New Canaan at a glance

The U.S. Census Bureau estimates 21,208 New Canaan residents as of July 1, 2025 (20,589 in the April 2020 estimates base). The town’s New Canaan Municipal Annex (August 2021) is part of the WestCOG Multi-Jurisdiction Hazard Mitigation Plan 2021–2026, which WestCOG says stays active through December 2026 while it prepares the 2026–2031 update.

The annex says New Canaan borders Darien, Wilton, Norwalk, Stamford and New York State. The Fivemile River runs north to south through the center of town, the Silvermine River along the eastern border, and the Noroton River starts in the northwest-central part of town. Citing the 2016 Plan of Conservation and Development, it says 97% of the town is developed or committed, mostly to single-family lots.

The annex traces the town’s growth to the railroad in 1868, when wealthy New Yorkers built summer homes and later settled year-round. It lists the Church Hill and New Canaan historic districts, the Merritt Parkway, and a number of properties on Ponus Ridge Road among its historic resources.

What drives home insurance in New Canaan

• The Fivemile River. The annex calls the area along the Fivemile the town’s primary flood risk tied to mapped floodplain, and says New Canaan completed a drainage and flood mitigation study of the river.
• Poor drainage. The annex notes drainage problems on Southwood Drive, Old Stamford Road and in Waveny Park.
• Trees and outages. The annex says blocked roads or loss of power from falling trees is a primary concern, and that the main risk from tropical storm winds is downed trees and limbs.
• Private wells. Public water reaches only parts of town, along Danbury Road, the Westport Road area and Silvermine, the annex says; much of the rest of New Canaan depends on private wells.

Mid-century modern and architect-designed houses

Philip Johnson’s Glass House, now a National Trust for Historic Preservation site, is the best-known example, but many private modern houses remain in town, including work by the architects known as the Harvard Five. Large panes of glass, radiant heating, and flat or low-slope roofs are things underwriters ask about. We document original materials and any renovations so your dwelling limit reflects what it would really take to rebuild.

Flat and low-slope roofs also matter in winter. The annex notes that neighborhoods with many flat roofs are more exposed in snow and ice storms, so keep snow and drains clear on a modern house.

Renovations and teardowns

Major renovations and rebuilds are common in New Canaan. If the house will be partly empty or under construction, many policies limit coverage, and a builder’s risk policy may be needed. Tell us before work begins, and again when the project is finished so the new square footage and finishes are insured.

Flood coverage in New Canaan

The annex says New Canaan has been in the NFIP since July 19, 1974, that its flood maps were last revised in 2010, and that the town requires two feet of freeboard above flood elevation, more than many neighboring towns. Regulated AE floodplain is mapped along the Rippowam and Silvermine Rivers, with other flood storage areas mapped as Zone A.

All six of the town’s repetitive loss properties are homes, most of them on the Fivemile River. The annex says the town has helped some owners file Letters of Map Amendment with FEMA. If you are near the Fivemile, the Silvermine or the Noroton, price flood even if your lender does not require it.

A homeowners policy will not pay for a river or brook over its banks, or surface water. Flood is its own policy. Check your address on the FEMA Flood Map Service Center and ask us to compare NFIP and private flood.

• NFIP through Selective. We write National Flood Insurance Program policies through Selective, a Write Your Own carrier. The NFIP covers up to $250,000 for the building and $100,000 for contents. New policies generally have a 30-day waiting period (see FloodSmart), so buy before storm season, not during it.
• Private flood. When a home costs more than the NFIP limit to rebuild, we compare Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge, address by address.
• Elevation certificates. If you have one, send it. A raised house or flood vents can change how flood carriers rate it.

Water backup (sewer, drain or sump pump failure) is an add-on to homeowners; flood is separate. If your basement is finished, ask about both. See basement flooding coverage, our flood insurance overview and our Fairfield County flood insurance guide.

Other hazards in the New Canaan annex

Wildfire. The annex rates New Canaan as moderate risk for small wildfires and low risk for large ones, with small pockets of concern outside the built-up parts of town, especially where there is no public water.

Wind. The annex says most of the housing stock predates recent building code changes and may be more exposed to roof and window damage in high winds.

Trees, wind and winter claims

The annex says New Canaan received $435,347 in public assistance after Winter Storm Alfred in October 2011, and that ice can bring down power lines and cause damage from frozen pipes. Storms such as the 2011 nor’easter and Tropical Storm Isaias in 2020 left parts of Fairfield County without power for days.

