   OPINION OF THE COURT

SCIRICA, Circuit Judge.

Harry Lipsehultz and the estate of his mother Sylvia Lipsehultz, property owners in the Logan section of Philadelphia, filed this § 1983 claim based on the City of Philadelphia’s decision to compensate only residential landowners for property damage in the neighborhood. Because the Lipschultzes’s causes of action were time barred, we will affirm.

I.

The City first discovered that Logan buildings were sinking in 1984. In September 1986, Philadelphia Mayor Wilson Goode issued a compensation letter to Logan residents affected by the property damage. The policy authorized the City to provide compensation for residents who wished to move out of Logan but excluded businesses and mixed-use properties from compensation packages.

The Lipschultzes owned four properties in the Logan section of Philadelphia, consisting of residential units and a family pharmacy. The City offered to compensate the Lipschultzes for their residential units, but they decided to remain in Logan. A decade later, in July 1997, the family sold the pharmacy’s assets. In May 1999, the Lipschultzes initiated these lawsuits against the City and its representatives. The District Court granted summary judgment in favor of the City and the other defendants on some counts and dismissed the other counts without prejudice. We consolidated the separate cases on this appeal.

II.

The District Court had jurisdiction under 28 U.S.C. § 1331 and 28 U.S.C. § 1367. We have jurisdiction under 28 U.S.C. § 1291.

III.

A federal court should apply the state’s statute of limitations for personal injury claims brought under 42 U.S.C. § 1983. E.g., Sameric Corp. v. City of Philadelphia, 142 F.3d 582, 599 (3d Cir. 1998). In Pennsylvania, the relevant statutory period is two years. See Pa. Cons. Stat. Ann. § 5524 (West Supp.1997). This period begins to toll from the time a grievant “knew or should have known of the injury upon which its action is based.” Sameric, 142 F.3d at 599.

Here, the Lipschultzes knew of their injuries as far ■ back as 1986. Mayor Goode’s initial correspondence to Logan community members specifically offered compensation only to owner-occupants of residential units. This letter put the Lipschultzes on notice of their pharmacy’s ineligibility for compensation.

The Lipschultzes admit they “were aware of the City’s policy of not compensating businesses.” Brief for Appellants at 48. Nevertheless, they argue they did not incur an actionable injury until they “gave up on Logan and sold their assets.” Id. Based on Mayor Goode’s letter, the Lipschultzes knew or should have known residents would depart Logan and injure their pharmacy’s business. At the very least, they admitted in a March 15, 1996, letter that their neighborhood had been “decimated” by the departure of many residents. Nevertheless, they did not file claims until May 25,1999.

As the Supreme Court has recognized, statutes of limitations are not “simply technicalities,” but rather, “fundamental to a well-ordered judicial system.” Board of Regents v. Tomanio, 446 U.S. 478, 487, 100 S.Ct. 1790, 64 L.Ed.2d 440 (1980). Here, the statute of limitations bars the Lipschultzes’ claims.

IV.

In an effort to revive their time-barred claims, the Lipschultzes argue the City’s disbursement of federal and local funds to Logan residents constituted continuing violations. The continuing violations doctrine is an “equitable exception to the timely filing requirement.” West v. Philadelphia Elec. Co., 45 F.3d 744, 754 (3d Cir.1995).

To determine whether there was a continuing violation, we undertake a three-factor analysis of the defendant’s affirmative acts. Cowell v. Palmer Twp., 263 F.3d 286, 292-93 (3d Cir.2001) (“The focus of the continuing violations doctrine is on affirmative acts of the defendants.”). Specifically, we look to the subject matter, frequency, and degree of permanence of the defendant’s conduct. Id. (holding that the degree of permanence is the “most important of the factors”); see also Berry v. Board of Supervisors, 715 F.2d 971, 981 (5th Cir.1983). To establish a continuing violation, the plaintiff has the burden of proving that the defendant’s conduct is “more than the occurrence of isolated or sporadic acts.” Cowell, 263 F.3d at 292 (quoting West, 45 F.3d at 755).

The Lipschultzes did not meet their burden here. “A continuing violation is occasioned by continual unlawful acts, not continual ill effects from an original violation.” Id. at 293 (quoting Ocean Acres Ltd. v. Dare County Bd. of Health, 707 F.2d 103, 106 (4th Cir.1983)). In Cowell, a township, imposed two municipal liens on plaintiffs’ land. Plaintiffs failed to bring their § 1983 claim until six years after the imposition of the second lien, long after the statute of limitations had run. We held the Township’s conduct in issuing the liens and later refusing to remove them constituted a single, rather than continual, act, meaning the continuing violations doctrine did not apply.

Here, the Lipschultzes’ argument rests on the premise that each disbursement to Logan residents represented a separate unlawful act. But these disbursements were merely consequences of the City’s policy rather than independent discriminatory conduct. As the Supreme Court expressed, “the proper focus [for the continuing violation theory] is upon the time of the discriminato'ry acts, not upon the time at which the consequences of the acts become most painful.” Delaware State College v. Ricks, 449 U.S. 250, 258, 101 S.Ct. 498, 66 L.Ed.2d 431 (1980) (emphasis in original). Here, the allegedly discriminatory act occurred in September 1986 when the City issued its policy excluding businesses and mixed-use properties from compensatory relief. All of the Lipschultzes’ injuries stem from this single, permanent act, meaning the continuing violations doctrine does not apply.

V.

For the foregoing reasons we will affirm the judgment of the District Court. 
      
      . This doctrine also is known as the "continuing wrong” doctrine. E.g., Sameric Corp. v. City of Philadelphia, 142 F.3d 582, 599 (3d Cir.1998).
     
      
      . The decision cited by the Lipschultzes, Brenner v. Local 514, 927 F.2d 1283, 1296 (3d Cir.1991), does not support their proposition. Brenner involved repeated hostile acts by the Local against certain union members. This pattern of continual conduct was not present in Cowell nor this case.
