NHDES · New Hampshire property records
Find the NHDES record—even when OneStop is empty.
Start with the property. We turn its address, owner history, and map-and-lot clues into the right OneStop, archive, or town-office route.
A usable approval, plan, or a documented next step—not another list of government links.

Bring the clues.
We’ll prepare the route.
Search OneStop first. Most post-1986 approvals appear there; older approvals and many pre-2015 plans may require the archive request or the town file.

Ready-to-review wording
Use a complete request the first time.
This wording is prepared from the clues above. Review it before using it; copying it does not submit anything.
When the easy search breaks
No result is
not one conclusion.
A blank OneStop result does not establish that no record exists. Older approvals, pre-digital plans, owner-name changes, and town copies create separate search paths.
- 01
Search OneStop with the strongest property identifiers.
- 02
If the plan is not attached, move to the archive request and town file.
- 03
Read approval type, design flow, bedrooms, tank, and disposal area without treating an old plan as a current inspection.
What becomes useful
Two approvals can matter
A New Hampshire file may contain both Construction Approval and Operational Approval. We separate them before summarizing what the record actually establishes.
- Construction Approval
- Operational Approval
- Approved septic plan
