Sunapee vs. New London, NH: Two Counties, Two STR Rulebooks
Sunapee and New London share a lake, a chamber of commerce headquartered in New London, and a general sense from the outside that they're one market. They do not share a county, a regulatory desk, or even the same basic structure for what a short-term rental is legally allowed to be. This post lays the two towns' rules side by side, plainly, for a host or buyer who needs to know which file actually applies to their specific property, drawing on the same sourced figures established in post one and post three.
This is not legal advice. It's a direct comparison built from each town's own posted materials, meant to prevent the mistake of assuming one town's rule, fee, or process applies across the town line just because the properties sit close together on the same shoreline. Read it before deciding how to market, price, or finance a property on either side of that line, and confirm the specific parcel's actual town before applying any of the guidance laid out below.
Sunapee: Sullivan County, a Permit, and a Day Cap
Sunapee sits in Sullivan County and runs a specific, structured system, distinct from anything New London requires: an annual permit required before advertising, filed through the town's OpenGov portal, with the relevant office at 23 Edgemont Road. An owner-not-in-residence rental is capped at 120 days within a 12-month period, occupancy is capped at 16 guests using a two-per-bedroom-plus-one formula, and the zoning ordinance, Article IV Section 4.95, requires a Special Exception in the Rural Residential district while prohibiting the use outright in Rural Lands.
The permit fee itself is currently unsettled between two sources: the Selectboard's February 23, 2026 fee schedule lists $300 new and $150 renewal, while the town's own regulations page, still hosted live, lists a flat $350. Both figures are cited here rather than picking one, and a host or buyer should confirm the current figure directly with the town rather than relying on either source alone. No phone number for Sunapee's offices is cited in this post — none was confirmed, and none should be assumed.
New London: Merrimack County, a Different Structure Entirely
New London sits in Merrimack County, with town offices at 375 Main Street. This research did not find a dedicated short-term rental permit process comparable to Sunapee's — no equivalent annual permit, no comparable fee schedule. Instead, New London's zoning approach defines short-term rental as an accessory use limited to stays under 90 days, a structural rule embedded in the town's zoning ordinance rather than a separate permit-and-day-cap system.
One correction worth stating plainly: a ban on short-term rental use in accessory dwelling units has appeared in New London's 2024 proposed zoning packets, but it is not part of the town's adopted current ordinance as confirmed in this research. Do not present that ADU restriction as settled New London law; treat it as a proposal that was under discussion, not a rule currently in force, unless you confirm its adoption status directly with the town before relying on it.
The Revenue Numbers, on Their Own Lines
AirROI's town-scale figures put Sunapee at $31,118 across 71 listings and New London at $32,552 across 47 listings, trailing twelve months. The two towns' revenue reads sit close together in dollar terms, which makes it easy to forget how differently the two regulatory files actually work underneath that similar number. Never average these two figures — they describe two different towns with two different legal operating frameworks, not one blended lake market.
AirDNA's competing $49.4K figure is a single catchment spanning Sunapee, New London, and Newbury pages alike, not two separate town years the way the AirROI figures are. Citing it as if it independently confirms both towns' revenue potential misrepresents what that number actually measures.
Same Lake, Different Operating Discipline
A property a few hundred yards apart on opposite sides of the town line is operating under genuinely different rules, different fee structures — or, on the New London side, the apparent absence of a published permit-fee schedule at all — and different county-level offices. A Sunapee host is managing a hard annual day-count against a permit process; a New London host is managing a hard nightly-length ceiling against an accessory-use zoning definition. Those are two different operating disciplines, not two versions of the same rule with different numbers plugged in.
A host or buyer treating "Lake Sunapee" as one regulatory environment because it's one lake will get this wrong in a way that has real compliance consequences — filing for the wrong town's permit, assuming a day cap where a stay-length ceiling actually applies, or budgeting for a fee schedule that doesn't exist in the other town. Pull current contacts for each town's planning or zoning office directly before relying on secondhand information; this post does not include a phone number for either town, since none was confirmed to this research's standard.
A Side-by-Side Summary Worth Keeping Handy
Sunapee: Sullivan County, town office at 23 Edgemont Road, annual permit required before advertising through the OpenGov portal, 120-day cap for owner-not-in-residence rentals, 16-guest occupancy ceiling, Special Exception required in Rural Residential, prohibited outright in Rural Lands, and a currently unsettled permit fee between $300/$150 and a flat $350. New London: Merrimack County, town offices at 375 Main Street, no dedicated short-term rental permit process found in this research, short-term rental defined as an accessory use under 90 days, and a proposed but not adopted ADU-STR ban that should not be presented as current law.
