Garages, sheds, pergolas, gazebos, greenhouses, arbours, workshops, playhouses and carports​.

We’re here to help guide you through your home improvement project. By completing the home improvement application, we can assist you by:

  • Determining what permit types you require
  • Offering solutions or alternatives
  • Processing your application
  • Transitioning you smoothly through the application process

Do I need a permit?

Typically you do NOT need a permit, if what you’re building:

  • Is under 10 m2 (107 sq. ft.).
  • Is 1 m (3'-3") or further from the house (if your project is attached to the house, see additions).
  • Is not in the front yard.
  • Meets the height restrictions

If your garage or related project falls outside of any of the above specifications, you will require a permit.

Visit understanding permits and the review process​​ to find out more about the permitting process.

How do I make an application?

Step 1: Open the application form & checklist

Use the home improvement application as a starting point, to determine the specific requirements for your project.

Step 2: Prepare your drawings

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

Step 3: Apply

Submit the application once you have provided all the documents required. Use our fee calculator to estimate how much your permit will cost.

Building code and bylaw information

Note: It is the responsibility of the applicant to ensure that the work being carried out conforms to any restrictive covenants, caveats or other restrictions that are registered on the land title and meets all rules and guidelines of the Land Use Bylaw and Alberta Building Code.​

Illustrations of codes and bylaw​s

Sample drawings for building permits and development permits for detached garages and sheds.

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

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

Example:

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 d​​iagram:

Eave distance from property line
Eave distance from property line

Height

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.

Parking

Number of ​stalls required

Most properties require one parking space per dwelling unit, unless your property falls into one of the categori​es 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 stal​ls 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 yo​ur 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.

Driveway

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 i​nformation on additional parking required for secondary suites, visit Calgary.ca/suites.

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​

Additional inquiries about building, plumbing, gas, electrical or heating, ventilation and air conditioning code or construction methods, building safety and fire regulations, please contact the Technical Assistance Centre or call 311. For all other inquiries (i.e. Land Use Bylaw), please contact our Planning Services Centre.

Inspection information

All inspections for residential construction, electrical, plumbing and gas fireplace installation permits can be booked at calgary.ca/311online. When choosing the service type, scroll down to Inspection and choose your project. You will need to provide your permit number or address.

Generally, your project will require a rough-in and a final inspection for each building and trade permit pulled, though additional inspections may be required. You can contact 311 on the morning of your inspection to find out if it will be in the morning or afternoon.

The inspection process is dynamic and an inspection outcome depends on the chosen construction method and site conditions at time of inspection. The information provided is not intended as an exhaustive list but a generalized outline of the inspection process.

Inspections for building permits

In most cases, and at the inspector’s discretion, only a rough-in inspection is required.

Rough-in inspection requirements

  • Complete concrete slab.
  • Install and complete all the wall and ceiling framing.
  • Install proposed windows and exterior doors.
  • Exterior finishes can be installed. Do not install interior finishes.
  • Rough-in, install and complete all plumbing and electrical components that are required under associated permits.
  • Have requested documentation on site.

Inspections for electrical permits

Rough-in inspection requirements

  • Provide access to the house to confirm breakers are installed in the house panel.
  • Have all wiring and interior of boxes readily visible.
  • Do not secure devices (plugs, switches) to boxes. Leave all wiring and terminations visible. Devices do not need to be installed for the rough inspection.
  • Remove vapour barriers and insulation where it’s covering any wiring. The exception is for wiring fished into walls.
  • Terminate all wiring into boxes and fixtures and remove outer jackets. Ensure all splices are made and all grounding is complete and visible in outlet boxes.
  • All wiring must be supported.
  • Cables may be terminated into the panelboard, but should not be on breakers.
  • Rough and underground inspections should be combined. Expose the trench on at least one end to confirm depth.
  • Install breakers and terminate wires.
  • Never energize exposed wiring.

Final inspection requirements

  • Do not have any exposed live wiring.
  • Ensure all outlets, light fixtures and cover plates are in place.
  • Energize all branch circuits for inspection.
  • Complete the panelboard breaker directory.

A permit services report will be mailed to the owner after an acceptable inspection.

Note: Although preferred, it is not necessary to have the wallboard installed for a final inspection.

A development completion permit inspection may be required if a development permit is involved in your project. Contact the Planning Services Centre to determine if a development completion permit is required.
