Ottawa Short-Term Rentals in 2026: The Rules Rewrote the Investor Playbook
Short-term rental investing in Ottawa is not a grey market. Instead, it is a rulebook. The 2026 rulebook is direct: short-term rentals operate only inside your principal residence. If you buy a property and try to run it as an Airbnb, the by-law does not negotiate with you. However, an investor reading the definition carefully will notice the door it leaves open. A stay under 30 consecutive nights is a short-term rental. A stay of 31 days or more is a different market that the STR by-law does not touch. That single line is where Ottawa’s furnished-rental returns now live. In addition, it is why “near me” search demand for furnished mid-term housing keeps growing with the federal workforce.
Key Takeaways
- Ottawa permits short-term rentals only in the host’s principal residence. Therefore, investment properties, cottages-as-products and second homes are out.
- Renting your entire home short-term is capped at 180 nights per calendar year. In contrast, private rooms inside your residence carry no night cap.
- A stay under 30 consecutive nights is a short-term rental under the by-law. Specifically, at 31 days or more you are outside the STR regulatory framework entirely.
- Licensing runs roughly $100–$200/year depending on permit type. In addition, Ottawa’s municipal accommodation tax adds 4% on occupancy.
- Provincial enforcement behind municipal by-laws can carry fines up to $100,000 for individuals. As a result, this is not a slap-on-the-wrist space.
The Rules as They Stand in October 2026
Three boundaries define the game. First, the 30-day line: rent by the night or week on your own home and you are in the STR framework. Any tenancy of 31 days or more is a residential rental, not an STR. Second, the principal-residence rule: the property you list must be the home where you ordinarily live. This is precisely why investment properties cannot legally operate as Airbnbs in Ottawa. Third, the night cap: entire-residence rentals max out at 180 nights per year. Meanwhile, renting spare rooms inside your residence is not night-capped.
Hosts hold one short-term rental permit, with at most one additional rural cottage rental. Permits run in the $100–$200 range per year by type. In addition, guests pay Ottawa’s 4% municipal accommodation tax on top of the rate. Enforcement is where the seriousness shows. For instance, Ontario’s enforcement powers behind municipal by-laws can reach $100,000 in fines for individuals. Furthermore, cities have shown no hesitation in using registration data to find violators.
Why Investment Properties Are Out — and What Qualifies Instead
The structure is blunt: a property you do not occupy cannot be a legal Airbnb in Ottawa. However, two legitimate paths remain. Path one is a suite inside your own principal residence. For example, a legal basement or in-law suite operating as an Airbnb or a furnished long-term unit while you live upstairs. That is a homeowner strategy, not an acquisition strategy.
Path two — and the one investors keep asking us about — is the furnished mid-term rental. Specifically, a lease of 31 days or more furnished, aimed at people who are in Ottawa for a season, not a sabbatical. Because the tenancy clears the 30-day line, it is simply a rental under tenancy law. As a result, there is no accommodation tax, no night caps, and no permit. In addition, the city has no rule against running them in investment properties.
The Mid-Term Pivot, by the Numbers
Baseline the math with the long-term market. The city’s average asking rent was about $2,145/month in mid-2026. Therefore, a 12-month unfurnished lease at that rate grosses roughly $25,740. A furnished mid-term at an equivalent monthly rate would gross identically per occupied month. However, the real difference is who the tenant is and how the calendar fills.
Ottawa’s mid-term demand sources are the most stable in the city. For instance, federal secondments running the length of departmental postings, hospital rotations and residencies, defence relocation windows and contract engineering assignments. Marketplace pricing across Canadian cities consistently shows furnished executive rentals commanding a meaningful premium over unfurnished equivalents. Therefore, treat the exact spread as deal-specific to your unit and parking, rather than a rule of thumb.
As an illustration, a 3-month government secondment at $3,250/month grosses $9,750 with zero re-listing labour between bookings. In contrast, a 12-month lease at the $2,145 city average grosses $25,740. Two different calendars, two different tenant risks — model both before you buy.

Where the Demand Concentrates
Mid-term demand clusters where the employers are. Specifically, the federal core and government-adjacent office zones, the hospital cluster around The Ottawa Hospital’s campuses, defence facilities and the university district during semester cycles. A furnished two-bedroom priced for a hospital-rotation tenant leases through a different channel than the student September rush. As a result, a mixed long-lease and mid-term strategy on the same building smooths the calendar.
Rate context helps returns right now. For instance, after the Bank of Canada’s September 2, 2026 hold at 2.25%, financing stays near cycle lows. In addition, CMHC housing datasets at cmhc-schl.gc.ca provide benchmarking. Likewise, the provincial side of rental law is at ontario.ca.
Frequently Asked Questions
Can I run an Airbnb on an investment property in Ottawa?
No. Ottawa’s short-term rental framework permits hosting only in the operator’s principal residence. Therefore, a property you own and rent to someone else cannot carry a legitimate STR permit in the city.
How many nights per year can I rent my home short-term in Ottawa?
Entire-residence rentals are capped at 180 nights per calendar year. However, renting private rooms inside your residence is not night-capped, subject to the same permit and residence rules.
What counts as a short-term rental under Ottawa’s by-law?
Any paid occupancy under 30 consecutive nights. Specifically, a tenancy of 31 days or more is a residential rental — outside the STR by-law entirely. As a result, it is open to investors on properties they own.
What does an Ottawa short-term rental permit cost?
Roughly $100–$200 per year depending on permit type. In addition, guests pay the 4% municipal accommodation tax on their stays. Permits are issued per host, with at most one additional rural cottage rental.
What are the penalties for running an illegal short-term rental?
By-law enforcement backed by provincial powers can reach $100,000 for individuals and up to $500,000 for corporations. Furthermore, registration records make violators easy to identify. Therefore, treat unpermitted hosting as a real financial risk, not a technicality.
What is the mid-term alternative for investors?
Furnished rentals of 31 days or more aimed at government secondments, hospital rotations and contract work. Specifically, the tenancy sits outside STR regulation. In addition, Ottawa’s federal core makes it one of the sturdiest mid-term demand bases in Canada.