Keeping this comparison in one place matters because the two towns' rules are genuinely easy to conflate given how close the properties sit geographically. A host managing listings in both towns, or a buyer comparing parcels across the town line, benefits from treating this summary as a quick-reference check before any major decision, rather than relying on memory of which rule applies where.
What a Buyer or Host Gains From Understanding Both Files
Even a host who only owns property in one of these two towns benefits from understanding the other town's rule, because guests, lenders, and even local officials sometimes assume the two towns share a regulatory framework simply because they share a lake. A Sunapee host who can clearly explain why New London's rule doesn't apply to their property — and vice versa — is better equipped to correct that assumption quickly and accurately, whether it comes up in a guest question, a lender conversation, or a casual comparison with a neighboring host across the town line.
Why Two Such Different Systems Developed on the Same Lake
This research doesn't include a confirmed account of exactly why Sunapee and New London arrived at such different regulatory approaches, and this post doesn't speculate on that history. What's confirmed is the outcome: two adjacent towns, sharing a lake and a chamber of commerce, arrived independently at genuinely different frameworks for governing the same underlying activity. That's worth noting as a reminder that municipal boundaries in New Hampshire carry real regulatory weight even where a shared geography might suggest otherwise — a pattern not unique to this lake, but one that shows up here with unusual clarity given how closely the two towns' properties sit to one another.
The Practical Bottom Line for a Two-Property Owner
A host or investor who ends up owning in both towns should expect to run two genuinely separate compliance calendars, not one combined checklist. Sunapee's calendar centers on an annual permit renewal and tracking the 120-day allowance across the year. New London's calendar centers on confirming every individual booking stays under the 90-day accessory-use ceiling, without an annual permit renewal date to anchor the process. Treating these as one unified system, rather than two separate ones running in parallel, is the single most common structural mistake a two-property owner in this market can make.
How This Comparison Should Shape a First-Time Buyer's Search
For a buyer who hasn't yet chosen between the two towns, this comparison is worth reading before, not after, narrowing down specific listings. A buyer who values operating a property closer to its full seasonal capacity, and who's comfortable navigating a permit and, potentially, a Special Exception process, may find Sunapee's structure a better fit despite the lower day-count ceiling. A buyer who prefers a simpler, if less exhaustively documented, regulatory picture and is comfortable operating within a tighter 90-day stay-length ceiling may find New London's posture easier to work within day to day, even without a comparable permit system to lean on for compliance documentation.
Neither preference is right or wrong in the abstract — it depends on the buyer's own risk tolerance, available time for compliance administration, and intended booking pattern. What matters is making that choice with both towns' actual rules in view, rather than discovering the difference only after an offer is already in on a specific parcel.
A Reminder About What This Post Doesn't Cover
This comparison is scoped specifically to each town's short-term rental regulatory posture — permits, day caps, and zoning restrictions. It doesn't cover general property taxes, homeowners' insurance considerations, or broader municipal services comparisons between the two towns, none of which were confirmed to this research's standard and none of which belong in a short-term rental rules comparison specifically. A buyer weighing the two towns on those broader dimensions needs separate research beyond what this cluster provides.
Confirming Your Property's Actual Town Before Anything Else
Before applying either town's rule to a specific parcel, confirm which town the property is actually in, using the relevant county's GIS system or the property's own deed and tax records, rather than assuming based on the property's marketed address or its proximity to the lake's more famous features. This sounds like an obvious first step, but given how close some parcels sit to the Sunapee-New London town line, it's a genuine source of confusion worth resolving with an authoritative source before any of the rest of this comparison gets applied to a real purchase or listing decision.
Why a Listing's Marketing Copy Should Reflect This Comparison Too
This comparison isn't purely a compliance exercise — it has a direct marketing implication covered more fully in post two. A listing that accurately reflects its town's actual operating rule, in its calendar and its description, reads as more credible to a guest who's done any research at all into short-term rental regulation before booking. A listing that vaguely implies flexibility neither town's rule actually supports risks both a compliance problem and a guest-trust problem simultaneously, which is exactly the kind of avoidable mistake this side-by-side comparison is meant to prevent.
