It depends on which near wall approach you're using: wall functions or resolving the viscous sub layer.  Read the User's and Theory Guides for wall treatment.

Ok Thank You for the reply....Earlier Rahul Raghav has forwarded one article on this which was very understanding is that, if you want to resolve the viscous sub-layer,irrespective of which turbulence model you use(k-w SST,K-Epsilon or RSM) your Y+ should be below 5 or close to 1.Pls comment on that.

Correct, but you also need to include suitable wall functions for RSM as the default is designed for  30 < y+ < 300  hence me advising you read up on the wall treatment.
