Tenant turnover and lead inspections: how the trigger works

August 27, 2026

Turnover means a new tenancy: the old tenant leaves and a new one moves in. Under the law, turnover triggers a lead inspection unless a current lead-safe certificate covers the unit. Certificates are valid two years, so one pass can cover several turnovers.

The three scenarios

New tenant, no current certificate. The inspection must happen before the new tenancy starts. Book as soon as you have a move-out date; 48-hour scheduling makes the gap workable.

New tenant, certificate under 2 years old. No inspection needed. Give the new tenant evidence of the certificate and attach a copy to the lease as an exhibit, which the law requires at turnover (N.J.A.C. 5:28A-3.1). Note the expiration.

Same tenant renews. Not a turnover. Nothing is triggered, but the every-3-years clock keeps running; see deadlines.

Why the certificate changes the economics

In a high-turnover building, inspecting at every tenant change would be expensive. The two-year certificate is the law’s pressure valve: one inspection, then turnovers inside the window are free. For buildings that turn over yearly, keeping the certificate current cuts the inspection count roughly in half.

Turnover questions

Do I have to tell the town when a unit turns over?

Yes. Owners have to inform the municipality of all tenant turnover activity so any required inspection can be scheduled (N.J.A.C. 5:28A-3.1). If you hold a current certificate, the turnover still gets reported; it just does not trigger an inspection.

A roommate moved out and a new one moved in. Turnover?

No, as long as at least one original tenant stays. Under N.J.A.C. 5:28A-1.3, turnover happens only when all existing occupants vacate and new tenants move in.

The unit will sit vacant for a while. When do I inspect?

Any time before the new tenancy starts. Vacant is the easiest time to fix paint and pass.

Can I show and sign a lease before the inspection?

Yes, but the unit should be certified before the tenancy begins. Time the inspection between move-out and move-in.

Move-out date on the calendar?

Book now and the certificate is ready before the new lease starts.
