New Jersey › Septic inspection requirements

Is a Septic Inspection Required to Sell a House in NJ?

Short answer: there is no statewide law requiring a septic inspection to sell a home in New Jersey — but many towns require one locally, and it’s strongly recommended in every sale.

The statewide picture

New Jersey does not have a single state mandate forcing a septic inspection at the point of sale. Instead, two things drive whether you’ll need one:

• Local ordinances. Many municipalities require a septic inspection within a set window before closing (for example, some Burlington County townships such as Evesham require an inspection within 12 months of the sale). These rules are set town by town.
• Lenders and buyers. Even where no ordinance applies, buyers and mortgage lenders routinely require an inspection before closing to avoid inheriting a failed system.

When an inspection is done for a property transfer, it must follow the state protocol at N.J.A.C. 7:9A-12.6. The NJDEP recommends that every buyer of a septic-served property get one regardless of local rules.

What a NJ septic inspection covers

A transfer inspection typically locates and opens the tank, pumps it to inspect the interior and baffles, checks inlet/outlet flow, and evaluates the drain (disposal) field for signs of failure — documented with photos and a written report.

How long it lasts & what if it fails

A NJ septic inspection is generally good for about two years. If the system fails, sellers usually repair and re-inspect, negotiate a price reduction, or give the buyer a credit at closing to cover the repair.

Find a septic inspector by county

Browse providers in your county, then confirm your specific town’s requirement with your local health department.

We do not publish a town-by-town “required: yes/no” claim, because these ordinances change and vary across NJ’s 564 municipalities. Always confirm the current rule with your municipal or county health department before listing.
