What should you do if your neighbor violates the rules of cohabitation?

Shared living in Edmonton is becoming an increasingly popular way to reduce rental costs. However, shared living also increases the risk of conflict. When a neighbor breaks the rules—whether it's loud parties, unpaid utility bills, a dirty shared kitchen, or an unwanted guest who is constantly staying with you—many people are at a loss. They don't know if they have the right to demand change and how to do so without risking losing their voice or ending up in court.

Unlike landlord-tenant relationships, which are regulated by law (Residential Tenancies Act), neighbor relationships are in a legal “gray area.” RTDRS (Residential Tenancy Dispute Resolution Service) does not handle disputes between neighbors — only between landlords and tenants. This means you will have to rely on yourself, specialized mediators, or the courts.

This article gives you a practical step-by-step plan for dealing with a situation where your neighbor is breaking the rules of communal living.

Step 1: First, try talking one-on-one

It sounds simple, but many conflicts start because people never talk to each other directly about the problem. Often, the person breaking the rules doesn't even realize they are causing a problem. Sometimes people are raised differently or have different expectations about what is considered “normal” behavior.

Choose a calm time when you are both in a good mood. Don't wait until you are angry after a loud party at 3 a.m. The morning, when you have both slept, will be much better. Speak in a calm voice, without accusations. Instead of saying, “You're always making noise and you're careless,” say, “I have trouble sleeping when loud music is playing after 11 p.m. Can we agree to keep the music down after 11 p.m.?” This describes the problem without attacking the person's character.

Give specific examples. Don't say, “You're always dirty.” Say, “On Tuesdays and Fridays, dishes pile up in the sink, and it attracts bugs.” Specific facts are easier to discuss than general accusations. Ask about the cause of the problem. Maybe your neighbor isn't paying their utility bills because they're having financial difficulties that they're embarrassed to talk about. Maybe they didn't know that their guests weren't supposed to stay with you permanently. Understanding the cause often gives you a path to a solution.

After the conversation, send your neighbor a short message (via WhatsApp, email, or a physical note) confirming what you agreed on. For example: "Hi! Thanks for talking today. Just to be clear: after 11 p.m., we'll both listen to music quietly. Starting Monday. Thanks for your understanding!" This is proof that an agreement was made.

Step 2: If the conversation didn't help — a written warning

If your neighbor continues to violate the agreement after a personal conversation, it's time to write a formal letter. This makes the matter serious and creates a documented history of violations that you may need later.

Write briefly and clearly. The letter should not be a long tirade of insults. It should be businesslike and factual. Start by reminding them of the date of the previous conversation and what you agreed upon. Then write how the neighbor continued to violate the agreement. Provide specific dates and times, if possible. “We agreed on December 1 that the music would be turned off after 11 p.m. However, on December 5 at 1:30 a.m., I heard loud music. On December 8, the same thing happened at 12:45 a.m.” These details show that this is not a one-time incident, but a systematic problem.

Indicate how this affects you. “This prevents me from sleeping, which affects my health and work.” Remind them of the previous agreement and ask them to stick to it. Set a reasonable deadline for change. For example: “I ask you to stick to our agreement from now on. If the noise continues after 11 p.m., I will be forced to consider further steps.” End professionally, without threats. Don't write, “If you do this again, I'll evict you.” Just say, “I hope we can resolve this amicably. Please contact me if you need help complying with our agreement.”

It is best to deliver the letter in person. Show it to your neighbor, make sure they have read it, and ask for a written receipt (just a short note with the date and signature). If your neighbor refuses, leave the letter in a visible place on their door and take a photo.

If you can't deliver it in person or are afraid of conflict, send it by registered mail or via SMS/WhatsApp (screenshot the message as proof). Registered mail is more official and confirms receipt. Always keep a copy of the letter for yourself along with proof that your neighbor received it.

Step 3: Gather evidence

If the conflict is not resolved, you may need proof that your neighbor has indeed violated the agreement. Documentation becomes critical at this point.

