Happy Birthday Justin Bieber

Justin Bieber is going to get an awesome birthday present from his mom -- a fancy schmancy L.A. home ... TMZ has learned.

Sources connected with Justin tell TMZ ... Justin's mom and grandmother have been looking for a condo or home in the L.A. area, which they want to close before Justin's 17th birthday on March 1.

We're told the top contender so far -- a $1.7 million condo near the Westwood area of L.A.

Justin's grandma thinks the condo is perfect, but they're still looking.

The condo is 2,400 square feet with 3 bedrooms and 4 bathrooms.

The owner is a model.  Watch out ... Justin's a lady killer!

The impending purchase was first reported by the Real EStalker.
