How the new jersey resale certificate process works

Every New Jersey home sale needs a certificate showing working smoke alarms and carbon monoxide alarms, issued by the local fire official. Many towns also require their own resale certificate of occupancy (CO or CCO), which can add a property maintenance inspection.

  1. Apply to the local fire official, or the construction office, as soon as you list. The state fee is lowest when you apply more than 10 business days before closing.
  2. Install smoke alarms on every level and outside sleeping areas, and a carbon monoxide alarm near sleeping areas if the home has fuel-burning appliances or an attached garage.
  3. If the town also requires a resale CO, schedule that inspection and fix the listed items, or ask about a temporary certificate or buyer assumption.
  4. Give the certificates to the title company before closing.
