A legal secondary suite in Edmonton can generate $1,200 to $2,000 per month in rental income while adding $50,000 to $100,000 to your home’s appraised value. It’s the highest-return renovation an Edmonton homeowner can make — but only if it’s built correctly and registered legally with the City of Edmonton.
At Art Edge Construction Ltd, we build legal basement suites from full-unfinished basement to completed, inspectable suite. We know Edmonton’s secondary suite requirements — ceiling heights, egress windows, independent heating, fire separation, and the permit process — and we build to pass every inspection the first time.
A City of Edmonton legal secondary suite must meet specific requirements. Here’s what we build into every suite:
Separate entrance: Either a side door or rear entrance — never through the main living area. Requires a landing, stair configuration to grade, and proper weather protection.
Minimum ceiling height: 1.95 metres (approximately 6’5″) in all habitable rooms. This is the most common issue in older Edmonton homes with low basement ceilings — we assess this at the site visit and confirm before you commit.
Egress windows in every bedroom: City of Edmonton requires that all basement bedrooms have windows large enough to exit through in an emergency. Minimum 0.35 m² of openable area with minimum 380mm height and 450mm width. We include egress window installation in our suite scope.
Independent heating: The suite must have its own heating system, not share the main home’s forced air without proper controls. We coordinate with mechanical trades for this requirement.
Fire separation: Walls and ceilings between the suite and the main dwelling must be 1-hour fire-rated assemblies using 5/8″ Type X drywall. We build this correctly every time.
Full kitchen: Cabinets, countertop, sink, and appliance rough-ins.
Full bathroom: Shower or tub, vanity, toilet — built to the same standard as our bathroom renovation service.
Development permit and building permit: Required for all legal suites in Edmonton. We advise you through the process and build to the drawings approved by the City.
Legal secondary suite development in Edmonton typically ranges from $60,000 to $95,000 for a full build-out of an existing unfinished basement.
What affects cost: existing ceiling height (low ceilings require more negotiation with the building department or aren’t feasible), number of bedrooms, egress window count, separate entrance complexity (rear entry through existing walkout versus new side entry cut into foundation), and finish level.
The investment is typically recovered through rental income in 4 to 7 years and adds significantly more in resale value than the development cost in most Edmonton markets.
We provide a written quote after a site assessment. Legal suite feasibility needs to be confirmed with a visit — we won’t quote a suite blind.
Step 1: Development permit application to City of Edmonton. This covers zoning approval for secondary suite use at your address. Processing time: 4 to 12 weeks.
Step 2: Building permit application. This covers the actual construction. Requires drawings to Alberta Building Code standards showing fire separation, egress, ceiling heights, and mechanical.
Step 3: Trade permits for electrical, plumbing, and gas/HVAC work. Required separately.
Step 4: Construction with inspections at key stages — framing, insulation, drywall before closing, final.
Step 5: Final inspection and occupancy approval.
We walk you through every step. We’ve done this process many times in Edmonton and can tell you exactly what to expect and when.
It depends primarily on ceiling height and zoning. Most residential zones in Edmonton allow secondary suites. Ceiling height under 1.95 metres is the most common disqualifier. We assess this at the site visit at no charge.
From permit application to occupancy approval: 4 to 7 months is typical, with the permit waiting period accounting for 1 to 3 months. Physical construction runs 8 to 14 weeks.
A legal suite has a development permit, building permit, and has passed all City of Edmonton inspections. It can be listed for rent legally, is covered by your home insurance (confirm with your insurer), and does not create liability for building code violations. An illegal suite carries risk of enforcement orders from the City, potential insurance coverage issues, and may affect resale.
Call 780-907-2949 or email artedgeconstruction@gmail.com to book a free site assessment. We walk the basement, confirm feasibility based on ceiling height and zoning, and provide a written quote within 48 hours. A legal suite done right pays for itself. We build them to pass every inspection and last for decades.
