How to write Airbnb Additional Rules that actually hold up

The Additional Rules field on an Airbnb listing is real estate most hosts use poorly. It's the box at the bottom of the House Rules section — past the standard toggles, past "suitable for children" and the pet question, in the place where you can type whatever you want. Most hosts type the equivalent of a welcome card: "Please be respectful of the space. No smoking. Thanks!"

That kind of writing is fine if its only job is to set tone. It's not fine if its job is to be the disclosure half of a Resolution Center case six weeks from now, when a guest left burn marks on the patio and you're trying to put a fee in front of them. In that second case, what's in Additional Rules has to be specific enough that a reviewer can read it and agree the guest was on notice of the fee, the condition, and the amount. "No smoking" without anything else does some of that work. It doesn't do all of it.

This post is about the format that does all of it. It assumes you already understand the broader framing: Airbnb's Resolution Center weighs evidence at its discretion, and a fee that wasn't disclosed in the listing doesn't really exist for these purposes. If you want the full mechanic, the Resolution Center post covers it. This post is one level down: what to actually type.

The shape a useful rule has

A useful Additional Rules entry has four parts, and they need to be on the page in a form a stranger can find quickly:

1. The behavior or condition. What is or isn't allowed, stated concretely.
2. The number that defines it. Occupancy is a number, not "the limit." Quiet hours are 10 PM to 8 AM, not "after dark." Late checkout is an hour, not "later than expected."
3. The fee that attaches, with a unit. $500 per incident. $100 per guest per night. $75 per hour. Not "a fee" and not "a fine."
4. The trigger. What you must observe to assess the fee — a count, a time, a stain, a complaint logged with the city.

Each of those parts is easy to write and easy to forget. The most common omission is the unit — hosts write "smoking fee: $500" and don't specify whether that's per occurrence, per night, per cleaning visit, or per guest. Without the unit a fee can't really be charged, because both the host and the guest can disagree about what $500 attaches to.

A working example for smoking:

No smoking, vaping, or cannabis use anywhere on the property, including the porch and yard. If any of the above is observed by the cleaning team, the smoking remediation fee is $500 per incident, charged once per stay.

Compare that to "no smoking, $500 fee." Both communicate the same idea to a friendly reader. Only one of them survives being pointed at by a Resolution Center reviewer.

What the disclosure half is and isn't

Worth being explicit. The Additional Rules block is the disclosure leg of a two-leg requirement. The other leg is acknowledgment — what specific guest agreed, in writing, before this specific stay, to be charged this specific amount under this specific condition.

The disclosure leg is necessary and never sufficient. A perfect Additional Rules block won't help if you can't show the guest acknowledged it. Acknowledgment is what tools like PreArrive produce — a per-reservation, per-guest, signed record. The disclosure block on the listing is the public-facing half; the acknowledgment is the private file.

The reason to take both seriously, and not just the acknowledgment, is that the disclosure half is what Airbnb's reviewer can verify without leaving Airbnb. They can pull up your listing and read the Additional Rules block. They can't see what's in your CRM or your email. If the listing block doesn't contain the fee, the rest of the case effectively starts in the wrong position.

The five rules most hosts get wrong

These are the ones I see worded loosely most often. Tighten these five and the rest tend to follow.

Occupancy. Write the number into the rule, not a pointer to it. "Maximum overnight occupancy is 6 guests, including children and infants. Day visitors permitted up to 9 total people on the property between 10 AM and 10 PM. Bookings made for fewer guests than will stay are a violation of this rule." Pair it with a per-guest-per-night extra-occupancy fee.

Quiet hours. State the hours and what's prohibited during them. "Quiet hours are 10:00 PM to 8:00 AM. Outdoor amplified sound (speakers, instruments, loud gatherings) is not permitted during quiet hours. After one warning, the disturbance fee is $250 per incident."

Smoking. State the substances, the geography, the detection method, and the fee unit. The working example above is the shape.

Parties and events. Be specific about both. "No parties, no events, no commercial photo or video shoots, and no gatherings of more than [the occupancy number] people. Unauthorized event fee: $1,500 per occurrence, charged in addition to any damage assessment." The "in addition to" phrase matters; otherwise a host who collects a damage charge sometimes can't also collect the event fee.

Late checkout. Tie it to the listed checkout time on Airbnb, not a separate time only in the Additional Rules. "Checkout is by 11:00 AM as posted on the listing. After 11:00 AM, the late-checkout fee is $75 per hour or any portion of an hour, capped at a single night of the rental rate."

The pattern across all five: a number anchors each rule, a unit anchors each fee, and a trigger anchors each charge.

A footnote on where fees belong

Not every fee belongs in the Additional Rules block. Mandatory fees — cleaning, pet, extra-guest pricing that applies to every stay — belong in Airbnb's structured pricing fields, where they roll into the total the guest sees at booking. Conditional fees that only apply if a rule is broken (smoking, parties, late checkout) belong in Additional Rules. Putting a mandatory fee only in Additional Rules will sometimes have it ignored at booking and disputed after.

If you've never thought about which fees go where, the fee-compliance KB article walks through the line.

A faster way to write this

The five-paragraph version of the rules block above is the right structure, but typing it from scratch for every property is slow. The Additional Rules generator takes a list of rules and fees and produces a paste-ready block in the format described in this post. Nothing about it leaves your browser — it's a template-renderer, not a service. The output is the same shape this post argues for: behavior, number, fee, unit, trigger.

If you'd rather hand-write it, the post is enough. If you want the disclosure half generated in 30 seconds so you can move on to the acknowledgment half, the generator is there.

Either way, the rule worth internalizing is the smaller one: a fee that isn't anchored to a number, a unit, and a trigger doesn't really exist in the Resolution Center sense, no matter how strongly the host feels it should. The Additional Rules block is the cheapest place to fix that — and it's the place most hosts haven't.
