arrest with no warrant

In the State of California is it legal to enter a persons home and arrest them without a warrant present?

Yes, unless the police have the occupant's consent to enter or there are "exigent circumstances," such as a danger the suspect will excape, destroy evidence, etc.

answer?

calatty's answer makes no sense that I can see unlees he meant "No.....", am I missing something?

Police may enter a home to make an arrest without a warrant if they feel the person being arrested could attempt escape or arm themselves and cause injury or death to a police officer. This method is also used if it could give the person a chance to destroy evidence that could be used against them. The police only need a warrant if they intend to search for evidence that that may be hidden or concealed.

Oops, I thought you said "illegal." No, it is not legal to enter without a warrant unless as specified. And no, it is not true that police only need a warrant if they want to search. They need a warrant to enter a home even if all they want to do is arrest.
