Groton, Connecticut Short-Term Rental Regulations: A 2026 Guide For Airbnb Hosts

Do you own a place in Groton, Connecticut and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that nobody in Groton has banned short-term rentals across the board, and Connecticut doesn't ask you to hold a state licence for one either. The complication is that Groton isn't a single jurisdiction. Four separate zoning authorities share the same town line here in New London County, and the one that draws the map under your deed decides whether you've got a business or a violation.

The Town of Groton's Planning and Zoning Commission has regulated short-term rentals since May 15, 2024, and it revised that same section again effective April 15, 2026. In most of the town's residential zones you'll need a special permit, a public hearing and your own primary residence on the lot, while in the single-unit residential zones the answer is a flat no. Noank went further still, prohibiting short-term rentals in every one of its zoning districts on December 1, 2024. The City of Groton and Groton Long Point each run their own regulations on top of all that, and neither one reads like the town's.

So let's walk through what it actually takes to do this properly in 2026: which zones allow what, what the commission wants to see on paper, the tax Connecticut takes off every booking, how enforcement works when there's no registry to enforce against, and who to call in each of the four jurisdictions. Every figure below comes from the town's, the district's or the state's own documents, checked in July 2026, and where I couldn't confirm something I've said so rather than filled the gap. Before any of it, though, do run the property through BNBCalc, because an owner-occupied spare bedroom is a very different investment from a whole waterfront house.

What are Short-Term Rental (Airbnb, VRBO) Regulations in Groton, Connecticut?

Which of those two you're allowed to run comes down to a single section of one rulebook, so the first job is working out whose rulebook covers you. Connecticut's zoning statute sets the split up, since Section 8-1(b) of the General Statutes gives a town's zoning commission jurisdiction over the part of the town lying outside any city or borough contained in it. Groton has a city inside it, plus two more districts that have held zoning powers for decades, which is how one place name ends up with four rulebooks.

The Town of Groton's version covers most of the housing stock. Its zoning regulations define a short term rental, at Section 2.1 and with effect from May 15, 2024, as the use of a furnished legal dwelling unit, in whole or in part, providing transient lodging to the general public, for compensation, for a period of 30 days or less. Section 5.1-7.C then sets the conditions, while Table 4.1 decides which districts get to use it at all, and since the April 15, 2026 revision the picture looks like this:

• Special permit, site plan and conditions in R-7 and R-12 (Residential), the RU rural residential districts, RM (Residential Multi-Unit), and the three mixed-use districts, MDD (Mystic Downtown District), MTC (Mixed-Use Town Center) and MVC (Mixed-Use Village Center).
• Conditions and a site plan, without a special permit, in CN (Commercial, Neighborhood), CR (Commercial, Regional), IM (Industrial, Mixed-Use) and R-MI, the tiny Residential Mouse Island district added in 2025.
• Not permitted at all in RS-12 and RS-20 (Residential, Single Unit), WW (Working Waterfront), IG (Industrial, General), and the two green districts, GR and GC.

That RS line is the one that catches people, since a lot of Groton's detached single-family housing sits in exactly those districts. No permit or fee moves it. Assuming your parcel does land in a district that allows the use, Section 5.1-7.C still attaches conditions that shape what you can run:

• One short term rental per lot in the R, R-MI and RU districts, and no more than one per lot in RM districts with existing single- and two-unit dwellings.
• The rental lives in the principal dwelling unit or in one accessory building, and not both.
• You have to live there. In an R, RU or RM district, the owner or lessee of the lot must have their primary residence in one unit of a two-unit dwelling, in the principal dwelling unit, or in a legally permitted accessory dwelling unit.
• One off-street parking space for every short term rental bedroom, all of it on the same lot as the rental.
• No exterior evidence of the activity in residential and mixed-use districts beyond a sign permitted under Section 8.4 and the required parking.

On top of those, the regulations import the environmental performance standards of Section 7.4 for noise and nuisance, and they ask the applicant to show through setbacks, buffering, topography "or other means" that the rental won't be a nuisance to abutting residential neighbours. Lighting standards apply to any short term rental that isn't physically connected to the principal dwelling, and the building itself has to comply with the zoning, building, fire, electrical and plumbing codes. Temporary events hosted by short term rental occupants are barred in the R districts and on RU sites under two acres, so don't plan a wedding venue around the spare cottage.

