Mystic and Stonington get marketed as a single destination — cobblestone charm, tall ships, a shared stretch of the Connecticut coast between New London and the Rhode Island line. For a homebuyer, that's close enough to true. For an investor deciding where to put capital into a short-term rental, it is not. Mystic Seaport sits on the Groton side of the Mystic River, and Groton's zoning code has, since May 2024, treated non-owner-occupied short-term rentals as an use you can apply for. Stonington's town government tried to build a comparable framework in 2022 and 2023 — permit, annual registration, and, in an early draft, a primary-residence requirement for future buyers that the town's own attorney later forced out on legal-risk grounds — and voters rejected the pared-down version that actually reached the ballot at referendum. That single fact, more than square footage or curb appeal, is what should decide which side of the river an investment-focused buyer looks at first.

Why the Demand Story Holds Up Independent of the Regulatory Question

Before getting into permits and ordinances, it's worth separating the demand case from the regulatory case, because both towns share the same demand engine and it's a genuinely strong one. Stonington is a different story, and it's worth getting the sequence right because a lot of secondary sources still describe the town's proposed 2023 ordinance as if it were adopted policy, and often get the sequence of drafts backwards too.

Mystic Seaport Museum, the Mystic Aquarium, downtown Mystic's restaurant and shopping corridor, and the drawbridge itself pull tourist traffic across all four seasons, not just a June-through-August window. Market data from AirDNA's MarketMinder shows roughly 413 active short-term rental listings in Mystic running 41.0% / 40.2% against AirROI as of 2026-07-31 annualized occupancy at an average daily rate AirROI $405 / $360 as of 2026-07-31 — an occupancy curve that's meaningfully flatter than a pure beach market living or dying on ten summer weekends. Fall foliage visitors, holiday-season Mystic Seaport lantern events, aquarium field trips, and off-season wedding parties all keep beds filled in months a Cape Cod or Jersey Shore property would sit empty.

The second demand layer is one a lot of out-of-state investors underweight: Foxwoods Resort Casino in Ledyard and Mohegan Sun in Uncasville sit roughly 15 to 25 minutes from Mystic by car, on opposite sides of the Thames River but easily combined into a single trip. Casino-driven lodging demand runs largely independent of tourist-season patterns — conventions, concerts, and gaming trips happen in February as readily as July — and multiple regional property managers explicitly market Mystic-area rentals to guests splitting a weekend between the two casinos and the Seaport. That's a genuinely distinct demand pool layered on top of the maritime-heritage tourist base, not just marketing language.

Then there's the drive market, which is unusually broad for a market this size. Mystic and Stonington sit within striking distance of New York City (roughly three hours), Hartford (about an hour), Providence (45 minutes or less), and Boston (a shade under two hours). Few Northeast coastal markets can credibly pull short weekend traffic from four separate metros at once.

The Regulatory Fork: Groton Has a Permit Process. Stonington Doesn't — Yet Its Voters Already Said No to One.

This is the part that actually separates the two towns for an investor, and it's more nuanced than "one town allows it and one doesn't.". The town spent more than a year — starting with community conversations in mid-2022 — drafting an ordinance that would have required annual registration through a town-designated platform, an issued permit, a 60-minute response requirement for owners contacted by police or fire officials, and, in its January 13, 2023 draft, a primary-residence requirement that would have applied to anyone purchasing a residential home in Stonington after the ordinance's passage.

