Housing allowances are available to service members and their families to help cover the cost of housing in the civilian community. Allowances vary by duty station and change each year. Be sure to find out exactly what is available to you before making a decision on the type of housing you believe you can afford and whether to live on or off the installation. Your Relocation Assistance Program (RAP) office can help you apply for housing allowances, as well as relocation allowances, in addition to other services offered. You can also visit the Department of Defense (DoD) Defense Travel Management Office to find current allowance tables, per diem rates, and tools to help you plan.
