Nonetheless, “we continue to recognize that there are significant differences between commercial and residential tenancies and the policy considerations appropriate to each.” *327Wesson v. Leone Enters., Inc., supra at 719. As we have said in other contexts, “the bargaining power of commercial tenants at the lease drafting stage is ordinarily greater than that of residential tenants,” 21 Merchants Row Corp. v. Merchants Row, Inc., 412 Mass. 204, 207 (1992), and “[c]ommercial tenants tend to be more sophisticated about the terms of their leases and, unlike residential tenants, commercial tenants generally purchase liability insurance.” Seaco Ins. Co. v. Barbosa, 435 Mass. 772, 778 (2002). For those reasons, we stated that “logic would dictate that, if we were to differentiate between residential and commercial leases, we would do so in favor of residential rather than commercial tenants,” 21 Merchants Row Corp. v. Merchants Row, Inc., supra (commercial landlord may unreasonably refuse consent to assignment of lease; no greater protection for commercial tenants than for residential tenants), and we declined to extend the rule protecting residential tenants in Peterson v. Silva, 428 Mass. 751 (1999) (absent contrary express provision in lease, residential tenant deemed to be coinsured under landlord’s fire insurance policy), to commercial tenants. Seaco Ins. Co. v. Barbosa, supra at 777-779. We have also recognized that “modem notions of consumer protection” have played a role in the development of the law regarding residential leases, and in particular in the emergence of “the almost universally recognized warranty of habitability implied in residential leases.”6 Wesson v. Leone Enters., Inc., supra at 717, 718. Such notions of consumer protection have no applicability to dealings between businesses. In view of the significant differences between residential and commercial tenancies, we decline to extend Young v. Garwacki, supra.
