Does a cleaning business need a license in Connecticut?
Connecticut licenses no cleaning business trade, but a statewide credential may still reach you.
Whether the Homemaker-Companion Agency registration reaches an ordinary residential cleaning company has not been resolved by the department or a court. Operating without it, if it does reach you, is a misdemeanor.
Connecticut licenses no cleaning or janitorial trade, and janitorial, window cleaning and maintenance services are instead taxable under General Statutes section 12-407(a)(37), collected by the Department of Revenue Services. Separately, section 20-671 requires any organization employing one or more persons to provide homemaker services to hold a Homemaker-Companion Agency registration, and section 20-670(8) defines those services to include household cleaning in a person's home, with the chapter's only exemption being for agencies already licensed by the Department of Public Health. Whether that reaches an ordinary residential cleaning company has not been resolved publicly by the department or a court: none of the 1,236 active registrants is a cleaning company, while operating without the certificate is a misdemeanor under section 20-677(b)(5) and (c), so a Connecticut cleaning business with employees can ask the department to confirm its position in writing before it opens.
Section 20-671 puts the duty on the organization, defined at 20-670(7)(A) as any public or private organization employing one or more persons engaged in the business of providing homemaker services.
This records what Connecticut publishes, not a determination about your business. Scope, thresholds and local requirements are set by the issuing body, so confirm with them before you bid or file.

What the LLC has to do first
Almost no state licenses house cleaning as a trade. The registrations that do apply are the entity filing, sales tax where cleaning is taxable, and any local business license.
The entity filing is separate from anything the license requires. In Connecticut it is made with the Connecticut Secretary of State. File directly with the state here. The order matters wherever the license is issued to the company rather than to a person: the entity has to exist before an application can name it.
Forming an LLC as a cleaning business in Connecticut covers the filing itself, step by step.
Insurance Connecticut cleaning businesses are asked to show
Residential clients hand over a key and commercial contracts require a certificate before the first shift, so general liability is bought at the point of winning work rather than at the point of registering.
We do not publish Connecticut premium figures for this trade, so nothing here is a quote. Our business insurance guide for cleaning businesses covers what each policy does and does not pay for.
This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state licensing board publishes for this trade, with the sources this page cites. It cannot tell you whether your own work needs a licence: that turns on the scope of the job, the value of the contract, and the city or county you work in, which commonly adds its own registration on top of the state's. Confirm your own position with the board named on this page and with your local building or business licensing office before you bid or start work.
