Condo Insurance in Greenwich, CT

By Jon Merwin, Founder and CEO

A Greenwich condo might be an elevator building a short walk from Greenwich Avenue, a townhouse community off the Post Road, a garden-style cooperative near the train station, or a detached home in a planned community where the association owns little more than the roads. Many owners sold a larger house in town and wanted one-floor living without leaving Greenwich. All of them need a unit policy that fits the master policy exactly, with no gaps and no double coverage.

Portsmouth Atlantic Insurance is an independent, family-owned agency, founded in 2005. For Greenwich condo and co-op owners we compare 40+ carriers, add flood and umbrella coverage where it fits, and work with boards on master policies. We serve Connecticut from our Connecticut office and by phone, email and online. Call (603) 431-4020 to talk through your building.

Who owns condos in Greenwich

Greenwich is mostly a town of single-family houses, but not entirely. Of its roughly 25,610 homes, about 1,950 are townhouse-style attached homes and about 3,700 sit in buildings of five or more units, based on the 2020–2024 American Community Survey (Census B25024). Among the roughly 16,160 homes lived in by their owners, about 950 are attached units and about 1,390 are in buildings of five or more units (Census B25032). Most of those are condominiums or cooperative apartments.

Values are high across the board. The median owner-occupied home in Greenwich is valued at about $1.7 million, and about 6,990 owner-occupied homes are valued at $2 million or more, the top bracket the survey reports (Census B25075; B25077).

The town expects demand for this kind of housing to grow. Greenwich’s 2019 Plan of Conservation and Development names housing for an aging population as one of its two top housing needs and calls for age-friendly options with one-floor living, elevators and limited maintenance near walkable areas.

Condo, co-op or planned community: what you own decides what you insure

Connecticut’s Common Interest Ownership Act (CGS chapter 828) covers condominiums, cooperatives and planned communities. Its insurance, assessment and resale sections reach communities created before 1984 as well, although they do not override existing provisions in an older community’s declaration (CGS 47-216). The three forms look alike from the street, but the insurance works differently in each.

Condominiums

You own your unit outright, along with a share of the common elements. The declaration draws the line between the two, often at the inside face of the walls or the studs, and the master policy and your HO-6 divide the risk along that line.

Cooperatives

In a cooperative, the corporation owns the land and buildings, and you own shares that come with a proprietary lease on your apartment. Greenwich has long-established cooperatives close to downtown, among them Putnam Park, a 194-apartment complex of garden apartments and townhouses completed in 1950, and Putnam Hill. The corporation insures the structure, and under state law its liability policy must cover all of the units as well as the common areas (CGS 47-255). Your own policy covers your interior improvements, belongings, liability and extra living costs, and it should include loss assessment coverage for anything the corporation passes through to shareholders.

Planned communities and detached units

Some Greenwich communities are planned communities or “site” condominiums in which each owner’s home is a detached building. The state rule that pulls the units into the master policy applies to buildings where units are stacked or share walls. When your home stands on its own, you may be responsible for insuring the entire structure, which calls for a homeowners-style policy rather than a standard HO-6. The declaration tells you which it is, and getting this wrong leaves the whole house uninsured.

What Connecticut requires of the master policy

From the first sale by the developer, a Connecticut association has to carry property coverage on the common elements worth at least four-fifths of their actual cash value, general liability with medical payments, and fidelity coverage. It must also carry flood coverage if the community lies in a federally mapped flood hazard zone and a vote of the owners directs it. The statute qualifies all of this with “to the extent reasonably available” and allows reasonable deductibles (CGS 47-255(a)). Those are floors; many Greenwich master policies insure at replacement cost.

Four further provisions protect unit owners and rarely get read:

• You are an insured. The master policy must treat each owner as an insured for liability arising from their interest in the common elements or membership in the association.
• No subrogation against owners. The insurer must give up its right to pursue a unit owner to recover what it paid.
• Your acts cannot void it. Nothing an individual owner does, unless acting for the association, can void the master policy or block recovery under it.
• The master policy goes first. If your own policy covers the same risk at the time of a loss, the association’s policy is primary.

After a covered loss, the association adjusts the claim and the money is held for repairs first. Damaged property must be rebuilt promptly unless the community is terminated, repair would be illegal, or four-fifths of the owners, including every owner whose unit would not come back, vote not to rebuild.

