1. Smell in your Apartment

One way to determine if a tenant smokes in your apartment is through the smell. If you can smell tobacco or marijuana in the apartment or in common areas like hallways or elevators, it could mean that the tenant is smoking. The smell of smoke can linger for a long time, especially if the tenant is a heavy smoker.

To verify your suspicion, you can also ask other tenants or neighbors if they have noticed the smell. You can also hire a professional to do an air quality test to see if there are any traces of smoke.

2. Yellow Stains on Walls, Ceilings, and Furnishings

Yellow stains on walls, ceilings, and furnishings can indicate that a tenant is smoking in your apartment. The nicotine and tar in cigarette smoke can leave behind yellowish-brown stains on surfaces, particularly in areas where smoke accumulates.

You can inspect the unit for walls, ceilings, curtains, blinds, or furniture discoloration. Check for stains around light fixtures, electrical outlets, or ventilation systems. 

If you notice these telltale signs, the tenant is likely smoking indoors. However, it is essential to ensure that other factors, such as mold, mildew, or water damage, do not cause the stains. If you have doubts, consider again hiring a professional to identify the source of the stains.

3. Ashes and Cigarette Butts

If you come across ashes and cigarette butts in your apartment, it can be a clear indication that a tenant is smoking indoors. Check the common areas like balconies, patios, and window sills for any signs of ash or discarded cigarette butts. If you see any evidence of smoking in these areas, the tenant is likely smoking inside the apartment.

You can also inspect the inside of the unit for any ashes or cigarette butts in ashtrays, trash cans, or on the floor. However, keep in mind that some tenants may smoke outside the apartment and discard their cigarette butts or ashes inside, so it is important to examine all areas thoroughly before making any assumptions.

4. Smoke Detectors

Smoke detectors can be a useful tool to determine if a tenant is smoking in your apartment. If the smoke detector is triggered frequently, it could indicate that the tenant is smoking inside the unit. Check the smoke detectors regularly and note any false alarms. You can also inspect the detectors for any signs of tampering or damage, such as disconnected or covered sensors.

Additionally, you can install smoke detectors with hidden cameras to monitor any suspicious activity. Keep in mind that other factors, such as cooking smoke or steam, can also result in false alarms, so it is crucial to conduct additional research before taking any action.

5. Reports From Neighbors

Reports from neighbors can help determine if a tenant is smoking in your apartment. If neighbors complain about the smell or other signs of smoking, it’s worth investigating. Speak to them to gather more information, but verify it before taking action.

6. Surveillance Cameras

Surveillance cameras can be an effective way to determine if a tenant is smoking in your apartment. Install cameras in common areas like hallways, entryways, and other places where smoke can be detected. You can also consider placing cameras inside the unit if there is evidence of smoking or suspicious behavior.

However, it is essential to inform tenants of the camera’s presence and obtain their consent if required by law. 

Also, ensure that the camera’s location and angle comply with privacy regulations. Review the footage regularly to check for any signs of smoking or other violations. But it’s important to use surveillance cameras in a way that doesn’t invade the privacy of tenants.

7. Unannounced Inspections

Unannounced inspections can be an effective way to determine if a tenant is smoking in your apartment. Make sure to include a clause in the lease agreement that permits you to inspect the property at reasonable times with proper notice. However, if there is an immediate health or safety concern, you can conduct an unannounced inspection to investigate.

During the inspection, check for any signs of smoking, such as ashtrays, cigarette butts, or smoke odors. You can also look for any damages caused by smoking, such as burn marks on furniture or carpets.

However, be respectful of the tenant’s privacy and do not inspect areas that are not covered in the lease agreement. Also, document the inspection and any evidence found to support any further action, if necessary.

8. Health Issues Among Other Tenants

If other tenants report smoking-related health issues, it can be a sign that a tenant is smoking in your apartment. Smoke can cause respiratory problems, allergies, and other health issues, which can affect other tenants in the building.

Check to see if other tenants have had the same problems and if the symptoms match how the tenant smokes. You could also talk to a doctor to find out if the symptoms are caused by smoking.

However, keep in mind that other factors, such as poor air quality or environmental factors, can contribute to health issues. Therefore, investigate further and gather more evidence before taking any action.

9. Expert Testimony

Expert testimony can be a valuable way to prove that a tenant is smoking in your apartment. You can hire a professional to inspect the unit and identify any signs of smoking, such as smoke residue, nicotine stains, or cigarette butts.

They can also test the air quality to see if any harmful particles come from smoking. The expert can provide a detailed report and testify in court if necessary.

However, hiring a reputable expert with relevant qualifications and experience is vital. Also, ensure you comply with legal procedures and obtain the necessary approvals before hiring an expert.

10. Tenant Admission

Tenant admission can be a straightforward way to prove that a tenant smokes in your apartment. You can ask the tenant if they smoke inside the unit and document their response. If the tenant admits to smoking, it can serve as solid evidence in case of any legal proceedings.

However, remember that some tenants may deny smoking or lie about it, so it is essential to gather additional evidence to support your case. Also, ensure that you follow proper procedures and regulations before taking any action based on a tenant’s admission.

Can a Landlord Evict a Tenant for Smoking?

A landlord can potentially evict a tenant for smoking, but it depends on the terms of the lease agreement and local laws. If the lease agreement includes a no-smoking policy, the landlord can enforce it and terminate the lease if the tenant violates it.

However, the landlord must follow the proper eviction procedures and provide sufficient evidence of smoking in the unit. In some areas, local laws may require landlords to provide a warning or notice before evicting a tenant for smoking.

Moreover, the landlord may need to prove that smoking is a violation of the lease agreement and has caused harm to other tenants or the property. Therefore, it is crucial to consult with a legal expert and follow the appropriate legal procedures before evicting a tenant for smoking.


As a landlord, ensuring that your rental property is free from smoking can be challenging but is essential for maintaining a clean and safe environment for your tenants. You should hopefully now know how to prove a tenant is smoking in your apartment.

These include looking for yellow stains on walls and furniture, looking for ashes and cigarette butts, using smoke detectors and surveillance cameras, doing unannounced inspections, listening to reports from neighbors, getting expert testimony, and getting the tenant to admit to smoking. 

To avoid these problems in the future, you could write a tenants rules and regulations document which states your tenant is not allowed to smoke in the rental property.

If you find that a tenant has violated a no-smoking policy, you can potentially evict them. Still, following legal procedures and providing sufficient evidence to support your case is important. By doing these things, you can make sure that your no-smoking policy is followed and that all of your tenants are safe.
