f 1 — The chief question here is whether the Washington statute providing for judicial enforcement of statutory condominium warranties must yield to the federal arbitration statute solely because some construction materials came from outside Washington State. We hold that under the circumstances here, the commerce clause does not reach so far and the state statute controls.
Ellington, J.BACKGROUND
¶2 Satomi, LLC (Company) developed the Satomi Condominium, an 85-unit complex located in Bellevue. In 2005, the Satomi Owners Association (Association) filed suit against the Company, alleging numerous construction defects and other deficiencies throughout the complex, and claiming breach of contractual warranties, breach of implied and express warranties under the Washington Condominium Act (WCA), chapter 64.34 RCW, breach of the implied warranty of habitability, and violations of the Consumer Protection Act (CPA), chapter 19.86 RCW.
¶3 The Company denied the allegations and demanded arbitration based on the arbitration clause in the warranty addendum, which was an attachment to the original purchase and sale agreements. The Company asserted that most of the building materials used to construct the condominium were manufactured and shipped in interstate commerce, and the Association’s claims were therefore subject *179to arbitration under the Federal Arbitration Act (FAA), 9 U.S.C. §§ 1-16.
¶4 The Association moved to quash the demand for arbitration, contending it is not bound by the agreement and that in any event, the agreement violates the judicial enforcement provision of the WCA, which is not preempted by the FAA because the contract does not involve interstate commerce.
¶5 The trial court quashed the demand for arbitration motion on three grounds:
(1) The Company did not prove that all of the individual owners agreed to arbitrate.
(2) Even if the individual owners agreed to arbitrate, the Association “is a legally separate corporate entity which is neither a ‘successor or transferee’ to [the Association], Thus, the arbitration clause is simply inapplicable.”1
(3) The FAA does not apply because Marina Cove Condominium Owners Ass’n v. Isabella Estates2 held that condominium sales primarily impact Washington residents.
¶6 The Company appeals. Our review is de novo.3
DISCUSSION
¶7 The Company argues the court erred and that all unit owners agreed to arbitrate their claims, the Association is bound to arbitrate these issues in the same manner as the unit owners, and the FAA applies and mandates arbitration. We agree with the first two arguments, but not the third.
I. Applicability of Arbitration Agreement to Association
¶8 The Association acknowledges that all original owners signed the warranty addendum but contends that later purchasers are not bound by it. This argument has no *180merit. The purchase and sale agreement expressly required original unit owners to bind later purchasers to the terms of the addendum. All owners are therefore bound by the agreement to arbitrate.
¶9 The Association next contends the agreement has no application here because the Association is a separate legal entity.
¶10 The WCA requires condominiums to have a homeowners’ association whose membership consists solely of the unit owners, all of whom must belong.4 Among other powers, a homeowners’ association may “[institute, defend, or intervene in litigation or administrative proceedings in its own name on behalf of itself or two or more unit owners on matters affecting the condominium.”5 An association may act on its own behalf when the proceedings occur “in connection with its own functions and activities.”6 But if an association merely represents its owner/members, its standing is derivative, and it is subject to any defenses and limitations that may be asserted against them and is without a separate right to recover.7 In other words, “ ‘[i]ts claim ... is only as good as that of its constituent members.’ ”8
¶11 Such is the case here. The claims asserted belong to the individual unit owners. In addition to violations of the CPA, the Association alleges breaches of warranties under the WCA, the purchase contract, and the implied warranty *181of habitability, resulting in damage to property owned by its members.9 But the WCA’s express and implied warranties run to the unit purchasers, not the Association;10 the implied warranty of habitability runs from the builder-vendor to the original purchaser;* 11 the contract warranties do not run to the Association; and private rights of action under the CPA belong only to the individual allegedly deceived in a consumer transaction.12 Given the nature of the claims here, the Association necessarily brought this action in a representative capacity, not on its own behalf as a separate juristic entity.
¶12 The Association stands in the shoes of the individual unit owners. The trial court erred when it concluded the arbitration clause does not apply to the Association. If the claims are subject to arbitration, the Association must arbitrate.
¶13 The remaining question is whether statutory warranty claims are subject to arbitration because the FAA preempts state law.
