"The implied warranty of habitability ‘is concerned with the provision, maintenance, and repair of the physical facilities vital to the use of the leased premises.’ Not every breach of the State sanitary code supports a claim under the implied warranty of habitability.” McAllister v. Boston Housing Authority, 429 Mass. 300, 305 (1999) (quotations omitted). However, as to those requirements that make up fitness for habitation, the doctrine of warranty affords a tenant compensation not only for economic loss, as in Berman and Hemingway, but for personal injury. Young v. Garwacki, supra, 380 Mass. at 168, citing Crowell v. McCaffrey, 377 Mass. 443 (1979). See also Doe v. New Bedford Housing Authority, 417 Mass. 273, 282 n.10 (2000). And, in such a case, the landlord is strictly liable. “Considerations of fault do not belong in an analysis of warranty.” Berman & Sons, Inc. v. Jefferson, 379 Mass. 196, 200 (1979). Thus, when a tenant suffers personal injury as a result of a landlord’s breach of the implied warranty of habitability, the landlord’s contractual obligation to the tenant requires the payment of compensatory damages, to the tenant under a strict liability standard. It makes no sense to suggest that if the same violation of the implied warranty of habitability takes place and causes injury to a guest who happens to be seated next to the tenant or who is standing behind the tenant, that the landlord should be liable, if at all, under a negligence standard. Compare J.C. Melick, “The Standard of Care In Warranty of Habitability Cases,” 82 Mass. L.Rev. 187, 194 (1997) (noting the anomaly [“Creating a strict liability standard for tenants in warranty of habitability cases, while maintaining a reasonable care standard for guests and other lawful visitors, would create a return to the archaic system of devising different classes of plaintiffs”) but suggesting, instead, that the solution is to eliminate strict liability entirely, and to limit both tenants and guests to a remedy for negligence).
