No, as a general rule, a tenant cannot validly sublet rented property in Ahmedabad without the landlord's explicit permission, and doing so without authorization exposes the tenant to eviction and potential legal consequences, since subletting without consent is treated as a serious breach of the tenancy relationship under both general property law and Gujarat's rent control framework. Under Section 108 of the Transfer of Property Act, 1882, which governs the rights and liabilities of lessors and lessees in the absence of a contract to the contrary, a lessee is entitled to transfer their interest in the property, but this general right is very commonly restricted or entirely prohibited by the specific terms of the lease or rental agreement itself, and most standard rental agreements explicitly bar subletting without the landlord's written consent.

Beyond contractual restrictions, unauthorised subletting is also specifically recognised as valid grounds for eviction under rent control legislation applicable in Gujarat, where such protections apply to the tenancy — landlords can seek eviction specifically on the ground that the tenant has sublet, assigned, or otherwise parted with possession of the property, in whole or in part, without obtaining the landlord's consent as required, which is treated as a fundamental violation of the trust underlying the tenancy relationship.

If a landlord discovers unauthorised subletting, the appropriate remedy is to issue a legal notice to the original tenant terminating the tenancy on the specific ground of unauthorised subletting, followed, if the tenant and sub-tenant fail to vacate, by a suit for eviction and recovery of possession before the appropriate civil court, joining both the original tenant and any sub-tenant as parties to ensure the eventual decree can be enforced against whoever is actually occupying the property. Since the sub-tenant's rights are entirely derivative of, and dependent on, the original tenant's rights, if the original tenancy is validly terminated for unauthorised subletting, the sub-tenant generally acquires no independent right to continue occupying the property against the landlord's wishes, regardless of what arrangement existed between the tenant and sub-tenant.

Where the original rental agreement did permit subletting under certain specified conditions (such as with prior written landlord consent, or restricted to certain circumstances), the tenant's compliance with those specific conditions becomes the central factual question in any resulting dispute, making the precise wording of the original agreement particularly important evidence.

Given how much these disputes depend on the exact terms of the original tenancy agreement and applicable rent control provisions, careful review before initiating eviction proceedings is genuinely valuable.
