Does My Quadplex Need Commercial Insurance? A Guide to 1–4 Unit Rules

Many landlords are unsure whether a quadplex (four-unit property) requires commercial insurance or if standard landlord coverage is sufficient. The distinction matters because insurance requirements, coverage options, and premiums differ significantly between commercial and residential policies.

This guide explains the 1–4 unit insurance rules, when commercial insurance might apply, and how working with Wexford Insurance ensures your quadplex is properly protected.

1–4 Unit Rule Explained

Insurance and lending guidelines typically divide residential rental properties into two categories:

• 1–4 Units: Considered residential rental properties

• 5+ Units: Classified as commercial real estate

Because a quadplex has four units, it falls into the 1–4 unit residential category. This classification allows landlords to purchase residential landlord or multi-unit property insurance rather than more expensive commercial policies.

💡 Key takeaway: Most quadplexes do not require commercial insurance simply because they have multiple units.

When Commercial Insurance Might Be Required

Even though quadplexes are generally considered residential, there are scenarios where commercial insurance may be necessary:

• Mixed-use buildings: If the property contains retail, office, or other non-residential units

• High liability exposure: Multiple rental units with shared amenities, high traffic, or public spaces

• Lender requirements: Certain financing programs may request commercial policies for 1–4 units with unusual risk profiles

• Short-term rentals: Properties listed on platforms like Airbnb may require commercial or hybrid coverage (Find Out More)

For standard four-unit rental housing, quadplex landlord insurance is usually sufficient.

Why Residential Landlord Insurance Is Appropriate for Quadplexes

Residential landlord insurance covers:

• Property/Dwelling Coverage: Protects the structure from fire, storms, and vandalism

• Liability Coverage: Protects landlords from tenant, guest, or contractor injuries

• Loss-of-Rental Income: Covers lost rent if the property becomes temporarily uninhabitable

• Optional Endorsements: Flood, earthquake, umbrella liability, and equipment/appliance coverage

This coverage is designed for 1–4 unit properties and is generally more cost-effective than commercial insurance.

Risks of Using the Wrong Policy

Using homeowners insurance or the wrong type of commercial insurance can create significant gaps:

• Homeowners insurance: Often excludes rental activity

• Commercial insurance: More expensive and may include unnecessary coverage

• Coverage gaps: Can result in denied claims, liability exposure, or lender issues