II. Applicability of the Federal Arbitration Act
¶14 The Association contends that we decided this issue in Marina Cove, wherein we held that condominium purchase and sale agreements between Washington companies and Washington residents do not implicate the FAA.13 But as explained below, we must revisit this issue here.
*182 ¶15 Washington has a strong policy favoring arbitration of disputes,14 and any doubts about the scope of arbitrable issues are resolved in favor of arbitration “ ‘whether the problem at hand is the construction of the contract language itself or an allegation of waiver, delay, or a like defense to arbitrability.’ ”15
¶16 Congress also favors arbitration of disputes and to that end enacted the FAA. The FAA’s basic purpose is to overcome courts’ unwillingness to enforce arbitration agreements.16 Where it applies, the FAA preempts state law, prohibiting application of state statutes that invalidate arbitration agreements.17 The FAA provides as follows:
A written provision in any maritime transaction or a contract evidencing a transaction involving commerce to settle by arbitration a controversy thereafter arising out of such contract or transaction, or the refusal to perform the whole or any part thereof, or an agreement in writing to submit to arbitration an existing controversy arising out of such a contract, transaction, or refusal, shall be valid, irrevocable, and enforceable, save upon such grounds as exist at law or in equity for the revocation of any contract.[18]
¶17 The United States Supreme Court most recently considered the scope of the FAA in Citizens Bank v. Alafabco, Inc.,19 which involved debt restructuring arrangements between an Alabama bank and an Alabama construction company. In concluding the transactions were governed by the FAA, the Court described the phrase “involving commerce” as the “functional equivalent of the *183more familiar term ‘affecting commerce’ — words of art that ordinarily signal the broadest permissible exercise of Congress’ Commerce Clause power.”20
¶18 The Court emphasized that the commerce clause power “ ‘may be exercised in individual cases without showing any specific effect upon interstate commerce’ if in the aggregate the economic activity in question would represent ‘a general practice . . . subject to federal control.’ ”21 Only the general practice subject to federal control need have a substantial effect on interstate commerce.22
¶19 The Citizens Bank debt restructuring agreements, although executed in Alabama by Alabama residents, easily met the “involving commerce” test for at least three reasons: (1) Alafabco used funds from loans that were the subject of the debt restructuring agreements to finance large projects throughout the southeastern United States; (2) the restructured debt was secured in part by Alafabco’s inventory of goods assembled from out-of-state parts and raw materials; and (3) the general practice represented by the transactions at issue, commercial lending, has a broad impact on the national economy and is clearly within Congress’ regulatory power.23
¶20 Citizens Bank confirmed the broad reach of the FAA announced in 1995 in Allied-Bruce Terminix Cos. v. Dobson ,24 Allied-Bruce involved a homeowner’s lawsuit against the companies with whom he contracted for termite protection. An Alabama statute disallowed predispute arbitration agreements. Allied-Bruce and Terminix operated in multiple states, and “the termite-treating and house-repairing material used by Allied-Bruce in its (allegedly inad*184equate) efforts to carry out the terms of the [contract], came from outside Alabama.”25 The United States Supreme Court held that the transaction evidenced by the contract need only “in fact” involve interstate commerce,26 which the parties did not dispute. Thus, the FAA applied and preempted the state statute.27
¶21 In another 1995 decision, United States v. Lopez,28 the Court described the test of Congress’ power to regulate as whether the activity sought to be regulated “substantially affects” interstate commerce. This language in Lopez resulted in a number of decisions, including ours in Marina Cove, which came between Lopez and Allied-Bruce in 1995, and Citizens Bank in 2003.
¶22 In Marina Cove, we adopted an interpretation of Lopez enunciated in L&L Kempwood Associates, LP v. Omega Builders, Inc.,29 in which the Texas Court of Appeals held that a contract for repairs to a Texas apartment complex, entered into by an out-of-state property owner and a Texas contractor, was “not a transaction substantially affecting interstate commerce.”30 We applied the same rationale in Marina Cove to hold the FAA did not preempt the WCA:
Similarly here, Marina Cove Condominiums were constructed, marketed, and sold solely within the state of Washington. The contract at issue is a limited warranty offered by a Washington corporation on condominium units located within the state, whose owners all reside in Washington. The only connection to other states involves one buyer, who moved to Washington from another state, and another buyer, who trans*185ferred funds from an out-of-state bank account for use as a down payment on one emit purchased. That negligible contact with other states does not constitute a substantial effect on interstate commerce. The FAA does not apply.[31]
¶23 But in Citizens Bank, the Court rejected the “substantially affecting” interpretation as an “improperly cramped view” of the commerce clause power32 and held that a significant effect on interstate commerce must be shown only as to the general practice subject to federal control.33 Given our application of the discredited “substantially affecting interstate commerce” test, Marina Cove’s continuing validity is questionable.
