If you're shopping for a short-term rental purely as an investment — buy it, furnish it, run it through a management company, never set foot in it — Stonington isn't off the table the way a lot of coverage of this market claims. There's no town ordinance in Stonington today requiring an owner to live in the property, no permit process to clear, and no registration number to display. As things stand right now, the classic non-owner-occupied investment model that works twenty minutes up the road in Groton-side Mystic is not blocked by any Stonington town rule either.

That's not the same as saying Stonington is a safe, settled bet for a pure investment play, though — and that distinction is the actual story here, not a footnote to it. Stonington's government did draft a primary-residence requirement at one point — but town officials pulled that specific provision from the proposal in February 2023, on their own attorney's advice that it carried real legal risk, before the ordinance ever reached a vote. What actually went before voters in the March 13, 2023 referendum was a pared-down, registration-only version: annual registration with fines for non-compliance, nothing about where the owner lives. Voters rejected even that scaled-back version, 694 to 342. No replacement has been adopted since. So the town has now backed off a primary-residence rule once on its own legal team's advice, and then seen a much lighter registration-only ordinance rejected outright by referendum — two separate signals, both pointing away from near-term regulation, even as Connecticut has since made a future attempt legally easier to mount. Stonington's actual situation is a regulatory wildcard: genuinely open today, openly contested, and worth watching rather than assuming permanent either way.

For an investor evaluating the Mystic & Stonington corridor as a single opportunity, that distinction changes how you should underwrite a Stonington purchase — not by ruling it out, but by pricing in a real, non-zero chance the rules change under you.

What's Actually on Stonington's Books Today (Not Much)

A fair amount of circulating content — including, notably, Connecticut's own Office of Legislative Research, in its 2024 survey of municipal short-term rental regulation (Report 2024-R-0044) — describes Stonington as having an active ordinance requiring annual registration, a town-issued permit, listing disclosure of a registration number, and a primary-residence requirement enforced through an escalating penalty ladder. That description appears to be a documented error. It most likely traces back to a document still hosted on Stonington's own website, titled "str_ordinance_final.pdf" and dated January 13, 2023 — an earlier draft that did include a primary-residence requirement and an escalating penalty structure. That draft isn't what voters actually saw on the ballot, though: the town's own attorney flagged legal risk in the primary-residence provision, it was stripped out in a pared-down version released in February 2023, and that lighter, registration-only ordinance is what went to referendum and was rejected. OLR's description matches the superseded January draft, not the ordinance actually voted on — and neither version was ever adopted.

Two independent primary sources contradict OLR on this specific point. The Southeastern Connecticut Council of Governments' October 2023 report on statewide STR regulation lists Stonington's ordinance status as a flat "No," noting the "Town Ordinance defeated 3/23." And Stonington's own current "Special Acts and Local Ordinances" index — the town's official list of what's actually in force — has no short-term rental entry anywhere. We found no evidence of any Town Meeting vote, Board of Selectmen action, or other adoption mechanism between the March 2023 referendum and today that would have brought a revised ordinance into force. (A claim that sometimes circulates, referencing "amendments to the ordinance adopted at Town Meeting last year" in a February 2025 item, could not be verified in any primary source and should be treated as unsupported — a direct check of Stonington's actual 2025 Town Meeting record turned up parking, harbor management, and other unrelated items, nothing STR-specific.)

What is actually in force: Stonington's Planning and Zoning Commission decided back in 2017 not to regulate short-term rentals through the zoning code, and an old, general provision requiring stays of 30 consecutive days or longer technically remains on the books but isn't actively enforced. That's it. No permit. No registration. No primary-residence requirement. If you're relying on OLR 2024-R-0044 to tell you Stonington's rules, don't — it appears to get this specific town wrong.

Why "No Rule" Isn't the Same as "No Risk"

The standard short-term rental investment thesis is straightforward: buy a property in a strong vacation market, furnish it for guests, hand day-to-day operations to a management company or handle it remotely, and treat it purely as an income-producing asset you may rarely visit. Today, nothing in Stonington's town code stands between an investor and that model.

