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](https://www.nj.gov/dca/codes/resources/leadpaint.shtml)). Lead inspections are optional for most owner-occupied sales, but buyers of pre-1978 homes get a federal 10-day opportunity to test.

181 current contractors (4 expired entries dropped).
