The Statute
What the law actually says
Connecticut permits home cultivation. Neither statute requires it happen indoors.
Since July 2023, any adult in Connecticut may cultivate a small number of cannabis plants at home. Registered medical patients have been permitted to do so since October 2021. Both allowances are set by statute, and both statutes are short enough to read in full.
Conn. Gen. Stat. § 21a-278c — complete text
Notwithstanding the provisions of section 21a-278b, any consumer may cultivate up to three mature cannabis plants and three immature cannabis plants in the consumer's primary residence, provided such plants are secure from access by any individual other than the consumer and no more than twelve cannabis plants may be grown at any given time per household.
June Sp. Sess. P.A. 21-1, S. 162. Effective July 1, 2023. That is the entire section.

There is no requirement that cultivation occur indoors. There is no requirement that plants not be visible. The words do not appear.
Conn. Gen. Stat. § 21a-408d(b) — complete text
Any qualifying patient who is eighteen years of age or older may cultivate up to three mature cannabis plants and three immature cannabis plants in the patient's primary residence at any given time, provided such plants are secure from access by any individual other than the patient or patient's caregiver and no more than twelve cannabis plants may be grown per household.
The medical provision reads the same way, and contains the same silence.

Where the rule comes from
The Department of Consumer Protection's public guidance states that “Plants must be grown indoors and must not be visible from the street.” The same page directs readers to review the home grow rules “on the last page of the Department's policies and procedures.”
Those policies are issued under a provision of the Regulation of Adult-Use Cannabis Act that is worth reading closely.
Conn. Gen. Stat. § 21a-421j(b)
Notwithstanding the requirements of sections 4-168 to 4-172, inclusive, in order to effectuate the purposes of RERACA and protect public health and safety, prior to adopting such regulations the commissioner shall issue policies and procedures to implement the provisions of RERACA that shall have the force and effect of law… at least fifteen days prior to the effective date of any policy or procedure.
The commissioner may issue binding policy in fifteen days.
Sections 4-168 through 4-172 of the general statutes are Connecticut's Uniform Administrative Procedure Act. They are the process by which agency rules become binding — and the statute above sets all of them aside.
What that provision sets aside
| Requirement | Chapter 54 regulation | Agency policy and procedure |
|---|---|---|
| Public comment period | At least 30 days | None required |
| Attorney General legal review (§ 4-169) | Required | Not required |
| Small business impact analysis (§ 4-168a) | Required | Not required |
| Fiscal note | Required | Not required |
| Legislative Regulation Review Committee approval (§ 4-170) | Required | Bypassed |
| Notice before taking effect | 30+ days plus committee review | 15 days |
| Force of law | Yes | Yes |
A rule that determines whether a disabled veteran can afford to grow their own medicine was made without a public comment period, without a fiscal note, without a small business analysis, and without a vote by the General Assembly or its Regulation Review Committee.
That is the decision this project asks the legislature to take back.
What we can confirm, and what we are still checking
The indoor-only requirement is real and is not in dispute — the Department states it plainly in its public guidance, quoted above. What we are verifying is which legal instrument carries it: a formally adopted regulation, which would have gone through Attorney General review and Legislative Regulation Review Committee approval, or agency policies and procedures issued under § 21a-421j, which bypass both. The Department adopted final cannabis regulations in January 2025. That distinction does not change the rule. It changes whether the legislature ever approved it. We have asked the Office of Legislative Research and will publish the answer here either way, including if it weakens our argument.