But the 2023 process tells you something real about the town's politics, and it's worth taking seriously rather than filing away as ancient history. Stonington's government did draft a primary-residence-based ordinance at one point, specifically to address the absentee-investment pattern that pure rental-only properties represent — then withdrew that provision itself, on legal advice, before it ever reached a vote. What voters actually rejected in March 2023 was the lighter, registration-only version that replaced it, and they rejected it by a real margin (694-342), not a squeaker. That's two data points working against near-term regulation, not one — but the underlying tension that produced both drafts hasn't gone anywhere. Public Act 24-143, effective October 1, 2024, has since given every Connecticut municipality clearer statutory authority to adopt STR licensing ordinances, removing a legal ambiguity that existed at the time of Stonington's first attempt. That makes a second attempt easier to mount procedurally than the first one was, even if it's not guaranteed to happen or to succeed if it does.

Twenty minutes away in Groton-side Mystic, the picture is more settled, if narrower: Groton's zoning framework, in force since May 2024, does impose a primary-residence condition, but only in residential zones — commercial and mixed-use zones, including downtown Mystic, allow a non-owner-occupied rental through site plan and special permit review. An investor buying into a Groton-zoned commercial or mixed-use parcel today is operating under a real, adopted, currently-tested rule. An investor buying into Stonington today is operating in the absence of a rule that a majority of the town's government has already tried once to put in place. Those are two different kinds of certainty, and it's worth being honest with yourself about which one you're actually buying into.

The Revenue Picture, Read Honestly

Market data on Stonington short-term rentals is noisy and platform-dependent. Estimates run from around AirROI $42,281 as of 2026-07-31 on the low end up to roughly AirROI $42,281 as of 2026-07-31 on at least one live data pull (AirROI), with most sources clustering in a AirROI $42,281 as of 2026-07-31 band — on balance still toward the lower end of the roughly AirROI Groton $46,361 / Stonington $42,281 as of 2026-07-31 blended range commonly cited for Mystic proper, though the spread is wide enough that a given Stonington listing could land closer to Mystic's numbers than the headline range suggests. It's tempting to attribute the gap to a regulatory restriction shrinking the eligible listing pool, the way it would in a town with an active primary-residence ordinance. But that's not what's happening here, since no such ordinance is currently in force. The more plausible explanation is Stonington's smaller, more residential inventory base and its greater distance from the Seaport tourism corridor that anchors Mystic's higher-revenue listings.

That reframes the investment case a little: Stonington's softer numbers aren't the price of a regulatory carve-out you're avoiding by buying there instead of somewhere more restricted — they're closer to Stonington's baseline market character, restriction or not. Which means the real question for an investor isn't "does Stonington's rule rule me out" (it currently doesn't), but "does Stonington's revenue ceiling clear my bar, and can I stomach the chance the rules change while I own the property."

Who Stonington Actually Works For Right Now

Given the genuine (if currently open) regulatory uncertainty, Stonington isn't a one-size answer. A few buyer profiles make more sense than others:

The buyer who can absorb a rule change without the deal falling apart. If a primary-residence requirement were reinstated on a future purchase-date basis (which is roughly how Stonington's earlier, since-withdrawn primary-residence draft was structured — it applied prospectively to buyers after adoption, with existing owners potentially grandfathered), an owner willing to occupy the property part-time, or pivot to a long-term rental if the STR model stopped working, has a much smaller downside than an owner whose entire financial plan depends on an uninterrupted absentee-rental income stream.

The owner-occupant who was always going to be fine either way. Someone who already lives in Stonington, or plans to split time there, isn't exposed to the regulatory wildcard at all — a future primary-residence rule wouldn't touch their plans regardless of which way the town goes. For that buyer, Stonington's current openness is a bonus, not the deciding factor.

The purely absentee investor who wants Mystic's certainty instead. If your plan truly depends on never occupying the property and you want a settled, tested regulatory environment rather than an open question, a Groton-side commercial or mixed-use parcel — where the non-owner-occupied path is a real, adopted rule rather than an absence of one — is the more conservative version of the same corridor bet.

