If you sell or do home improvement work on homes in New Jersey, you must register your business with the New Jersey Division of Consumer Affairs every year, unless the law exempts you. Registration needs liability insurance, workers' compensation unless you are exempt, a new "additional security" such as a bond, and a fee. This guide sets out who must register, what it costs, what changed when the law was amended, and the rules that follow you after you register. Everything here comes from the Division's own pages, read on October 31, 2026. It is a summary, not legal advice, so check the Division's pages before you apply.
What counts as a home improvement
New Jersey's law is the Contractors' Business Registration Act, and the state calls a registered business a home improvement contractor business, or HICB. The Division says home improvements include "the remodeling, painting, repairing, renovating of, and making of additions to residential property," and that this covers garages, basements, driveways, swimming pools, fences and landscaping on the property, as well as work on central heating and air conditioning, insulation, siding, carpeting and flooring (NJ Division of Consumer Affairs FAQ).
The Division's main page adds patios, porches, windows, doors, cabinets, kitchens, bathrooms, finished basements, basement waterproofing, and roofing (NJ Division of Consumer Affairs). Building a new home is not a home improvement under the Act.
Who must register
The Division's answers are blunt:
- Any business that makes or sells home improvements, including a sole proprietor.
- Part-time and side-job contractors. The Act applies whether the work is full time or part time.
- Subcontractors. A subcontractor paid by the general contractor must register, even if it never signs a contract with the homeowner.
- Out-of-state contractors who work on homes in New Jersey.
The Act covers existing homes, single or multi-family, and commercial buildings being converted into homes. It does not cover property used for commercial purposes, though other state rules may apply there (NJ Division of Consumer Affairs FAQ).
Who is exempt
The Division lists these exemptions, among others (NJ Division of Consumer Affairs FAQ):
- new home builders registered with the Department of Community Affairs
- people working on property they own, or that a family member, a charity or a nonprofit owns
- people licensed by a professional board, or another state agency, working within the scope of that license
- employees of a community association or cooperative
- public utilities
- home repair contractors, financing agencies and their salespeople
- very large home improvement retailers and their employees
The licensed-trade exemption matters. If you hold a state license for your trade and the job is within that license, you may not need a separate registration for it. Work outside that license is a different question, so check before you assume you are covered.
What you need to register
To register, and to stay registered, the Division says a business must (NJ Division of Consumer Affairs FAQ):
- submit the Division's application form with the required documents
- file proof of commercial general liability insurance of at least $500,000 per occurrence (NJ Division of Consumer Affairs FAQ)
- file proof of workers' compensation insurance, unless the law exempts you
- file proof of "additional security"
- pay the fee
New applications and reinstatements are paper forms, sent by mail or delivered in person. Renewals are online only.
The additional security rule
The newest requirement came from amendments to the Act (P.L. 2023, c.237). Every registered business, new or renewing, must keep "additional security" in place for as long as it is registered. It can be a compliance bond from a surety company, an irrevocable letter of credit from a bank, or other security the Division accepts.
The minimum depends on the size of your contracts (NJ Division of Consumer Affairs FAQ):
| Your contracts | Minimum security |
|---|---|
| Under $10,000 each, or under $150,000 total in the last 12 months | $10,000 (NJ DCA) |
| $10,000 to $120,000 each, or $150,000 to $750,000 in the last 12 months | $25,000 (NJ DCA) |
| Over $120,000 each, or over $750,000 in the last 12 months | $50,000 (NJ DCA) |
The amount in the table is how much security you must hold, not what it costs you. A surety charges a premium for a bond, and that price is set by the surety, so get quotes. A few details from the Division:
- One security covers all your jobs. You do not need one per contract, client or town.
- The security must be dated on or before the day you submit it. A future date gets rejected.
- If a claim is paid and the security drops below the minimum, you must top it back up.
Fees and renewal dates
The Division lists these non-refundable fees (NJ Division of Consumer Affairs FAQ):
- Initial application: $110 (NJ DCA)
- Renewal by March 31: $90 (NJ DCA)
- Late renewal, April 1 to April 30: $115 (NJ DCA)
- Reinstatement, after April 30: $140 (NJ DCA)
Every registration renews by March 31 each year, whenever you first registered. The Division says renewals open online around January 15, and a registration that is not renewed is changed to expired around May 1 (NJ Division of Consumer Affairs: applications). Put the renewal on your calendar for January.
What happens if you skip it
An unregistered business, including one that let its registration lapse, may not sell or make home improvements in New Jersey. The Division says civil penalties can reach $10,000 for a first offense and $20,000 for each later one (NJ Division of Consumer Affairs FAQ). Working without a registration can also lead to a denied registration later, and a knowing violation can be a fourth-degree crime.
Rules after you register
Two rules the Division highlights apply to every registered business (NJ Division of Consumer Affairs FAQ):
- Written contracts for home improvement jobs that cost more than $500 (NJ DCA).
- Show your registration number at your place of business, in all advertising, on business cards, on your work vehicles and on all business documents.
Advertising includes your website and your Google Business Profile. Put the number in your site's footer and on your estimates and invoices, so it is everywhere a homeowner checks.
