Can I Build a Garden Suite in Edmonton? RS Zone Rules & Guide 2026
Edmonton doesn’t call them “garden suites” anymore — and the rules changed with the name. Here are the RS zone requirements that decide whether your lot qualifies, the size, height, and setback limits that apply in 2026, and what the permits actually cost.

The short answer: yes — if your lot qualifies
Most Edmonton homeowners on a standard residential lot can build a garden suite. The City actively encourages them as gentle density. But “can” depends on three things: your zone allows it, your lot fits the setbacks and coverage limits, and you pull the right permits.
In practice, that means:
- Zone: your property must be in a zone where backyard housing is a permitted use — the RS (Small Scale Residential) zone, which covers most mature neighbourhoods, qualifies.
- Fit: the suite must meet the height, setback, site-coverage, and building-separation rules in Section 6.10 of the zoning bylaw (table below).
- Paperwork: a development permit and a building permit, both from the City of Edmonton.
Get those three right and there’s no rezoning, no variance hearing, and no neighbour vote. Miss on any of them and the project stalls before it starts — so verify the fit before you spend a dollar on drawings.
Garden suite vs. backyard housing: the name changed
If you built — or researched — a garden suite under the old Zoning Bylaw 12800, forget most of what you remember. The old rules capped garden suites at 37.2–65 m², limited height to 4.5 m, and issued temporary permits of max 5 years, renewable on application. That entire regime is gone.
Under the current bylaw, a garden suite is Backyard Housing: “a building containing 1 or more dwellings, located wholly within the rear yard” of a residential site. The practical differences:
- Permanent, not temporary. No 5-year expiry hanging over the investment.
- More forms allowed. Single-detached, semi-detached, and multi-unit configurations — not just one box behind the garage.
- Can come first. Backyard housing may be built on a vacant lot before the principal dwelling — useful for phased builds.
- Self-contained by definition. To qualify, the space needs its own kitchen, bathroom, sleeping area, and living area.
Don’t trust old guides
Edmonton replaced its zoning bylaw and the RF1/RF2/RF3 zone names along with it. Any article telling you your lot is “RF1” or quoting the 5-year temporary permit is describing a system that no longer exists. When in doubt, check the current bylaw or call 311 and ask for a development planner.
Does your lot qualify? Start with the RS zone
The Small Scale Residential (RS) zone is Edmonton’s most common residential zone — it covers the bulk of mature neighbourhoods built out before the bylaw renewal. Backyard housing is a permitted use there, which is the key detail: permitted means no rezoning application, just permits.
To confirm your zone:
- Go to maps.edmonton.ca.
- Enter your address and click ‘Find Address’.
- Read the ‘Current Zone’ field. If it says RS (or another zone listing backyard housing as permitted), you can proceed to design.
The RS zone has been in the news for its 2026 infill changes — most notably the principal-building height limit dropping from 10.5 m to 9.5 m on August 1, 2026. That change affects the main house, not your backyard unit, but if you’re planning a full infill-plus-suite project, read our Edmonton infill rules 2026 guide alongside this one.
The rules that decide your design
Section 6.10 of the zoning bylaw sets the hard numbers for backyard housing. These are the ones your designer needs on page one:
| Regulation | Requirement |
|---|---|
| Maximum height | 6.8 m — or 4.3 m where the rear lot line abuts a residential site with a max height of 12.0 m or less |
| Maximum site coverage | 20% of the site area |
| Maximum second-storey floor area | 60 m² per dwelling (70 m² where inclusive-design requirements are met) |
| Maximum second-storey wall length | 15.0 m for any wall containing backyard housing |
| Minimum setback (side) | 1.2 m |
| Minimum rear setback abutting an alley | 0.6 m (where there’s no garage or the garage door doesn’t face the alley) |
| Separation from the principal dwelling | 3.0 m minimum |
Three of these surprise first-time builders most. Site coverage is measured across the whole lot — house, suite, garage, and all — so a big existing footprint eats your suite budget fast. Height drops to 4.3 m if your rear neighbour is low-rise residential, which rules out a two-storey suite on many interior lots. And the 3.0 m separation from the main house quietly kills narrow-lot designs that look fine on paper.
One more thing people ask about: can you have both a basement suite and a garden suite? The bylaw doesn’t forbid it — a secondary suite (inside the house) and backyard housing (detached) are different use classes. But each must independently satisfy every regulation, and the combined project still has to fit the zone’s density, coverage, and setback limits. Get a development planner’s read before you design around both.
