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. It's actually pretty common for landlords to have rules against subleasing.They usually prefer to have direct control over who lives in their property. Tenants generally can't sublet their unit without the landlord's consent. Protect your rentals with Avail lease agreements and amendments. Subletting without permission isn't only against your lease contract, I'm fairly sure it's illegal. Subletting a property is legal unless prohibited in the lease agreement using a no subletting clause. Refrain from taking on additional occupants or subleasing without the landlord's written permission. There is no law specifically covering a sublet fee.
