From The Civil Rights Lawyer:

The too-long-didn’t-watch answer is no. If police officers are on your private property, that changes things. Cops are trained on the requirement for reasonable suspicion – to develop some reasonable suspicion they can articulate, even if total B.S., and then that entitles them to forcibly demand identification from whomever they deem a suspect. That is generally how things work in public places – but not on private property, especially a home. 

According to the 1980 Supreme Court opinion in Payton v. New York, in order to legally arrest someone in a home, rather than in a public place, absent consent or exigent circumstances, police officers must have a warrant.