  • Keep a log of violations: Buy an inexpensive notebook and record each violation with the date, time, and description of what happened. For example: “December 12, 1:15 a.m. — loud music from neighbor's room, lasted 45 minutes, despite written warning on December 10.” The more records you have, the more convincing your case will be if it goes to court.
  • Photos and videos: If the problem is a dirty kitchen, take a photo. If it's noise, try recording it on your phone (maximum 30 seconds to show the scale). This evidence is difficult to dispute — it's objective information.
  • Correspondence: If you correspond with your neighbor via SMS, WhatsApp, or email, do not delete these messages. They serve as proof of communication and agreed arrangements.
  • Witnesses: If other neighbors have also been affected by disturbances (loud music, etc.), ask them to write a short letter or give verbal testimony later. “I also heard loud music on December 5 at 1:30 a.m. and couldn't sleep” — such testimony strengthens your position.

Step 4: If the problem is with utility bills

This is a slightly different situation because it involves money rather than behavior.

First, make sure the calculation is correct. Sometimes utility bills suddenly increase due to technical reasons (meter error) or objective reasons (cold winter, car heaters running). If both parties pay a more fairly calculated amount, the neighbor will be less resistant.

Tell your neighbor: “Your share of the utility bill is $X. Please transfer the money by [date].” It is better if the bill is in one person's name (for example, yours) and your neighbor simply transfers their share to you. If both of you are on the bill, it becomes more complicated.

The free app Splitwise not only splits current bills, but also tracks debts. If your neighbor enters their debt into the app, it creates an official record of how much they owe and for what. If your neighbor doesn't pay, don't pay their share with your money. If the meter is in your name, the landlord or utility company will demand the full amount from you, but that doesn't mean you have to pay. Instead, tell the billing organization that there are two of you and you only pay your share (if possible). If not, give the neighbor's name and the amount they owe, and give them more time to pay.

When the neighbor finally pays, ask for proof of payment (a transfer receipt). This is proof that they have paid their debt. If your neighbor refuses to pay, you can file a claim in small claims court (for amounts under $100,000), but the cost of pursuing the case (approximately $100-200 filing fee) may exceed the debt. Often, it is not worth the time and emotional expense.

Step 5: Difficult situations – loud parties, guests who stay permanently

If your neighbor regularly throws loud parties or allows their guests to stay permanently in the house, this is a different level of problem.

Under Edmonton's Community Standards Bylaw, most noise is only permitted between 7:00 a.m. and 10:00 p.m. After 10:00 p.m., noise must not exceed 65 decibels (dB) in residential areas. This is equivalent to a normal conversation.

If the problem is loud music, first try talking to the person and giving them a written warning (as described above). If that doesn't help, you can file a complaint with Edmonton 311 or the Bylaw Complaint Service website. Call 311 (from 7 a.m. to 7 p.m.) or 780-442-5311 (outside the city) or 780-508-9200 (after hours, if the situation is truly critical).

When you file a complaint, provide as many details as possible: when it happened, how long it lasted, which room the noise is coming from, how often it recurs. Initial complaints often do not result in immediate action, but if you file multiple complaints with a documented history, municipal authorities will launch an investigation.

The police also have the right to intervene. If you call the Edmonton Police Service non-emergency number and report noise that is disturbing your peace, an officer may come and issue a warning to your neighbor. This is not an arrest or a fine on the first offense, but it demonstrates the seriousness of the situation.

Under Alberta law, a landlord has the right to know who is living in the house. If your neighbor allows someone to live in their room permanently without informing you or the landlord, this may be a breach of your cohabitation agreement.

First, talk to your neighbor: “I've noticed that your friend is often staying here. If he plans to live with us long-term, we need to talk about it. Can he be considered a resident? How does this affect utilities and shared spaces?” Be clear, not aggressive.

If a guest lives in the house permanently, it affects utilities (more water, electricity), the shared kitchen, and bathroom. It is fair to ask the guest to contribute their share of the utility costs or to propose a fair division of the shared space.

If the neighbor refuses to resolve the issue, you can notify the landlord about the unauthorized extension of residence. The landlord has the right to intervene, as this may be a violation of the terms of the lease (lease agreements often specify how many people can live in the house).

Step 6: Specialized mediation

If conversations, written warnings, and documentation have not helped, you can turn to a professional mediator. Mediation is a process in which a neutral third party helps two parties find a mutually acceptable solution.

