Kelowna Secondary Suite Rules in 2026: Adding a Suite, Carriage House, or Multiplex Under the New Zoning

On March 18, 2024, Kelowna council rewrote the zoning on most residential lots in the city in a single sitting. Under BC's Bill 44, the typical suburban Kelowna lot is now pre-zoned for up to 4 dwelling units, with no rezoning application and, where a project fits the Official Community Plan, no public hearing. Since then fees have dropped and the rental market has cooled. This guide decodes the Kelowna secondary suite rules as they stand in 2026, covering carriage houses and multiplexes too, with honest math on whether building still pencils.

Kelowna Secondary Suite Rules at a Glance

• Most suburban Kelowna lots allow up to 4 units. The Core Area allows 5 or 6, but only on a limited number of large lots that can fit the parking.
• A property can add one secondary suite or one carriage house beside a single-family home, never both.
• A secondary suite caps at 90 square metres of net floor area and needs a building permit, City registration, and an occupancy inspection.
• Mid-range construction in Kelowna runs $330 to $430 per square foot before city fees.
• Kelowna cut development cost charges by 25 percent for two years starting August 4, 2026.
• CMHC puts Kelowna CMA rental vacancy at 6.4 percent, the highest of any Canadian metropolitan area, with the average two-bedroom at $2,118.

Bill 44 and the Kelowna Secondary Suite Rules: 3, 4, or 6 Units

BC's small-scale multi-unit housing legislation, better known as Bill 44, sets minimums cities must permit: 3 units on lots of 280 square metres or smaller, 4 units on larger lots, and 6 units near frequent transit. "Frequent transit" means a bus stop within a 400 metre walk served at least every 15 minutes on average through the day, so verify your stop against the City's qualifying list before counting on 6 units.

Kelowna adopted its implementing zoning bylaw amendments on March 18, 2024, ahead of the provincial June 30, 2024 deadline. The City's own framing is worth repeating: suburban areas allow up to 4 units per lot, while 5 or 6 units apply only to a limited number of large Core Area lots with adequate parking. For rezonings that align with the Official Community Plan, public hearings are now prohibited.

Do not confuse this with the four Transit-Oriented Areas (the Rutland, Hospital, and OK College exchanges plus Orchard Park Mall), a separate Bill 47 regime: up to 10 storeys within 200 metres of an exchange and no residential parking minimums within 400 metres.

The province tightened things again with Bill 25, expanding where a single detached home must be allowed both a secondary suite and a detached accessory dwelling unit, with compliant zoning due June 30, 2026. Lots over 4,050 square metres, unserviced lots, heritage-protected land, and Transit-Oriented Areas are exempt.

Kelowna Secondary Suite Rules: Size, Permits, and Registration

Under Kelowna Zoning Bylaw No. 12375, a secondary suite must sit within a single detached home, semi-detached unit, duplex unit, or townhouse unit on a lot with community water. The maximum net floor area is 90 square metres, about 970 square feet.

Every suite needs a building permit, and all secondary suites must be registered with the City. A building inspector must grant occupancy before the suite can be occupied. Those three items, permit, registration, and occupancy, are what "legal suite" actually means. Ask for proof of each.

Two practical breaks help tight lots: the suite's parking space may sit in tandem behind the principal home's in developments of 6 or fewer units, and the energized EV outlet requirement does not apply to secondary suites or carriage houses.

Carriage House Rules in Kelowna: Which Lots Qualify

Carriage houses are permitted on urban lots zoned RU6, RU1, or RU2 inside the Core Area, on RU6, RU1c, or RU2c lots outside the Core Area, and on rural RR1c, RR2c, and RR3c lots. That small "c" matters: an RU1 lot outside the Core Area without the c suffix does not qualify. The Core Area is an official designation in Kelowna's 2040 Official Community Plan.

Servicing is the other gate. A carriage house needs both community sanitary sewer and community water, unless the lot is at least 10,000 square metres. And a carriage house cannot be subdivided or stratified, so you can rent it out but never sell it separately.

Secondary Suite vs Carriage House: One Property, One Choice

The single most misunderstood point in the Kelowna secondary suite rules: where zoning permits, a property can have either one secondary suite or one carriage house in addition to a single-family dwelling, not both.

Both count as dwelling units, which matters when tallying how close a lot sits to its 4-unit ceiling.

The Cost to Build a Carriage House in Kelowna in 2026

Local builder pricing puts mid-range custom construction at $330 to $430 per square foot. Even a modest 900 square foot carriage house lands around $300,000 to $390,000 in hard costs before city fees. Permits and approvals typically run $3,500 to $8,000 or more, soft costs add 5 to 15 percent, plus a 10 percent contingency.

