Apartment Building Insurance in Stamford, CT

By Jonathan Merwin, Founder and CEO, Licensed Insurance Advisor

Stamford isn’t a typical Connecticut rental market. Drive from Glenbrook to the South End and you pass two- and three-families on side streets, brick and frame walk-ups from the 1950s and 1960s, garden-apartment complexes along the parkway corridors and, closer to the train station and Harbor Point, towers with hundreds of units. The building you own decides which kind of policy it needs, which carriers will look at it and which risks matter most, from a frozen pipe in a garden-level unit to a storm tide coming up Stamford Harbor.

This page is for owners of Stamford apartment buildings: the two- to four-family you live in or rent out, and the five-to-fifty-unit building that has crossed into commercial habitational coverage. If you own one or two rental houses or condos, our Stamford landlord insurance page is the better fit.

Stamford’s rental stock, by building size

The Census Bureau’s 2024 American Community Survey counts about 58,200 housing units in Stamford. Roughly 25,700 of them, or 44%, are in buildings with five or more units. That’s a much bigger share than in most Connecticut cities, and it’s driven by the large downtown and Harbor Point buildings: about 16,600 units sit in buildings of 50 or more. The rest are in buildings of five to 49 units (B25024).

Small multi-families are a smaller slice: about 2,300 units in two-family houses and 3,900 in three- and four-unit buildings, many on the West Side, the East Side, Glenbrook and Springdale.

Age matters as much as size. About 32,400 of Stamford’s housing units, or 56%, were built before 1980, and about 8,500 were built in 1939 or earlier. About 8,800 date from 2010 or later (B25034), so a 1962 walk-up and a 2018 mid-rise on the same street get underwritten very differently.

Two- to four-family buildings in Stamford

If you live in one of the units

An owner who lives in a two-, three- or four-family can often insure the whole building on a homeowners form. That covers the structure, your own belongings and your personal liability, and it can include loss of rents on the units you rent out. It’s worth comparing against a dwelling policy.

If you don’t live there

A non-owner-occupied two- to four-family goes on a dwelling fire policy. We usually suggest the open-perils DP-3 form with replacement cost on the building, fair rental value for every unit and premises liability. For one- to four-unit Stamford buildings we compare Vermont Mutual, Andover, Liberty Mutual, Hanover, Providence Mutual and Foremost. Vermont Mutual can also write multi-family rentals of one to four units on a BOP when that structure fits the owner better.

If the building is in an LLC, the LLC should be the named insured and should appear on any umbrella. Underwriters also want the legal unit count, so talk to us first if an attic or basement unit was added.

Five or more units: commercial habitational coverage

Once a building reaches five units, most carriers treat it as a commercial habitational risk. For Connecticut apartment buildings of five or more units, we place coverage with Vermont Mutual, Andover and Providence Mutual. Our Connecticut apartment building insurance guide covers what those carriers look for in detail.

A habitational package or BOP usually bundles:

• Building coverage at replacement cost, with the limit set to what it would cost to rebuild, not the purchase price or the assessment.
• Business income / loss of rents, sized to your full rent roll and to a realistic rebuild time. A fire in a 20-unit building can keep tenants out for many months.
• General liability for common areas, stairs, lots and walks.
• Equipment breakdown for boilers, elevators and electrical gear, where the carrier offers it.
• Building ordinance or law coverage (more on that below).
• Common-area contents such as laundry and maintenance equipment.

Underwriters ask about construction type, sprinklers and alarms, roof and boiler age, electrical and plumbing updates, garden-level units, any ground-floor retail, vacancy and five years of losses.

If the building is a condominium rather than an apartment building, the association needs a master policy instead. See Connecticut condo association insurance, and for unit owners, Stamford condo insurance.

In Stamford, the size of the building decides the form, but where it sits relative to the hurricane barrier often decides the flood plan.