Fallen trees, wind, snow-load roof damage, ice dams and frozen pipes are generally homeowners claims, subject to your deductible. A tree that falls without hitting anything usually is not covered. A burst pipe is usually covered when the home is heated and occupied, so tell us if it will sit empty. A generator, low-temperature alarm and water leak shutoff prevent the largest winter losses.

Larger homes

For most homes, almost all of our 40+ carriers can fit, so we compare the full field. Cincinnati and Chubb are both high-value carriers we can quote. Whatever the size, we build the dwelling limit around the cost to rebuild, not the market value, and look at extended or guaranteed replacement cost where offered.

Many New Canaan homes, modern or traditional, cost far more to rebuild than a market estimate suggests. See high-value home insurance in Connecticut and New Canaan high-value home insurance.

Rentals, condos and older homes

Your HO-6 condo policy covers what the association’s master policy does not: usually your interior, improvements, belongings, liability and loss assessments. If you rent out a house in New Canaan, you need a dwelling or landlord policy, not a homeowners form; we place Connecticut landlord and dwelling policies with Vermont Mutual, Andover, Liberty Mutual, Hanover and Foremost. It covers the building, lost rent and your liability. For an older colonial or an early modern, carriers will ask the age of the roof, heating, wiring and plumbing, and what has been renovated.

Renters and tenants in New Canaan

If you rent in New Canaan, your landlord’s policy covers the building, not your belongings or your liability. A renters policy covers both, plus extra living costs after a covered loss. Progressive Home is one of the carriers we shop, for renters policies only.

Auto, umbrella and the rest of the household

Most New Canaan households also need auto insurance, and many add a personal umbrella. New Canaan drivers rely on the Merritt Parkway and local roads lined with trees, so roadside coverage is worth a look, and households with teen drivers benefit most from an umbrella. We quote them with the home so the liability limits line up. One agent, one renewal conversation.

Common coverage gaps we see in New Canaan

• A dwelling limit based on the purchase price or assessed value instead of the cost to rebuild
• No water backup coverage on a house with a finished basement
• Liability limits on the home and auto that do not line up with an umbrella, or no umbrella at all
• No ordinance or law coverage on an older home that would need code upgrades after a loss
• A renovation finished but never reported, so the new space is not insured
• No plan for a well pump and heat in a long outage
• Art, jewelry and design pieces left unscheduled

Most are easy to fix once someone reads the declarations pages side by side, which is the first thing we do.

Before storm season in New Canaan

• Know your hurricane or named-storm deductible in dollars, not just as a percentage
• Photograph each room so a contents claim is easier to document
• If you want flood coverage, buy it well ahead of a storm because of the waiting period
• Clear snow and drains on flat and low-slope roofs
• Have an arborist look at large trees near the house, the driveway and the power line

Buying a home in New Canaan

Start the insurance conversation before you are under contract. Send us the listing and the inspection report, which answers most of what carriers ask. For a modern house, ask for the original plans and a record of renovations. Near the Fivemile River, ask for any elevation certificate, any Letter of Map Amendment and the seller’s flood history. We line up proof of homeowners coverage, and flood coverage if you need it, so both are ready for your lender.

How a New Canaan home quote works

• Tell us about the house: address, year built, square footage, roof age and system updates.
• Send your declarations page so we can compare like for like.
• We shop the carriers that fit and lay out coverage, deductibles and storm terms side by side.
• You choose, and we handle the switch, including your mortgage company, so there is no gap.

Frequently asked questions

Do you insure homes in New Canaan, CT?

Yes. We serve Connecticut from our Fairfield office at 1885 Post Road and by phone, email and online. Call (203) 859-6858.

Does New Canaan flood?

Locally. The 2021 WestCOG hazard mitigation annex counts six repetitive flood loss properties, all residential and mostly on the Fivemile River, and notes drainage problems on Southwood Drive, Old Stamford Road and in Waveny Park. Check your address on the FEMA Flood Map Service Center.

How do you insure a mid-century modern house?

We start with a replacement-cost estimate that reflects the original materials, glass and roof, document renovations, and compare carriers that write custom homes.

Do I need different coverage during a renovation?

Often, yes. Many policies limit coverage when a house is vacant or under construction, and a builder’s risk policy may be needed. Tell us before work begins.

Does homeowners insurance cover a flooded basement?

Not from flood. Water backup from sewers, drains or a sump pump is an add-on, and rising or surface water needs a flood policy.

Who writes your NFIP flood policies?

We write NFIP policies through Selective, and we compare private flood from Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge.

Do I have to buy if I request a quote?

No. Requesting a quote doesn’t obligate you to buy anything, whether it’s for homeowners, condo, renters, landlord, dwelling or auto coverage.
