Landlord Insurance in Greenwich, CT

By Jon Merwin, Founder and CEO

Renting property in Greenwich rarely looks like renting anywhere else. One owner leases a waterfront house for a year to a family new to the area. Another keeps a furnished home for summer tenants, or rents the carriage-house apartment behind the main house. A third holds a two-family in Byram or Glenville that has been in the family for decades, or an inherited house that sits in an estate while the heirs decide what to do. Each needs a different policy, and many owners have two or three at once.

Portsmouth Atlantic Insurance has been an independent agency, owned and run by our family, since 2005. For Greenwich rentals we shop 40+ carriers for dwelling, liability, flood and umbrella coverage and line it all up with your own home and cars. Reach us at (603) 431-4020.

Greenwich’s rental market in numbers

The Census Bureau’s 2020–2024 survey counts about 23,090 occupied homes in Greenwich, and about 6,930 of them, roughly three in ten, are rented (B25003). About 1,850 rented homes are detached houses, more than a quarter of all rentals, while about 1,400 are in two-unit buildings, roughly 940 sit in buildings of three or four units, and about 1,810 are in larger buildings of five or more units (B25032).

Rents run high. Of the roughly 6,570 rentals with a cash rent, about 2,380 rent for $3,500 a month or more, the top bracket the survey reports (B25063). Another 756 homes sit vacant because they are held for seasonal, recreational or occasional use (B25004). For an owner, that means a single uninsured month can be a large loss, and fair rental value coverage is worth sizing carefully.

The buildings are old. About 6,560 Greenwich homes were built in 1939 or earlier, roughly one in four, and more than two-thirds date from before 1980 (B25034). Older wiring, heating plants, plumbing and lead paint are the first things a landlord carrier asks about.

Where Greenwich’s multi-family houses are

Greenwich grew as a set of villages. The town’s 2022 Affordable Housing Plan describes mill communities such as Glenville, Cos Cob, North Mianus and Riversville that grew up along the rivers in the 18th and 19th centuries, and neighborhoods such as Byram, Chickahominy and Glenville that have some but not all of the services of a village center. Many of the town’s older two- and three-family houses stand in these village neighborhoods.

Byram sits on the western edge of town, where the Byram River runs south to Long Island Sound along the New York line. Glenville and Pemberwick follow the same river upstream. Chickahominy lies just west of downtown. A two-family in any of them is a different underwriting file from a leased estate in back country, and we treat it that way.

Matching the policy to the property

Houses and condos you lease out

Property you lease to others without living there belongs on a dwelling fire form. Of the two common versions, the basic DP-1 names specific perils and tends to settle at actual cash value, while the DP-3 covers the structure for anything not excluded and generally settles at replacement cost; we usually start with the DP-3. The carriers we turn to for Connecticut rentals of one to four units are Vermont Mutual, Andover, Liberty Mutual, Hanover, Providence Mutual and Foremost. A leased condo also needs a unit policy that allows tenants and fits the association’s master policy.

When you live in one of the units

If you live in one unit and rent the others, many carriers will write the whole building on a homeowners form, which picks up your own belongings and personal liability along with the structure and the rental units. For that route we look at Vermont Mutual, Andover, Providence Mutual, Liberty Mutual, Hanover, Foremost, Openly, Stillwater, Cincinnati and National General. See landlord insurance vs. homeowners insurance for how the two approaches compare.

Carriage houses, cottages and accessory units

Greenwich voted in 2022 to opt out of the state’s accessory apartment mandate and rewrote its own accessory dwelling unit rules in 2023. A property may have one accessory unit, inside the main house or in a separate building such as a carriage house or converted garage. The record owner must live in either the main house or the accessory unit and file an affidavit every year, and the owner must keep title to both. Detached units are capped at 800 to 1,200 square feet depending on the zone, and the accessory unit needs its own off-street parking space (Greenwich ADU regulation). Separate staff quarters with their own kitchen are allowed only if they meet the same accessory unit rules.

For insurance, the key point is that a rented carriage house is still part of an owner-occupied property, so it usually stays on your homeowners policy, with an important exception. Standard homeowners forms generally exclude other structures rented or held for rental to someone who is not a tenant of the main house, unless the building is used only as a private garage. An endorsement for structures rented to others, or a separate dwelling policy on the outbuilding, fills that gap and adds liability for the tenancy. Tell us about the unit before a tenant moves in, not after a claim.