Stamford’s licensing and apartment certificate rules

Stamford regulates rental buildings through its Department of Health. According to the city’s permits and licenses page:

• Multiple Family Dwelling License. Chapter 146, Section 34 of the city code requires owners or operators of multiple-family dwellings to hold an annual license from the Department of Health. Licenses expire December 31, and a new license is required each January 1.
• Certificate of Apartment Occupancy (CAO). Under Chapter 146, Section 33, once a building with four or more apartments is 15 years old, each apartment must be certified as fit for occupancy every time it’s vacated. The city lists the CAO inspection fee as $75.
• No certificate, no rent. The city says rent isn’t recoverable for an apartment rented without a required CAO, and that renting one without it is illegal.

None of that is insurance, but it overlaps. After a fire or water loss, the time it takes to get units re-inspected and certified is part of your loss of rents period, so size that coverage with inspections in mind.

Stamford also has a Fair Rent Program, run through its Social Services Commission, which investigates complaints about excessive rent increases or reduced housing services (City of Stamford). Insurance doesn’t pay for upkeep, and claims from wear and tear are excluded, so keeping repairs current protects you on both fronts.

Flood: the hurricane barrier, the South End and the Rippowam

The U.S. Army Corps of Engineers built the Stamford Hurricane Protection Barrier between 1965 and 1969, after the 1938 hurricane and Hurricane Carol in 1954. It combines a dike across the East Branch of Stamford Harbor, a wall and dike on the West Branch and the Westcott Cove dike (USACE). During Sandy in October 2012 the water at the barrier reached 11.1 feet, the highest on the Corps’ record (USACE barrier peaks).

The city’s 2021 hazard mitigation annex says portions of Harbor Point and the South End are mapped as having reduced flood risk because of the levee, and it names Shippan Point, Waterside and the East Side around Cummings Park as low-lying coastal areas exposed to nuisance and storm surge flooding. It counts 102 repetitive loss properties in Stamford, 68 of them in the coastal zone and 12 along the Rippowam River (WestCOG Stamford annex).

For apartment owners that means three different situations:

• Behind the barrier (much of the South End and Harbor Point): reduced surge risk, not zero. Rain, high groundwater and drainage backups can still flood garages and mechanical rooms below grade.
• Outside the barrier (Shippan Point and other shoreline in front of the dikes): open-water surge exposure, often in mapped high-risk zones where a lender will require flood coverage.
• Inland, along the Rippowam and smaller brooks: river and flash flooding can reach buildings that never see salt water.

NFIP and private flood for Stamford buildings

Standard landlord, homeowners and habitational policies exclude flood. New NFIP policies go through Selective. A new NFIP policy usually takes effect after a 30-day waiting period, with some exceptions, such as coverage required by a lender at closing, so don’t wait for a storm in the forecast. NFIP building limits are capped by building type: $250,000 for a one- to four-family residential building and $500,000 for a residential building of five or more units (FloodSmart). In Stamford, rebuild costs for an apartment building can be well above those caps.

That’s where private flood comes in. We can compare private flood carriers including Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge. Some offer higher building limits, shorter waiting periods or loss of rents coverage, which the NFIP doesn’t provide. Look up the address on the FEMA Flood Map Service Center or our flood zone check, and see Stamford flood insurance and Fairfield County flood insurance for more.

Building ordinance or law in Stamford

When an older building is badly damaged, the rebuild has to meet today’s building, fire and electrical codes. A standard policy pays to repair what was there; it may not pay for the upgrades. Ordinance or law coverage usually has three parts: the value of an undamaged portion that has to be torn down, the cost of demolishing it and the extra cost to build to current code.

It matters in Stamford because more than half the housing predates 1980, and because a building in a flood zone that is substantially damaged may have to be brought into compliance with floodplain rules, which can mean elevating or flood-proofing. NFIP flood policies include Increased Cost of Compliance coverage, up to $30,000, for some of that work (FEMA). It rarely covers the whole cost on a multi-unit building.

Liability, umbrella and tenants

Apartment buildings create more liability exposure than houses: shared stairs, laundry rooms, parking areas, snow and ice on walks, and more people coming and going. On a one- to four-family owned personally, a personal umbrella is the usual way to raise limits. On a commercial package, we’ll review the package’s liability limit and how any umbrella or excess coverage would sit over it.

Your policy doesn’t cover tenants’ belongings. Requiring renters insurance in the lease protects them, and their liability coverage can respond when a tenant causes a fire or a leak.
