A basement suite is legal in Saskatoon when the City has permitted it, inspected it, and issued an occupancy permit for it. Everything else is detail, and the detail is where most projects stall. This is the full 2026 checklist: what Zoning Bylaw 9990 allows on your lot, the ceiling heights and egress window sizes an inspector measures, the separate entrance rule that disqualifies more Saskatoon suites than anything else, fire separation, and the permits and fees you pay along the way. Get all of it right and the suite qualifies for up to $35,000 through the Secondary Suite Incentive Grant.

What a legal basement suite is in Saskatchewan
A legal basement suite in Saskatchewan is a self-contained dwelling unit inside a house, built under a City building permit, inspected at every stage, and issued an occupancy permit. Saskatoon's Zoning Bylaw 9990 calls it a secondary suite: accessory to and located within a one-unit dwelling or semi-detached dwelling.
Section 5.3.23 of the bylaw sets the limits. The suite cannot occupy more than 40% of the dwelling's gross floor area including the basement, and it cannot exceed 80 square metres. You get one suite per one-unit dwelling, or one per side of a semi-detached dwelling. A suite is not permitted in a one-unit or semi-detached dwelling that sits inside a dwelling group. The suite's floor area counts as part of the principal building, so it is not treated as a separate structure on the lot.
Bylaw 9990 took effect on January 3, 2025. Advice written before that date about discretionary approval for suites in residential zones is out of date for R1 and R2.
The 2026 requirements checklist
What are the requirements for a legal suite in Saskatoon?
A legal suite in Saskatoon needs a zoning-compliant lot, ceiling height of 2.0 m in living areas, an egress window in every bedroom, a separate exterior entrance, fire separation between the suite and the house, smoke detectors, building permits for both the suite and the entrance, and passing inspections through to occupancy.
| Requirement | Rule | Why it fails inspections |
|---|---|---|
| Zoning | Max 40% of gross floor area, max 80 m², one suite per dwelling or per side of a semi-detached | A suite over 80 m², or over 40% of the floor area, does not meet Bylaw 9990 |
| Ceiling height | 2.0 m in living areas, kitchens and bedrooms; 1.95 m in bathrooms and hallways | Measured height falls below the minimum in a room the suite depends on |
| Egress window | 0.35 m² clear opening, 380 mm minimum height and width, sill no higher than 1.0 m | Windows too small for emergency escape, one of the four common disqualifiers in Saskatoon |
| Window well | Large enough to access the window | The well is too small to reach or use the window |
| Separate entrance | Direct access outside, landing or porch, stairs with handrails, adequate lighting | Access runs through the main house. This is the most common disqualifier in Saskatoon |
| Fire separation | 5/8" Type X drywall ceiling and fire-rated doors | No fire separation between the suite and the main dwelling |
| Smoke detectors | Required | Detectors were never installed |
| Parking | One additional off-street space is typically required | The lot has nowhere to put the extra space |
| Engineering | Stamped drawings for any cut into the foundation | The City will not issue the entrance permit without them |
| Permits | Two building permits: one for the suite, one for the separate entrance | No building permits, another of the four common disqualifiers |
| Inspections | Framing, electrical rough-in (TSASK), plumbing rough-in, insulation, final | A phase was closed in before its inspection passed |
The same list, in the order the work happens:
- Your zone and lot allow a secondary suite under Bylaw 9990
- The suite stays under 80 square metres and under 40% of the dwelling's gross floor area
- One additional off-street parking space
- Ceiling height of 2.0 m in living areas, kitchens and bedrooms, 1.95 m in bathrooms and hallways
- An egress window in every bedroom with a clear opening of at least 0.35 square metres
- A window well large enough to access the window
- Stamped engineering drawings before any cut into the foundation
- A separate entrance with direct access outside, a landing, stairs with handrails and lighting
- 5/8" Type X drywall on the ceiling between the suite and the house, plus fire-rated doors
- Smoke detectors
- Two building permits, one for the suite and one for the entrance
- Framing, electrical, plumbing, insulation and final inspections all passed
- An occupancy permit from the City of Saskatoon
Zoning: is a suite allowed on your lot
Zoning is the first thing to settle, because it is the one requirement you cannot build your way out of.
