Grant Deed with County (CA) Trigger Property Reassessment?

[Simon Gill]

I'm adding my brother to the property deed through a grant deed.  I purchased this property back in 2011.  My name will still remain on the property deed now will this recorded deed with the County trigger a property tax re-assessment?  The value of this property has doubled and would hate to see the property tax doubled.  The property is in Ventura County, California. Please advise.