Groton — the municipality that contains most of downtown Mystic on the river's east bank — adopted zoning text amendments for short-term rentals that the Planning and Zoning Commission approved on April 9, 2024, effective May 15, 2024. The regulations ban short-term rentals outright in single-unit residential zones, heavy industrial areas, working waterfront, and open-space/green zones. In residential zones with one- and two-unit dwellings, rural residential zones, and multi-unit residential zones, short-term rentals are conditionally allowed with site-plan and special-permit approval — but only if the owner or a long-term lessee maintains their primary residence on the property. In neighborhood commercial, regional commercial, and mixed-use industrial zones, and in the mixed-use downtown districts of Mystic, downtown Groton, and Poquonnock Bridge, short-term rentals can also be approved through site-plan review (with a special permit and public hearing required in the downtown mixed-use areas) — without the same owner-occupancy condition that applies to residential zones. Every approved rental owes off-street parking for every bedroom, must clear a nuisance standard for neighbors, and must comply with lighting, building, fire, and electrical codes. Existing short-term rentals already operating were grandfathered in. Groton has not layered a separate town-wide licensing or registration system on top of this — the permit attaches to the property itself, not to an operator.

Practically, that means a purely investment-minded buyer who wants to hold a non-owner-occupied rental has a real, if narrower, lane in Groton: commercial and downtown mixed-use parcels, approved through site plan (and in the downtown districts, a special permit and public hearing), without being forced into owner-occupancy. It is not a rubber stamp, and it is not available on every lot — but it is a defined, currently operating process with an 18-month-plus track record as of this writing.

Stonington is a different story, and it's worth getting the sequence right because a lot of secondary sources still describe the town's proposed 2023 ordinance as if it were adopted policy, and often get the sequence of drafts backwards too. It was not adopted. The town spent more than a year — starting with community conversations in mid-2022 — drafting an ordinance that would have required annual registration through a town-designated platform, an issued permit, a 60-minute response requirement for owners contacted by police or fire officials, and, in its January 13, 2023 draft, a primary-residence requirement that would have applied to anyone purchasing a residential home in Stonington after the ordinance's passage. In February 2023, town officials pulled that primary-residence provision out of the ordinance — on the town attorney's advice that it carried real legal risk — before it ever reached voters. The version the Board of Selectmen actually sent to referendum was a pared-down, registration-only ordinance (with escalating penalties, starting around a $250 fine and a compliance warning, for non-compliance, but no residency mandate), and on March 13, 2023, Stonington voters rejected that version by a margin of 694 to 342.

That rejection matters more than it first appears — and so does the withdrawal that preceded it. Between the two, Stonington's government backed off a primary-residence rule once, on its own legal team's advice, and then saw a much lighter registration-only ordinance rejected outright by referendum. The net effect is that the town was left without any adopted permit or registration system at all. The town's Planning and Zoning Commission had already decided back in 2017 that it would not regulate short-term rentals through the zoning code, and an older general provision requiring stays of 30 days or longer technically remains on the books but isn't actively enforced. The net effect for 2026: Stonington has no clean, currently operating pathway to legally establish a new short-term rental the way Groton does. A pure investment play — buy a property, never live in it, run it as a rental — has no ordinance to comply with because there's no ordinance in force, but also no zoning-approved use category granting it certainty, which is a materially different (and arguably riskier) position than Groton's defined-but-conditional permit process. An owner who intends to actually live in the home part-time and rent it out the rest of the year sidesteps the entire debate that sank both the residency-based draft and the registration-only ordinance that replaced it, since owner-occupancy was the dividing line the town's own drafters used to distinguish acceptable rentals from the absentee-investor pattern residents organized against.

The state legislature, for its part, has twice tried to settle this at a higher level and failed both times. House Bill 7238, introduced in the 2025 session, would have created a state short-term rental registry, authorized an optional municipal supplemental tax, and required disaggregated tax reporting on rental filings; it advanced through the Finance, Revenue and Bonding Committee in April 2025 but died without reaching a final vote. House Bill 5536, introduced in the 2026 session by Rep. Aundré Bumgardner, proposed a similar statewide registry — its initial municipal tax provision (up to 2.5%) was stripped after pushback from hosts — and it, too, did not pass before the 2026 General Assembly session adjourned in May. Two consecutive sessions, two dead bills. For now, and likely for the foreseeable near-term, short-term rental regulation in Connecticut stays a town-by-town patchwork, which is exactly why the Groton/Stonington distinction matters as much as it does.

