The short answer: British Columbia's maximum allowable rent increase for 2027 is 2.2%, announced on 27 August 2026 and effective 1 January 2027. It applies to an existing tenancy, once in any 12-month period, and needs three full months of written notice on form RTB-7. That makes the real date 30 September 2026 — miss it and a 1 January increase is not legal. On a Kamloops two-bedroom at the last published average asking rent, 2.2% is $41.58 a month. Seven straight caps from 2021 through 2027 compound to 15.4% in total, which is less than Kamloops asking rents moved in the single year to October 2025.
The maximum allowable rent increase is the most a landlord may raise rent on a sitting tenant in a 12-month period. In BC it is set annually and pegged to the 12-month average change in the provincial Consumer Price Index. Until 2019 the formula was that index plus two percentage points; the two-point buffer was removed.
The 2.2% number will be repeated everywhere this month. It is the least useful thing about the announcement.
The deadline, which is the actual news
Three full months of written notice are required before an increase takes effect. So for an increase on 1 January 2027, the tenant must have the notice by 30 September 2026.
Two details make this trip people up more than it should.
The notice has to be the form. BC requires the RTB-approved Notice of Rent Increase, form RTB-7. A text message, an email, or a conversation is not valid notice, no matter how clearly it was worded or how amicably it was received.
Three full months means full months. Notice served on 15 June does not permit an increase on 15 September. The clock runs to the first full rental month after three complete months, so the earliest effective date is 1 October.
The third detail is the one that saves money this autumn: the cap that applies is the one for the year the increase takes effect, not the year you serve the notice. A notice served in September 2026 for a January 2027 increase uses 2.2%, not 2026's 2.3%. Using last year's number on next year's notice is the most common way these get served incorrectly.
If you miss 30 September, nothing is lost permanently. The increase simply moves to the earliest month it can legally take effect.
Seven years of caps
The cap is not new and the trend matters more than any single year.
| Year | Maximum allowable increase |
|---|---|
| 2019 | 2.5% |
| 2020 | 2.6% |
| 2021 | 0% (pandemic freeze) |
| 2022 | 1.5% |
| 2023 | 2.0% |
| 2024 | 3.5% |
| 2025 | 3.0% |
| 2026 | 2.3% |
| 2027 | 2.2% |
The Housing Ministry's framing is that 2027 is the seventh consecutive year the increase has been held at or below inflation. That is their characterisation, and the series above is there so you can form your own.
Compound the seven caps from the 2021 freeze through 2027 and you get 15.4% in total. A tenancy that began in 2021 at $1,500 could legally be at $1,730.86 by 2027 — assuming the landlord served a correct notice every single year, which most do not.
What 2.2% is actually worth
Abstract percentages are how landlords talk themselves into and out of decisions. Here is the arithmetic on a real market.
The last figures I published for Kamloops, from the rental market research I ran, had average asking rents of $1,520 for a one-bedroom and $1,890 for a two-bedroom in October 2025, up 6.2% and 7.4% year over year.
On that two-bedroom, 2.2% is $41.58 a month. About $499 over the year.
Now put the two numbers beside each other. Market asking rents in Kamloops moved 7.4% in one year. The cap allows 2.2%. Three years of caps on a sitting tenancy amount to less than that single year of market movement.
That gap is the whole finding, and it points somewhere unexpected. The annual increase is close to a rounding error in your underwriting. The initial rent is the number that decides the outcome, because it is the one you compound from and the only one you fully control.
What the cap does not touch
Rent is capped. The costs that rent pays for are not.
| Capped by the province | Not capped |
|---|---|
| Rent on an existing tenancy | Property taxes |
| Manufactured home pad rent (2.2% plus a proportional amount for local government levies and regulated utility fees) | Landlord insurance |
| — | Strata fees and special levies |
| — | Mortgage payments at renewal |
| — | Maintenance, turnover and vacancy costs |
| — | Initial rent on a new tenancy |
In the BC Interior the insurance line deserves particular attention, because wildfire exposure prices into it and nothing about the rent cap moves with it. What a BC Interior rental actually costs to run budgets $150 a month for landlord insurance on a single-family rental, and that is a line that has been going one direction.
There is a route above the cap. It requires either the tenant's written agreement, or an application to the Residential Tenancy Branch for an Additional Rent Increase — for expenses, or for capital expenditures such as a roof or major mechanical work. It is a real application with a fee, an arbitrator, and tenant participation, not a form you file and forget. Worth knowing it exists. Not worth planning around.
