Call 811 First
Texas Utilities Code chapter 251 sets the notice window. Tell the 811 center at least 48 hours before you dig, not counting weekends and holidays, and no more than 14 days before.
| Day You Give Notice | Earliest Dig |
|---|---|
| Monday | Wednesday |
| Thursday | Monday |
| Saturday | Tuesday |
The Texas811 FAQ says marking public lines is free. Private lines, like a wire to a shed or a yard light, are on you.
Ask Your HOA
If you have an HOA, ask for its building rules and its approval form. Most want a drawing, the size and the colors. City approval does not replace HOA approval.
Confirm You Are In Austin
Check that your address is inside Austin city limits. Homes outside the city follow other rules, and the five tests do not apply there. Austin builds to the 2024 code books, listed on its building technical codes page, so do not copy deck rules from a suburb.
A Short Checklist
- Run the five question permit check
- Add up your lot cover
- Measure any tree 19 inches or more across
- Get HOA approval in writing
- Call 811 at least 48 hours ahead