Buildings of five or more units

Five units is where personal lines stop. An apartment building of that size is a commercial habitational account, usually placed on one package policy covering the structure, lost rents, liability for the premises and breakdown of boilers and other shared equipment. We place Connecticut buildings of five or more units with Vermont Mutual, Andover and Providence Mutual; our Connecticut apartment building insurance page explains what those carriers look at.

Seasonal, furnished and short-term rentals

Greenwich treats short stays as a zoning question. Since January 2022, a short-term residential rental, meaning fewer than 30 consecutive nights, has been allowed in the town’s residential zones only in space covered by a certificate of occupancy for a dwelling unit, for lodging only, with no parties, receptions, weddings, filming, photo shoots, corporate retreats or fundraisers. Bedrooms used by guests must meet the state building code’s emergency escape requirements, and accessory units and below-market units may not be rented short term (Greenwich Building Zone Regulations). A 2024 report by the legislature’s research office noted that Greenwich, unlike the other towns it reviewed, does not require a permit (OLR report 2024-R-0044).

Insurance follows the length of the stay. A one-year lease to a family is a standard landlord risk. A furnished summer rental of a few months puts your own furniture, art and linens in the tenant’s hands, so contents coverage and an inventory matter. Week-to-week guests look more like a small inn, and most homeowners and dwelling forms are not written for that use. If your own home will be rented while you are away, ask before you sign the lease, because some homeowners policies allow occasional rental and others do not.

The gaps between tenants deserve attention too. After roughly two months with no one living there, many dwelling policies stop paying for vandalism, broken glass and certain water damage. Keep the heat on, shut the water off when you can, and have someone walk through the house every week.

Owning through an LLC, a trust or an estate

Many Greenwich rentals are not titled to a person. An LLC, a revocable trust or the estate of a parent often holds the deed, and the policy has to follow the title. Name the LLC that owns the property, and usually its members or manager as well. For trust-owned property, the trustee is typically the named insured. Ask whether your personal umbrella reaches property owned by an LLC, since many umbrellas need an endorsement or a separate policy for that.

Estates raise their own issues. An inherited house can sit empty for months while it is cleared, listed or settled, and vacancy limits on the existing policy may already apply. The executor should tell the carrier about the death and the change in occupancy right away. If tenants are in place, Connecticut treats executors, trustees and other court-appointed receivers who collect rent as landlords for security deposit purposes, and a landlord who lives outside Connecticut must appoint the Secretary of the State as agent for service of legal papers (CGS 47a-21).

Liability, umbrella and your own home

Landlord liability claims usually begin with a fall on ice, a loose stair rail or a dog bite, and in Greenwich they can involve pools, docks and long private driveways as well. Carry a liability limit that matches the property, then add a personal umbrella that lists every rental. If your own house is a high-value home, Cincinnati and Chubb both write homes at any dwelling limit, and we compare them for the house you live in while placing the rentals with the carriers that fit them. Our Greenwich high-value home insurance page covers that side.

Flood risk for Greenwich rentals

The town’s section of the WestCOG hazard mitigation plan lists the problem spots. The Byram River between Route 1 and Comly Avenue floods the Pemberwick neighborhood; the plan notes a study with the state transportation department, under way since 2012, on replacing the Route 1 bridges at the state line. Greenwich Creek has flooded at East Putnam Avenue and Hillside Road. The southern reaches of Brothers Brook and the Mianus River Pond have wide floodplains and 18 repetitive loss properties, and the coastline from Greenwich Point and Old Greenwich to Cos Cob is low-lying. The plan also lists the Pemberwick and Rockwood Lake dams among the town’s high hazard dams.

Town staff told the planners that many owners carry no flood insurance or skip filing claims, so recorded losses understate the risk.

Flood coverage for landlords

New NFIP flood policies go through Selective. On a one- to four-family residential building, the NFIP building limit is $250,000, and as a landlord your contents coverage reaches only property you own, such as appliances and furnishings you supply. Rent you lose while the building is repaired is not covered by the NFIP Dwelling Form (FEMA Dwelling Form), and new policies generally wait 30 days before they take effect. Private and excess flood can raise the building limit and, on some policies, add lost rent. Our private markets are Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge. Check the property’s zone with the FEMA Flood Map Service Center and read our Greenwich and Westport shoreline flood insurance page.

