What happened
On August 7, 2026, Builders FirstSource, Inc. filed a data breach notification with the Office of the Massachusetts Attorney General reporting a data security incident that involved personal information held by the company. Builders FirstSource is a publicly traded building products manufacturer and supplier headquartered in Irving, Texas, with roughly 28,000 employees and operations across the United States. The filing reports that Social Security numbers and financial account information were among the data elements involved, and that 8 Massachusetts residents were affected. No figure for the total number of individuals affected nationwide has been made public.
The company began mailing written notification letters to affected individuals, each of which identifies the specific data elements involved for that recipient. The letters state that Builders FirstSource has arranged two years of complimentary access to Epiq's Privacy Solutions ID credit monitoring, which includes three-bureau credit monitoring, Social Security number monitoring, dark web monitoring, identity restoration services, and up to $1 million in identity theft expense reimbursement. Each letter contains an individual activation code and an enrollment deadline. The company also says it has taken additional steps to enhance its existing security measures, and it has set up a dedicated helpline at 888-650-3658.
The public filing does not state when the incident occurred, when it was discovered, or what caused it. Because Social Security numbers and financial account information carry a long-term risk of identity theft and account fraud, and because that risk does not expire when a credit monitoring subscription does, Dapeer Law is evaluating whether Builders FirstSource maintained reasonable data security safeguards and whether notice was provided within the time required by applicable state breach notification statutes.

Common questions
I received a data breach letter from Builders FirstSource. What should I do? +
Keep the breach notice letter from Builders FirstSource. It lists the specific data elements involved for you and contains your Epiq Privacy Solutions ID activation code, and you may need it if you pursue legal remedies. Enroll in the two years of complimentary credit monitoring at www.privacysolutionsid.com before the enrollment deadline in your letter, then review your bank and credit card statements for unrecognized charges. Because Social Security numbers are reported to be involved, consider placing a free fraud alert or security freeze with Equifax, Experian, and TransUnion, and request your free credit reports at AnnualCreditReport.com. If you find confirmed identity theft, report it to the FTC at IdentityTheft.gov and to local law enforcement. A data breach attorney can review your options at no cost.
Am I eligible to join a class action against Builders FirstSource? +
You likely qualify for a free case evaluation if you received a written notification letter from Builders FirstSource, Inc. about this incident. Eligibility for any class action will depend on factors such as your state of residence, the categories of information involved for you (the Massachusetts filing reports Social Security numbers and financial account information), and whether you have experienced any resulting harm or out-of-pocket loss. An attorney can review your notice letter and confirm where you stand at no cost.
How much money could I receive from a class action lawsuit? +
Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount. No payout is guaranteed, and this investigation has not yet resulted in a settlement.
What personal information was exposed in the breach? +
The report Builders FirstSource filed with the Massachusetts Attorney General states that Social Security numbers and financial account information were among the data elements involved. The sample notice letter is written to name each recipient's specific data elements individually, so the exact combination of information may differ from person to person. Review your own letter for the elements listed for you. Dapeer Law is continuing to evaluate whether other categories of information were also affected.
Did Builders FirstSource offer free credit monitoring? +
Yes. Builders FirstSource is offering affected individuals two years (24 months) of complimentary access to Epiq's Privacy Solutions ID service. The product includes three-bureau credit monitoring, annual three-bureau credit reports and VantageScores, Social Security number monitoring, dark web monitoring, credit lock, identity restoration support, and up to $1 million in identity theft expense reimbursement with a $0 deductible. Enrollment instructions, an activation code, and a deadline are in the notice letter, and Epiq's support line is 866-675-2006. Accepting the free monitoring does not waive your right to pursue legal action against Builders FirstSource.
How many people were affected by the Builders FirstSource breach? +
The Massachusetts Attorney General filing lists 8 Massachusetts residents as affected. That figure covers Massachusetts only. Builders FirstSource operates nationwide and has not publicly disclosed a total number of affected individuals or a list of other states where notice was given. This page will be updated as additional filings or figures become available.
Is there a deadline to take legal action? +
Yes. Statutes of limitations for data breach claims vary by state and legal theory, typically ranging from one to six years. Waiting can permanently bar your claim. Contact us as soon as possible for a free evaluation.
How do I get a copy of the official breach notice? +
