly permit nor prohibit sublets, so you must follow the terms of your lease. If your lease prohibits sublets, then sadly, you aren't allowed to sublet. You should always obtain written approval from your landlord prior to subletting. Check your lease.
Consent from the landlord A tenant must get a landlord's written permission to sub-let or transfer any part of the property. If a tenant does this without consent, they are breaching the terms of the tenancy agreement.
These laws are designed to deter fraudulent activity and protect landlords from illegal profits made by tenants who sublet their properties without permission. Unauthorized subletting is considered a criminal offense, punishable by law, as it involves a breach of trust and a violation of the landlord-tenant agreement.
If your tenancy doesn't have a fixed end date you'll need your landlord's permission to sublet your whole home. If they say no, they don't have to give you a reason. If there's a fixed end date for your tenancy, you're allowed to sublet your whole home.
If your tenant did not get your permission to sublet and you have a sublet clause in your lease, they have officially broken the lease. This means you can send out a notice to comply or vacate the property. Subletting without permission is cause for eviction, but you aren't required to evict the tenant.
In short, subletting means renting out a room or apartment to someone that you are already renting. So, for example, let's say you live in an apartment, and your name is on the lease. The apartment is a 2/2, and you live there with a friend. After 12-months, your friend moves, but you want to keep the apartment.
In an ideal situation, tenants would notify you of their plans to sublease a rental property. But in the case of an illegal sublease, you may find a new tenant living in your rental property without your consent.
New York City law allows market-rate and rent-stabilized tenants to sublet their apartments if they live in a building with four or more units. New York City law does not allow tenants that live in multiple dwellings (3 apartments or more) to sublet apartments for less than thirty days.
Without the landlord's consent, any sublease might be unenforceable, potentially leading to legal disputes or eviction. Obtaining written permission helps protect all parties involved and ensures the sublease adheres to local laws and regulations.
