On a renters insurance policy, an interested party (also called an additional interest) is a person or company, usually your landlord, that the insurer will notify in writing if it cancels or doesn’t renew your policy; an interested party gets no coverage. An additional insured is added to the policy’s definition of “insured,” so it gets part of the policy’s protection, typically liability coverage tied to your home, and shares your limit.
Key takeaways
- An interested party on renters insurance receives notice, not coverage: a typical “Additional Interest” endorsement (Auto Club form CO 04 10, July 2005 edition, built on Insurance Services Office wording) says only that the named party “will be notified in writing” if the insurer decides to cancel or not renew.
- An additional insured on a residential policy is covered by it: the ISO “Additional Insured – Residence Premises” endorsement (HO 04 41, 1991 edition) adds the named person or organization to the definition of “insured” for personal liability and medical payments to others with respect to the residence premises.
- An additional insured shares your liability limit: the standard ISO renters form (HO 00 04, 2000 edition) says the personal liability limit “is the same regardless of the number of ‘insureds’.”
- In Oregon, a landlord may require a tenant to name the landlord as an interested party on a renters policy but may not require additional insured status, and any required liability coverage is capped at $100,000 per occurrence or the customary local amount, whichever is greater (ORS 90.222, 2025 edition).
- If your lease asks for either status, give your insurer the exact wording and the landlord’s legal name and address, then send the landlord your updated declarations page as proof.
What is an interested party on renters insurance?
An interested party is someone outside your household, most often a landlord or property manager, whose name the insurer adds to your renters policy so it can tell them if the policy ends. Insurance forms also call it an “additional interest.”
The wording is short. In the Auto Club “Additional Interest – Residence Premises” endorsement (form CO 04 10, July 2005 edition, which carries an Insurance Services Office 1990 copyright), the named person or organization “also has an interest in the residence premises,” and if the insurer decides to cancel or not renew the policy, that party “will be notified in writing.” The endorsement gives the party no coverage, and the form states no number of days for the notice.
Because an interested party isn’t an “insured,” your policy doesn’t pay the landlord’s own losses or defend the landlord in a lawsuit. Your coverage stays exactly what it was.
Read your lease’s exact wording: “interested party,” “additional interest” and “additional insured” are different requests. An interested party only gets told when your renters insurance ends, while an additional insured is protected by part of it.
What is an additional insured?
An additional insured is a person or organization added to the policy’s definition of “insured,” which means the policy can protect them, not just notify them.
On a standard renters policy, only certain people are insureds: you, residents of your household who are your relatives or are under 21 and in the care of one of you, and certain full-time students who lived with you before leaving for school (ISO HO 00 04 10 00). A landlord isn’t on that list. An endorsement changes that. The ISO “Additional Insured – Residence Premises” endorsement (HO 04 41 04 91) and Auto Club’s later version (CO 04 41, July 2005 edition) add the named party as an insured for:
- Coverage E, personal liability, and Coverage F, medical payments to others, with respect to the residence premises (the Auto Club version excludes injury to the additional insured’s own employees on the job);
- Coverages A and B, the dwelling and other structures. Those parts are written for homeowners policies; a renters (HO-4) policy has no dwelling coverage, so for a renter the practical effect is mainly liability.
Both endorsements also say the named party “will be notified in writing” if the insurer cancels or doesn’t renew, so an additional insured gets the same notice an interested party does, plus coverage.
What is the difference between an interested party and an additional insured?
The difference is coverage: an interested party only gets told when your renters insurance ends, while an additional insured is protected by part of it.
| Question | Interested party (additional interest) | Additional insured |
|---|---|---|
| Gets notice if the insurer cancels or doesn’t renew? | Yes, in writing (Auto Club CO 04 10, 2005) | Yes, in writing (ISO HO 04 41, 1991; Auto Club CO 04 41, 2005) |
| Covered by your policy? | No | Yes, for the parts the endorsement names (on a residential policy: personal liability and medical payments to others for the residence premises) |
| Can the policy defend them in a lawsuit? | No | Yes, within the liability coverage extended to them |
| Uses up your liability limit? | No | It can: the Coverage E limit “is the same regardless of the number of ‘insureds’” (ISO HO 00 04, 2000 edition) |
| What a landlord gets out of it | Early warning that the tenant’s coverage has lapsed | Protection under the tenant’s liability coverage |
| Can a landlord require it in Oregon? | Yes (ORS 90.222(4), 2025 edition) | No (ORS 90.222(7), 2025 edition) |
The forms quoted here are standard ISO wording and one insurer’s version of it; your insurer’s endorsement may be worded differently, so read the one on your declarations page.
