Frequently asked questions
How many certified lead evaluation contractors are based outside New Jersey?
24 contractors on the DCA list give an address outside New Jersey. Many work statewide, so ask whether they cover your town. Source: the NJ DCA list of certified lead evaluation contractors.
When does New Jersey require a lead-safe certification inspection?
NJ requires lead-safe certification inspections of most pre-1978 rental units at tenant turnover (P.L.2021, c.182). DCA-certified lead evaluation contractors do these inspections and other lead evaluations (NJ DCA lead-safe certification).
Is a lead inspection required to sell a home in New Jersey?
Not for most owner-occupied sales. Buyers of pre-1978 homes get a 10-day period to do a lead-based paint inspection or risk assessment, which the parties can lengthen, shorten or waive in writing (EPA real estate disclosure rule).
