Summary
A sourced walkthrough of City of Saskatoon basement development permits: when you need one, secondary suites vs rec rooms, drawings, bedroom windows, asbestos forms, and TSASK electrical.
Finishing a Saskatoon basement is a permitted construction project, not a cosmetic weekend. The City publishes the checklist. Use it.
Do you need a building permit to finish a basement?
Yes. The City of Saskatoon building permits page lists basement developments, secondary suites, and fireplaces among projects that require a building permit.
The same page lists purely cosmetic work — painting, patching drywall, laying carpet, and similar minor finish repairs — as common projects that do not require a building permit when that is the entire scope. As soon as you add walls, bedrooms, plumbing, or new wiring, you are out of that cosmetic list.
Rec room versus secondary suite
The City’s Basement Development Project Guide (PDF) applies to basement development in one-unit, two-unit, and multi-family dwellings. It states: if you are developing the basement as an additional dwelling unit, apply for a secondary suite permit.
That is a planning decision, not a wording trick. A family rec room and a rental suite are different applications.
What to submit
The renovation, addition, or new construction guide and the basement PDF together describe a complete basement file. Always required in the PDF:
- Submission Details Form
- Floor plans showing dimensions of the entire basement, labelled room uses, window location and size, unobstructed opening size, and window-well locations measured perpendicular from the well edge to the window
Other items the City says may be required:
- Site plan when adding or enlarging windows
- Elevation drawing (the PDF includes a sample)
- Engineered drawings for structural work outside Part 9 of the National Building Code, plus a structural commitment letter for field review
- Energy Efficiency Compliance Form for envelope, window, or mechanical alterations on houses built after 1 January 2019
- Spray foam insulation request form when using spray foam
- Asbestos Removal Notification Form for buildings constructed before 1990 (also listed on the renovation guide)
The renovation guide also lists structural drawings, building elevations, and a site plan among complete-application items for renovations and basement development. If your file is larger than a simple rec-room layout, budget time for a designer. The City suggests hiring one for larger projects.
Bedroom windows (from the City guide)
The basement guide states:
- Bedroom windows must have a minimum opening of 0.35 m² (3.8 ft²) with no dimension less than 380 mm (15 in)
- A clear path of 760 mm (30 in) is required between the building or window swing for an exit from a bedroom
- A window covered by a deck requires 760 mm (30 in) clearance between grade and the deck
Do not treat those as “close enough.” Plan the wall layout around them.
The Submission Details Form also asks whether exterior-wall framing, insulation, and vapour barrier were completed under the original building permit, and whether you are installing or enlarging windows.
Plumbing and electrical are separate
The renovation guide: a plumbing system cannot be constructed, extended, altered, renewed, or repaired without a plumbing permit. See the City’s plumbing project guide if you are adding a bathroom.
Electrical and gas permits are administered by TSASK, not Building Standards. Electrical permits in Saskatoon explains the homeowner-versus-contractor split. Rough-in inspection happens before drywall.
How to apply and what it costs
Apply through ePermitting. Building Standards: 306-975-2645, building.standards@saskatoon.ca.
Building permit fees are published by the City, including a 2026 per-square-foot rate for basement development or alteration of any floor area and a minimum fee. Read the City page for the current schedule.
How WLG Homes fits
Basement development in Saskatoon is framing and licensed electrical under one crew, with the City building permit submitted for work we are hired to do. Finishes (drywall, flooring, millwork) are scoped separately so the quote matches what we actually build.
For layout decisions before you apply, read planning a basement development in Saskatoon. For the construction sequence, see our earlier basement development overview.
This page summarizes City of Saskatoon and TSASK publications. It is not a permit, not legal advice, and not a substitute for the current guides. Contact WLG Homes for a free estimate, or use the planning check to gather notes first.
