Roommate Guest Rules: Partners, Overnights and Rent

Fair roommate guest rules set a clear overnight limit (many households use two to four nights a week per person), require a heads-up for longer stays, and say when a regular guest starts paying toward bills. In Ontario, a landlord generally can't ban guests, but a partner who moves in doesn't become a tenant just by living there, so the people on the lease stay responsible for the rent.

Guests are one of the most common sources of roommate tension. Here's how to set rules everyone can live with, handle the partner who's "basically living here", and keep the lease side straight.

Key takeaways

• Agree on numbers, not vibes: nights per week, notice, and quiet hours.
• Landlords generally can't ban guests in tenancies covered by the Residential Tenancies Act (RTA).
• An occupant isn't a tenant. A partner who moves in without the landlord's agreement usually has no lease rights and no lease obligations.
• Set a trigger for contributing, such as more than 10 nights a month.
• Write it into your roommate agreement so the rule exists before the conflict does.

What your landlord can and can't do about guests

Ontario's guide to the standard lease lists terms that "do not allow guests, roommates, any additional occupants" as examples of void terms that can't be enforced in RTA tenancies. The government's renting guide also says plainly that landlords can't ban guests.

That doesn't mean anything goes:

• Damage. Tenants must repair or pay for undue damage caused by them or their guests.
• Behaviour. The LTB's guide to the Act explains that a landlord can give a tenant notice over problems caused by the tenant's guest or someone else living in the unit, so a guest's conduct can put your tenancy at risk.
• Overcrowding. The LTB's N5 notice covers interfering with others, damage and overcrowding, so a landlord can act if the number of people living in a unit becomes a genuine problem.
• Condo rules. In a condo, building rules (for example, on amenity bookings or move-ins) still apply.
• Living with the owner. If you share a kitchen or bathroom with the owner or their close family, the RTA generally doesn't apply, and the owner's house rules on guests can be much stricter. Read your agreement.

The bigger question for most people isn't the landlord. It's the other roommates.

Fair house rules for guests

There's no legal standard for roommate guest rules, so the right answer is whatever your household agrees. These defaults work for a lot of shared homes:

Adjust for your home. A two-bedroom with one bathroom needs tighter rules than a large house with three bathrooms.

The partner who's "basically living here"

It usually happens gradually: a toothbrush, then a drawer, then five nights a week. Signs a guest has effectively moved in:

• They're there more nights than not
• They receive mail or packages at the address
• They have their own key
• Shared groceries, hot water and hydro use have noticeably risen
• Other roommates feel they can't use the common areas

How to raise it

Talk to your roommate, not their partner, and keep it about the arrangement rather than the person: "Sam's here most nights now, which is fine with us, but our bills have gone up and the bathroom's busier in the morning. Can we talk about what's fair?"

Then pick one of three paths:

1. Scale back to the agreed overnight limit.
2. Contribute. The partner chips in toward utilities, internet and shared supplies, and possibly a share of rent, under your roommate agreement.
3. Move in properly. Everyone agrees, the landlord is told, and the lease is updated if the landlord agrees.

Rent, utilities and the lease: occupant vs tenant

Occupant

A partner who moves in without signing the lease or being accepted by the landlord is usually an occupant. In general:

• They aren't responsible to the landlord for rent or damage under the lease (the tenants are).
• They have few or no rights against the landlord, and usually can't bring a case to the LTB.
• If the tenant they live with leaves, they generally have no right to stay.

Tenant

To become a tenant, the landlord normally has to agree, for example by adding the person to the lease. Ontario's standard lease requires the landlord's consent for an assignment or sublet, and says the landlord can't arbitrarily or unreasonably withhold it. See sublet and assignment in Ontario for how that works.

Can the landlord charge more?

In an RTA tenancy, rent increases follow set rules: generally at least 12 months apart, with 90 days' written notice on the proper LTB form, and, for most units, no more than the yearly guideline without LTB approval. The standard lease guide also says terms requiring fees or deposits the Act doesn't permit are void. If your landlord demands extra money because someone moved in, get advice from the LTB or a legal clinic before paying.

Utilities

If utilities are in a roommate's name, a long-term guest adds real costs. A simple fix is to split variable bills (hydro, gas) by the number of people actually living there, and fixed ones (internet) by the roommates. Our guide to utilities for Toronto renters explains which bills you're likely to see, and how to split rent fairly covers rent shares.

Template wording you can adapt

Add these clauses to your roommate agreement, changing the numbers to suit your home.

Overnight guests:

Each roommate may have overnight guests up to three nights per week. Please give the others a heads-up by text the same day. Stays longer than three nights in a row need everyone's agreement in advance.

Regular guests and costs:

If one roommate's guest stays more than 10 nights in a calendar month, we'll meet to review costs. Unless we agree otherwise, that roommate will pay an extra share of hydro, gas and shared supplies for that month, calculated as if the guest were an additional roommate.

Moving a partner in:

No one moves in, including a partner, without the agreement of all roommates. If we agree, we'll tell the landlord, and we'll update this agreement with the new rent and bill shares from the move-in date.

Responsibility:

The host is responsible for their guests' behaviour, cleaning up after them, and paying for any damage they cause.

Keys and safety:

Guests don't get their own keys, fobs or door codes without everyone's agreement.

If the rules aren't working

Revisit them at a house meeting rather than in the moment. If a guest situation turns into a bigger dispute about money or someone refusing to leave, our guide to dealing with a bad roommate covers mediation, Small Claims Court and when to get legal help. If anyone feels unsafe because of a guest, call 911 in an emergency.

Start with people who share your expectations

The simplest guest policy is one you agree on before signing anything. On ColivEase, you can chat with potential roommates before you commit, and roommates can form a team and apply for a home together, so you can settle house rules first. Meet potential roommates on ColivEase.

Bottom line

Pick clear numbers for overnight stays, agree when a regular guest starts paying, and write it down. Landlords generally can't ban guests in RTA tenancies, but a partner who moves in is usually an occupant, not a tenant, until the landlord agrees otherwise, so the people on the lease stay on the hook.
