Can a duplex or fourplex be insured on a landlord policy?

Often yes. Two-to-four-unit properties can usually be written on a landlord or dwelling-fire policy, the same family of coverage as a single rental, though with higher limits to reflect more units and more rent. At five units and above, the property generally moves into commercial property coverage. We confirm which form fits and make sure the limits reflect the full building.

How does loss of rents work on a multi-unit property?

It should cover the rental income from all the units, not just one. If a covered loss takes part or all of the building offline, loss-of-rents coverage replaces the income while it is repaired, for the period of restoration. Owners often size it to a single unit's rent or an outdated figure, so it is worth confirming it reflects the full current rent roll across every unit.

Who is liable for common areas in a small multifamily building?

Generally the owner. Shared entries, stairs, hallways, and yards sit outside any single tenant's unit, so an injury there is the owner's exposure. With more units and more foot traffic, that liability grows, which is why liability limits and an umbrella matter more on a fourplex than on a single rental. We size the liability to the building's actual use.

When does my multifamily property need commercial coverage?

Typically at five units and above, where the property moves from personal-lines landlord coverage into a commercial property program with commercial valuation, business income, and often commercial financing requirements. Four units and under usually stays on a landlord form. If you are buying or building toward five-plus units, it is worth planning the coverage shift before you close.

Small Multifamily Insurance (2-4 Units)

Coverage for duplexes through fourplexes.

A two-to-four-unit property is still usually personal-lines landlord territory, but more units change the math. More tenants mean more liability and more rent at stake, common areas become your exposure, and at five units the coverage shifts into commercial.

Small multifamily, duplexes through fourplexes, can often be written on a landlord or dwelling-fire policy, but the risk profile is heavier than a single rental. Each added unit adds tenants, liability, and rental income to protect, and shared entries, stairs, and yards become common-area exposure the owner carries.

The risk pattern

More units mean a larger and more frequent liability exposure, a slip on a shared stair, an injury in a common area, and more rent at risk if a covered loss takes units offline. Loss of rents has to cover the income from every unit, not one. And the more units, the more a single fire or water loss can displace multiple tenants at once.

What to prioritize

Loss of rents sized to the full rent roll, liability sized to the combined foot traffic with an umbrella over it, and clear coverage on the common areas. Confirm the policy form still fits, four units is usually still personal-lines landlord territory, but the building should be valued to rebuild all of it. If you own it in an entity, the policy names the entity.

How we handle it

We confirm the right form for the unit count, size loss of rents to the full rent roll, set liability and umbrella to the combined exposure, make sure common areas are covered, and confirm the valuation and the named insured. As you approach five units, we flag the shift toward a commercial program.