Secondary suites are a permitted use in R1 and R2 zones. Under the previous bylaw, many zones needed discretionary approval. In R1 and R2 the suite is now permitted by right.
What the bylaw still controls is size and count. The suite cannot exceed 80 square metres or 40% of the dwelling's gross floor area including the basement. One suite per one-unit dwelling, or one per side of a semi-detached dwelling. A dwelling group rules the suite out entirely. One additional off-street parking space is typically required, which is the constraint that bites on narrow lots.
Check the zone before you pay for drawings. Our Saskatoon zoning checker takes an address and tells you the zone and what the bylaw allows there.
Ceiling height
Minimum 2.0 metres (6'6") in living areas, kitchens and bedrooms. Minimum 1.95 metres (6'5") in bathrooms and hallways. Beams and bulkheads can sit lower than that as long as they do not obstruct the main living area.
Ceiling height decides which rooms can go where, so measure before anyone draws a layout.
Egress windows and legal basement window size
Every bedroom in the suite needs an egress window for emergency escape. The numbers are specific, and an inspector measures them:
- Clear opening of at least 0.35 square metres (3.8 sq ft)
- Minimum height of 380 mm (15")
- Minimum width of 380 mm (15")
- Sill no more than 1.0 metre (39") above the floor
- A window well large enough to access the window
Inadequate egress, meaning windows too small to climb out of, is one of the four most common reasons a Saskatoon basement suite is not legal. Two or three egress windows cost $3,000 to $8,000.
Separate entrance
The suite needs direct access to the outside that does not pass through the main house, a landing or porch, proper stairs with handrails, and adequate lighting.
No separate entrance is the single most common reason a Saskatoon basement suite is not legal.
If the entrance requires a new opening in the foundation, a civil engineer has to produce stamped drawings first. The engineer works out the load paths and specifies the steel lintel and rebar. The City will not issue the permit without those drawings. Never cut a foundation without engineering approval.
Budget $5,000 to $15,000 for the separate entrance.
Fire separation and smoke detectors
The suite has to be separated from the main dwelling by a fire separation: 5/8" Type X drywall on the ceiling and fire-rated doors. Smoke detectors are required.
Missing fire separation is the fourth of the common disqualifiers, alongside no entrance, no permits and bad egress. Fire separation costs $2,000 to $5,000.
Permits, fees and inspections
How much does a building permit cost in Saskatoon?
A Saskatoon building permit for a basement suite runs $1,000 to $3,000 or more, calculated as a percentage of your declared construction value. Add $500 to $1,500 for plumbing and $300 to $800 for electrical permits and inspection fees. A development permit costs $236 to $443 if one is triggered.
| Fee | Amount | When it applies |
|---|---|---|
| Building permit | $1,000 - $3,000+ | Always. Calculated as a percentage of declared construction value |
| Plumbing permit | $500 - $1,500 | Always, for a suite with a kitchen and bathroom |
| Electrical permit and inspection | $300 - $800 | Always. Inspected through TSASK |
| Development permit | $236 - $443 | Only if discretionary approval or a footprint change is triggered |
| Legalizing Existing Suites (LES) permit | $2,250 | Legalizing an existing suite. As of January 2026, up from $1,750 in 2025 |
| Civil engineering, stamped drawings | $2,000 - $4,000 | Any cut into the foundation |
You pull two building permits, not one. The secondary suite permit covers the interior work: fire separation, egress, plumbing and electrical. The separate entrance permit covers the foundation cut, the exterior landing, the staircase and the drainage. For a conversion, budget $3,000 to $5,000 for the permit and engineering phase together.
The inspection sequence
Inspections run in order and each one has to pass before the next phase of work starts: framing, electrical rough-in through TSASK, plumbing rough-in, insulation, then the final inspection for occupancy. Without the occupancy permit at the end, the suite is not legal and it does not qualify for the SSI Grant.
Legal vs illegal: what you risk
What is the difference between a legal and illegal suite?
A legal suite has building permits, meets current code, passed City inspections, and holds an occupancy permit. An illegal or non-conforming suite is missing at least one of those. The gap shows up when you file an insurance claim, when a tenant is injured, or when you apply for the SSI Grant.
