New Jersey shore rentals touch plumbing rules in three places: the smoke alarm, carbon monoxide alarm and extinguisher certificate required at a change of occupancy, well testing every five years for rentals on private wells, and any rental licence or inspection your town runs.

N.J.A.C. 5:70-2.3 requires a certificate of smoke alarm, carbon monoxide alarm and portable fire extinguisher compliance when a one- or two-family home changes occupancy. Towns handle seasonal rentals differently: some issue one certificate for a 12-month period whatever the number of tenancies, and some exclude the extinguisher item for seasonal units. Ask your town's fire official.
When the rental gets its drinking water from a private well. The landlord tests every five years and gives tenants a written copy of the results. Most island houses are on public water and aren't covered.
Many shore towns run rental registration or inspection programs. Ask the town clerk or code enforcement office what is checked; plumbing items such as working hot water and no leaks are common.