Your improvements and the 2025 change to state law

Where units are stacked or share walls, the master policy is supposed to pick up the units and owners’ improvements and betterments too. Two things can take improvements off the table: language in the declaration, or a board vote taken after owners have had notice and a chance to comment. A community of more than 12 units that goes that route must describe, in a yearly schedule sent to owners, the standard fixtures and finishes its policy still covers. Everything above that baseline falls to you.

That baseline matters more in Greenwich than in most places, because owners here often take a unit down to the studs: custom millwork, stone and marble, a chef’s kitchen, heated floors, built-in audio and lighting controls, a wine room. Since 2025, Connecticut law also says that if an addition, alteration or improvement an owner makes raises the association’s costs, including the cost of maintenance, repair or insurance, the increase may be assessed to that owner’s unit alone (CGS 47-257(h)).

So before a major renovation, ask the board or manager in writing whether the master policy will insure the new work, then set your HO-6 building limit to match.

Building an HO-6 for a Greenwich unit

• Building property. Your improvements and anything the declaration makes your responsibility, at replacement cost. For a heavily renovated unit this can be the largest limit on the policy.
• Personal property. Furniture, clothing and electronics at replacement cost. Jewelry, watches, art and collections carry low limits for theft on a standard policy, so schedule them with current appraisals.
• Loss of use. Rental housing while your unit is repaired, including when the damage started in another unit or a common area.
• Personal liability. Injuries to guests and accidental damage to a neighbor’s unit, with a personal umbrella on top.
• Loss assessment. Your share of an association assessment after a covered loss, sized to the master deductible.
• Water backup. Usually an add-on, and worth having for garden-level units and buildings with shared drain stacks.

For high-value units we compare Cincinnati and Chubb alongside our other carriers, and we coordinate the unit with your cars, scheduled valuables and a personal umbrella so the liability limits line up. If you also own a house in town, see our Greenwich high-value home insurance page, and our condo vs. homeowners insurance guide for how the two policy types differ.

Deductibles and assessments

Repair costs beyond the insurance money and reserves, deductible included, are normally a common expense split among all owners (CGS 47-255(h)). When an owner or tenant caused the damage through gross negligence, deliberate misconduct or by ignoring a written maintenance standard, the board may, after notice and a hearing, put the uninsured part on that one unit (CGS 47-257(e)). Ask for the current master deductible at every renewal and read the maintenance standards; both decide how much loss assessment coverage you need.

Water, heat and time away

Water causes more condo claims than anything else. A refrigerator supply line, a washing machine hose or a leaking shower pan upstairs can reach several floors before anyone notices. Typically the association’s carrier repairs the structure above its deductible, while every affected owner turns to their own HO-6 for finishes, contents and temporary housing.

If you spend part of the winter away, keep the heat on, shut off the unit’s water if the building allows it and have someone look in. Leak sensors and automatic shutoffs are inexpensive. Tell us if the unit will sit empty for a long stretch, since many policies limit coverage for unoccupied homes.

Flood risk for Greenwich condos and co-ops

Greenwich’s section of the regional WestCOG hazard mitigation plan describes flood risk concentrated along the town’s rivers and its Long Island Sound shoreline. VE and AE flood zones run along the coast, an AE floodplain is mapped along Horseneck Brook, and the Byram River has its own regulated floodplain. It counts 117 repetitive loss properties, 109 of them residential and most on the coast, and names Sound Beach Avenue in Old Greenwich as a road where coastal and drainage flooding together cut off emergency access more often than in the past.

Two other points in the plan speak directly to condo communities. Town staff flagged privately owned roads whose associations do not always keep up the drainage, which can leave roads blocked or washed out. And Greenwich counts substantial improvements to buildings in flood zones cumulatively, in some cases as far back as 1986, so a string of renovation projects in a flood-zone building can add up to a requirement to bring the whole structure into compliance. Boards planning work in a mapped zone should talk to the town before they start.

