If you buy in Griswold, the first question to ask is whether the house is inside the Borough of Jewett City — because that changes your mill rate from 27.87 to 31.72. On a median-priced house that is roughly $970 a year, every year, and it is a lien on the property. Meanwhile Griswold's median rose 10.8% to $360,000 on 102 sales.

Price up 10.8%, volume essentially flat, pace essentially flat, and the premium over asking narrowing from 102.0% to 100.9%. That last movement is the interesting one. Griswold appreciated meaningfully while the bidding intensity eased. Houses are still clearing above list — just barely — but the frantic overbidding has moderated. For a buyer, that is a market where a well-reasoned offer at or slightly above asking is now competitive, rather than one where you needed to leap. For a seller it means pricing accuracy matters more than it did a year ago.
At $360,000, Griswold is one of the more attainable towns in New London County while sitting within reasonable reach of Norwich, the Route 395 corridor and the shoreline employers.
This is the thing to get right before you write an offer in Griswold, and it is the thing most often discovered too late.
Griswold contains an incorporated borough — the Borough of Jewett City — which levies its own tax on top of the town rate.
Where the house is | Total mill rate |
Griswold, outside the borough | 27.87 |
Griswold, inside the Borough of Jewett City | 31.72 (27.87 + 3.85) |
On a $360,000 house assessed at 70% of market value — an assessment of $252,000 — the difference is about $970 a year. Over a ten-year hold that is roughly $9,700, and it is capitalized into what the house is worth.
Connecticut special taxing district taxes are not a bill you can ignore. Under Connecticut General Statutes §7-328, district taxes are a lien on the property and can be enforced by foreclosure — the same mechanism the town has. And under §7-325 the district's boundaries must be recorded in the town land records, which is the good news: a proper title search will find it.
What I tell buyers to do, specifically:
One. Ask the listing agent in writing whether the property is inside the borough. Get it in writing.
Two. Have your attorney confirm it against the recorded boundary during the title search — do not rely on the listing.
Three. Get a paid-to-date letter from the borough before closing, exactly as you would from the town.
A buyer who skips this does not find out at closing. They find out on the first borough tax bill, and by then the mortgage payment is already set.
The Borough of Jewett City was incorporated in 1895. Its scale is worth understanding because it is unusual:
Roughly 3,328 people live in about 0.8 square miles. That is close to 29% of Griswold's population living on about 2% of its land.
So Griswold is really two housing markets. The borough is a compact, walkable, historic New England village center with older housing stock, sidewalks and services close together. The rest of Griswold is rural and semi-rural — larger lots, wells and septic, more land. Same town, same school system, genuinely different way of living, and a 3.85-mill difference in what you pay for it.
Neither one is better. But you should know which one you are buying, and a buyer who searches "Griswold" without understanding this is comparing houses that are not comparable.
This is a genuinely unusual feature and it is worth knowing.
The Jewett City Department of Public Utilities has operated as a municipal electric utility since 1897, sourcing power through CMEEC, the Connecticut Municipal Electric Energy Cooperative. Municipal electric utilities are rare in Connecticut — most of the state is served by the large investor-owned utilities.
The department contributes financially to the borough each year specifically to help stabilize borough tax rates. That is a real offset against the 3.85 mills, and it is a structural reason the borough rate has stayed where it is.
If you are buying inside the borough, ask about the utility during diligence — rate structure and reliability differ from the investor-owned utilities and it is a live part of the cost of owning there.
Griswold's next revaluation is the October 1, 2026 Grand List — this fall — affecting bills in July 2027.
What that means for anyone buying now: the assessment on the house you are looking at is about to be redetermined. Every assessment in town resets to current market value, the grand list grows, and the mill rate falls to compensate. Whether your specific bill rises or falls depends entirely on whether your assessment moves more or less than the town average.
Given that Griswold's median has risen from $325,000 to $360,000 and appreciation has not been uniform across the town, expect winners and losers. The published mill rate after the revaluation will look dramatically lower and will tell you nothing about your bill. Multiply the new assessment by the new rate. That is the only calculation that matters.
It also means that if you are buying in Griswold in 2026, you should be conservative about projecting your carrying cost forward. Budget for the possibility that your bill moves.
Griswold runs its own PK–12 district and — unusually for a town this size — has its own high school, which puts it ahead of most of its neighbors. Preston, Bozrah, Franklin, Lisbon, Sprague and Voluntown all send high schoolers out of town.
The structure is a K–4 elementary school and a 5–8 middle school, then Griswold High School, and the notable part is that the entire district sits on a single 70-acre campus.
That is a practical advantage worth naming. Families with children spread across grade levels deal with one location, one bus system, one set of drop-offs. Siblings stay physically together. Athletics and facilities are shared rather than scattered. For a household with a kindergartner and a tenth grader, this removes a daily logistical problem that most towns simply live with.
Griswold High School is also one of the destinations that neighboring Preston and Voluntown students can choose, which speaks to how it is regarded regionally.