Now the other three jurisdictions, because this is where a lot of Groton listings actually sit. Noank is the hardest line in the town: Section 2.31 of the Noank Fire District's zoning regulations, added December 1, 2024, says the rental of a dwelling unit for thirty consecutive days or less "is prohibited in all zoning districts of the Noank Fire District," and it bans renting to more than one family during the same period for good measure. The commission's own notice to property holders frames the amendment as codifying a long-standing position and warns that violators may face fines and injunctions.

Groton Long Point and the City of Groton are quieter, though quiet isn't the same as permissive. The Groton Long Point Association's zoning regulations, revised in August 2026, permit one-family dwellings in the Single Family Residence District and say nothing about short-term rentals, transient lodging or minimum stay lengths anywhere in the document, and its ordinances don't cover them either.

The City of Groton's zoning regulations, adopted January 22, 2025 and effective February 6, 2025, mention short-term rentals exactly once, in the use table for the GC and GCR business zones, and even there the entry is marked as still to be determined. Neither set gives you a clean yes, so make sure you call the relevant office before you list rather than after.

Starting a Short-Term Rental Business in Groton

Unfortunately for a good number of people reading this, that primary-residence condition removes the plan they walked in with. Buying a house in one of the town's residential zones, furnishing it and renting it whole at nightly rates isn't available in Groton, because Section 5.1-7.C.3 requires the owner or lessee to live on the lot in an R, RU or RM district.

No corporate structure gets around that, since the condition attaches to the property and to whoever occupies it.

What the rules do leave open is worth knowing, mind you. The primary-residence condition is written for the R, RU and RM districts only, so it doesn't reach the commercial and mixed-use districts. A short term rental in CN, CR or IM needs conditions and a site plan and no resident owner, and one in MDD, MTC or MVC needs a special permit but again no resident owner. That matters more than it sounds, because MDD is the Mystic Downtown District, the visitor-facing core that most of Groton's nightly-rate demand actually points at.

Then there's the question everyone asks, which is what happens to the listings that were already running. Existing uses that were lawful before the regulations changed don't vanish, since Sections 9.7-3 and 9.7-4 let a lawful use of land or of a structure continue as a non-conforming use as long as it stays otherwise lawful.

Keep in mind how narrow that protection is, though. A non-conforming use can't be enlarged beyond the area it occupied on the effective date, can't be moved elsewhere on the lot, can't be resumed once a permitted use supersedes it, and dies if the owner abandons it by an overt act. Buying a house that "has been an Airbnb for years" hands you no paperwork proving any of that, so treat a seller's claim as something to verify with the town rather than something to price into your offer.

If Groton's residential zones close the door on your model, the rest of New London County is worth a look before you give up on the region, and our Norwich guide covers the nearest larger market with its own approach. For the wider state picture, including the towns that never adopted anything at all, the Connecticut statewide guide is the better starting point.

Short-Term Rental Licensing Requirement in Groton

Groton diverges from most towns that regulate at all, then, because there's no licence, no registration and no annual renewal, which sounds like relief right up until you see what stands in its place. The town chose zoning rather than an ordinance, and that choice has consequences the town spelled out itself on the Greater Groton project page. A zoning approval attaches to the property rather than to the operator, gets enforced by the zoning enforcement officer rather than the police, and applies only to new uses.

The Town Council has held off on a registration ordinance, and its municipal code shows it. Going through the Town of Groton code on eCode360, which carries legislation through August 5, 2025, there's no short-term rental chapter anywhere in it, including in Chapter 10 on licences and business regulations. So there's nothing to renew. What you file instead is a land-use application, not a permit application in the usual sense.

That application runs one of two ways, depending on your district. Under Section 9.5-1.A, the Planning and Zoning Commission has to review and approve a site plan before a zoning permit can issue for any new use. The Director of Planning and Development Services can grant an administrative site plan instead, under Section 9.5-1.B, where the use is minor and doesn't significantly change intensity, traffic circulation or public safety. In the six districts flagged for a special permit, you also get a public hearing, since Section 9.4-5.B requires the commission to hold one on every special permit application.

Timing is where a special permit stops being a formality. Under Section 9.1-10, a public hearing has to commence within 65 days of official receipt of the application, close within 35 days of commencing, and be decided within 65 days of the close, and the applicant can consent to extensions totalling up to another 65 days. Add those up and a contested application can legitimately run most of a season, whereas a site-plan-only approval has to be decided within 65 days of receipt. So if you're buying with a summer launch in mind, count backwards generously.