Greenwich and Connecticut rules for landlords

• Fair Rent Commission. Greenwich’s commission, governed by a town ordinance the RTM adopted in March 2024, hears tenant complaints about excessive increases, new charges for utilities or services, and rents on units with serious, unsafe conditions. It can limit or phase in an increase, suspend rent until required repairs are done and order a landlord to stop retaliating. Rentals on a seasonal basis are outside its review (Fair Rent Commission; ordinance).
• Repairs and habitability. State law requires a landlord to follow building and housing codes, keep the premises fit to live in, keep common areas clean and safe, maintain heating, plumbing, electrical systems and elevators, and supply running water, hot water and reasonable heat (CGS 47a-7).
• Security deposits. Capped at two months’ rent (one month once a tenant reaches 62), held in escrow at a Connecticut financial institution and returned with interest within 21 days after the tenancy ends or 15 days after you receive a forwarding address, whichever is later (CGS 47a-21).
• Lead. Homes built before 1978 may contain lead paint, and many landlord policies limit or exclude lead claims. Ask how each carrier handles it and keep records of inspections and abatement.

A rent cut ordered over code conditions is not an insured loss; fair rental value coverage pays only after covered physical damage.

What underwriters ask about Greenwich rentals

• Title and occupancy. Who holds the deed, whether you or family live on site, lease length and any short-term or seasonal use.
• Systems. Roof age and type, electrical service and panel, heating fuel and age, water heaters, and supply lines.
• Accessory units. Town approval, the separate entrance and parking, and smoke and carbon monoxide alarms.
• Amenities. Pools, docks, hot tubs and trampolines, and how access is controlled.
• Water and flood. Mapped zone, any elevation certificate, units below grade, sump pumps and earlier water claims.
• Vacancy. How long the property sits empty between tenants and who checks on it.

Why an independent agency fits Greenwich landlords

A leased estate, a carriage-house apartment, a Byram two-family and an LLC-owned condo rarely belong with one carrier. We place each where it fits, keep the named insureds straight and put one umbrella over all of them.

Frequently asked questions

What policy does a Greenwich rental house need?

A house or condo you lease out and do not live in is usually written on a dwelling fire (landlord) policy, preferably the open-perils DP-3 form, with fair rental value and premises liability. A two- to four-family where you live in one unit can often go on a homeowners policy instead.

I rent out the apartment over my garage. Is my homeowners policy enough?

Not on its own. Standard homeowners forms generally exclude other structures rented to someone who is not a tenant of the main house, unless the building is used only as a private garage. An endorsement for structures rented to others, or a separate dwelling policy, closes that gap. Greenwich also requires the owner to live in either the main house or the accessory unit.

Can I rent my Greenwich house for a few weeks in summer?

Town zoning allows stays of under 30 nights in a dwelling unit, for lodging only, with no parties, weddings, filming or similar events, and never in an accessory unit. Most homeowners and dwelling policies are not written for short-term guests, so tell us before you list it and we will look for coverage written for that use.

My rental is owned by an LLC. Whose name goes on the policy?

The policy should name the LLC that holds title, and usually you as a member or manager as well. A mismatch between the deed and the policy can complicate a claim. Check that your umbrella extends to property the LLC owns; many personal umbrellas do not without an endorsement.

Does the NFIP pay lost rent after a flood?

No. The NFIP Dwelling Form does not cover loss of rental income. Some private flood policies offer it as an option, which we compare for owners who rely on the rent.

Does the Greenwich Fair Rent Commission apply to my rental?

It hears complaints about excessive rent increases, newly added charges for utilities or services, and rents on units with serious code problems. Under the town ordinance, accommodations rented on a seasonal basis are outside its review.

What do you need to quote my rental?

The address, how the deed is titled, the number of units, the year built and update years for the roof, wiring, heating and plumbing, whether anyone in the owner’s family lives there, lease terms, and five years of claims. Call (603) 431-4020 or use the form here. Request a quote. There’s no obligation to buy.
