Need help? Chat with us. We can help guide you through your home improvement project and assist you with:

  • Determining what permits you might require.
  • Offering solutions or alternatives.
  • Transitioning you smoothly through the application process.

When is a permit required?

Typically a garage or related structure does NOT need a permit when:

  • Is under 10 m2 (107 sq. ft.), and
  • It is not attached to a house (see additions), and
  • Is not in the front yard, and
  • It meets the height restrictions.

In most situations garages only require a building safety approval (building permit). If your design or location does not meet land use bylaw specifications you will also require planning approval (development permit).

How to apply

Step 1: Review the application checklist

Use the Garage permit checklist to determine the application and drawing requirements for your project.

Step 2: Prepare your application

To help you design your project, see the building code and City bylaw information section.

Note: if you are using engineered roof trusses, only a site plan is required.

Buildings under 10 m²

Accessory residential buildings under 10 m² in area typically do not require a building permit; however, the building must still follow the rules listed below to comply with the Land Use Bylaw.

Parcel coverage

Parcel coverage by all buildings cannot exceed a certain percentage of your total property size. This percentage is dictated by your specific land use district. To find out your land use district, please enter your address in the property information tool. See the graph below to determine your allowable lot coverage.

Land Use District Allowable Coverage (%) Parcel Area <= 300 m2
Parcel wdith < 10 m2
Parcel Area <= 300 m2
Parcel wdith < 8.7 m2
Parcel width > 11 m Semi-Detached / Duplex Row / Townhouse
40 x x x x x
45 x x x x x
R-C1N 45 50 x x x x
R-1N 50 x 60 45 x x
R-2 45 x x x 50 x
R-2M 45 x x x 50 60
*Parcel coverage rules for R-CG change as density increases.

Note: If the aggregate area of all accessory buildings is under 10 m2, those structures will not contribute to parcel coverage.

To calculate lot coverage, you will need to divide the footprint area of all applicable buildings by the property size.

(Total building area ÷ property area) × 100 = lot coverage per cent


Parcel coverage example
Parcel coverage example
  1. Use the property information tool and the graph above to figure out the allowable coverage for the property.
    R-C1 = 45%
  2. Calculate the property area.
    10.36 m × 32.0 m = 331.52 m2
  3. Add all applicable building areas:
    house: 77.2 m2
    covered deck*: 9.3 m2
    shed: 10.2 m2
    proposed garage: + 40.8 m2
    Total building area = 137.5 m2
  4. Divide the total building area by the property area and times that by 100 to get a percentage.
    total building area = 137.5 m2 × 100 = 41.47%
    property area = 331.52 m2

R-C1 allows for a maximum lot coverage of 45 per cent. Therefore, the proposal comes within the allowable lot coverage.

*Covered deck is only included in the calculation because it has a roof structure. Decks that are not covered should not be included.

Building setbacks

In most land use districts, the minimum building setback required is 0.6 m from a side or rear property line. When the side or rear property line is shared with a street, the garage must be 1.2 m from the property line. No accessory buildings may be located in the actual front setback on a low density residential property.

The building may go up to the side property line (as long as the property line is not shared with a street), as long as it meets all of the following requirements:

  • The exterior is maintenance-free (examples of maintenance-free materials include: vinyl and stucco) or the owner of the adjacent parcel grants a private maintenance easement.
  • All water drainage off of the building remains on the property.
  • The wall is fire rated with 5/8" type x drywall from floor slab to underside of roof sheathing to interior face of wall assemblies.
  • There is no eave overhang onto the adjacent lot.

The Alberta Building Code has specific distance requirements for eaves and soffits, as demonstrated in this diagram:

Eave distance from property line
Eave distance from property line


All accessory residential buildings must not exceed height requirements outlined in the Land Use Bylaw. The structure must:

  • Not be higher than 4.6 m from the finished floor.
  • Not be higher than 3.0 m (9'10") from the finished floor to the underside of the eaveline: the intersection of the wall and the roof structure at the highest point.
  • Be one storey in height, but can have an attic without windows, accessed by a removable ladder, used by the occupants of the house for storage. The attic is allowed to have maximum height of 1.5 m measured from the attic floor to the underside of any rafter.

