Kansas rules a contractor's website, phone line and inbox must follow

Most of the rules that shape a contractor's website, phone line and inbox are federal. Kansas adds a short list of its own. This page covers the ones with a Kansas statute behind them, as read on the state's official sites in October 2026. Where Kansas has nothing special to say, we say so and move on.

Roofers must register with the Attorney General, and the registration affects what you can promise online

Kansas does not run a statewide general contractor license, but it does register roofers. Under K.S.A. 50-6,123, no one may act as a roofing contractor in Kansas without a registration certificate from the Attorney General. A roofer without one also cannot bring or maintain a court claim related to the roofing business. The statute sets civil penalties for working without a certificate or while it is suspended or revoked.

The application rules sit in K.S.A. 50-6,125. The applicant files under oath and must be at least 18. The filing includes a certificate of liability insurance for not less than $500,000, proof of workers' compensation coverage or an affidavit of exemption or self-insurance, and a current tax clearance from the Department of Revenue. The insurer must notify the Attorney General if the policy lapses.

Neither section says a registered roofer must print a registration number in ads or on a website. We found no such rule in the statutes we read, so we will not invent one. A roofing page that says "registered with the Kansas Attorney General" should be true on the day it is published, and an expired registration is a reason to take it down. The Attorney General's roofing registration page is where homeowners are pointed to check status, so assume anything on your site will get checked. For the other trades, see our Kansas contractor license guide.

Recording calls in Kansas is one-party consent

K.S.A. 21-6101(a)(1) makes it a breach of privacy to intercept a telephone message without the consent of the sender or the receiver. In practice, either person on the call can agree. A Kansas contractor who is on the call can record it, and that covers a recorded main line, call tracking that records, and an AI receptionist that keeps a recording or transcript. The same statute separately bars hidden recording devices in private places, which is a different question from phone calls. Read it at the Kansas Revisor of Statutes.

The wrinkle is the caller's location. A customer in an all-party state can be protected by that state's law even when your office is in Kansas. The mixed cases are covered in our recording business calls guide, and the call recording table lists every state. A short spoken notice at the start of every call ("this call may be recorded") solves it for both sides and costs nothing. It is a good default for an AI phone line.

The Kansas No-Call Act: the FTC list is the state list

Kansas regulates sales calls through K.S.A. 50-670 and 50-670a, which together make up the Kansas No-Call Act. Three details matter to a service business.

• The list. Under K.S.A. 50-670a, the national registry run by the FTC is designated as the Kansas no-call list. A solicitor must check it before making unsolicited consumer calls and at least every 30 days after, and has up to 30 days to remove a newly registered number.
• Who is exempt. Per K.S.A. 50-670, calls the consumer asked for are exempt, and so are calls about an unfinished contract or debt. So are calls to someone with an established business relationship, defined as a voluntary two-way communication tied to an application, purchase or transaction within the previous 18 months. If that person tells you to stop, you must honor it for five years.
• Call conduct. A solicitor must identify itself and the business it calls for, state the purpose right away, and stop after a negative response. For sales calls it places, a live operator or automated device must answer within 5 seconds and the line must be released within 25 seconds after the consumer hangs up. A prerecorded message may carry identification only, with no advertisement. You may not block your number from caller ID on these calls.

The statute text we read sets no calling hours and does not mention text messages, and neither section creates a telemarketer registration. Violations are treated as unconscionable acts under the Kansas Consumer Protection Act. There is a narrow error defense, available only once in any 12 months. Federal rules still apply on top. Our guide to text and call marketing rules under the TCPA covers the federal side, including consent for texts, which Kansas does not address separately.

For a contractor, the practical result is simple. A past customer from the last 18 months is fair game for a service reminder. A cold list of homeowners is not, unless you scrub it against the registry and keep records of when you did.

In-home sales carry a three-business-day right to cancel

The Kansas Consumer Protection Act includes a door-to-door sales rule in K.S.A. 50-640. A consumer may cancel until midnight of the third business day after signing, and business days exclude Sundays and legal holidays. The rule covers sales of $25 or more, including sales that follow an invitation from the consumer. The seller must hand over a detachable notice of cancellation in duplicate, in 10-point boldface type, and explain the right out loud at signing. A valid cancellation means a refund within 10 business days.

The statute excludes sales conducted entirely by mail or phone. It also excludes repair or maintenance visits the consumer asked for, though extra sales beyond necessary parts are not excluded. A genuine emergency can be waived, but only through a separate, dated, handwritten statement signed by the customer. So the rule bites on a different path: a rep who walks a neighborhood after a storm, or sells an upgrade at the kitchen table. If your online booking form leads to a quote written and signed at the customer's home, have a lawyer look at whether your paperwork needs the cancellation notice. A page that says "no obligation, cancel any time" needs to match what the contract actually says.

Card surcharges need advance notice in Kansas

If your invoice, estimate page or payment link adds a fee for paying by card, Kansas has a rule. K.S.A. 16a-2-403 says no person or retailer in a sales, service or lease transaction may impose a surcharge on a customer who elects to use a credit card unless the amount is disclosed through a clear and conspicuous notice at the point of entry or the point of sale, in advance of the transaction. The Revisor's page shows the section amended effective January 1, 2025.

For an online business, the "point of entry" is the first page where a customer starts the transaction, and the "point of sale" is where they pay. Putting the fee only on the final receipt does not meet that wording. Show the percentage on the quote, on the pay page and on the invoice. Card network rules add their own limits, which are not state law and are outside this page.

Sales tax decides what your invoice must say

The Department of Revenue's Publication KS-1525 gives a state rate of 6.5% plus local taxes. Labor to repair, service or maintain property is generally taxable, including on commercial buildings. Labor to install or apply materials at a residence, covering original construction, remodeling, repair or replacement, is exempt, and the residence includes yards, garages, sidewalks and driveways serving the home. The same publication says residential labor is still taxable when it installs retail items such as appliances and draperies or repairs personal property such as dishwashers and TVs. For lawn work, the department lists mowing, trimming, edging, aerating, dethatching, raking, cleanup, tree and stump removal and snow removal as not taxable. Applying pesticides, herbicides or fertilizer to residential lawns is taxable.

That split matters for online pricing. A lawn company that sells mowing and a fertilizer treatment on one quote needs two tax treatments on one invoice. A pressure washer or handyman that serves both homes and shops needs the same thing. Build the tax logic into the invoice template or the CRM once, rather than correcting invoices by hand. Our guide to sales tax on services explains how the rules differ by state.

What Kansas does not add for email and website data

CAN-SPAM governs commercial email in every state, and we found no separate Kansas statute on commercial email. We also found no Kansas law on website privacy notices in this research, and we did not confirm the current status of any pending privacy bill. Treat the federal rules as your floor and read the email marketing guide before you send a campaign.

What this means for your setup

• Website. Put the registration claim, tax treatment and card fee where the customer sees them before paying. Keep roofing registration status current. Build the site on a site you own, so these notices stay under your control.
• Business phone line. Recording is allowed with one party's consent, but announce it anyway. Keep the greeting and the recording notice in the system settings of your business phone system.
• AI receptionist. Inbound calls are not sales solicitations, so the No-Call Act does not govern them. If the assistant ever places outbound sales calls, it falls under the 18-month and no-call-list rules above. Our AI receptionist pages describe how calls are handled.
• Email. Federal rules apply. Keep a record of when each customer last bought, because Kansas ties the existing-customer exemption to a date.
