The short version
Any detached garage over about 10 m² (~108 sq ft) in Red Deer needs two permits: a Development Permit (zoning compliance) and a Building Permit (structural compliance with the Alberta Building Code). If you’re running power to it, you also need an Electrical Permit. The City reviews lot coverage, setbacks, height, and structural details. Most reviews take 2–4 weeks; the build itself takes 4–8 weeks of active work.
Permits you’ll need
1. Development Permit
Confirms zoning compliance: setbacks, lot coverage, height, parking implications. Required for any accessory building over the size threshold.
2. Building Permit
Reviewed for compliance with the Alberta Building Code. Requires drawings showing foundation type, framing details, wall and roof assemblies, and any structural calculations for larger spans.
3. Electrical Permit (if running power)
Required for any electrical run to the garage — from a basic 240V welder outlet to a fully-finished subpanel with lighting, outlets, and heat. Pulled by a certified electrician.
4. Gas Permit (if adding heat)
Only if you’re running a gas line to a garage heater. Pulled by a licensed gas fitter.
Setback, height, and lot coverage rules
Setbacks (typical for residential zones)
- • Side yard: typically 0.6m (2 ft) minimum, larger if openings face that yard
- • Rear yard: typically 0.6m (2 ft) minimum
- • Front yard: detached garages are usually not permitted in front-yard placement
- • From principal dwelling: typically 1.2m (4 ft) minimum
- • From other accessory buildings: typically 1.2m (4 ft) minimum
Setback minimums vary by exact zone. Corner lots and irregular lots may have additional requirements. Always verify with the City.
Maximum height
Typically around 5.5m (~18 ft) measured from average grade to the peak of the roof for accessory buildings in residential zones. Garage suites (with living space above) often have different height allowances. Verify your specific zoning.
Lot coverage
Most R-1 residential zones in Red Deer have a maximum total lot coverage (combined footprint of all buildings) of around 45–50% of the lot area. Your house already takes up part of that. We help you confirm a proposed garage size fits within what’s left.
Maximum size of an accessory building
Many zones cap accessory building size at a percentage of the lot or as a hard maximum. Garages much larger than a typical double-bay (around 65–75 m²) may require a Discretionary Use approval.

Common mistakes
- Starting before permits are issued. The City can issue a stop-work order and require demolition.
- Underestimating setbacks. A proposed location that looks fine on paper may not survive the actual measurement.
- Exceeding lot coverage. The house plus garage plus shed plus deck can hit the cap quickly.
- Skipping the Electrical Permit because 'it's just one outlet.' Code enforcement catches these, especially at home sale.
- Building taller than the height limit and not realizing until the roof is on. Measure from average grade to peak before you frame.
- Forgetting about drainage. Garages can re-route water onto neighbors' lots — the City reviews this.