¶24 We know of only one other case similar to this one: Basura v. U.S. Home Corp.34 A California statute permits court actions in construction defect cases, even where the parties have agreed to arbitrate. The California Court of Appeals held the FAA preempted the statute and required arbitration, on grounds that where a subdivision developer utilized out-of-state architects and contractors, engaged in nationwide marketing and advertising using interstate media, and used building materials and equipment manufactured and shipped from multiple states, the purchase agreement involved interstate commerce.35
¶25 With these authorities in mind, we turn to the claims and facts of this case. The Association’s complaint alleges a “variety of construction defects and other deficiencies in building components and/or installation”36 constituting breaches of common law, statutory, and contractual warranties. The common law warranty is the implied *186warranty of habitability.37 The statutory warranties are set forth in RCW 64.34.443,38 which requires condominium declarants to provide specific implied warranties, and RCW 64.34.445,39 which permits declarants to make express warranties. The warranty addendum to the purchase and sale agreement40 set forth express warranties, which appear identical to those implied by the statute:
*1871. Limited Warranty. The Unit in the Condominium identified above and the Common Elements are suitable for the ordinary uses of real estate of their type and, except as provided below, all parts of the Unit and Common Elements constructed by or for the Declarant are free from defective materials and have been constructed in accordance with applicable law, in accordance with sound engineering and construction standards, and in a workmanlike manner.[41]
¶26 The warranty addendum purports to require arbitration of all warranty disputes:
7. Seller’s Right to Arbitration. At the option of the Seller, Seller may require that any claim asserted by Purchaser or by the Association under this Warranty or any other claimed warranty relating to the Unit or Common Elements must be decided by arbitration, in King County, Washington, under the Construction Arbitration Rules of the American Arbitration Association (AAA) in effect on the date hereof, as modified by this Warranty.[42]
¶27 Contractual and common law warranties are subject to arbitration. WCA warranties, however, are not: “[A]ny right or obligation declared by this chapter is enforceable by judicial proceeding.”43 The right to a judicial forum for resolution of WCA warranty disputes cannot be waived.44 The contract warranties are thus arbitrable to the extent they exceed the protections required by RCW 64.34.445, but the statutory right to trial applies to the statutory warranties unless the statute is preempted by the FAA. We must therefore decide whether the purchase and sale transactions involved interstate commerce for purposes of the FAA. We believe they do not, for several reasons.
*188¶28 First, the transaction represented by the contracts here was a “garden variety” Washington real estate deal. It involved a Washington company and Washington residents. No national marketing occurred, no interstate media were used, no out-of-state architects or contractors were involved.
¶29 Second, real property law has historically been the law of each state.45 The sale of property, including the requirements for and interpretation of purchase agreements, is entirely governed by state law.
¶30 Third, the warranties in question arise entirely from state law. Unlike Citizens Bank and Allied-Bruce, where the very subject matter of the contracts involved interstate commerce, here the issues are confined to claims founded in warranties created by the Washington Legislature.
¶31 Fourth, these transactions have none of the earmarks of an economic activity that in the aggregate would represent a general practice subject to federal control. The Company offers no authority holding that local real estate transactions represent such a practice, or that warranties required by state law for state condominium projects represent such a practice, or that local regulation of real estate transactions can constitute an economic activity that in the aggregate would represent a general practice subject to federal control. The Company relies upon a single fact: that construction materials came from outside Washington State. In some cases, this is adequate for FAA preemption. Here, it is not.
¶32 Where the issue is federal regulation of the business itself — for example, enforcement of the rights of employees to nondiscriminatory and healthy workplaces — the “transaction” involves the internal operation of the business, and its use of materials shipped in interstate commerce is *189enough to characterize that business as affecting commerce for purposes of the FAA.46 In such cases, the question is the applicability of federal regulation to the conduct of the business.
