What Connecticut requires on your site, in ads and on calls

Connecticut does not leave marketing and phone practices to federal law alone. The home improvement statute tells contractors what must appear in their ads and contracts, a state statute sets its own terms for recording phone calls, the telemarketing chapter reaches texts as well as calls, and the tax department lists taxable services that include website work. Each rule below affects a site, a phone setup, an AI receptionist or a mailing list. Federal law applies everywhere, so keep the TCPA guide and the call recording guide open beside this one. Facts below are as of October 2026.

Your registration number goes in every Connecticut ad

If you do home improvement work for homeowners, Connecticut Gen. Stat. § 20-427(a) tells each person engaged in making home improvements to do three things. Show the certificate of registration to anyone who asks, state in any advertisement that you are registered, and include your registration number in any advertisement. The statute does not carve out websites, so treat your home page, service pages, Google Business Profile, truck lettering and paid ads as advertisements and print the number where a visitor sees it, for example in the footer and on the contact page.

The same section lists things nobody may do, including offering to make a home improvement without a current certificate, using an expired or suspended certificate, and implying that registration is the state's endorsement of your workmanship. So a line such as "Registered with the state" is fine only if it is true and current, and "state approved" is a risk. Certificates expire each year on March 31 under § 20-427(f), which makes the website footer worth checking every spring.

The penalties are real. Most violations of § 20-427(b) are class B misdemeanors, a violation of the chapter counts as an unfair or deceptive trade practice, and the Consumer Protection commissioner can impose a civil penalty of up to $1,500 per violation after notice and a hearing. The statute's definition of home improvement (§ 20-419) excludes tree or shrub cutting and stump grinding, and jobs where the total price of everything agreed is $200 or less are outside it as well. The details of who must register are in our Connecticut contractor license guide.

Online quotes become contracts with required terms

A quote tool or booking form is only the start of a home improvement job. Under § 20-429(a), a home improvement contract is not valid or enforceable against the owner unless it is in writing, signed by owner and contractor, and contains the entire agreement. It must also carry the date, your name and address and your registration number, notice of the owner's cancellation rights, a starting date and a completion date. It must be entered into by a registered salesman or registered contractor, and it must disclose other home improvement or new home construction businesses that the owners have been tied to in the previous five years. Each change has to be in writing and signed, and the owner gets a completed copy at signing.

Section 20-429(e) treats every home improvement contract as a home solicitation sale, wherever it is signed. Chapter 740 then requires the contract to include a notice telling the buyer they may cancel before midnight of the third business day after the transaction, plus a separate cancellation form (§ 42-135a). A web form that lets a customer accept a price with a checkbox does not produce that notice, so build the signature and the cancellation notice into your document flow before you take deposits online.

There is also a refund clock. If a customer asks in writing for a refund, no substantial work has been done, and more than thirty days have passed since the start date in the contract (or since the contract date when none is stated), § 20-427(b)(8) requires you to refund within ten days. For the contract basics that apply in every state, see what to put in a service contract.

Recording calls needs a notice in Connecticut

For an oral private telephone call, § 52-570d(a) lets a person record only if one of three things happens. All parties consent, in writing or at the start of the recording. The recording party gives a verbal notice that is itself recorded at the beginning of the call. Or an automatic tone warning device produces a distinct signal repeated about every fifteen seconds. Anyone recorded outside those options can sue, and the statute provides damages and attorney's fees. A business line should follow this civil statute because that is where the lawsuit risk sits.

In practice, the first words of every inbound call should be a recorded line such as "This call may be recorded for quality and scheduling." That works for a front-desk phone, a call-tracking number and an AI receptionist, as long as the notice plays before the conversation and is itself on the recording. Several exceptions in § 52-570d(b) cover recipients of threats or of repeated calls at extremely inconvenient hours, but they are narrow and should not be your policy.

Connecticut telemarketing law reaches calls and texts

Chapter 743m defines a "marketing or sales solicitation" to include communications by telephone call, automated dialer, recorded message, soundboard technology, over-the-top message, and text or media message. Section 42-288a sets conduct rules for sales calls to consumers: calls limited to the hours between 9 a.m. and 8 p.m. local time, identity and purpose disclosed within ten seconds, an immediate offer to end the call or be removed from the list, and a stop within ten seconds when the consumer says so. Telemarketers may not block caller ID or send inaccurate caller information. Subsections (l) and (m) add prior express written consent requirements, and subsection (o) adds a fine of up to $20,000 per violation on top of other penalties.

The statute's definition of consent is stricter than a checked box with no context. Prior express written consent must name the means used to reach the consumer (for example text or media messaging or an automated dialing system), name the phone number, authorize those messages clearly and conspicuously, and carry the consumer's signature. The definition of a marketing solicitation excludes messages to someone who gave that consent, who visited a fixed establishment, or who has an established business relationship with you, which the statute defines as a relationship formed by an application, purchase or transaction that neither side has ended.

The statute also carves out of "telephonic sales call" a call or message sent in response to the consumer's own request or inquiry, and one sent to an existing customer unless that customer has said they no longer want such calls or messages. The chapter is aimed at consumer goods and services bought for personal, family or household use. The statute presumes that a sales call to a Connecticut resident, or to a number with a Connecticut area code, takes place in the state (§ 42-288(c)), wherever you are located. If you text past customers a seasonal reminder, keep the signed consent record, the number, and the date, and honor stop requests quickly. Our TCPA guide covers the federal baseline.

Website services are taxable, card surcharges are banned

The Department of Revenue Services publishes a list of services subject to sales and use tax. It includes services to create, develop, host or maintain all or part of a website purchased by a business for business use, and computer and data processing services more broadly. Your own services may be on the list too: landscaping and horticulture, janitorial, exterminating, painting and lettering, locksmith, maintenance, repair of air conditioning equipment, and certain contractor services to real property. Services to commercial and income-producing property are taxed, while owner-occupied homes with no more than three units fall outside that category. If your own services are on the list, register for the permit before your first invoice and decide how estimates and online payment pages will show the tax. Our state sales tax table compares all 50 states.

Connecticut Gen. Stat. § 42-133ff bars fees that increase the total because of the payment method. The Department of Consumer Protection's page says the law prevents businesses from collecting any fee or charge that increases the total of a transaction when it results from the method of payment used, and credit cards are the common example. So the "3% card fee" line that works in other states should not appear on a Connecticut invoice, online payment page or text-to-pay link. Ask the department or counsel before you advertise a discount for paying another way. Details on payment tools are in online payments for contractors.

The state privacy law now starts at 35,000 consumers

Public Act 25-113 amended the Connecticut Data Privacy Act effective July 1, 2026. Section 42-516 now applies to businesses operating in the state that controlled or processed personal data of 35,000 or more consumers in the preceding year (excluding data used only to complete a payment), that control or process consumers' sensitive data, or that offer personal data for sale. Before the amendment the consumer threshold was 100,000. Sensitive data includes precise geolocation, financial account numbers with access codes, and biometric or genetic data. Most owner-run crews will not reach 35,000 consumers, but the sensitive-data trigger has no volume floor, so check what your website forms, call recordings, customer portal and any location features actually collect.

What this means for your setup

• Website: put your registration number in the footer and on contact and service pages, keep the expiry date on a calendar, and do not show a card fee line on online payments.
• Phone line: play a recording notice at the start of every call before you turn recording on, including on call tracking numbers.
• AI receptionist: script the recorded notice as the first sentence and log consent; see our AI receptionist service and the phone systems page.
• Email and texts: save signed consent with the means and number named, send within 9 a.m. to 8 p.m. for sales calls, and process stop requests the same day.