Three more features of a special permit are worth having in front of you before you apply. Under Section 9.4-5.E, any condition the commission attaches binds the property for as long as the use operates, and it survives a change of ownership. Section 9.4-9 then lets the commission impose time limits or require periodic renewal without a further public hearing, and an expired special permit is null and void.

Then there's Section 9.4-5.F, which says the commission shouldn't approve a special permit for a property that already carries a zoning violation unless the application cures it. That one's a real problem for anyone who's been quietly hosting since 2024 and now wants to regularise.

As for cost, Section 9.1-2.D says applications must arrive with "the appropriate fee(s) as established by the Town of Groton," and I couldn't find a published land-use fee schedule anywhere on the town's website in July 2026, so I'm not going to quote you a number I haven't read. Applications and payment run through the town's Citizen Self Service portal, which adds a 3.95% card convenience fee with a $2.50 minimum, or $1.95 for ACH. Do ask Planning and Development Services for the current schedule before you budget.

Required Documents for Groton Short-Term Rentals

Since nobody will quote you a fee until you ask, the sensible move is still to arrive with a complete package the first time. Applications go on forms obtained from the Office of Planning and Development Services under Section 9.1-2.C, and Section 9.1-2.F requires both the applicant and the property owner to sign, which matters when a long-term lessee is the one applying. Where the work also touches a regulated wetland, Section 9.1-2.B says the Inland Wetlands Agency application has to go in before or alongside the commission's.

Beyond the form itself, the material the town will be reading comes down to a handful of exhibits:

• A plot plan based on a survey by a Connecticut-registered land surveyor, under Section 9.2-2.A, showing lot dimensions, buildings, setbacks, driveways, curb cuts and impervious cover. The Zoning Official can reduce that requirement where the detail isn't needed. Do ask first.
• A parking plan demonstrating one off-street space per short term rental bedroom, all located on the rental's own lot.
• A nuisance demonstration, showing through setbacks, buffering, topography or other means that the rental won't be a nuisance to abutting residential neighbours.
• Evidence of primary residence where the property sits in an R, RU or RM district.
• Code compliance across the zoning, building, fire, electrical and plumbing codes, which in an older Groton house is the line item most likely to produce a surprise.

One 2026 change deserves separate attention if your property is anywhere near the water, and in Groton that's a lot of properties. The April 15, 2026 amendments revised Section 9.5-5.B to eliminate the exemption for single unit dwellings from coastal site plan review. Anything inside the coastal boundary is already subject to Section 9.5-5, so single-family owners who previously sailed past that step now don't.

Be aware that this one wasn't announced as a short-term rental change at all, even though it landed in the same amendment cycle that opened the R-MI district to short term rentals. Owners on Mouse Island have their own extra condition too, since the septic holding tank has to be pumped annually with evidence filed with the planning office each April, along with proof of a tank alarm system.

Groton Short-Term Rental Taxes

Assuming you get through all that and are able to start hosting, there's still tax to deal with, though Connecticut keeps this part refreshingly simple compared with the permitting. One tax, one collector. No Groton authority layers anything on top of it.

Charge	Rate	Collected by
Room occupancy tax, short-term home rentals	15%	CT Dept of Revenue Services, or the platform
Room occupancy tax, bed and breakfast establishments	11%	CT Dept of Revenue Services, or the platform
Town of Groton lodging tax	none	not applicable
New London County lodging tax	none	not applicable

The rates come straight from the Department of Revenue Services' room occupancy tax page, which puts hotels, motels, lodging houses and short-term home rentals at 15% and bed and breakfast establishments at 11%, and the underlying authority is Conn. Gen. Stat. § 12-408(1)(B). The tax stops applying on the 31st consecutive day of occupancy by the same person, so a long winter booking falls out of it entirely.

Whether you ever touch that money yourself depends on how you take bookings. Under Section 12-408h, a qualifying short-term rental facilitator becomes the retailer of record and has to collect and remit the room occupancy tax on every booking it handles, which is why Connecticut sits on Airbnb's own list of jurisdictions where it collects and remits. On those bookings Airbnb takes 15% of the listing price including cleaning fees for the first 30 nights, and nothing at all where the reservation runs past 90 nights.

