Here's how to detect cigarette smoke and smoking in a short-term rental: watch for the visible signs during turnovers and use a cigarette smoke detector that alerts you in real time when a guest lights up. Together, they give you both the early warning and the evidence you need to act before the smell sets in.
This is important because it doesn't matter how clearly you state it in your house rules, there’s still a risk that guests smoke in your short-term rental property, and by the time you find out, it's too late. A lasting smell, burn marks on the couch, and yellowing walls mean costly deep cleans and unprofitable downtime. With a specialized detector for cigarette smoke, you can be confident that your property is safe from smoke damage.

Here are some of the main reasons you want to prevent guests from smoking in your short-term rental:
Whether you run a short-term rental or lease a property long-term, the challenge is the same: you're not on-site, and smoke leaves its mark long after the guest or tenant has gone. Knowing how to detect smoking in a rental property comes down to two routes: spotting the signs after the fact, and catching it as it happens with a sensor.
Between stays, or during a routine inspection of a long-term rental, look for the physical tells. These are the signs a tenant is smoking even when they weren’t caught or nobody admits to it:
Visible signs tell you that smoking happened, but they don't tell you when, or which guest was responsible. For that, you need a record. And if the smell has already set in, an ozone machine can help remove the smoke smell before your next booking.
The reliable way to detect smoking is a cigarette smoke detector that monitors the air and alerts you the moment it identifies smoke. Unlike a fire and CO alarm, cigarette smoke detectors are built to specifically recognize smoking, and they send the alert to your phone instead of sounding a siren in an empty room.
Because the alert is timestamped, you get more than a heads-up. You get a record you can use if a guest or tenant disputes the smoking event.
Sometimes it's obvious someone has been smoking in your unit, while other times the signs are more subtle. But even if a guest doesn't leave clear evidence of having smoked in your property, the effects are nonetheless detrimental. After all, if every guest did the same, you'd end up with a persistent smell along with yellowing walls and ceilings.
Here's how to detect indoor smoking in your vacation rentals:

Simply stating you have a no-smoking policy in your listing isn't always enough to protect your vacation rentals and business from the lasting effects of cigarette smoke. Here are some proactive strategies you can implement to minimize the risk of guests smoking in your units.
Being proactive is the best way to prevent guests from smoking at your properties. When a guest makes a reservation request, be sure to look at the reviews other hosts have left them and see if there is any mention of smoking incidents.
If you're particularly worried, you can even send potential guests a message reminding them you have a no-smoking policy and asking if that will be an issue for them.
A mention of your no-smoking policy in your listing is a start, but be sure to educate your guests about your rules and guidelines after they book. You can do this by including your no-smoking policy in your house rules and sharing it with guests before they check in.
Additionally, you can send guests a pre-stay message that serves as a friendly reminder of the most important guidelines they should follow during their stay, including the fact that smoking in your unit is prohibited. Plus, be sure to include clear signage at your property that smoking indoors is prohibited.
If you rent to smokers, they're going to look for a place to light up. So while you can discourage smoking at your property, and even enforce penalties like fines and additional cleaning fees for guests who smoke inside, it's a good idea to provide an outdoor smoking area.
This doesn't have to be a big investment, a simple small table with chairs, an ashtray and trash can will suffice. That way, you give guests who do smoke a designated place to do it, and they'll be less inclined to break your house rules and smoke indoors.
While the three previous strategies can play a big role in preventing smoking at your short-term rentals, they can't guarantee guests will abide by your rules and not smoke in your units. That's why you need to have solutions in place that alert you to smoking incidents.
Cigarette smoke detection technology alerts you if a guest is smoking in your unit, helping you address the issue in real-time. Here's how Minut's smart home technology for vacation rentals does just that.
Using a specialized device like the Minut sensor is the best way to be certain guests are smoking in your unit and address the problem as soon as it happens. You can do so by following these four simple steps.
Airbnb requires you to disclose the use of certain devices, like noise monitors, in your listing. We suggest you inform guests you're using a cigarette smoke detection sensor in your unit for the sake of transparency.
Here's an example of what you could say in your listing:
"This home is equipped with a privacy-safe device that monitors the environment inside the property (including noise levels, temperature, motion, and cigarette smoke) to ensure guests have a pleasant stay and our neighbors are not disturbed."
Be sure to clearly explain that this is different from a traditional fire smoke and CO detection device. Not only will potential guests appreciate your honesty, but knowing there's a device in your unit that will detect cigarette smoke deters smokers from booking with you.
Also underline that the device respects guest privacy and is just in place as a safeguard for the property.
Installing the Minut M3 sensor takes just a few minutes. We outline the steps in detail in this help article, but here's a quick breakdown of what you need to do:
At this point, you can configure your noise threshold, as well as cigarette detection, which takes us to our next step.

To ensure your Minut sensor is detecting cigarette smoke in your unit, you need to enable the feature within the Minut app. Just open the app and turn smoking detection on.

Minut notifies you when the sensor detects cigarette smoke within your property. That means you can address the issue quickly and minimize any risk.
Minut also keeps historical logs of all smoking data, so you're covered in the case of a dispute with a guest who claims they weren't smoking and doesn't want to pay your additional cleaning fee.
You can access your log of smoking events within the Minut dashboard, meaning you can also track which guests you had problems with in the past so you can be sure not to rent to them again in the future.

What was supposed to be an easy long weekend rental could end up with you having to pay for extra deep cleans and buy an ozone generator to remove the lasting smell of cigarette smoke. For property owners and managers, the risk of guests smoking in your units is an ongoing source of stress.
However, with proactive steps to prevent guests from smoking and measures to detect it when it happens, you can minimize this risk and start hosting with confidence. That's why you need a specialized cigarette smoke detection device.
Minut gives you real-time alerts about smoking events, as well as a log of past incidents, and it won't confuse burnt popcorn for a guest smoking.
Best of all, Minut offers a suite of features to protect your property, like noise monitoring, occupancy monitoring, and motion detection. By using Minut, you'll have visibility across your portfolio and a timestamped record you can use whenever a guest, neighbor, or regulator disputes what happened.

Some of the telltale signs of someone smoking in your vacation rental are the smell and visual evidence, including cigarette ends, ashtrays, and smoke stains on the walls and ceilings. But the only guaranteed way to prove someone smoked in your unit is by using a specialized cigarette smoke detector.
There are a few cigarette smoke detectors for vacation rentals on the market. Minut can detect cigarette smoke, will alert you if someone is smoking in your unit, and keeps a record of all your smoking incidents, as well as offering other features that help you protect your vacation rental, like noise and occupancy monitoring.
There are no legal restrictions on smoking in vacation rentals. However, as a property manager or host, you have the right to set smoking restrictions for your properties and monitor smoking activity. That way, you can prove when guests have been smoking, and take action to protect your STR business.
A cigarette smoke detector monitors the air in your property and alerts you when it detects guests smoking. Unlike a fire alarm, it's designed to detect smoking specifically and notify you on your phone rather than sound a siren. With Minut, each detection is logged with a timestamp, giving you a record you can share with Airbnb, a neighbor, or a tenant in a dispute.
