FINDINGS AND RECOMMENDATIONS
EDMUND F. BRENNAN, Magistrate Judge.
On April 23, 2013, defendant Joan Ida Howard, proceeding pro se,  filed a notice of removal of this unlawful detainer action from the Superior Court of the State of California for Sacramento County. Dckt. No. 1.
This court has an independent duty to ascertain its jurisdiction and may remand sua sponte for lack of subject matter jurisdiction. See 28 U.S.C. § 1447(c). "The burden of establishing federal jurisdiction is on the party seeking removal, and the removal statute is strictly construed against removal jurisdiction." Emrich v. Touche Ross & Co., 846 F.2d 1190, 1195 (9th Cir. 1988). "Federal jurisdiction must be rejected if there is any doubt as to the right of removal in the first instance." Gaus v. Miles, Inc., 980 F.2d 564, 566 (9th Cir. 1992). As explained below, defendant has failed to meet that burden.
Defendant's notice of removal states that this court has federal question jurisdiction pursuant to 28 U.S.C. §§ 1441 and 1331. Dckt. No. 1 at 2. However, the complaint does not allege any federal claims. Instead, plaintiffs allege only a claim for unlawful detainer under state law. Dckt. No. 1 at 9-10 (Compl.). The existence of a federal question to support removal jurisdiction must be established by the allegations of the complaint. Thus, the presence or absence of federal question jurisdiction "is governed by the well-pleaded complaint rule, ' which provides that federal jurisdiction exists only when a federal question is presented on the face of plaintiff's properly pleaded complaint." Caterpillar, Inc. v. Williams, 482 U.S. 386, 392 (1987). This is the case where the complaint "establishes either that  federal law creates the cause of action or that  the plaintiff's right to relief necessarily depends on resolution of a substantial question of federal law." Williston Basin Interstate Pipeline Co. v. An Exclusive Gas Storage Leasehold & Easement, 524 F.3d 1090, 1100 (9th Cir. 2008) (quoting Franchise Tax Bd. v. Constr. Laborers Vacation Trust, 463 U.S. 1, 27-28 (1983)). Here, plaintiffs' one cause of action is for unlawful detainer under state law, and under the well-pleaded complaint rule, a defendant's claims or defenses may not serve as a basis for removal. See Takeda v. Nw. Nat'l Life Ins. Co., 765 F.2d 815, 822 (9th Cir. 1985).
Defendant argues that plaintiffs failed to comply with the Protecting Tenants at Foreclosure Act ("PTFA"), 12 U.S.C. §§ 5201 et seq. Dckt. No. 1 at 3. However, "defendants assertions of the Protecting Tenants at Foreclosure Act' are best characterized as defenses or potential counterclaims; neither of which are considered in evaluating whether a federal question appears on the face of a plaintiff's complaint." First N. Bank of Dixon v. Hatanaka, 2011 WL 6328713, at *4 (E.D. Cal. Dec. 16, 2011). "[F]ederal district courts have held that a defense based on the Protecting Tenants at Foreclosure Act cannot serve as a basis for removal jurisdiction." Aurora Loan Servs., LLC v. Montoya, 2011 WL 5508926, at *4 (E.D. Cal. Nov. 9, 2011) (citing SD Coastline LP v. Buck, 2010 WL 4809661, at *1-3 (S.D. Cal. Nov. 19, 2010); Wescom Credit Union v. Dudley, 2010 WL 4916578, at *2 (C.D. Cal. Nov. 22, 2010) ("provisions [of the PTFA] offer [defendant] a federal defense to an unlawful detainer action where the plaintiff fails to comply with these requirements. A federal defense, however, does not support federal-question jurisdiction."); Aurora Loan Servs., LLC v. Martinez, 2010 WL 1266887, at *1 (N.D. Cal. Mar. 29, 2010)).
Because defendant has not adequately established a basis for this court's subject matter jurisdiction, the case must be remanded. See 28 U.S.C. § 1447(c).
Accordingly, IT IS HEREBY RECOMMENDED that the above-captioned case be REMANDED to the Superior Court of the State of California in and for the County of Sacramento.