Take a direct booking, though, or use a channel that doesn't collect, and the obligation lands back on you. Registering for room occupancy tax costs $100 with DRS, waived if you already hold a sales and use tax permit, and Form OP-210 is then filed and paid electronically through myconneCT by the last day of the month following each period.

One thing not to plan around: there's still no municipal add-on in Connecticut. House Bill 5536 would've allowed towns an optional supplemental tax of up to 2.75% of rent alongside a state registry, yet it died without a floor vote when the 2026 session adjourned. If you're comparing Groton against the rest of the region on the numbers rather than the rules, the New London market is where the comparable performance data for this stretch of the shoreline lives.

Connecticut Wide Short-Term Rental Rules

That failed bill is a useful way into the state layer, because it shows what Connecticut has chosen not to do. There's no statewide short-term rental licence, no state registry and no preemption stopping a town from writing whatever rules it likes. House Bill 5536 would've required operators to register each property annually with DRS for $100, and although it cleared the Finance, Revenue and Bonding Committee 36 to 18 on March 30, 2026 and was tabled for the House calendar that April, it went nowhere before adjournment on May 6, 2026. Watch for it again in 2027, but don't describe a state registry as current law.

What the state did do was hand towns explicit authority. Under Section 7-148qq, enacted as Public Act 24-143 and effective October 1, 2024, any municipality can adopt an ordinance requiring the licensure of short-term rental properties and regulating how they operate, by vote of its legislative body. Before that, whether towns could regulate short-term rentals at all was genuinely unsettled, which is why the legislature's own researchers found only 12 towns with short-term rental ordinances or zoning rules as of February 2024. Groton chose zoning instead of a licensing ordinance, and that second route is still open to the Town Council later.

The other piece of state law reshaped everything, and it came from a courtroom rather than the Capitol. The Connecticut Supreme Court's decision in Wihbey v. Zoning Board of Appeals of the Pine Orchard Association, officially released July 29, 2024, held that language permitting the use of a property as a single-family dwelling was ambiguous and that short-term renting that dwelling was a permissible use under those regulations. Two justices dissented, mind you, so it wasn't a comfortable margin. Read practically, silence now favours the host, since a town that wants to stop short-term rentals has to say so in writing.

Noank's own notice to property holders says its amendments "were required to conform to a 2024 decision of the Connecticut Supreme Court," which is exactly what that looks like on the ground. The case itself came out of Branford, so our Branford guide and the wider New Haven County guide cover the shoreline towns where the ruling has been felt most.

Does Groton Strictly Enforce STR Rules?

That court decision explains a lot about how enforcement here feels, because both of the Groton-area jurisdictions that acted did so to get their language in order first. Enforcement itself is complaint-driven, and there's no registry, no permit number in listings and no platform-side verification, so nothing automatically matches an Airbnb listing to an approval. A neighbour is the usual trigger.

Once a complaint lands, though, the machinery that follows is still ordinary Connecticut zoning enforcement. Section 9.2-1.A puts enforcement with the Planning and Zoning Commission acting through the Zoning Official, who can inspect any premises and order the remedying of a violation in writing, while Section 9.2-1.D lets any official with jurisdiction bring an action to restrain, correct or abate the violation or prevent occupancy.

Section 9.2-1.C then says offenders "will be fined in accordance with the General Statutes of the State of Connecticut," and Section 8-12 of those statutes sets the figure at not less than $10 and not more than $100 for each day the violation continues. Watch out for the wilful tier, though, since that runs from $100 to $250 per day and carries up to ten days' imprisonment for each day of violation, capped at thirty days.

Daily accrual is the part people underestimate. A hundred dollars sounds survivable until you notice it isn't a one-time fine. It accrues. A season of weekend bookings can leave a much larger number sitting behind you than in front of you, and Noank's own notice reminds property holders that violators may be subject to "fines and injunctions," which reads as a district that has already thought about the second half of that sentence.

How hard the town pushes in practice is harder to pin down, and I'd rather say so than invent a number. Going through the town's pending land use applications in July 2026, I found no short-term rental site plan or special permit applications listed at all, which suggests the approval route isn't well travelled yet. That cuts two ways. It may mean few people are asking, or it may mean the town isn't forcing the question.

