There is free parking in the neighborhood on Hayworth up until 700 PM. Please avoid if you are going to remain after 7 because it is a permit parking zone at that point and the WeHo parking enforcement is notorious for ticketing vehicles. You can also park a block or two down Hayworth on Romaine St. or Willoughby Ave. anytime of day.
There are meters on Santa Monica Blvd and Fairfax. These meters have 2 hour limits.
There is an inexpensive parking garage across the street from Whole Foods Market on the west side of Fairfax, just north of Santa Monica. It is the first driveway. It would cost you $2.00 to park for the hour or you can validate the pass at Starbucks.
