Detached Garage Planning Checklist
By Chad Ruppert
A practical checklist for planning a detached garage before ordering permit drawings or applying to the municipality.
Confirm the basics first
Before drawings begin, confirm the municipality, address, preferred garage size, door locations, lane access, roof style, and whether there are easements or rights-of-way on title.
Check placement before finalizing the design
Garage placement affects setbacks, lot coverage, eave projections, access, and review timing. The site plan should resolve these issues before construction starts.
Decide whether the project is standard or custom
A typical detached garage up to 592 sq ft is usually straightforward. Oversized garages, workshops, suites, and unusual lots should be quoted as custom projects.

Short answers to common garage permit questions.
Do I need a building permit for a detached garage?
Yes. In Calgary and most Alberta municipalities, a detached garage over 10 square meters requires a building permit before construction begins. The permit drawings show the garage location, size, setbacks, elevations, sections, and construction details for review.
What drawings are required for a detached garage permit?
A detached garage permit usually requires a site plan, floorplan, elevations, cross sections, and construction details. These drawings help the municipality confirm zoning, setbacks, height, lot placement, and building code compliance.
How much do standard garage permit drawings cost?
Standard garage permit drawings start at $695 for detached garages up to 592 square feet. Municipal application and building permit fees are separate and vary by city.
How fast can I get detached garage permit drawings?
Most standard detached garage drawing packages are completed in 2-3 days after the required project information is received. Custom garages, suites, workshops, and unusual sites may need a quoted timeline.
What if my garage is oversized or includes a suite?
Oversized garages, backyard suites, garage suites, and custom garage projects are quoted individually. These projects can require additional design coordination, foundation details, engineering, or deeper municipality review.
What happens if the permit reviewer asks for changes?
If the permit reviewer asks for clarification, the drawing set can be revised to respond to municipal review comments. Most comments involve setbacks, site information, construction notes, or missing details that need to be shown more clearly.
When does a detached garage need a development permit?
A development permit may be required when the garage does not meet land use bylaw rules for setbacks, height, lot coverage, placement, or other site conditions. Many standard detached garages only need a building permit, but the municipality decides based on the property and design.