The cap also does not reach commercial tenancies, non-profit housing where rent is geared to income, co-operative housing, or some assisted living.
The turnover question, answered honestly
BC has no vacancy control. The cap binds one landlord and one tenant, so when a tenancy genuinely ends, the initial rent for the next tenant is unrestricted.
I want to be careful here, because the arithmetic above points at a conclusion that is both obvious and wrong.
The unit has to genuinely become vacant. Ending a tenancy in bad faith to re-price it carries a 12-month occupancy obligation and real penalties, and the Residential Tenancy Branch hears these cases regularly. That is the legal answer.
The practical answer is stronger. Turnover costs a month of vacancy, cleaning, repairs, listing time, and the risk of a worse tenant. In a market with 1.4% vacancy, a tenant who stays four years — which is what one Kamloops property manager reported as her average — is worth considerably more than the gap you would close by churning them. The gap is visible and the churn cost is not, which is exactly why people get this wrong on a spreadsheet.
So the honest version: price it correctly at the start, serve your notice properly every year, and treat a long tenancy as the asset it is.
What this changes in your underwriting
- Model 2.2%, not 5%. For a property with a sitting tenant, use the cap as your rent growth assumption. Market growth only reaches you at turnover, and turnover is not a plan.
- Get the initial rent right. Pull current comparable listings for that specific unit type in that specific neighbourhood, not the city average. This is the number you live inside for the length of the tenancy.
- Diarise 30 September, every year. One missed notice is a full year at the old rent, and the loss compounds through every subsequent year's base.
- Grow the expense lines faster than the rent line. Insurance, taxes and strata fees are not capped. If your model grows both at the same rate, it is wrong in the direction that flatters the deal.
- Underwrite turnover honestly. Put a real vacancy allowance and a real make-ready cost in the model, then check whether the reset rent still justifies it. Usually it does not.
- Check what the existing tenancy actually pays before you offer. A long-tenured unit at well under market is a different asset from a recently re-let one, and the difference does not show up in the listing.
For the version of this worked line by line on a real property, underwriting a Kamloops duplex is me doing exactly that. The suite arithmetic post covers the same discipline for an added unit and carries the 2026 figure of 2.3% — the 2027 number above supersedes it for next year.
Common questions
What is the maximum rent increase in BC for 2027? 2.2%, effective 1 January 2027, announced by the province on 27 August 2026. It applies once in any 12-month period to an existing residential tenancy. Manufactured home park tenancies are capped at the same 2.2%, plus a proportional amount for changes in local government levies and regulated utility fees.
When do I have to give notice for a 1 January 2027 increase? By 30 September 2026. BC requires three full months of written notice on the RTB-approved form, RTB-7. Notice by email, text or conversation is not valid. Miss the date and the increase moves to the earliest month it can legally take effect.
I am serving notice in 2026 for 2027 — which percentage applies? 2.2%. The cap that governs is the one in force for the year the increase takes effect, not the year the notice is served. Using 2026's 2.3% on a notice that takes effect in January 2027 makes the notice wrong.
Can I raise the rent more than 2.2%? Only with the tenant's written agreement, or by applying to the Residential Tenancy Branch for an Additional Rent Increase for expenses or capital expenditures. That is a formal application with a fee and an arbitrator hearing where tenants take part, so it suits major capital work rather than routine cost pressure.
Does the cap apply when a new tenant moves in? No. BC has no vacancy control, so the initial rent on a genuinely new tenancy is unrestricted. That is not a licence to turn tenants over — ending a tenancy in bad faith carries a 12-month occupancy obligation and penalties, and vacancy and make-ready costs usually exceed the rent gap anyway.
The honest summary
The headline number is small and it is not really the story. Three things are.
The date is the story for this month. 30 September 2026 is the last day to serve notice for a 1 January increase, it has to be form RTB-7, and it has to use 2.2% rather than this year's 2.3%.
The compounding is the story for your model. Fifteen point four percent across seven years, against a market that moved 7.4% in one, means the annual increase is not where the return lives. The initial rent is.
And the squeeze is the story for the next few years. Rent is capped and insurance, taxes and strata fees are not. A model that grows both lines at the same rate is not conservative, it is wrong.
None of this makes BC Interior rentals a bad asset. It makes them an asset where the entry price and the first rent matter far more than anything you do annually afterwards, which is a reasonable thing for a rule to encourage. It just needs to be in the spreadsheet before you offer, not discovered in year three.