None of these profiles should treat Stonington's current rules as a green light to ignore the town's history. Checking in on Stonington's zoning and Board of Selectmen agendas periodically, the way you'd track a zoning variance risk anywhere, is a reasonable ongoing diligence habit for anyone holding a Stonington property as a rental.

Positioning a Stonington Listing the Right Way

A Stonington listing doesn't need to hide behind a residency requirement that doesn't currently exist, but it also shouldn't pretend the town's regulatory history isn't real. That means leading with what actually differentiates Stonington — a walkable historic borough with 19th-century sea captains' houses, a working waterfront, and a lighthouse museum, positioned within a short drive of Foxwoods Resort Casino and Mohegan Sun, drawing a different kind of guest than the aquarium-and-drawbridge crowd on the Mystic side. Whole-home, non-owner-occupied listings can market themselves as such today; an owner-occupant host can lean into being present on-site as its own selling point, since plenty of travelers actively prefer that for the local recommendations and sense of security it implies. Either way, the content and SEO should build around the borough's walkability, harbor views, and position as a quieter alternative to Mystic proper — not around a compliance story that isn't currently accurate.

Frequently Asked Questions

Can I buy a property in Stonington purely as a short-term rental investment and never live there?

Under Stonington's current rules, yes - there is no adopted ordinance requiring primary residence. The town drafted one at an earlier stage but withdrew that specific provision on its own attorney's advice before it reached a vote; the lighter, registration-only ordinance that replaced it was then rejected by voters in March 2023, and nothing has replaced it since. That said, this could change, since the town has now tried to regulate short-term rentals twice, in two different forms.

Is Stonington's short-term rental ordinance actually in effect?

No. Despite some sources - including a Connecticut Office of Legislative Research report - describing an active ordinance with registration, permitting, and primary-residence requirements, no such ordinance is currently adopted. That description appears to stem from an earlier 2023 draft ordinance, later withdrawn and replaced before the actual vote, still being hosted on the town's website and mistaken for adopted law.

Why does Mystic proper, on the Groton side, seem more regulatorily settled than Stonington?

Because it is, in a narrow sense: Groton's zoning framework, in force since May 2024, has an adopted, tested rule - a primary-residence requirement in residential zones, and a defined non-owner-occupied path via site plan and special permit review in commercial and mixed-use zones, including downtown Mystic. Stonington currently has no adopted rule at all, which means more openness today but also more uncertainty about tomorrow.

What's actually on Stonington's books today regarding short-term rentals?

Not much. Stonington's Planning and Zoning Commission decided back in 2017 not to regulate short-term rentals through the zoning code, and an old, general provision requiring stays of 30 consecutive days or longer technically remains on the books but isn't actively enforced. The Southeastern Connecticut Council of Governments' October 2023 report on statewide STR regulation lists Stonington's status as a flat 'No,' noting the town ordinance was defeated 3/23, and the town's own current index of local ordinances has no short-term rental entry.

What's a realistic annual revenue range for a Stonington short-term rental?

Estimates cluster around $42,281, generally toward the lower end of Mystic proper's range, where nearby Groton reads closer to $46,361. That gap appears to reflect Stonington's smaller, more residential inventory and distance from the Seaport corridor rather than any current regulatory restriction.

Who does Stonington actually work for as a short-term rental market right now?

Someone comfortable with regulatory uncertainty in exchange for real flexibility today: an investor who wants to buy, furnish, and run a property purely as an income-producing asset, without a primary-residence requirement standing in the way, and who's willing to watch for a possible third regulatory attempt down the road.

Why isn't 'no rule' the same as 'no risk' in Stonington?

Because the town has already tried to regulate short-term rentals twice - once with a primary-residence draft withdrawn before a vote, once with a lighter registration-only version rejected by voters - and neither attempt suggests the town has settled on leaving the market unregulated permanently. An investor underwriting a purchase here should treat the current openness as a snapshot, not a guarantee.

Should I trust the Connecticut Office of Legislative Research description of Stonington's rules?

Treat it as outdated, not current. That OLR report describes registration, permitting, and primary-residence requirements as if they were adopted law, but that language traces back to the 2023 draft ordinance that was withdrawn and never took effect. Confirm current status directly against Stonington's own local ordinance index rather than relying on a secondary summary.