The mediator does not judge or pass judgment—they simply listen to both sides and help them understand each other's positions. Often, people are in conflict because they don't understand how the other person perceives the situation. A mediator helps to bridge this communication gap.

Mediation in Edmonton is offered by several organizations. For example, JRB Mediations offers mediation services for civil and community disputes. The cost is usually $100-300 depending on the complexity of the case and the number of sessions. This is much cheaper than court proceedings.

Important: both parties must voluntarily agree to mediation. If your neighbor refuses, you cannot force them. However, if they agree, mediation often provides the least confrontational solution.

Step 7: Legal Options – Small Claims Court or Justice of the Peace Court

If mediation doesn't work or your neighbor refuses, the last option is to go to court. However, be prepared for the fact that the legal process will take time and money.

This court handles civil claims for amounts up to $100,000. The filing fee is approximately $100-200, depending on the amount of the claim. The process is less formal than in a regular court, and people can often represent themselves without a lawyer (although a lawyer can help).

To file a claim in Small Claims Court, you need to have clear documentation (your written records, a log of violations, witness statements). The judge will review the evidence from both sides and make a decision.

Typical lawsuits from neighbors involve money (unpaid utility bills, damages from damage) or an order to stop certain behavior (stop loud music, remove guests). Important: A lawsuit in court will ruin your relationship with your neighbor almost forever. This is the last option when nothing else helps.

Step 8: When a neighbor grossly violates the rules – difficult cases

Some situations are more serious than others. If your neighbor is aggressive toward you or threatens you, uses drugs in your shared space, commits sexual or physical abuse, or if you need immediate assistance, contact the police immediately. Do not wait for written warnings. Edmonton Police has an emergency number, 911, for dangerous situations.

If the problem is aggression or threats, you don't even need to keep your neighbor in the house. You can ask the police to remove them as a trespasser from your property.

Step 9: Removing your neighbor from your home

If you are the owner (or primary tenant) of your home and your neighbor is a subtenant or guest, you may need to remove them.

You can give them a written order to leave the house. In most cases, it is considered fair to give 1 month or a reasonable period of time. The written notice may read as follows: “I am informing you that your right to live in this house ends on [date]. Please vacate the premises by [date].” Send it by certified mail or deliver it in person.

If your neighbor refuses to leave after this date, you can contact the police to have them removed as trespassers. The police will not physically remove them, but they can warn them that they are no longer welcome on your property.

If your name is also on the lease, you two are technically equals, and you will need the landlord's help to remove them. If your name is on the lease and theirs is not, you can give them a written order to leave (as described above).

If the landlord agrees to remove the neighbor, it will be a formal eviction, which requires a court order and following the proper procedure. This can take 1-3 months.

Step 10: Prevention – how to avoid these problems in the first place

It is wiser to prevent problems than to solve them later. When you are looking for a new roommate or moving into a new place with a roommate, do the following:

  • Written Roommate Agreement: Always, ALWAYS have a written agreement, even if you trust your roommate. The agreement should include: how utilities are shared (%), whose name is on the bill, what hours are considered “quiet hours,” guest policy (how often, how long), rules for shared spaces (kitchen, bathroom), what to do if one person wants to move out mid-term, and utility payment deadlines.
  • Implement systems from the beginning: Set up Splitwise to track utilities from day one. Agree on “quiet hours” (for example, from 11 p.m. to 7 a.m.). Define expectations regarding guests: can they sleep over, how often can they visit.
  • Choosing a neighbor: When you're looking for a neighbor, talk to them before they move in. What's their work schedule? Do they often have guests? How long have they lived in the area? Do they have a stable income to pay for utilities? Invite them for coffee before handing over the keys and do a check: this is a lab for discussing important points.

Final logic: The path from problem to solution

If your neighbor breaks the rules, follow this procedure.

  1. First, talk one-on-one calmly and specifically.
  2. Write a written warning if the conversation does not help.
  3. Collect evidence — a log, photos, screenshots.
  4. Try professional mediation.
  5. Contact local authorities (311 for noise, landlord for illegal residents).
  6. Consider Small Claims Court for monetary claims.
  7. In emergency situations (violence, threats), contact the police.

Living together requires patience and communication. But you have rights, and you should not have to tolerate constant violations of agreements. Document everything, be polite but firm, and seek professional help when you need it.
