If you own a home and plan to lease out a portion of your property, such as a basement suite, a spare bedroom, or an accessory dwelling unit (ADU), you may wonder if you need to carry both homeowners and renters insurance. While both options provide critical property and liability protection, they are engineered for distinct legal roles and cannot overlap for the same individual on a single property.

What Is Renters Insurance vs. Homeowners Insurance?

Homeowners insurance (typically an HO-3 policy) covers the physical structure of your home, your personal belongings, and certain liability, such as if someone is injured on your property. If a storm damages your roof or a pipe bursts in your basement, this is the policy that pays.

Renters insurance (an HO-4 policy) is built for someone renting a home or apartment from someone else. It doesn't cover the building itself, only the renter's belongings and their liability. It helps replace items lost to fire or theft, and covers the renter if they accidentally damage someone else's property or cause an injury.

Can You Have Both Policies on the Same Home?

Typically, no, not for the same purpose. Homeowners insurance is for the person who owns the property; renters insurance is for the person renting it. If you own the home, your homeowners policy covers your needs. If you're renting, renters insurance is what you need.

That said, if you're a homeowner renting out part of your home, a separate unit, or an accessory dwelling unit (ADU), both policies exist at once, side by side: you carry homeowners insurance, your tenant carries renters insurance, and each covers what they're responsible for.

How the Two Policies Divide Coverage

When a homeowner rents out part of their home, it can seem like both types of insurance are needed within the same property. Each policy stays in its own lane, covering only what that person owns or is responsible for.

• Your homeowners policy covers: the house structure, your appliances, the roof and drywall, and your own liability.
• Your tenant's renters policy covers: their furniture, electronics, clothing, and their own liability.

A simple way to picture it: if a burst pipe floods a rented basement suite, your policy pays to fix the walls and floor, theirs pays to replace their furniture, TV, and clothes.

What to Keep in Mind When Renting Out Part of Your Home

‍For homeowners who want to lease out part of their home, there are a few things to keep in mind to ensure you’re fully protected:

• Add a landlord endorsement, or get a separate landlord policy. Standard homeowners policies assume only your immediate family lives there. You're required to notify your insurer once you take on a tenant; failing to do so can mean a denied claim if something happens. For most setups, a landlord endorsement (a "unit rented to others" rider) added to your existing policy is enough. For a fully detached unit, like a backyard ADU, you may need a separate landlord policy (DP-3).
• You can require renters' insurance in the lease. It's a common misconception that you can't you can include a clause requiring your tenant to carry an HO-4 policy with a set liability limit (commonly $100,000), and ask to be listed as an "Interested Party." This costs the tenant nothing, and the insurer will notify you if the policy lapses or gets cancelled.
• Set clear boundaries on shared spaces. If you share a laundry room or backyard, set clear guidelines. Your homeowners policy won't cover a tenant's belongings even in shared areas, so their renters policy still matters there.
• Get proof before move-in. Ask your tenant for a copy of their renters' insurance declaration page before they move in, confirming the policy is active.

Understanding what each policy actually covers makes it easier to protect your own property and set the right expectations with your tenant from day one, keeping both sides covered and clear on where responsibility lies.