This is worth stating plainly because it explains part of Griswold's tax picture.
Town | FY2027 grant | Per resident |
Preston | $1,165,290 | ~$243 |
North Stonington | $880,690 | ~$171 |
Ledyard (hosts Foxwoods) | $1,391,000 | ~$90 |
Montville (hosts Mohegan Sun) | $1,446,162 | ~$79 |
Norwich | $2,360,229 | ~$59 |
Griswold | $55,478 | ~$4.87 |
Griswold receives about $4.87 per resident from the Mashantucket Pequot and Mohegan Fund. Preston, a smaller town not much farther from the casinos, receives about $243. That is a fifty-fold difference per person.
Why it matters to you: several towns in this county have their mill rates meaningfully subsidized by this money. Griswold does not. Its rate is what it is because its own taxpayers fund its own budget, including a full PK–12 district with its own high school. When you compare Griswold's 27.87 to a neighbor's lower number, that is part of the explanation.
The statutory formula behind the distribution could not be verified — the state's explanatory pages were not reachable. The dollar amounts come from Connecticut's own statutory aid data and are solid.
Griswold is well outside the crumbling-concrete foundation area. The 20-mile radius defining Connecticut's crumbling foundation program is centered on the former J.J. Mottes Concrete Company in Stafford Springs, far to the northwest. It shapes diligence in Tolland and Windham County; it is not a Griswold issue.
Septic and well permits go through the Uncas Health District, which serves Griswold along with Bozrah, Franklin, Lebanon, Lisbon, Montville, Norwich, Preston, Salem, Sprague and Voluntown. Outside the borough, Griswold is largely well and septic — pull the Uncas permit history on any house you are serious about. Inside the borough, expect public water and sewer, which is one of the things the higher rate pays for.
Griswold sits along the Quinebaug River with Route 395 running through it, which is why a town this affordable is still a manageable commute to Norwich, the casinos, Plainfield and the Route 6 corridor.
You had a 10.8% price year on steady volume. That is a good market. But the percent of list slipped from 102.0% to 100.9%, which tells me buyers have gotten more disciplined — and that pricing accuracy now matters more than it did last spring.
Three things I would prepare.
State the borough status in the listing, whichever way it goes. If you are outside the borough, that is a selling point worth $970 a year and you should say so. If you are inside it, disclose it with the utility context — the borough gives you sidewalks, services, public water and sewer, and a municipal electric department that has been operating since 1897. Buyers who learn about a 3.85-mill district from their attorney a week before closing renegotiate. Buyers who read it in the listing simply price it in.
Get ahead of the revaluation. Griswold revalues this fall. Buyers will ask what happens to their taxes. The honest answer — assessments reset, the rate drops to compensate, and the outcome depends on your individual assessment — is the answer a credible seller gives.
If you have school-age children, mention the single campus. It is a real quality-of-life advantage and almost no listing in Griswold ever says it.
If you want a real number for your home, I will walk the property, pull the actual comparables for your side of the borough line, and tell you honestly what I think it brings.

27.87 mills outside the Borough of Jewett City. Inside the borough, add 3.85 for a total of 31.72. On a $360,000 house assessed at 70% of value, the borough difference is about $970 a year. Confirm which side of the boundary a property sits on before you make an offer.
An incorporated borough inside the Town of Griswold, established in 1895, levying its own 3.85-mill tax on top of the town rate. About 3,328 people live in roughly 0.8 square miles — some 29% of Griswold's population on about 2% of its land. Borough taxes are a lien on the property under Connecticut General Statutes §7-328 and can be foreclosed; boundaries are recorded in the town land records under §7-325, so a proper title search will find them.
Yes. The Jewett City Department of Public Utilities has operated as a municipal electric utility since 1897, sourcing power through CMEEC. It contributes financially to the borough each year specifically to help stabilize borough tax rates. Municipal electric utilities are rare in Connecticut.
On the October 1, 2026 Grand List — this fall — affecting bills in July 2027. Every assessment resets to current market value and the mill rate falls to compensate. Whether your bill rises or falls depends on whether your assessment moves more or less than the town average, not on the new rate number.
Yes. Griswold runs a full PK–12 district — a K–4 elementary school, a 5–8 middle school and Griswold High School — with the entire district on a single 70-acre campus. Neighboring Preston, Bozrah, Franklin, Lisbon, Sprague and Voluntown all send high schoolers out of town.
Griswold receives $55,478 for FY2027 from the Mashantucket Pequot and Mohegan Fund — about $4.87 per resident, against roughly $243 per resident for Preston. The formula reflects reservation adjacency and historical impact. It means Griswold's mill rate is funded by its own taxpayers to a far greater degree than several of its neighbors' are.
No. Griswold is far outside the 20-mile radius around the former J.J. Mottes Concrete Company in Stafford Springs that defines Connecticut's crumbling foundation program area.
