Can You Airbnb a Backyard Suite in Ottawa?

The Short Answer: No — But the Full Picture Matters

If you've built — or are planning to build — a backyard suite, coach house, or garden suite in Ottawa, one of the first questions most homeowners ask is: can I put it on Airbnb?

The short answer is no, under almost all circumstances. Ottawa's Short-Term Rental By-law (By-law 2021-104) prohibits using a backyard suite as a short-term rental, and the penalties for non-compliance are severe. But the story doesn't end there — understanding exactly why it's not permitted, the narrow exceptions that exist, and the legal income strategies that work instead is essential reading for any Ottawa homeowner with a secondary unit.

Ottawa's Short-Term Rental By-law: The Core Rule

Ottawa's Short-Term Rental By-law (No. 2021-104) governs any rental of a residential unit for fewer than 30 consecutive nights — which covers Airbnb, VRBO, and all similar platforms. The by-law's foundational rule is stated plainly:

"No person shall operate a short-term rental unless the dwelling unit is the principal residence of the host."
— Ottawa By-law 2021-104, §4(1)

Principal residence is defined as the property where you ordinarily reside — your main home. You can only have one principal residence. This single rule eliminates the vast majority of backyard suite Airbnb scenarios, for a simple reason: your backyard suite is a separate dwelling unit, not your principal residence. It's a distinct property with its own address, entrance, kitchen, and bathroom. You live in the main house. The suite is not your principal residence. Therefore, it cannot legally be used as a short-term rental.

This applies regardless of whether the suite is physically in your backyard, attached to your home, or located above your garage. If it's a separate dwelling unit and it's not the place you ordinarily live, it falls outside the by-law's permission.

What About Renting a Room or Basement Suite in Your Own Home?

Here's where the rules get slightly more flexible. If you live in your home and rent out a portion of that same home — such as a spare bedroom, a basement suite accessible from inside the main house, or a room while you're temporarily away — you may be able to operate a short-term rental provided you have a valid Host Permit.

Key requirements for a legal Ottawa short-term rental of your principal residence:

• Host Permit: Obtain a Short-Term Rental Host Permit from the City of Ottawa ($100 annual fee, renewable). Proof of principal residence, insurance, and a floor plan/parking layout are required at application.
• 4% Municipal Accommodation Tax (MAT): Collect and remit a 4% MAT on all short-term rental revenue under Ottawa By-law 2019-252.
• Safety standards: The unit must meet fire, safety, and insurance requirements.
• Platform registration: Only approved STR platforms (Airbnb, VRBO, etc.) are permitted to list Ottawa STRs. The City cross-references permit numbers with platform listings.
• Permit number displayed: Your Host Permit number must be prominently displayed on all listings and advertisements.
• Guest limits: Maximum 2 guests per bedroom, up to 10 guests total.

The critical point: even under this scenario, you're renting part of your home — not a separate dwelling unit. A legally defined separate coach house or garden suite does not become eligible simply because it's on the same property as your principal residence.

The Rural Cottage Exception

Ottawa's by-law includes one notable exception: the cottage rental permit. Rural homeowners and cottage owners located outside of urban village boundaries can obtain a separate $110 cottage rental permit that allows a secondary property — such as a vacation home or rural coach house — to be listed as a short-term rental, even if it's not the owner's principal residence.

This exception is rural-only. It does not apply to backyard suites or coach houses in Ottawa's urban, suburban, or village areas. If your property is within the City of Ottawa's urban or suburban boundary, this exception does not help you.

Enforcement: The City Actively Monitors Compliance

This isn't a theoretical risk. Ottawa actively enforces its STR by-law. The City cross-references listings on Airbnb and other platforms with its host permit database, and unlicensed or ineligible properties are flagged for enforcement action.

Penalties under By-law 2021-104 (as amended through By-law 2024-469) are severe:

• Minimum fine: $500 per offence
• Maximum fine: $100,000 per day the offence continues
• Because each day of violation is a separate offence, an extended illegal listing can result in fines that compound rapidly

Beyond fines, enforcement can result in permit revocation, forced removal of your listing by the platform, and reputational damage if your property is publicly identified in City enforcement actions.

What Income Strategy Actually Works for a Backyard Suite?

The good news: you don't need Airbnb to generate strong returns from a legal Ottawa backyard suite. Long-term rentals are substantially more reliable, lower-risk, and increasingly lucrative given Ottawa's tight rental market.

Long-Term Rental Income

A well-built, legal one-bedroom coach house or garden suite in Ottawa typically commands $1,500–$2,200+ per month in long-term rent, depending on size, location, and finish quality. At $1,800/month, that's $21,600 per year in gross rental income — with none of the operational complexity, platform fees, cleaning costs, guest management, and regulatory risk that come with short-term rentals.

Ottawa's rental vacancy rate remains very low, meaning well-located units with private entrances, modern finishes, and included utilities attract and retain quality long-term tenants quickly.

Medium-Term Rentals (30+ Nights)

Rentals of 30 consecutive nights or longer fall outside the definition of a short-term rental under Ottawa's by-law. This opens up a legal middle ground: furnished, medium-term rentals targeting government workers on posting, military personnel, consultants on contract, university researchers, and relocating families. Ottawa's large federal public service and tech sector create consistent demand for furnished medium-term accommodations. This strategy isn't subject to the STR by-law, but the Ontario Residential Tenancies Act may apply depending on the specific arrangement — consult a lawyer before setting up a medium-term rental program.

House-Hacking With a Primary Suite STR

If short-term rental income is truly your goal, a different property setup may work: live in a portion of your home, obtain a valid Host Permit for your principal residence, and rent out spare bedrooms or an internal basement suite (not a separate dwelling unit) as an Airbnb. This approach is legal in Ottawa provided you comply with all permit, MAT, and safety requirements.
