New Rural Structures Need a Williamson County 9-1-1 Address

Put up a new driveway, a barndominium, a workshop, or a second dwelling out in the county and you need a real address for it, not just a mailbox on the road. Anyone who needs an address for telephone service, a utility hookup, or a similar reason contacts Williamson County's Addressing Staff to get one assigned.

The county publishes addressing guidelines for both rural-style and city-style addresses, and a consistent one is what lets an ambulance crew, a meter installer, a delivery driver, and a permit reviewer all find the same gate. A subdivision nickname or 'third place past the cattle guard' won't cut it when seconds count.

Get the address from Williamson County GIS and 9-1-1 Addressing while you're still planning, so it's in hand when you set meters, order service, or name a private road. If the land sits inside a city or a city ETJ, ask whether that city runs its own addressing step on top.