Two layers of flood coverage

A building-wide flood policy for the association, whether the NFIP’s condominium association form or a private one, is only mandatory in Connecticut when the community is mapped in a hazard zone and owners have voted for it, so ask rather than assume. A unit owner’s own flood policy protects contents and can respond to some flood assessments. On the NFIP Dwelling Form, a unit owner’s building coverage can help with a flood assessment for damage to the unit or common elements, though never with one that passes along the association’s own flood deductible (FEMA Dwelling Form; FEMA RCBAP form). New NFIP policies generally carry a 30-day waiting period, with a few exceptions.

New NFIP flood policies go through Selective. Where the federal limits or terms fall short, our private and excess flood markets are Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge. Check your building’s zone with the FEMA Flood Map Service Center, and read our Greenwich and Westport shoreline flood insurance page and the Fairfield County flood insurance overview for more.

Renting out your unit

Greenwich zoning allows short-term residential rentals of fewer than 30 nights in its residential zones, for lodging only and with no parties, weddings, filming or similar events (Greenwich Building Zone Regulations). A condo declaration can be stricter, and many restrict leasing altogether or set a minimum lease term. If yours allows it, call us before the first tenant or guest arrives, because a policy written for owner occupancy does not fit a rental. Ask every tenant to carry renters insurance.

If you also own rental houses or small multi-family buildings in Fairfield County, our Stamford landlord insurance and Norwalk landlord insurance pages explain how dwelling policies work in Connecticut.

For boards and managers

A board’s insurance decisions land on every owner. With Greenwich boards we review the valuation basis against current construction costs, whether improvements are insured, the deductible and how the declaration allocates it, ordinance or law coverage, equipment breakdown for boilers, elevators and pumps, directors and officers liability, and fidelity coverage. If the association maintains private roads and drainage, look at the liability limit and an umbrella too.

For the association’s own coverage, Vermont Mutual, Andover and Providence Mutual are the carriers we use for Connecticut master policies; our Connecticut condo association insurance page has more. A master policy carrier that plans to cancel or not renew has to mail 60 days’ warning to the association and to any owner or lender it has issued a certificate to, and any owner may ask for one.

Before you buy a Greenwich condo

Connecticut’s resale certificate is the best insurance document a buyer gets (CGS 47-270). It must describe the insurance provided for unit owners, including any fixture schedule, along with the capital reserves, approved capital projects, pending lawsuits, leasing restrictions, the number of owners 60 or more days behind on common charges and any written maintenance standards. The purchase contract generally stays voidable until five business days after the certificate is delivered.

• Send us the insurance statement, fixture schedule and master declarations before you pick HO-6 limits.
• Ask whether the community carries flood coverage, and check the zone yourself.
• Confirm whether the unit is stacked, shares walls or stands alone.
• Ask about planned roof, elevator and drainage projects and any special assessments.

Frequently asked questions

Does the Greenwich master policy cover the inside of my unit?

Partly. Where units are stacked or share walls, Connecticut generally requires the master policy to include the units, but the declaration or a board decision can leave owner improvements out. Larger communities that do so must send owners a yearly schedule of what the master policy still covers. Your HO-6 picks up the rest.

I spent heavily renovating my unit. Is that covered?

Only if someone insures it. If the master policy leaves improvements out, your HO-6 building limit has to carry them. If it includes them, a 2025 change to state law lets the association charge the added cost of insuring or maintaining them to your unit. Either way, tell us what you changed.

How is insuring a Greenwich co-op different from insuring a condo?

The corporation owns the buildings and you hold shares and a proprietary lease, so the corporation insures the structure. You still need your own policy for improvements, belongings, liability, living costs and assessments. The proprietary lease says what you must repair.

Do I need flood insurance if my building is not on the water?

Consider it. Greenwich’s hazard plan maps flood zones along Horseneck Brook and the Byram River as well as the shore, and drainage flooding happens outside mapped zones. Your HO-6 excludes flood.

What is loss assessment coverage and how much should I carry?

It pays your share when the association bills owners for a covered loss, including a share of the master policy deductible. Size it against that deductible and the number of units it would be split among, and check it again whenever the board changes the deductible.

Can I rent my Greenwich condo short term?

Check the declaration first; an association can restrict leasing even where town zoning allows stays of under 30 nights. If renting is allowed, tell us before the first guest arrives.

What should I send to get a quote?

The master policy declarations, any fixture schedule, your square footage, a list of improvements and appraisals for valuables. Call (603) 431-4020 or use the form on this page. Request a quote. There’s no obligation to buy.
