You can expunge a felony conviction in California provided you did not serve any time in state prison. An expungement, means that your conviction record is not accessible to the public such as employers or landlords. However, it can still be used to enhance your sentence if you commit another felony offense. In most cases, a conviction that was deemed a “strike” will have included state prison time so that it could not be expunged. If not, then it could be expunged if other criteria is met.