One named local example: Kelowna builder DeGroot Custom Homes advertises roughly $400,000 for up to 1,100 square feet, about 6 months of construction plus 3 to 5 months of planning and permitting. Treat builder figures as marketing, not quotes.

Going bigger? The City's Fast Track Infill Housing program offers pre-approved designs for 4 to 6 units, targeting both permits issued within 10 days of a complete application versus the typical 2 to 4 months. The same bulletin is blunt about multiplex fees: development cost charges of $99,000 to $235,000 depending on unit count and location, plus development engineering fees of roughly $60,000 to $100,000 for a 21 metre wide lot. Those figures predate the 2026 DCC reduction below, but they set the right order of magnitude: city fees on a multiplex can rival the cost of an entire carriage house.

If you are weighing a build against simply buying an income property, our investment guide walks through how we underwrite both.

Kelowna's 25 Percent DCC Cut: The 2026 Fee Break

On June 30, 2026, Kelowna council voted 7 to 1 to cut development cost charges by 25 percent for two years: savings of $9,000 to $13,000 per single-family home and $7,000 to $9,500 per apartment unit, with the City forgoing an estimated $20 to $25 million. The City's development fees page lists the reduction as effective August 4, 2026 until September 30, 2028.

The backdrop explains the move: Central Okanagan housing starts from January to October 2025 came in at 2,314 units, down from 3,719 over the same 2024 period. For a homeowner running carriage-house math, a 25 percent DCC cut is real money that was not on the table in July.

What a Kelowna Secondary Suite Actually Rents For in 2026

Here is where the honest math lives. CMHC's Rental Market Report released in December 2025 put vacancy in the Kelowna CMA at 6.4 percent, up from 3.8 percent a year earlier and the highest among Canadian metropolitan areas. Rutland, classic carriage-house territory, posted the metro's highest submarket vacancy at 7.5 percent.

Actual rents, per the same survey: the average one-bedroom in the Kelowna CMA rents for $1,596 and the average two-bedroom for $2,118. Compare that with the $2,200 to $3,200 per month DeGroot projects for a new carriage house. A brand-new detached unit can out-rent the average, but the builder projection sits above what CMHC measured, so underwrite with the measured number and treat anything above it as upside.

Financing a Secondary Suite in 2026: What Is Dead and What Works

Two programs still advertised on contractor websites are gone. BC's Secondary Suite Incentive Program, a forgivable loan of up to $40,000, stopped accepting applications after March 30, 2025. The federal Canada Secondary Suite Loan Program, announced in December 2024 at an $80,000 limit and 2 percent interest, was reportedly never made operational and was shelved in the 2025 federal budget, per industry reports.

What survived is the insured refinance route. Since January 15, 2025, homeowners adding a suite can use insured mortgage refinancing of up to 90 percent of the post-renovation value of the home, capped at a $2 million as-improved value and amortized up to 30 years. Financing cannot exceed project costs, the units cannot be short-term rentals, the owner or a close relative must occupy one unit, and the property can hold up to four units.

The Bank of Canada's policy rate stands at 2.25 percent as of July 15, 2026. Lenders can use suite rental income to help you qualify, but treatment varies by lender and insurer, so get it in writing from your broker.

Buying a Kelowna Home That Already Has a Suite

Building is one path. Buying a home where someone else absorbed the construction risk is the other. The Central Okanagan benchmark single-family home sat at $1,072,400 in July 2026, up just over 2 percent year over year. Since December 15, 2024, the insured mortgage cap is $1.5 million, so a benchmark-priced Kelowna house with a suite is reachable with less than 20 percent down, and 30-year amortizations now extend to all first-time buyers and all buyers of new builds.

Due diligence still rules: confirm the suite is registered and occupancy was granted. And note that West Kelowna is a separate municipality with its own bylaws; a lot across the bridge does not follow the Kelowna secondary suite rules covered here.

Key Takeaways

• Bill 44 pre-zoned most Kelowna lots for up to 4 units. The 6-unit tier applies only near qualifying frequent transit.
• One suite or one carriage house per property, never both, and each counts as a dwelling unit.
• Suites cap at 90 square metres and need a permit, registration, and occupancy inspection. Carriage houses need the right zone plus sewer and water, and can never be sold separately.
• A modest carriage house runs roughly $300,000 to $390,000 in hard costs before city fees. The 25 percent DCC cut softens the fee line until September 2028.
• Underwrite rents against CMHC's measured $2,118 two-bedroom average and 6.4 percent CMA vacancy, not builder projections.
• The $40,000 BC grant is closed and the $80,000 federal loan reportedly never launched. The live tool is the 90 percent insured refinance.
