Areas of Oak Hill within Austin city limits are served by the Austin Fire Department (AFD). The first AFD fire station specifically purposed to serve the Oak Hill area was constructed in August 1999. However, Oak Hill is also served by the Oak Hill Volunteer Fire Department, which was founded in April 1968. The fire department was originally assigned to an area "...from Brodie Lane to Barton Creek, and from Sunset Valley to Dripping Springs." However, in 1992, the expansion of Austin's city boundaries limited the fire department's coverage area to unincorporated regions of Travis County. Today, the department serves 22,000 people in a region in the southwestern part of the county.
