Burglary at Samantha Ronson's House

Cops were called to Samantha Ronson's house Monday night after someone broke into her garage.

We're told the 911 call came in just before 7 PM.  Law enforcement sources tell TMZ ... the burglars didn't make it inside Sam's house. 

It's unclear what -- if anything -- was taken.

As you probably know, Sam lives right next to Lindsay in Venice, CA.

UPDATE: Law enforcement sources tell us ... one item was taken from Sam's garage, worth about $1,000.
