LAUREL BEELER, Magistrate Judge.
This is a case under the Americans with Disabilities Act ("ADA") and similar California statutes. Plaintiff Jose Daniel Castillo-Antonio alleges that a store in Richmond is inaccessible to wheelchair occupants and violates other requirements of federal and state law. (1st Am. Compl. — ECF No. 13 at 2-4.)
Pleading amendment is governed primarily by Rule 15 of the Federal Rules of Civil Procedure. Rule 15(a)(2) provides that a "court should freely give leave [to amend] when justice so requires." Fed. R. Civ. P. 15(a)(2). "[T]his policy is to be applied with extreme liberality." Sonoma County Ass'n of Retired Employees v. Sonoma County, 708 F.3d 1109, 1117 (9th Cir. 2013). Rule 15 must be read in conjunction with Rule 21, which states: "On motion or on its own, the court may at any time, on just terms, add or drop a party." Fed. R. Civ. P. 21. The Ninth Circuit has said: "Courts may decline to grant leave to amend only if there is strong evidence of `undue delay, bad faith or dilatory motive on the part of the movant, repeated failure to cure deficiencies by amendments previously allowed, undue prejudice to the opposing party by virtue of allowance of the amendment, [or] futility of amendment, etc.'" Sonoma County, 708 F.3d at 1117 (quoting Foman v. Davis, 371 U.S. 178, 182 (1962)).
The court finds that none of these factors (of the ones potentially relevant here) impedes the sought amendment. Above all, allowing Mr. Castillo-Antonio to add Emam as an owner of the subject property would not unduly prejudice any of the other parties. The plaintiff's lawyer explains that he learned of the quitclaim deed sometime after he filed the First Amended Complaint. (ECF No. 18-1 at 1, ¶ 1.) This was on December 16, 2014. (ECF No. 13.) The plaintiff filed this motion to amend on March 9, 2015. (ECF No. 18.) In the context of this case, this does not amount to undue delay. This is especially true given that this case is in its earliest stages. See Sonoma County, 708 F.3d at 1118 ("[T]he mere fact that an amendment is offered late in the case .. . is not enough to bar it.") (quoting authorities). Delay moreover must be accompanied by the movant's bad faith, futility in making the amendment, or prejudice to non-moving parties. Bowles, 198 F.3d at 758. "The consideration of prejudice" to non-moving parties "carries the greatest weight." Sonoma County, 708 F.3d at 1117 (quoting Eminence Capital, LLC v. Aspeon, Inc., 316 F.3d 1048, 1052 (9th Cir. 2003)). Here, the court can see no prejudice from the proposed amendment. Considering all this in light of Rule 15's extremely liberal amendment policy, the court grants the plaintiff's motion for leave to amend.
The plaintiff also asks that he not be required to serve the Second Amended Complaint on the defaulted defendants, Barron and Harbi. (ECF No. 18 at 4-5, ¶ 7.) He notes that Barron has defaulted twice and Harbi had defaulted once. (See ECF Nos. 9, 17.) He observes that the new complaint "changes nothing about the allegations [in this case]. It merely adds the new defendant, Bahman Emam." (ECF No. 18 at 4-5, ¶ 7.) The court acknowledges the plaintiff's discomfort at being put to the expense of again serving defendants who have already defaulted. The court must also be mindful, however, of the strong federal policy in favor determining cases, whenever possible, on the merits. See, e.g., Eitel v. McCool, 782 F.2d 1470, 1471-72 (9th Cir. 1986). In view of that policy, and the facts of this case, the court orders the plaintiff to serve the Second Amended Complaint on defendant Harbi. The plaintiff need not serve Barron. Should the plaintiff move for default judgment, the court will direct the plaintiff to serve copies of its motion on all defendants (though, at that point, notice short of formal service may suffice).
The court grants the plaintiff's motion (ECF No. 18) to amend his complaint to add Bahman Emam as a defendant. The court orders the plaintiff to serve, not only the new defendant, Bahman Emam, but also the defaulted defendant, Ali Harbi. The plaintiff need not serve the defaulted defendant, Cuauhtemoc Barron. The court directs the clerk to file the Second Amended Complaint that is attached (ECF No. 18-3) to the plaintiff's motion.
This disposes of ECF No. 18.
