Why it matters
Book the inspection before you set a closing date.
In Massachusetts, the local fire department must certify smoke and carbon monoxide alarms before most homes are sold. New Jersey requires a certificate covering smoke alarms, CO alarms and a portable fire extinguisher before a one- or two-family home is sold or leased. Busy departments can be booked weeks out.
Fees, scheduling rules and what passes vary by town and by the age of the house. Our town tables link to each fire department's own page so you can confirm the fee, apply online and prepare before the inspector arrives.
