Getting the certificate in Trenton City
- Confirm the building was built before 1978 and no exemption applies.
- Book the inspection, either through Trenton City's own lead inspection program or with a certified lead evaluation firm you hire. If you hire a firm, it sends Trenton City a copy of any certificate it issues.
- If the inspector finds lead hazards, have them fixed (interim controls or abatement) and re-inspected.
- Keep the lead-safe certificate, report each tenant turnover to Trenton City, and book the next inspection before the certificate's three years run out.