Either way, a permit granted with conditions binds the property indefinitely, and an unresolved violation blocks a later special permit under Section 9.4-5.F. So the cheap-looking path of hosting first and asking later gets expensive the moment you want anything else from the commission.

How to Start a Short-Term Rental Business in Groton

Given how much rests on which map you're on, the order below still matters more than it looks, since the first two steps often end the exercise before you've spent anything.

1. Establish which jurisdiction you're in. Town of Groton, City of Groton, Noank Fire District or Groton Long Point. In Noank, short-term rentals are prohibited in every district and step two doesn't apply.
2. Find your zoning district and check Table 4.1. RS-12, RS-20, WW, IG, GR and GC are dead ends in the town. R, RU, RM, MDD, MTC and MVC mean a special permit, while CN, CR, IM and R-MI mean conditions and a site plan.
3. Confirm you can meet the primary-residence condition if you're in an R, RU or RM district, because no fee or filing substitutes for living there.
4. Count your bedrooms against your driveway. One off-street space per short term rental bedroom, on the same lot, is a hard condition and one of the easiest to fail on a narrow shoreline parcel.
5. Check whether you're inside the coastal boundary, since the April 2026 amendment removed the single-unit dwelling exemption from coastal site plan review.
6. Call the Office of Planning and Development Services before you file, get the current fee schedule, and ask whether an administrative site plan is available for your situation.
7. File the application, with the owner's signature and the plot plan, and expect a special permit to take a few months once the hearing timetable in Section 9.1-10 plays out.
8. Register for room occupancy tax only if you need to. Platform-only bookings are generally covered by the facilitator rules, whereas direct bookings mean registering with DRS and filing Form OP-210 monthly.
9. Keep the conditions. They bind the property, survive a sale, and an open violation will stop your next application cold.

Frequently Asked Questions

Can you legally run an Airbnb in Groton, Connecticut in 2026?

In parts of it, yes. The Town of Groton permits short term rentals in its R, RU, RM, MDD, MTC and MVC districts with a special permit, and in CN, CR, IM and R-MI with conditions and a site plan, while banning them in the single-unit residential, working waterfront, general industrial and green districts. In the R, RU and RM districts the owner or lessee must live on the lot. The Noank Fire District prohibits them in every district, and the City of Groton and Groton Long Point run separate regulations.

Does Groton require a short-term rental licence or registration?

No. The Town of Groton regulates short term rentals through zoning rather than through a registration ordinance, so approval attaches to the property rather than to the operator and is enforced by the zoning enforcement officer. The town's municipal code, current through August 5, 2025, contains no short-term rental chapter. What you need instead is site plan approval from the Planning and Zoning Commission, plus a special permit in most residential and mixed-use districts.

What taxes apply to a short-term rental in Groton?

Connecticut charges a 15% room occupancy tax on short-term home rentals and 11% on bed and breakfast establishments, and it applies only to the first 30 consecutive days of a stay. There's no town or county lodging tax in Groton. Booking platforms that qualify as short-term rental facilitators collect and remit it on bookings they handle, so hosts who book only through Airbnb generally don't file separately. Direct bookings require registering with the Department of Revenue Services for $100 and filing Form OP-210 monthly.

Are existing Groton short-term rentals grandfathered?

Uses that were lawfully in operation before the regulations changed can continue as non-conforming uses under Sections 9.7-3 and 9.7-4 of the town's zoning regulations, as long as they remain otherwise lawful. That protection is narrow, though. A non-conforming use can't be enlarged or relocated on the lot, can't be resumed once a permitted use replaces it, and ends if the owner abandons it. There's no register of protected properties either, so the burden of proving the prior lawful use falls on the owner.

What are the penalties for an illegal short-term rental in Groton?

Section 8-12 of the Connecticut General Statutes sets fines at not less than $10 and not more than $100 for each day a violation continues, rising to between $100 and $250 per day for a wilful offence, with up to ten days' imprisonment for each day of violation capped at thirty days. The Zoning Official can also order a violation remedied in writing and bring an action to restrain or abate it. The fine accrues daily, so a full season of unpermitted hosting adds up considerably.

Groton is a good reminder that a place name and a jurisdiction aren't the same thing. The question worth asking early isn't what the rules in a given town are, but whose rules reach your particular parcel, and plenty of coastal New England towns carry the same fragmentation in fire districts, boroughs and beach associations that predate modern zoning by a century. Find that answer before you buy, not after you list.
