Securing payment for labor, materials, or equipment is a priority for every contractor and subcontractor working in New Jersey. The New Jersey Construction Lien Law grants unpaid parties the right to place a lien directly against the improved real estate. What many contractors do not realize is that the procedures, prerequisites, and timelines differ significantly depending on whether the project is commercial or residential. Confusing the two can result in an invalid filing and the loss of lien rights entirely.
Filing deadlines
The first major distinction involves timing. On commercial projects, contractors, subcontractors, and suppliers have 90 days from the date the last work, services, or materials were delivered to file a lien claim directly with the county clerk. On residential projects, the final lien claim must still be filed within 120 days of last work, but the process before that filing is more involved and cannot be skipped.
Mandatory arbitration for residential liens
New Jersey law imposes consumer protections for residential property owners that add required steps before a lien can be recorded. A contractor seeking to lien a residential property must first file a Notice of Unpaid Balance and Right to File Lien, known as a NUB. The residential lien process requires these steps in order:
- File the NUB with the county clerk within 60 days of the last date work or materials were provided
- Serve the NUB on the property owner and primary contractor within 10 business days of filing
- File a demand for expedited arbitration with the American Arbitration Association simultaneously with the NUB filing
- Receive a favorable arbitration determination, which must be completed within 30 days
- Record the actual lien claim within the overall 120-day statutory window
On commercial projects, no NUB or arbitration is required. Contractors proceed directly to recording the lien within 90 days.
Lien fund calculation
The maximum enforceable lien amount is also calculated differently. On commercial projects, the lien cannot exceed the unearned balance of the prime contract at the time the lien is filed. On residential projects, the lien fund is capped by the unpaid balance of the prime contract at the time the owner receives written notice of the NUB. If the homeowner paid the primary contractor in full before receiving NUB notice, a subcontractor’s lien fund may be effectively zero.
Consequences of filing incorrectly
Filing a commercial lien on a residential project, or missing the 60-day NUB deadline, violates the New Jersey Construction Lien Law. A procedurally improper or exaggerated lien can result in court sanctions, forfeiture of lien rights, and liability for the property owner’s attorney fees.
Protecting your payment rights
Because the procedural windows run quickly, identifying the correct property classification and acting promptly when payment stalls is essential. Contact a New Jersey construction lien attorney who can help ensure your lien rights are properly preserved before a deadline passes.
