What are the key differences between a commercial sublease and a lease assignment?

A sublease maintains the relationship between the original tenant and landlord while creating a new agreement between the original tenant and subtenant, whereas an assignment transfers all lease obligations directly to the new tenant, completely releasing the original tenant from liability.

How does liability work in a commercial sublease agreement?

The original tenant typically remains primarily liable to the landlord under the original lease terms, while the subtenant becomes directly liable to the original tenant for obligations under the sublease, creating a layered responsibility structure.

Can a subtenant further sublease the space to another party?

Subleasing authority must be explicitly permitted in both the original lease and the sublease agreement, as most commercial leases contain restrictions against further subletting without landlord consent.

What happens if the original lease is terminated before the sublease ends?

If the original lease terminates, the sublease agreement typically also terminates, leaving the subtenant vulnerable to eviction unless separate arrangements are made directly with the original landlord.

How are utility payments typically handled in commercial subleases?

Commercial subleases often require the subtenant to pay utilities directly to service providers, while larger buildings may include utilities in a separate charge calculated based on actual usage or square footage allocation.

Risks & common mistakes to avoid

⚠
Insufficient Due Diligence
Failing to thoroughly review the original lease terms can lead to unexpected restrictions, termination clauses, or obligations that severely impact sublease viability and potentially create legal liability for the subtenant.
⚠
Unclear Subordination Clauses
Ambiguous language regarding subordination and attornment can create conflicts between the original tenant, subtenant, and landlord regarding priority of claims and lease enforceability in default situations.
⚠
Landlord Consent Requirements
Commercial subleases typically require original landlord consent, and proceeding without proper documentation can result in termination of both the original lease and sublease, creating immediate eviction risks for the subtenant.
⚠
Rent Increase Provisions
Inadequate provisions for handling potential rent increases outlined in the original lease can create unexpected financial burdens on the subtenant or trigger termination clauses that disrupt business operations.