The Honest Revenue Picture

Regulatory access is only half the investment case; the numbers need to support it too, and here the two submarkets diverge less sharply than their zoning status might suggest. Stonington-specific data (184 tracked listings) is genuinely more variable across sources than Mystic's, and it's worth being honest that the sources don't agree on direction, let alone magnitude: one AirDNA-based estimate shows AirROI $42,281 as of 2026-07-31 in average annual revenue at 41.9% occupancy and a $361 ADR — which, taken at face value, is actually higher than the roughly $39,700 AirDNA-based figure cited above for Mystic, not lower — while another Stonington pull puts occupancy closer to 47% with a higher $433 ADR but only around AirROI $42,281.

Mystic proper — spanning the Groton and Stonington sides of the river together in most market data — blends to roughly AirROI Groton $46,361 / Stonington $42,281 as of 2026-07-31 in annual revenue per listing, depending on the data source and property mix. AirDNA's MarketMinder puts the market-wide average closer to the low end of that band, AirROI Groton $46,361 as of 2026-07-31 a year across 413 tracked listings, with 50% annualized occupancy and an average daily rate AirROI $405 / $360 as of 2026-07-31.

Stonington-specific data (184 tracked listings) is genuinely more variable across sources than Mystic's, and it's worth being honest that the sources don't agree on direction, let alone magnitude: one AirDNA-based estimate shows AirROI $42,281 as of 2026-07-31 in average annual revenue at 41.9% occupancy and a $361 ADR — which, taken at face value, is actually higher than the roughly $39,700 AirDNA-based figure cited above for Mystic, not lower — while another Stonington pull puts occupancy closer to 47% with a higher $433 ADR but only around AirROI $42,281 as of 2026-07-31 in annual revenue, well below Mystic's range. That disagreement is itself the honest takeaway: Stonington revenue data swings from meaningfully above Mystic's to meaningfully below it depending on which source you pull, and this cluster's broader thesis that Stonington trends toward the lower end of the range is a directional read across most sources, not a figure every individual pull confirms. Treat any single Stonington number — including both of the ones above — as a start-here estimate rather than a settled comp, and pull current, property-specific data before underwriting a deal. The lower end of that spread sits close to — but not clearly below — the threshold most operators in this cluster need to clear for a short-term rental to outperform a long-term lease on the same property. It's a market that can work financially; it's not a market that reliably underperforms Groton-side Mystic on revenue alone, which reinforces that the real decision point here is regulatory access, not raw yield.

Average daily rate across both submarkets, pulled together, lands somewhere in the AirROI $405 / $360 as of 2026-07-31 range depending on the month, property size, and data source queried — directionally useful for underwriting a deal, but not precise enough to hang a pro forma on without pulling comps for the specific property type and bedroom count under consideration.

Which Submarket Actually Fits Which Buyer

Reframed around eligibility rather than character, the choice looks like this: an investor who wants a rental-only play, with no intention of ever living in the property, should be looking at Groton-side Mystic — specifically parcels in the commercial and downtown mixed-use zones where the May 2024 zoning framework doesn't impose owner-occupancy, subject to site-plan and (downtown) special-permit approval. A buyer who wants to live in the home part of the year and rent it the rest of the time — the classic second-home-with-income-offset model — is Stonington's actual addressable buyer right now, not because the town has blessed that arrangement with a formal ordinance, but because owner-occupancy is the one profile that doesn't run headlong into the same absentee-investor objections that sank both the withdrawn residency-based draft and the registration-only ordinance that replaced it — objections that would likely resurface if the town tries again.

Every operator in both towns, regardless of which side of the river they land on, owes the same state obligation: Connecticut's Department of Revenue Services collects a 15% room occupancy tax on short-term rentals (11% for qualifying bed-and-breakfast establishments) for the first 30 days of any stay. Airbnb and Vrbo generally collect and remit this automatically for bookings made through their platforms, but hosts taking direct bookings, or bookings through channels that don't collect the tax, are responsible for registering with DRS and remitting it themselves.

