Airbnb Co-Host Agreement: What to Put in Writing Before You Split Responsibilities

A co-host arrangement can work well. Two people share the workload, a property gets better coverage, and a host gets time back. But when something goes wrong with a guest, the first question that comes up is almost never about the guest. It is about who was supposed to handle it.

Without a written co-host agreement, that question does not have a clean answer. This article covers what to include, who owns which pieces of the paper trail, and how the agreement connects to your ability to document and pursue a claim when a guest breaks a rule.

This is not legal advice. For questions about enforceability in your jurisdiction, consult a local attorney.

What an Airbnb Co-Host Agreement Actually Is (and Isn't)

Airbnb's platform allows a primary host to add co-hosts to a listing. The platform handles the technical access side of that relationship. It does not govern how responsibilities are divided between the two of you.

A co-host agreement is a private document between the primary host and the co-host. It spells out who does what, how payouts are split, and what happens when something goes sideways. Airbnb does not require it, review it, or enforce it.

The agreement is not a lease. It is not a contract with the guest. It has nothing to do with what guests agree to. Think of it as your internal operating manual for the arrangement.

What it actually is: a written record of who owns which tasks, so that when a dispute comes up with a guest or between the two of you, there is something to refer back to.

Divide the Responsibilities Before You Divide the Payout

The most common mistake in co-host arrangements is agreeing on the payout split before agreeing on the work split. Those two decisions should happen in the same conversation, because the work is what makes the payout fair or unfair.

A useful way to approach this is to write down every recurring task and assign a clear owner. The list usually falls into a few categories:

Guest communication. Who sends the pre-arrival message? Who responds to questions during the stay? If a guest messages at midnight, who picks it up? This needs one named person per task, not "we both will."

Check-in and check-out. Who confirms check-in? Who handles the airbnb check-out instructions follow-up? Who does the post-checkout walkthrough?

Maintenance and turnover. Who coordinates cleaning? Who handles vacation rental turnover checklists and photos after each stay?

Incident response. Who calls the guest if there is a problem during the stay? Who contacts Airbnb support?

Write each task down with one name next to it. If you cannot agree on who owns a task, that is a signal to keep talking before the arrangement goes live.

Who Owns the Paper Trail?

The paper trail is not a side task. It is the foundation of any claim you might ever file. If the paper trail has a gap, the claim is weaker. If no one knows who was supposed to build it, the gap is almost guaranteed.

Your co-host agreement should name one person responsible for each of the following:

• Pre-stay property photos (timestamped, systematic)
• Post-stay property photos
• Guest communication logs
• Signed acknowledgment of house rules before check-in
• Filing claims within Airbnb's deadlines

That last item on the rule acknowledgment matters more than most hosts realize. A guest who breaks a no-smoking rule, brings an unauthorized pet, or damages the property is much easier to hold accountable when there is documented proof they saw and acknowledged the rules before arriving. PreArrive produces a timestamped evidence certificate when a guest reviews and signs the house rules before check-in. Whoever is responsible for the pre-arrival guest communication should be the same person responsible for making sure that step actually happens.

For a broader look at what to keep and for how long, see Airbnb Host Documentation: What to Keep and How Long. The co-host agreement should reference these documentation standards explicitly so both parties are building toward the same file.

What Happens When a Guest Breaks a Rule

This section is where most co-host arrangements fall apart. When a guest breaks a rule, there are several things that need to happen quickly and in the right order. If no one owns each step, steps get skipped.

Your agreement should spell out the incident response chain:

1. Who assesses the situation first. Is it whoever is on call that day? Is it always the primary host?
2. Who communicates with the guest. One voice. Not two. Mixed messages from two hosts create confusion and can undermine a claim.
3. Who documents the damage. Photos, videos, descriptions. See Vacation Rental Damage: Build a Paper Trail for what a solid documentation file looks like.
4. Who files with Airbnb. The primary host technically owns the listing and is usually the one who should file, but the co-host may have collected the evidence. Make sure the handoff is explicit.
5. Who follows up on the claim. Airbnb has filing deadlines. Someone needs to own the calendar.

If a guest broke a specific rule, the signed acknowledgment of those rules becomes part of your evidence file. When that acknowledgment exists and is timestamped, the conversation with Airbnb support shifts from "did the guest know?" to "here is documentation that they did." For more on what that file should contain, see Airbnb Damage Claim Evidence: Close the Gaps.

Fee Collection: Spell Out Who Does What

Extra fees are a common source of confusion in co-host arrangements. If the co-host is the one who notices an unauthorized pet, are they also the one who pursues the pet fee? If a guest checks out late, who sends the late checkout fee request?

Your agreement should cover:

• Which fees are in place (late checkout, extra guests, smoking, pets, early check-in)
• Who is authorized to pursue each fee
• How collected fees are split or whether they go entirely to one party

This is not just about money. It is about making sure fee requests go out consistently and are backed by documentation. A fee request that goes out without evidence is easy to dispute. One that references a signed acknowledgment of the relevant rule and includes timestamped photos is harder to ignore.

For the documentation side of specific fees, see Airbnb Late Checkout Fee: Set It, State It, Collect It and Airbnb Pet Fee: Set It, State It, and Back It Up.

Before the First Guest Arrives: A Shared Checklist

Before you take your first booking as a co-host team, go through this list together. Each item should have an owner and a process, not just a good intention.

• [ ] Co-host agreement is written and signed by both parties
• [ ] Responsibilities are assigned by name, not "we will figure it out"
• [ ] Payout split is documented and agreed to in writing
• [ ] House rules are finalized and consistent across all guest-facing channels
• [ ] Pre-stay photo documentation process is set up and assigned
• [ ] Guest pre-arrival acknowledgment process is in place (who sends it, when, what happens if a guest does not complete it before check-in)
• [ ] Incident response chain is written down and both parties have reviewed it
• [ ] Claim filing responsibilities and deadlines are understood by both parties
• [ ] A shared or accessible log for guest communications is set up

The acknowledgment step deserves extra attention. If the co-host is managing day-to-day guest communication, they are likely the one sending the pre-arrival message. That message should include the step where the guest reviews and signs the house rules. The timestamped certificate that comes from that process is part of the evidence file for the primary host's listing. Make sure the primary host has access to those records, not just the co-host.

A co-host arrangement built on clear written roles is more durable than one built on trust and goodwill alone. Trust is useful. A written agreement is what you hand to Airbnb support when a claim gets complicated.
