How do I check a New Jersey contractor's registration?

New Jersey requires Home Improvement Contractor (HIC) registration through the Division of Consumer Affairs (DCA) for any contractor performing residential home improvement work. Search at njconsumeraffairs.gov → License Verification. Enter the HIC registration number or business name. Confirm Active status, business address matches, and no recent disciplinary actions. Electrical, plumbing, and HVAC are licensed separately through their respective NJ state boards.

Does New Jersey license general contractors?

New Jersey "registers" home improvement contractors rather than licensing them — the HIC system tests business compliance (registration, insurance, written contracts) rather than trade competence. For electrical, plumbing, and HVAC, NJ has separate state licensing through the Board of Examiners of Electrical Contractors, Board of Master Plumbers, and Board of Master HVACR Contractors. For a senior project involving multiple trades, verify the GC's HIC registration AND each trade subcontractor's state license.

What is New Jersey's $500 threshold?

New Jersey law requires HIC registration AND a written contract for any residential home improvement job exceeding $500. The written contract requirement is one of the most senior-protective in the country — it must include the HIC number, total price, detailed scope, payment schedule, completion date, three-day right-to-cancel notice, and a copy of the contractor's insurance certificate. Verbal or below-threshold work has no DCA recourse.

What insurance must an NJ contractor carry?

HIC registration requires proof of general liability insurance with minimum coverage of $500,000 per occurrence, plus the contractor must include a copy of the COI in any contract over $500. This is a notable consumer protection — you receive insurance proof at signing, not after. For senior projects, also request workers compensation verification (call the carrier directly) and request $1 million GL for any project over $10,000.

What contractor scams target New Jersey seniors?

Three patterns. (1) Post-coastal-storm contractors — Sandy's lasting effect on New Jersey shore communities means hurricane and Nor'easter season brings out-of-state storm chasers targeting senior homeowners. (2) Pine Barrens / suburban driveway sealing crews in spring/summer, especially in retirement-heavy Ocean and Monmouth counties. (3) Furnace/heating system pitches in winter — door-to-door "your furnace is unsafe" scams target North Jersey senior neighborhoods. New Jersey AG and DCA Office of Consumer Protection Senior Citizens Bureau pursue these aggressively.

How do I report a bad contractor in New Jersey?

File a complaint with the NJ Division of Consumer Affairs at njconsumeraffairs.gov → File a Complaint. DCA can investigate HIC violations, fine up to $10,000 per violation, suspend or revoke registration, and refer egregious cases for criminal prosecution. New Jersey has a Senior Citizens Consumer Fraud statute that enhances penalties for fraud against people 60+ by up to 50%. The DCA complaint is free.

Is hiring an unregistered NJ contractor illegal?

For residential home improvement work over $500, yes — both the contractor and homeowner can be in violation. Hiring unregistered eliminates DCA recourse, voids the written-contract protections, and exposes you to liens and insurance gaps. New Jersey enforces unregistered contracting aggressively, especially after disasters. For any senior project over $500, verify HIC registration at njconsumeraffairs.gov before signing.

New Jersey Contractor Registration (HIC/DCA) 2026

The short version: New Jersey requires HIC registration through the Division of Consumer Affairs (DCA) for any residential home improvement contractor. Verify at njconsumeraffairs.gov → License Verification. NJ has one of the strongest written-contract rules in the country: any job over $500 requires a written contract with HIC number, scope, payment schedule, three-day rescission, AND a copy of the contractor’s insurance certificate. Electrical / plumbing / HVAC are licensed separately. Senior Citizens Consumer Fraud statute adds up to 50% enhanced penalties for fraud against people 60+.

New Jersey: registration + strong contract law

New Jersey “registers” home improvement contractors through the Division of Consumer Affairs (DCA) rather than licensing them on competence. But what NJ lacks in trade-competence testing, it makes up for with one of the strongest written-contract regimes in the country — the Home Improvement Contractor Act mandates specific contract terms for any job over $500, including a mandatory insurance certificate at signing.²

For senior homeowners, this contract regime is the real protection: the moment of signing is when you have leverage, and NJ law forces the contractor to put concrete information in writing before you commit.

This is the NJ-specific companion to our national state contractor license lookup guide. For the master pre-hire workflow, see How to Find a Senior-Friendly Contractor.

How to verify: njconsumeraffairs.gov

To verify: go to njconsumeraffairs.gov → License Verification.¹ Enter the HIC registration number, business name, or contractor name.

What to check:

Status Active (not expired, suspended, revoked)
HIC registration number matches the contractor’s quote
Business name matches across documents
Business address matches what they gave you
Disciplinary history — recent DCA actions

A contractor without an active HIC registration cannot legally perform residential home improvement work over $500 in NJ.

NJ’s $500 written-contract regime

For any home improvement job over $500, New Jersey law requires a written contract that includes:²

HIC registration number prominently displayed
Total contract price with itemized scope
Detailed scope of work (locations, dimensions, materials)
Payment schedule with milestone definitions
Start date and substantial completion date
3-day right-to-cancel notice in required font size
Copy of the contractor’s Certificate of Insurance attached

The mandatory-COI-at-signing rule is unusual and senior-protective — you receive proof of insurance the moment you sign, not weeks later when something has gone wrong. Refuse to sign any contract over $500 missing these elements.

For the broader contract-clause checklist, see Reading the Contract: 7 Clauses to Watch.

Trades are separately licensed

For electrical, plumbing, and HVAC sub-work, NJ has separate state boards (all under DCA):

Board of Examiners of Electrical Contractors — for senior electrical work
Board of Master Plumbers — for plumbing
Board of Master HVACR Contractors — for heat pump installs and HVAC

All searchable at njconsumeraffairs.gov. The HIC registration does NOT cover state-licensed trade work — verify each board separately.

NJ insurance requirement

HIC registration requires:

General liability: $500,000 per occurrence minimum
COI attached to every contract over $500 (unique to NJ)

For senior projects over $10K, the $500K floor is light — request a current COI showing $1 million GL and verify directly with the carrier (call a number you find independently). Workers compensation is required if the contractor has employees. See Contractor Insurance & Bonding.

NJ senior scam patterns

Sandy’s lasting shadow — Shore counties (Ocean, Monmouth, Atlantic, Cape May) see persistent post-storm contractor activity. Hurricane and Nor’easter seasons bring out-of-state storm chasers targeting senior coastal homeowners. Never sign over insurance proceeds (AOB-style transfers).
Furnace pitches — North Jersey winters drive door-to-door furnace replacement scams targeting senior neighborhoods. Verify the HVACR board license before any furnace work.
Retirement-county driveway crews — Ocean and Monmouth counties (large retirement populations) see active spring/summer traveling driveway sealing crews.
NJ AG Senior Brigade + DCA Senior Citizens Bureau — both actively pursue elder home-repair fraud.³ Senior Citizens Consumer Fraud statute adds up to 50% enhanced civil and criminal penalties for fraud against people 60+.

If something goes wrong

HIC violations or unregistered contracting: file at njconsumeraffairs.gov → File a Complaint. DCA can fine up to $10,000 per violation, suspend or revoke registration, refer for criminal prosecution.
Trade license issues (electrical, plumbing, HVACR): file at the relevant board, also accessed via njconsumeraffairs.gov.
Senior consumer fraud: NJ AG Senior Brigade + DCA Senior Citizens Bureau. Senior Citizens Consumer Fraud statute applies.
Elder financial abuse: also contact your county Adult Protective Services.
