If you are the plaintiff, unless this is a post foreclosure eviction, you should be using the Judicial Council form complaint for unlawful detainer.
The elements of unlawful detainer when a defendant has defaulted in the payment of rent are: 1) that the defendant was served with a three-day written notice to pay rent or quit, 2) the amount of rent due, 3) the non-payment within such period, and 4) the continued possession of the premises without permission. (California Code of Civil Procedure §§ 1161(2), 1166. )
In California, the manner of attacking a complaint that fails to state facts sufficient to constitute a cause of action for unlawful detainer is by motion to quash and not by general demurrer. (Delta Imports Inc. v. Municipal Court (1983) 146 Cal. App. 3d 1033, 1035-36.)
Even though California Code of Civil Procedure § 1170 indicates that a defendant in an unlawful detainer action may "answer or demur," the courts have held that the "only" acceptable procedure to test whether a complaint states a cause of action supporting a five day summons is a motion to quash. (Id. at 1036; Greener v. Workers' Compensation Appeals Bd. (1993) 6 Cal.4th 1028, 1036.)
