Chris Brown -- Good Riddance Hollywood Hills -- I'm Going to Malibu!

Chris Brown has had enough of grumpy neighbors who don't appreciate him or his spray-painted exterior ... so he's selling his $1.5 million Hollywood Hills home and heading for the beach .... TMZ has learned.

Real estate sources tell us .... Chris wrote an offer on a house in Malibu in an exclusive, gated community where a bunch of other high profile celebrities live.

Our sources say ... the last straw for Chris was when he got cited by the City of L.A. for tagging his crib.

So here's the irony. If Chris thinks he's having problems with the neighbors in the Hollywood Hills, wait till he sees what happens in Malibu, where houses are worth between $3 million and $30 million. The city of Malibu comes down hard on anyone who violates the building codes -- which cover graffiti.

And the Malibu neighbors don't like people racing their cars up and down the streets in the middle of the night. And they don't like all-night ragers either.

As for Chris' Hollywood Hills neighbors ... when they heard the news they decided to throw their own celebratory rager.
