What must a New Jersey contractor website display?
In New Jersey a website counts as advertising, so the display rules for your trade apply to it. Home improvement contractors must show the registration number on all advertisements distributed in the State. Plumbing, electrical and HVACR contractors must each include prescribed wording plus the license or permit number. The required phrase differs by trade, and a generic template will not add it for you.
This guide is for an owner of a plumbing, electrical, HVACR, or home improvement service business in Ocean County or Monmouth County, New Jersey, who is buying a first website, rebuilding an old one, or fixing a site before it goes live. Identify the board governing the work your business advertises. A mixed-scope Shore business that does both HVACR and plumbing may face two distinct rules.
The issue is practical on the Jersey Shore. After a nor'easter, barrier-island and bayfront homeowners often need help quickly, while out-of-state seasonal-rental owners in Toms River and Brick may vet a contractor online before driving down. A displayed registration number can be checked against the State register, which is why its absence is worth noticing after a coastal storm.
Four trades, four website display rules
The four New Jersey trade rules below use different labels, and two of them require an address in advertising as well. Copying an HVACR license label onto an electrical company's site, or putting an individual electrical license number where the business permit number belongs, can leave the page inconsistent with the governing rule.
The table applies the advertising language to a website without inventing a screen size, font size, or a required footer location. The practical approach is to put the required information somewhere a visitor can find on every advertising page, then have the business or its attorney confirm that the final presentation fits its actual scope and credentials.
| Trade and governing rule | Exact wording prescribed for advertising | What that means for the website | Citation |
|---|---|---|---|
| Home improvement, N.J.A.C. 13:45A-17.11 | No specific wording is prescribed for advertising. The registration number must be displayed prominently. "HIC reg. #" is a vehicle-marking string. | Show the contractor's New Jersey home improvement registration number prominently in website advertising. | N.J.A.C. 13:45A-17.11(d)2, (e) |
| Plumbing, N.J.A.C. 13:32-3.1 | "Plumbing license number" or "Plumbing Lic. #". Conditional: if a master plumber subcontracts, or intends to subcontract, more than one third of the plumbing work in a calendar year, including the previous calendar year, all advertising must also state: "A substantial part of the work which we undertake may be performed by independent licensed plumbing subcontractors." | Include the licensed master plumber's name, New Jersey business street address, and the labeled license number. Add the conditional disclosure to all advertising only above the one third threshold. | N.J.A.C. 13:32-3.1(c), (e) |
| Electrical, N.J.A.C. 13:31-1.5 | "Electrical Contractor business permit number" or "Electrical Contractor Bus. Permit #" | Include the licensed electrical contractor's name, the qualifying licensee's business street address, and the labeled business permit number. | N.J.A.C. 13:31-1.5(b) |
| HVACR, N.J.A.C. 13:32A-5.1 | "Master HVACR contractor license number" or "Master HVACR contractor Lic. #". Conditional: if a master HVACR contractor subcontracts, or intends to subcontract, more than one third of the HVACR work in a calendar year, including the previous calendar year, all advertising must also state: "A substantial part of the HVACR work which we undertake may be subcontracted to independent licensed HVACR contractors." | Include the master HVACR contractor's name and the labeled master HVACR contractor license number. Add the conditional disclosure to all advertising only above the one third threshold. | N.J.A.C. 13:32A-5.1(c), (e) |
Put the exact trade language in the site plan
Website placement for a New Jersey service business should start with a written credential block, not a last-minute footer edit. Give the web provider the name of the master plumber, master HVACR contractor, or licensed electrical contractor named by the applicable rule, together with the correct number and the New Jersey street address when the rule requires one.
A consistent footer can be useful, but do not assume it solves every page without checking the final website. A service page for emergency plumbing, a paid landing page for air-conditioning repair, and a storm-response page can all function as advertising. The required wording should survive mobile layouts, page redesigns, form templates, and future vendor changes.
HVACR deserves special attention because the rule names the master HVACR contractor and prescribes the license wording. The same rule says that a master HVACR contractor whose name, office address, or license number appears in an advertisement is presumed responsible for its content and character. That is a reason to review the live page, not just the draft in a designer's preview.
Website rules are not vehicle-marking rules
Vehicle-marking requirements for New Jersey trade contractors are separate from website display requirements. The home improvement, plumbing, electrical, and HVACR rules include vehicle provisions, and several specify lettering heights for the name or credential. Those measurements describe commercial vehicles, not website type size, responsive breakpoints, or a footer's visual design.
Home improvement contractors also have requirements for business documents, contracts, and consumer correspondence that are not automatically website requirements. For example, the home improvement rule specifies a Division toll-free notice for invoices, contracts, and correspondence. Keep a website compliance review separate from a document and vehicle review so a rule from one medium is not silently applied to another.
That distinction matters after salt air and coastal weather wear down vans, signs, and job-site materials. A contractor updating a faded vehicle wrap after a Shore winter should check the vehicle rule, while a contractor rebuilding a website for summer turnover should check the advertising rule. Both tasks involve credentials, but the required presentation is not interchangeable.
A practical handoff for your website rebuild
A website rebuild for an Ocean County or Monmouth County trade business should include credential review before the site launches. The owner should supply the governing trade rule, the exact person or business named by that rule, the applicable number, and the New Jersey address where required. The designer should identify every reusable template where that information will appear.
Keep the budget discussion separate from the display-rule work. /blog/nj-contractor-marketing-budget/ covers the marketing-budget decision; this page addresses what advertising on the site needs to say. Before hiring a provider, use /blog/questions-to-ask-nj-web-designer/ to ask who enters regulated information, who reviews it after launch, and how future edits are handled.
Website control affects compliance as well as convenience. If a vendor controls the domain, footer, forms, or page templates, confirm that your business can correct a credential promptly after a renewal, personnel change, or scope change. /blog/who-owns-my-website/ explains the ownership questions to settle before a rebuild, and /claim/ is the next step when you are ready to review a trade site.
- Name every regulated service the business advertises, then match each service to its governing board and rule.
- Give the web provider the exact approved wording, number, name, and address rather than asking for a generic license line.
- Review the live mobile site, service pages, campaign pages, footer, contact page, and forms after publication.
- Record who can update the information and review it again when a credential, qualifying person, or business address changes.
Frequently asked questions
These answers address common website-display decisions for Ocean County and Monmouth County service-business owners. They are information, not legal advice. Read the rule that governs your actual scope of work and ask qualified legal or licensing guidance when the business has a mixed scope, a subcontracting arrangement, or an unusual ownership structure.
Is a license number by itself enough in a website footer?
Not necessarily. The plumbing, HVACR, and electrical rules prescribe labels for the number, and plumbing and electrical advertising also call for specified names and New Jersey business street addresses. A generic number without the applicable label can omit information the rule describes.
Which number does an electrical contractor website show?
The electrical rule calls for the business permit number of the business permit holder, with either "Electrical Contractor business permit number" or "Electrical Contractor Bus. Permit #." It also calls for the licensed electrical contractor's name and the qualifying licensee's business street address in advertising.
What if my company advertises both plumbing and HVACR work?
Read both rules and plan for both requirements. The plumbing rule calls for its prescribed plumbing license wording, the licensed master plumber's name, and a New Jersey business address. The HVACR rule calls for the master HVACR contractor's name and its different prescribed license wording.
Do vehicle lettering heights apply to my website?
No vehicle lettering height is stated as a website rule in the provisions reviewed here. The measurements in these rules address commercial vehicles. Website advertising still needs the information the applicable advertising provision requires, but it is a separate question from the lettering on a truck or van.
