In Portugal, a rental contract gets automatically renewed unless one of the parties ends it. Tenants need to give at least two months’ notice before leaving a property. Generally, you are allowed to alter fixtures, but you should check your contract or run it by the owner. If the landlord finds any damage to the property, they can keep your deposit at the end.
Usually, you are not allowed to sublet (subarrendar) your space unless it is in the contract. As such, you should always ask your landlord for permission. Furthermore, according to Decree-Law no. 47344 article 1062 (in Portuguese), you cannot charge the sub-tenant more than 20% of the amount stated in the original contract. If you’re planning on moving out before your lease ends, check your notice clause. Typically, you need to notify your landlord in writing at least two months before leaving. The landlord may arrange an inspection to confirm that everything is in order. If you paid a deposit at the start, they should return the total value to you unless there are damages to the property.