Revisiting This Comparison as New London's Rules Evolve
New London's 2024 proposed zoning packets, including the ADU-STR ban this post is careful not to present as adopted law, are worth watching for future adoption. If New London's zoning ordinance changes in ways that add a permit process, adjust the stay-length ceiling, or formally adopt the ADU restriction, this comparison would need updating to reflect the new current text. Treat New London's regulatory posture as more likely to shift in the near term than Sunapee's, precisely because the 2024 proposed packets signal the town was actively considering changes as of this research, separate from Sunapee's own ongoing 2026 debate covered in post thirteen. A host or buyer relying on this comparison for a long-term decision should build in a periodic re-check of New London's current adopted ordinance text specifically, not just Sunapee's.
Two Renewal Calendars, Not One Shared Reminder
A host operating in both Sunapee and New London is tracking two genuinely different compliance calendars, not one shared reminder that happens to apply twice. Sunapee's permit renewal and the 120-day cap tracking under ONIR run on their own schedule, tied to that town's specific ordinance and OpenGov system, while New London's structure, built around the accessory-use classification rather than a standalone STR permit, has its own separate rhythm.
Building one shared calendar reminder for both properties risks missing a Sunapee-specific renewal date because it was folded into a general 'check STR compliance' reminder that doesn't actually reflect either town's specific requirements. A cleaner approach is keeping two separate, explicitly labeled tracking entries, one for each town, each tied to that town's own actual deadlines and requirements rather than a blended assumption.
This same discipline extends to how you'd brief a property manager, a bookkeeper, or anyone else helping manage either property. Naming the specific town, Sunapee or New London, in every compliance conversation, rather than referring generally to 'the lake property' when you own more than one, keeps the two files from getting quietly merged by someone helping you who wasn't the one who originally learned the distinction.

Frequently Asked Questions
Which county is Sunapee in, and which is New London in?
Sunapee is in Sullivan County. New London is in Merrimack County. This isn't just an administrative detail — it means the two towns' permit offices, zoning boards, and property-tax registries are entirely separate systems, even though the towns sit on the same lake.
Does New London have a short-term rental permit like Sunapee's?
This research did not find a dedicated New London short-term rental permit process comparable to Sunapee's annual permit and fee schedule. New London's approach instead defines short-term rental as an accessory use under 90 days within its zoning ordinance, a structurally different system rather than a permit-based one.
What's the maximum rental period in each town?
Sunapee caps an owner-not-in-residence rental at 120 days within a 12-month period. New London limits short-term rental, as an accessory use, to stays under 90 days per booking. These are different kinds of limits entirely — an annual day-count total versus a per-stay length ceiling — not two versions of the same rule.
Are accessory dwelling units banned from short-term rental use in New London?
Not under the town's currently adopted ordinance, based on this research. An ADU-STR ban appears in New London's 2024 proposed zoning packets, but it is not confirmed as part of the town's adopted current rule. Don't present it as settled law without confirming its adoption status directly with the town first.
What's the current Sunapee permit fee?
Two figures currently exist: the Selectboard's February 23, 2026 fee schedule lists $300 for a new permit and $150 for a renewal, while the town's own regulations page lists a flat $350. Confirm the currently enforced figure directly with the town rather than relying on either source alone.
Is there a comparable fee figure for New London?
No. This research didn't find a published permit-fee schedule for New London, consistent with the absence of a dedicated STR permit process there. Don't guess or assume a New London fee figure based on Sunapee's system; the two towns' regulatory structures aren't parallel.
Can I average Sunapee's and New London's revenue figures into one Lake Sunapee number?
No. AirROI shows Sunapee at $31,118 and New London at $32,552, on separate town-scale extracts. The two towns operate under different regulatory files entirely, and averaging their revenue into one figure obscures a real, meaningful difference in what each town's number actually represents.
Does AirDNA's $49.4K figure independently confirm both towns' revenue potential?
No. It's a single catchment spanning Sunapee, New London, and Newbury pages alike, not two separate town-specific years. Citing it as independent confirmation for either town misrepresents what the figure actually measures — a regional aggregate, not a town result.
Where are each town's offices located?
Sunapee's relevant office is at 23 Edgemont Road. New London's town offices are at 375 Main Street. No phone number for either office is included here, since none was confirmed to this research's standard; contact each town directly through its own official channels.
If my property is near the town line, how do I know which rules apply?
Confirm the property's specific municipal boundary and zoning district directly with the relevant county's GIS or assessing office before assuming either town's rule applies. A property a short distance apart on opposite sides of the line can fall under entirely different regulatory files, so proximity alone doesn't tell you which town's rule governs.