Frequently Asked Questions

Is Stonington's primary-residence rule for short-term rentals actually in effect right now?

A January 2023 draft ordinance did include a primary-residence requirement for anyone buying a home in Stonington after its passage — along with registration, a permit, and escalating penalties — but town officials stripped that provision in February 2023 on the town attorney's advice about legal risk. The registration-only version that actually reached the ballot was rejected by Stonington voters in a March 2023 referendum, 694 to 342. No replacement ordinance has been adopted since, leaving the town without a formal short-term rental licensing system.

If Stonington doesn't have an adopted rental ordinance, can I just operate a short-term rental there freely?

Stonington's Planning and Zoning Commission decided in 2017 not to regulate short-term rentals through the zoning code, and an older general 30-day minimum-stay provision technically remains on the books, even though it isn't actively enforced. That's a regulatory gray zone, not a green light — it lacks the defined permit pathway Groton has. The town's Planning and Zoning Commission had already decided back in 2017 that it would not regulate short-term rentals through the zoning code, and an older general provision requiring stays of 30 days or longer technically remains on the books but isn't actively enforced.

Can I buy a property in Groton purely as a rental investment, with no plan to live there?

In residential zones, no — Groton's May 2024 zoning framework requires the owner or a long-term lessee to maintain their primary residence on-site for short-term rentals in those zones. In neighborhood commercial, regional commercial, mixed-use industrial, and the mixed-use downtown districts of Mystic, downtown Groton, and Poquonnock Bridge, a non-owner-occupied rental can be approved through site-plan review (plus a special permit and public hearing in the downtown areas).

How does casino proximity actually affect Mystic-area rental demand?

Foxwoods Resort Casino (Ledyard) and Mohegan Sun (Uncasville) sit roughly 15 to 25 minutes from Mystic by car and are commonly combined into a single trip. That traffic runs on gaming and event schedules rather than tourist-season patterns, giving Mystic-area rentals a demand layer that doesn't fully collapse in the off-season the way a purely beach-driven market would.

What's a realistic annual revenue estimate for a Mystic-area rental?

Market data puts Mystic proper in a roughly AirROI Groton $46,361 / Stonington $42,281 as of 2026-07-31 annual revenue range per listing, with AirDNA-based estimates for the broader market closer to $40,000 at 41.0% / 40.2% against AirROI as of 2026-07-31 annualized occupancy. Stonington-specific data runs somewhat lower and more variable, roughly AirROI $42,281 as of 2026-07-31 depending on the source, which is close to — though not clearly below — typical short-term rental viability thresholds.

Is there a statewide Connecticut short-term rental registry I need to worry about?

Two consecutive legislative sessions have tried and failed to pass one: House Bill 7238 in 2025 died in committee after an April 2025 Finance Committee vote, and House Bill 5536 in 2026 — which would have created a similar statewide registry — also did not pass before that session adjourned. Regulation remains town-by-town for now.

Do I owe Connecticut lodging tax even if Airbnb collects it for me?

Connecticut's Department of Revenue Services imposes a 15% room occupancy tax on short-term rentals (11% for qualifying bed-and-breakfasts) on the first 30 days of any stay. Airbnb and Vrbo typically collect and remit this automatically on bookings made through their platforms, but if you take direct bookings or use a channel that doesn't collect the tax, you're responsible for registering with DRS and remitting it yourself.

How far does the Mystic/Stonington market's drive market actually reach?

Roughly three hours to New York City, about an hour to Hartford, 45 minutes or less to Providence, and just under two hours to Boston — a broader multi-metro pull than most coastal Connecticut or Rhode Island markets of comparable size can claim. Mystic and Stonington sit within striking distance of New York City (roughly three hours), Hartford (about an hour), Providence (45 minutes or less), and Boston (a shade under two hours).