Separation from the main residential building

All accessory residential buildings must have a 1.0 m separation from the main residential building or house. When measuring to determine the minimum separation distance between a proposed accessory residential building and the main residential building, measure from the closest wall of each building (include second floor cantilevers, bay windows, etc.).

Rooftop decks and balconies

Rooftop decks and balconies on accessory residential buildings are not permitted under the current Land Use Bylaw on accessory residential buildings without an approved development permit.

Semi-detached garages

Semi-detached garages straddle a property line. You will usually only see these when the house is a semi-detached dwelling. However, sometimes the owners of two single detached dwellings will build a semi-detached garage that straddles their common property line.

Two building permits are always required, whether the property has been subdivided or not. If the total garage area is over 75 m², a development permit is required.

Building near utility lines

Contact Alberta One-Call at 1-800-242-3447, to find out where your utility lines are before you build.

For information about building near or over gas lines, contact ATCO Gas at 403-245-7888.

If you have any questions regarding clearance from utility lines and boxes, contact ENMAX at 403-514-6100.

No structures are permitted to be built in a utility right-of-way.

Zero lot lines & maintenance access right-of-ways

Zero lot lines allow you to build up to your side property line. Zero lot lines commonly exist in conjunction with maintenance access right-of-ways on the opposite side of the lot and on adjacent lots. If your proposed structure projects into a maintenance access right-of-way, the document showing allowance for this type of construction must be presented at the time of application.

Lane grades

If a detached garage is accessing an unpaved rear lane, a lane grade can be established through a Development Site Servicing site visit. This will ensure that the garage floor will be at the correct elevation in relation to the lane. The City of Calgary will assume no responsibility for water runoff into the garage, or access problems arising from construction of a garage, due to a grade that is inconsistent with the design grade approved by Development Site Servicing. There is a fee for this service.

Number of stalls required

Most properties require one parking space per dwelling unit, unless your property falls into one of the categories below. If you are unsure of your land use district, please enter your address into the property information bar. If your land use district is not noted below, then you require one stall per dwelling.

Two stalls per dwelling are required when located in:

  • R-C1N or R-1N and the parcel width is less than 9 m.
  • R-C2 or R-2 and the parcel width is less than 9 m or the parcel area is less than 270 m2.

Two stalls per parcel are required when located in:

  • R-2M and the parcel width is less than 9 m or the parcel area is less than 270 m2.

If your property is an irregular shape and you are unsure of your parcel width, please refer to the example below to see how to measure your parcel width and determine how many parking stalls are required.


Parking requirements can be met with a parking pad, driveway or a garage. The required parking stalls must not be located one in front of the other.

Note: many properties in Calgary were developed prior to the current bylaw and its parking requirements. There is also the potential that relaxations for parking were granted on an individual property. In these cases, the current parking requirements may not have to be met.

For information on additional parking required for secondary suites, visit

Stall size requirements

For the purpose of parking stall requirements, walls of a garage, fences and property lines are considered barriers.

Parking stall size requirements:

  • If the parking stall abuts two barriers the stall must be at least 5.9 m x 3 m.
  • If the parking stall abuts only one barrier the stall must be 5.9 m x 2.85 m.
  • If the parking stall abuts no barriers the stall must be 5.9 m x 2.5 m.

Parking pad

Although a building permit is not required for a parking pad, if you plan on pouring a parking pad for the purpose of building a garage in the future you should consider the location after reviewing the previously listed Land Use Bylaw rules.

If your garage slab will have an area bigger than 55 square metres, and does not have a concrete foundation that is 1.2m below grade, you will need a concrete slab designed by a professional engineer. Please refer to Building Regulations Bulletin 2014-011.
