Under Zoning Bylaw 20001, Edmonton’s Small Scale Residential (RS) zone permits up to eight dwelling units on a sufficiently large mid-block residential lot — roughly 75 m² of site area per unit, so about 600 m² for the full eight. That makes Edmonton among the most permissive big-city regimes in Canada, and it applies without any rezoning.
- Up to 8 units on a mid-block RS lot large enough to carry them; more than 8 is limited to corner sites
- Maximum height 10.5 m (three storeys), maximum site coverage 45% for the principal building
- Rear-yard units fall under Backyard Housing — 20% site coverage, 6.8 m height, 60 m² second storey
- No provincial sales tax and no Ontario-style development charges — Alberta’s real advantage
- No Edmonton municipal suite grant, and Alberta’s SHARP and RAMP are not suite programmes

Edmonton did something unusual: it rewrote its entire zoning bylaw at once, and the result is quietly the most permissive framework for adding homes to a residential lot of any major Canadian city. Vancouver and Toronto get the attention. Edmonton permits more.
Most Edmonton homeowners have no idea. Local search demand runs through permission questions — people looking up the zoning bylaw — rather than product questions, which suggests the constraint isn’t appetite, it’s knowing what’s already allowed.
What Bylaw 20001 allows
Zoning Bylaw 20001 came into effect on 1 January 2024, replacing Edmonton’s previous bylaw and consolidating dozens of residential zones into a handful.
The one that matters for most homeowners is the RS — Small Scale Residential zone, intended to allow a range of small-scale residential development up to three storeys in height, including detached, attached and multi-unit housing.
What it permits:
| Value | |
|---|---|
| Maximum dwellings, interior (mid-block) lot | 8 |
| Site area required per dwelling | roughly 75 m² |
| Lot size to reach 8 units | about 600 m² |
| More than 8 units | corner sites only |
| Maximum height | 10.5 m (three storeys) |
| Maximum site coverage | 45% |
Design requirements apply alongside: a minimum 15% window area on the front facade, a main entrance facing the street, a covered entrance feature, two or more design techniques on street-facing facades and side walls, and 30% of the site in soft landscaping with a tree and shrubs per primary dwelling.
The practical significance: a standard Edmonton residential lot can often accommodate several units without a rezoning. No council decision, no public hearing — a development permit and a building permit.
Garage suites and garden suites in Edmonton
Rear-yard units are now regulated under a single category: Backyard Housing, defined as a building containing one or more dwellings located wholly within the rear yard. This replaces what the City previously called garage suites and garden suites.
Under Section 6.10 Backyard Housing:
| Regulation | Value |
|---|---|
| Maximum height | 6.8 m |
| Maximum height where rear lot line abuts a residential site limited to 12.0 m or less | 4.3 m |
| Maximum site coverage | 20% |
| Maximum second storey floor area per dwelling | 60.0 m² |
| With Inclusive Design (s. 5.50) | 70.0 m² |
| Minimum setback | 1.2 m |
| Minimum rear setback abutting an alley, no garage door facing | 0.6 m |
| Minimum distance to other principal buildings | 3.0 m |
Two things commonly reported wrongly:
The 60 m² caps the second storey, not the whole unit. It’s frequently quoted as a total floor area limit, which understates what’s permitted — particularly for a garage suite, where the ground level is the garage and the 60 m² governs the living space above it.
Backyard housing cannot be subdivided. The bylaw states plainly that it must not be subdivided from the other principal dwellings on the site, or form part of a bare land condominium. If you were hoping to sell the rear unit separately, that’s settled.
Also required: a main entrance separate from any garage door, plus a covered entrance feature. Our garage suite guide covers that product specifically.
The permit path
Two approvals, in sequence:
1. Development permit. Confirms the proposal complies with the zoning bylaw — use, height, site coverage, floor area, setbacks, landscaping and design requirements. This is where the numbers above are checked.
2. Building permit. Confirms construction meets the National Building Code – Alberta Edition — structure, egress, fire separation, insulation. Electrical and plumbing permits are separate, and generally require licensed trades.
Practical notes specific to Edmonton:
- Check your zone first. Edmonton’s mapping tools let you look up your property’s zoning designation before spending anything. The City also publishes open data that is queryable by address — worth using before you commission drawings.
- Confirm your height limit. The reduction from 6.8 m to 4.3 m where the rear lot line abuts a lower-height residential site is easy to miss and can rule out a two-storey backyard design entirely.
- Decide on Inclusive Design early. The difference between a 60 m² and a 70 m² second storey is a design decision made at the drawing stage, not a variance you request later.
Our Edmonton building guide covers the process in detail.
What it costs in Edmonton
We don’t publish a construction figure — the range between converting existing basement space and building a new backyard structure is too wide for one number to be useful.
But the cost base in Edmonton is genuinely different, and this is the part worth understanding:
No provincial sales tax. British Columbia charges 7% PST on many construction inputs. Alberta charges none. On a build where materials are a large share of cost, that difference is substantial and applies automatically — no application, no eligibility test, no waitlist.
No Ontario-style development charges. Ontario municipalities levy development charges per residential unit, and across the GTA they’re among the highest in the country — which is precisely why Ontario’s Bill 23 exemption on second and third units is so valuable there. Edmonton homeowners simply don’t face the equivalent per-unit charge on an infill suite. Municipal permit and inspection fees still apply, so confirm the City’s current schedule.
Put together: an Edmonton homeowner adding a unit starts from a materially lower cost base than an equivalent Ontario or B.C. owner, before any programme is considered. Nobody announces this, which is why it’s underrated — but it’s larger and more reliable than any grant.
What still drives Edmonton cost: servicing distance to the rear yard, foundation and soil conditions, the build season, and whether an existing garage can carry a suite above it (usually the slab and footings can’t).
What support actually exists
Stated accurately, because this is routinely misreported:
Edmonton has no municipal suite grant. The City’s secondary suites page covers zoning and definitions with no funding programme attached. Older “Cornerstones” material still circulates online but relates to a much earlier bylaw era.
Alberta’s SHARP is not a suite programme. The Seniors Home Adaptation and Repair Program is a low-interest home equity loan of up to $40,000 for Alberta seniors — income of $75,000 or less, minimum 25% home equity — to repair or adapt their own primary residence. Building a rental suite is not among its stated purposes.
Alberta’s RAMP is not a suite programme either. The Residential Access Modification Program provides accessibility grants of up to $12,000 per person per benefit year and $24,000 per person over 10 years, for lower-income Albertans who use a wheelchair, or seniors 65+ using a four-wheel walker, or people with listed progressive conditions. Strict income thresholds apply. It funds modifications to your own living space.
The federal $80,000 loan was cancelled and never launched.
What does apply: CMHC’s refinance product — up to 90% of as-improved value on properties with up to four units — and the MHRTC where the occupant is a qualifying relative. Our financing and grants guide covers the current position.
Where to start
- Look up your zoning. Use the City’s mapping tool or open data to confirm your zone and site area — that determines your unit ceiling.
- Measure your lot. Site area divided by roughly 75 m² gives you a rough maximum; setbacks and coverage will reduce it.
- Check your rear lot line’s neighbouring height limit, if you’re considering backyard housing.
- Establish servicing. How far water, sewer and power have to travel is frequently the largest single cost item on a rear-yard build.

Find out what your Edmonton lot already permits
Most Edmonton homeowners underestimate their own zoning. What decides your number is site area, whether you’re mid-block or on a corner, and your rear lot line’s neighbouring height limit — all checkable before you spend anything.
