Basic Allowance for Housing

BAH is an allowance to offset the cost of housing when you do not receive government-provided housing. Your BAH depends upon your location, pay grade and whether you have dependents. BAH rates are set by surveying the cost of rental properties in each geographic location. Therefore, BAH rates in high-cost areas will be much greater than those in low-cost areas. BAH rates are published on the Defense Travel Management Office Web page.
