No duty shall devolve upon the landlord to repair a defective condition under this section, nor shall any defense or remedy be available to the tenant under this chapter, where the defective condition complained of was caused by the conduct of such tenant, his or her family, invitee, or other person acting under his or her control, or where a tenant unreasonably fails to allow the landlord access to the property for purposes of repair. When the duty imposed by subsection (1) of this section is incompatible with and greater than the duty imposed by any other provisions of this section, the landlord's duty shall be determined pursuant to subsection (1) of this section.
