How long will the annexation process take?
If the area to be annexed includes 100 or more properties with a house on each lot, then the annexation process takes three years. If the area is undeveloped, is commercial property, or has fewer than 100 houses, then the annexation process typically takes six to nine months. However, this time frame varies depending on the complexity of the case, the staff review time required, and the Austin City Council calendar.