Why do landlords ask to be listed as an interested party?
Landlords ask to be listed as an interested party so they find out if a tenant’s required renters insurance is canceled or not renewed, without having to chase the tenant for proof every month.
Oregon’s statute spells out the purpose. A landlord there may require documentation that the tenant has named the landlord as an interested party, which authorizes the insurer to notify the landlord of three events: cancellation or nonrenewal of the policy, a reduction in coverage, and removal of the landlord as an interested party (ORS 90.222(4)(a), 2025 edition). The same section lets the landlord ask for periodic proof that coverage is in force.
Why do landlords want a tenant insured at all? A tenant’s liability coverage can respond to some damage the tenant causes, such as a kitchen fire (the renters form’s exclusion for property rented to you has an exception for fire, smoke and explosion), and the landlord’s own policy doesn’t cover tenants’ belongings. More on both: does renters insurance cover damage to my rental unit? and does my landlord’s insurance cover my stuff?
Can my landlord require me to add them as an additional insured?
It depends on your state and your lease. Oregon bars it outright; most states’ landlord-tenant laws don’t address the question, so the lease governs.
Oregon: interested party yes, additional insured no
Oregon is the clearest example found. Under ORS 90.222 (2025 edition), a landlord who requires renters liability insurance:
- may require proof that the tenant named the landlord as an interested party;
- may not require the tenant to name the landlord as an additional insured or give the landlord “any special status” other than interested party, may not require a particular insurer, and may not require the tenant to waive the insurer’s right of subrogation;
- may not require more than $100,000 of liability coverage per occurrence, or the customary amount for similar rentals in the same market, whichever is greater;
- may not require the insurance at all if the household income is at or below 50% of the area median income, or if the unit is subsidized with public funds (tenant-based Housing Choice Vouchers don’t count as a subsidy for this rule).
Oregon has a matching rule for manufactured dwelling parks: ORS 90.527 (2025 edition) lets the park landlord require interested-party status and bars requiring additional insured status.
Virginia: proof of coverage, no rule on either status
Virginia’s Code § 55.1-1206 lets a landlord require renters insurance as a condition of tenancy, and a tenant who buys a separate policy must give the landlord written proof and keep coverage in force for the whole lease. The section doesn’t mention interested parties or additional insureds; a policy the landlord buys for the tenant must cover the tenant as an insured.

Does naming my landlord give them a claim on my policy?
Naming your landlord as an interested party doesn’t give them a claim on your renters insurance; it only gets them a notice. Naming your landlord as an additional insured can, because the policy then covers them for the parts the endorsement lists.
Either way, a landlord who is a third party can still make a claim against your liability coverage for damage you’re legally responsible for, the same as anyone else you injure or whose property you damage. Oregon limits this for landlords who require the insurance: the landlord may claim only for damage the tenant is legally liable for (not ordinary wear and tear, acts of God or the landlord’s own conduct), the claim must exceed the security deposit, and the landlord must give the tenant a copy (ORS 90.222, 2025 edition).

How do I add my landlord as an interested party?
To add your landlord as an interested party, ask your insurer or agent to add the landlord’s name and mailing address to your renters policy, then send the landlord the updated proof.
- Read the lease’s exact wording: “interested party,” “additional interest” and “additional insured” are different requests.
- Get the landlord’s or management company’s legal name and the address it wants notices sent to.
- Ask your insurer to add it, and ask whether the change affects your price or coverage.
- Download the updated declarations page showing the landlord and send it as proof (step-by-step: how to get renters insurance).
- If you later switch insurers, add the landlord to the new policy before the old one ends, since the old insurer may send the landlord a cancellation notice (how to cancel without a gap).