¶33 Where the issue is a private dispute, however, the analysis must identify the transaction involving commerce. In Citizens Bank, the Court reasoned that because the commerce clause gives Congress “the power to regulate local business establishments purchasing substantial quantities of goods that have moved in interstate commerce,” it followed that it also permits regulation of “substantial commercial loan transactions secured by such goods.”47 In Basura,48, construction materials and appliances came from out of state. In neither case, however, was the presence of interstate materials the only interstate aspect of the case.
¶34 Here, the only connection to interstate commerce is that materials from elsewhere were used in construction, and some of those were allegedly unsound or unsuitable, thereby violating the warranty required by RCW 64.34.445 that the condominium be free from defective materials and constructed in accordance with applicable state law. This warranty amounts to a guarantee that the builder has examined the materials used and ensures they are of sound quality and suitable for the use to which they are put, on site, in Washington State. The origin of the materials is irrelevant to the warranty, and the giving of the warranty is not a transaction involving commerce because, in the aggregate or otherwise, it does not represent a general prac*190tice subject to federal control. Whether the condominium declarant violated the warranty is not a dispute involving interstate commerce.
¶35 It has been often observed that the “affects commerce” test is easily met.49 But no court has held that the use of materials from other states is, by itself, sufficient to render a private transaction as one “involving interstate commerce.” Very few services are rendered and very few products are made using exclusively local materials. While the use of goods shipped in interstate commerce may subject a business to substantive federal regulation, a private contract that is entirely local in subject matter, substantive law, and parties does not acquire an interstate character simply because a refrigerator or a brick was manufactured in another state. The condominium owners purchased real property, not building materials, goods, or services. Whatever hold the FAA had or continues to have over the transactions preceding integration of the materials, goods, and services into the real estate does not extend to the sale of the real property interest itself.
¶36 Here, a significant right created by state law is at issue. The legislature of Washington State retains sovereignty over local real estate transactions. Despite its strong policy favoring arbitration, the legislature created warranty rights in condominium purchasers and provided an exclusively judicial remedy. We do not think this legislative determination as to the appropriate forum for adjudicating legislatively created rights is preempted solely because construction materials may have crossed state lines.
¶37 The reach of the commerce clause is broad, but it is not unlimited. We hold that WCA statutory warranty claims are not arbitrable and that contract and common law claims are, and we remand for further proceedings consistent with this opinion.50

RCW 64.34.443(1) specifies that the formal words “warranty” or “guarantee” are not needed to create an express warranty, which arise from any one of the following:
“(a) Any written affirmation of fact or promise which relates to the unit, its use, or rights appurtenant thereto, area improvements to the condominium that would directly benefit the unit, or the right to use or have the benefit of facilities not located in the condominium creates an express warranty that the unit and related rights and uses will conform to the affirmation or promise;
“(b) Any model or written description of the physical characteristics of the condominium at the time the purchase agreement is executed, including plans and specifications of or for improvements, creates an express warranty that the condominium will conform to the model or description except pursuant to RCW 64.34.410(l)(v);
“(c) Any written description of the quantity or extent of the real property comprising the condominium, including plats or surveys, creates an express warranty that the condominium will conform to the description, subject to customary tolerances; and
“(d) A written provision that a buyer may put a unit only to a specified use is an express warranty that the specified use is lawful.”
RCW 64.34.445 provides in pertinent part:
“(1) A declarant and any dealer warrants that a unit will be in at least as good condition at the earlier of the time of the conveyance or delivery of possession as it was at the time of contracting, reasonable wear and tear and damage by casualty or condemnation excepted.
“(2) A declarant and any dealer impliedly warrants that a unit and the common elements in the condominium are suitable for the ordinary uses of real estate of its type and that any improvements made or contracted for by such declarant or dealer will be:
“(a) Free from defective materials;
“(b) Constructed in accordance with sound engineering and construction standards;
“(c) Constructed in a workmanlike manner; and
“(d) Constructed in compliance with all laws then applicable to such improvements.”
The Association’s complaint alleges the creation of express warranties by public offering statement, advertising materials, advertising statements, and *187samples. See Clerk’s Papers at 6. But the warranty addendum limited the warranties to those in the contract. See Clerk’s Papers at 171, 197.
