Clinton Septic Work Needs the Permit Packet Before Digging
Clinton County points septic installation, replacement, and re-engineering work to the health department construction permit packet.

A rural house in Clinton County can look simple from the road, but the septic system under the yard is not a handshake project. For installation, replacement, or re-engineering work, the county health department is the permit door before anyone starts digging.
The permit packet is more than a blank form. It includes instructions, percolation test forms, a soil test referral listing, the construction permit application, and more. That tells you the order of operations: soil and design questions belong near the front, not after a contractor is ready to bring equipment onto the lawn.
For a buyer, seller, or homeowner, keep the system sketch, age of the tank, pumping records, prior permits, test results, and contractor notes together. If the property is near water, ask about any current replacement-fund program separately instead of assuming grant help applies. Also write down which person is handling the health department call, because septic paperwork can get messy when the owner, buyer, realtor, and contractor all think someone else has it.
For the actual call, Clinton County lists its Environmental Health & Safety Division at 135 Margaret Street in Plattsburgh, with phone 518-565-4870. The friendly version is simple: call early, keep the paperwork in one folder, and do not let the shovel be the thing that starts the permit conversation.
