Kelowna's oldest blocks carry its smallest lots — and, since the province's 2023 housing reforms, some of its broadest permissions for a second home on the same title.
Written by Serge, Founder, Kelowna Carriage Homes
Downtown Kelowna's residential streets — the blocks around Marshall Street, Rowcliffe Park, Abbott Street, and the flats between Harvey Avenue and Okanagan Lake — were subdivided decades before the city adopted its current minimum lot standards. Many parcels run 40 to 50 feet wide, a fraction of what you'll find in Glenmore or Rutland. The housing stock is correspondingly old: character homes and post-war bungalows from the 1920s through the 1960s, many with a basement already dug and a foundation already poured.
That combination — a small footprint but often generous basement height — changes the math for adding a second home here compared to almost anywhere else in the city. It also means walkability is real, not a listing adjective: City Park, the hospital, the downtown core, and the lake are within a 10-minute walk of most of these streets, which matters when you're weighing what a tenant will pay for location versus square footage.
On a 45-foot-wide lot, a detached carriage house competes for space with required side-yard setbacks, a driveway, and whatever backyard the owner wants to keep. It is not ruled out — some downtown lots are deeper than they are wide, and a handful of larger, older parcels still exist south of Sutherland Avenue — but it needs a site check before anyone assumes it pencils.
A secondary suite conversion is usually the more realistic first option downtown. If the home already has a full-height basement, the work is largely interior: egress windows, a separate entrance, a kitchen, and the fire separation the building code requires — not excavation or a new foundation. That is one reason the conversion cost range of $60,000–$150,000 tends to land toward the lower end downtown, where the shell already exists.
Downtown lots fall under City of Kelowna Zoning Bylaw No. 12375, the same rulebook that governs carriage houses and secondary suites everywhere in the city. A detached carriage house is capped at 90 square metres (about 970 square feet), limited to one per lot, and cannot be stratified or sold off separately from the main house. Accessory buildings — the carriage house included — are limited to roughly 14% site coverage, which is where a narrow downtown lot starts to bind. Either use requires one additional parking stall at minimum 2.75 by 6.0 metres. Full detail is on the city's carriage houses and secondary suites page.
Layered on top of the municipal bylaw is the province's Small-Scale Multi-Unit Housing legislation, adopted November 30, 2023, which now requires most BC municipalities — Kelowna included — to permit more units on lots previously zoned for a single detached house. Downtown lots, already served by full municipal infrastructure, are exactly the kind of parcel this rule was written for.
A turnkey carriage home runs $350,000 to $550,000 depending on size and finish, roughly $400 to $550 per square foot for a smaller unit. A secondary suite conversion runs $60,000 to $150,000, with basement conversions in older downtown homes typically landing in the lower half of that range. Design and permitting take 3 to 5 months; construction runs another 5 to 8 months once permits are in hand, and the City of Kelowna's stated clean-application review window is 4 to 6 weeks.
On financing, the province's $40,000 Secondary Suite Incentive Program stopped accepting new applications on March 30, 2025 (existing approvals are still honoured). A federal $80,000 secondary-suite loan announced in December 2024 did not survive into the 2025 federal budget and has not been implemented. What is available: since January 15, 2025, CMHC-insured refinancing to fund a secondary suite, up to 90% of home value on properties valued under $2,000,000. A CleanBC rebate of up to roughly $5,500 is available for a ductless heat pump in the new unit, stackable with a BC Hydro rebate of up to $2,000.
On rent: Kelowna renters paid an average of $2,118 a month for a two-bedroom and $1,596 for a one-bedroom in 2025 (CMHC). The same report shows the Central Okanagan's rental vacancy rate rose to 6.4% in 2025, up from 3.8% the year before — worth saying plainly rather than glossing over, since a downtown location with hospital and lake proximity is one of the stronger arguments for staying competitive as vacancy loosens.
