How to get a copy of your septic record in Galveston County
1
Identify your property markers
Septic records are filed under the parcel identification number (APN) or original subdivision lot number rather than resident names. Obtain your parcel ID from your property tax statement or county deed.
2
Check the official repository
Contact Galveston County Environmental Health Department directly. Most records are retrieved within 1 to 3 business days.
3
Request an as-built drawing and inspection card
Ensure you request the as-built construction diagram, which shows exact footages from house corners to the septic tank lid, distribution box, and lateral absorption trenches.