Renting a non-conforming suite carries real exposure. Your insurer may deny a claim or cancel the policy. You carry personal liability if a tenant or a visitor is injured. You cannot claim the SSI Grant. The city can fine you. And the suite pulls resale value down instead of adding to it.
Our guide on legal vs illegal basement suites goes through each of those risks in detail.
Legalizing an existing suite
If you already have a suite that was never permitted, the work is the same checklist, done in reverse. Start with what is missing. In Saskatoon that is usually the separate entrance, then permits, then egress and fire separation.
- Confirm the zone allows the suite and that it fits the 40% and 80 square metre limits.
- Have a civil engineer draw the foundation cut if the entrance is missing.
- Apply through the City's Legalizing Existing Suites stream. The LES permit fee is $2,250 as of January 2026, up from $1,750 in 2025.
- Build, and pass every inspection in the sequence.
- Get the occupancy permit, then apply for the SSI Grant.
A Stonebridge homeowner went through exactly this: foundation cut, new separate entrance, full interior buildout, 2.5 months from permits to occupancy, and the full $35,000 back. The Stonebridge conversion case study documents every phase with photos.
How the SSI Grant ties in
The Secondary Suite Incentive Grant pays 35% of eligible costs up to $35,000, including up to $5,000 for appliances. It applies only to a new legal secondary suite. Finishing a basement without creating a suite does not qualify. Renovating a suite that is already legal does not qualify. Converting a non-conforming suite that was never permitted does qualify.
Two deadlines govern it. Eligible costs must be incurred by March 31, 2027, and construction must be complete by December 31, 2027.
You apply to the Saskatchewan Ministry of Finance after you have the occupancy certificate. That is why the inspection sequence matters. No occupancy permit, no grant.
Run your own numbers with the SSI Grant calculator, and read the complete SSI Grant guide for the application details.
On cost: legal suite development in Saskatoon runs $65 to $120 per square foot, so a 700 sq ft suite lands around $45,500 to $84,000, with a premium build reaching about $131,000. Our basement development guide breaks that down by scope. Legal suites in Saskatoon rent for $1,000 to $1,400 a month. If you want the space without the suite, that is a different project under different rules, and it falls under our basement renovation and development services.

Book a free assessmentFrequently asked questions
Does a basement suite need a separate entrance in Saskatoon?
Yes. A legal secondary suite needs direct access to the outside that does not pass through the main house, with a landing or porch, stairs with handrails, and adequate lighting. No separate entrance is the most common reason Saskatoon suites are not legal. Adding one costs $5,000 to $15,000, and a foundation cut needs stamped engineering drawings before the City will permit it.
What size window does a basement bedroom need in Saskatchewan?
The egress window needs a clear opening of at least 0.35 square metres (3.8 sq ft), with a minimum height of 380 mm (15") and a minimum width of 380 mm (15"). The sill can be no more than 1.0 metre (39") above the floor, and the window well has to be large enough to access the window. Every bedroom in the suite needs one.
Can I legalize a basement suite that was built without permits?
Yes. The City of Saskatoon has a Legalizing Existing Suites stream, and the permit fee is $2,250 as of January 2026. The suite still has to meet every current requirement, so expect work on the entrance, egress and fire separation. A converted non-conforming suite qualifies for the SSI Grant, because the space was never permitted in the first place.
How long does a legal basement suite take to build?
About 8 to 12 weeks from permit approval. A Brighton suite we built was finished in two months. The Stonebridge conversion took 2.5 months from permits to occupancy, and that one included a foundation cut for a new entrance. Engineering and permit approval happen before that clock starts.
Do I need two permits for a basement suite in Saskatoon?
Yes, if you are adding a separate entrance. One building permit covers the suite itself: fire separation, egress, plumbing and electrical. The second covers the entrance, which means the foundation cut, the exterior landing, the staircase and the drainage. The City will not issue the entrance permit without stamped engineering drawings.
The Legalizing Existing Suites fee moved from $1,750 in 2025 to $2,250 in January 2026. The grant deadlines have not moved: eligible costs incurred by March 31, 2027, construction complete by December 31, 2027.
