HSAR (Homeland Security Acquisition Regulation)
HSAR stands for Homeland Security Acquisition Regulation. The HSAR is the Department of Homeland Security supplement to the FAR, found in Title 48 of the Code of Federal Regulations, Chapter 30. It applies when DHS components buy, including FEMA, Customs and Border Protection, TSA, ICE, the Secret Service, and the Coast Guard.
HSAR clauses start with 3052. Many deal with security, such as background checks for contractor employees who need access to DHS facilities or information, and rules for protecting sensitive information. Some DHS offices also use their own internal guidance, so the solicitation is always the final word.
Why it matters to a small contractor
DHS facilities like border stations and Coast Guard bases need janitorial, maintenance, and security work. The HSAR background check rules can add weeks before your crew can start, so plan for that in your staffing and schedule. Ask early what level of employee screening the job needs.
Example
A small HVAC firm wins a maintenance subcontract at a Coast Guard station. The contract includes an HSAR clause requiring employee background checks, so the owner submits paperwork for two technicians a month before the start date.
HSAR: common questions
Which agencies use HSAR?
All Department of Homeland Security components use it, including FEMA, CBP, ICE, TSA, USCIS, the Secret Service, CISA, and the Coast Guard.
Do HSAR clauses flow down to subcontractors?
Many security-related HSAR clauses do flow down. Read each clause, and ask the prime which ones apply to your part of the work.