Permits: development + building, and what they cost in 2026
Backyard housing needs two City permits: a development permit (zoning compliance) and a building permit (Alberta Building Code compliance), plus trade permits for electrical, plumbing, and gas. They’re applied for together through the City’s self-service portal.
For 2026, the City’s fee schedule prices a combined backyard-housing permit (unit up to 1,650 sq ft, standard wood-frame) at $2,241.50 all-in — covering the $625 development application, building/mechanical, wiring, electrical safety codes, and lot grading fees. Extras the schedule calls out: the underground electrical trench between house and suite needs its own conduit inspection fee, and anything beyond the standard scope (hot tub, deck, gas heater) is permitted separately.
On timeline: straightforward compliant applications move in weeks; anything needing relaxations or dealing with servicing upgrades (sewer, water, power) takes longer. The City runs monthly secondary-suite and infill pre-application workshops — worth attending before you submit, since a rejected application costs more time than the workshop ever will.
What it costs — and what it can earn
The build itself is the real money. Edmonton builders currently quote roughly $200,000 to $500,000+ for a garden suite depending on size, finishes, and site conditions — servicing upgrades, tricky grading, and custom design all push toward the top of that range. Budget for design, utility connections, permits, and landscaping on top of the construction number, and get at least two builder quotes before you commit.
Against that, a legal self-contained unit generates real income from day one. Rents for 1–2 bedroom backyard units in Edmonton run well into four figures per month in the current market — verify against live rental listings when you underwrite, but the math that matters is simple: at typical rents, a garden suite can carry a meaningful share of the property’s mortgage while the land underneath keeps appreciating.
There’s also the resale angle. A legal, permitted suite — basement or backyard — measurably widens your buyer pool when you sell: investors, multi-generational families, and house-hackers all pay attention. An unpermitted suite does the opposite, becoming a negotiation weapon for the buyer’s side. If you build, permit it properly and keep the paperwork; it’s part of the asset.
Build vs. buy: the faster path to suite income
Building is a 6–12 month project with $200,000+ on the line before the first rent cheque. There’s nothing wrong with that — but it isn’t the only way to own suite income in Edmonton. Buying a home that already has a legal secondary suite gets you rental income from possession day, with the suite’s legality already established and reflected in the price.
If that route appeals, start with what’s actually on the market:
- Homes with legal secondary suites in North Edmonton
- Secondary suite homes for sale in St. Albert
- Homes with legal secondary suites in Sherwood Park
And if you’re weighing build-vs-buy on the numbers, recently sold homes in Edmonton and area will ground your expectations on what suited properties actually trade for — which is the number your entire pro forma hangs on.
Key takeaways
Edmonton’s “garden suites” are now Backyard Housing under Zoning Bylaw 20001 — permanent dwellings with their own kitchen, bath, sleeping, and living areas. On an RS-zoned lot they’re a permitted use: no rezoning, just a development permit and building permit (about $2,240 in City fees for 2026). Design to the hard limits — 6.8 m height (4.3 m against low-rise neighbours), 20% site coverage, 60 m² second storey, 1.2 m setbacks, 3.0 m from the house. Expect a $200,000–$500,000+ build cost, and verify your zone at maps.edmonton.ca before spending anything on drawings.
Frequently asked questions
Is a garden suite the same thing as backyard housing in Edmonton?
Yes. Under the current Zoning Bylaw (20001), what used to be called a garden suite or garage suite is regulated as “Backyard Housing” — a self-contained dwelling in the rear yard. The old garden-suite rules, including the 5-year temporary permit, no longer apply.
Can I build a garden suite on an RS-zoned lot without rezoning?
In most cases, yes. Backyard housing is a permitted use in the RS (Small Scale Residential) zone, so a qualifying project needs a development permit and building permit — not a rezoning. Confirm your lot’s current zone at maps.edmonton.ca first.
What is the maximum size of a garden suite in Edmonton?
Under Section 6.10: maximum 6.8 m height (4.3 m where the rear lot line abuts a residential site capped at 12.0 m), 20% maximum site coverage, and a maximum second-storey floor area of 60 m² per dwelling — 70 m² where the project meets inclusive-design requirements.
Do I need a permit to build a garden suite in Edmonton?
Yes — both a development permit and a building permit, plus trade permits. For 2026 the City’s combined backyard-housing permit fees for a unit up to 1,650 sq ft total $2,241.50.
Can I have both a basement suite and a garden suite on the same property?
Possibly. A secondary (basement) suite and backyard housing are different use classes and the bylaw doesn’t forbid having both — but each must independently meet all regulations, and the total development must fit the zone’s density, coverage, and setback limits. Confirm with a City development planner before designing around both.
