Calgary accessory building site plan showing a proposed detached garage, existing house, rear lane, property boundaries, setbacks, driveway access, height and parcel coverage — Example Calgary accessory building site plan showing a proposed detached garage, existing dwelling, rear lane, property lines, setbacks, driveway access, landscaping and parcel-coverage calculations. The address, zoning, dimensions and calculations are illustrative and must be verified for the actual property.

Calgary Accessory Building Site Plan for Permit: Setbacks, Height and Lot Coverage

A detached garage, shed, workshop, gazebo or similar backyard structure can add useful parking, storage and covered outdoor space to a Calgary property. Before construction begins, however, the building must comply with the property’s land-use district, boundary setbacks, height limits, parcel coverage, parking requirements, drainage pattern and registered rights-of-way.

A clear Calgary accessory building site plan shows the proposed structure in relation to the legal property lines, existing house, rear lane, driveway, public trees, easements and drainage features.

The drawing can help the homeowner, contractor and City reviewer identify problems before concrete is poured or materials are ordered. Moving a garage on a drawing is considerably cheaper than moving a completed foundation.

What Is an Accessory Residential Building?

Under Calgary’s Land Use Bylaw, detached garages and several similar structures are classified as accessory residential buildings.^[1]

Examples include:

detached garages;
storage sheds;
workshops;
detached carports;
gazebos;
pergolas;
greenhouses;
arbours;
playhouses; and
other covered buildings that are detached from the house.

If the structure is physically attached to the house, it is generally treated as an addition rather than as a detached accessory residential building.

Does a Calgary Accessory Building Require a Permit?

A building permit is generally required when a detached accessory residential building is larger than 10 m².^[1]

The proposed garage illustrated in the featured image is larger than 10 m² and therefore requires building approval.

A structure of 10 m² or less may not require a building permit, but it must still comply with the Land Use Bylaw rules governing:

location;
setbacks;
height;
parcel coverage;
building separation;
roof drainage;
rights-of-way;
parking; and
permitted use.

Permit-exempt does not mean bylaw-exempt. A small shed can still require relocation or a development permit if it is placed in a prohibited area or fails another land-use rule.

Building Permit Versus Development Permit

A building permit and development permit serve different purposes.

Building permit

The building permit reviews construction safety under the applicable Alberta building code. It considers matters such as:

foundation and slab construction;
wall and roof framing;
fire protection near property lines;
structural beams and trusses;
doors and windows;
electrical work;
plumbing work; and
required inspections.

Development permit

A development permit may be required when:

the accessory residential building is discretionary in the applicable district;
the proposed setback does not comply;
the building is too close to the house;
the proposed height exceeds the bylaw maximum;
the eaveline is too high;
the building exceeds its permitted area;
total parcel coverage is exceeded;
a rooftop deck or balcony is proposed;
the structure is within the actual front setback; or
another Land Use Bylaw relaxation is requested.^[1]

A development permit requesting a relaxation is not guaranteed to be approved.

Important Corrections to the Featured Image

The featured image is an educational example. It is not a Real Property Report, legal survey, approved permit drawing or property-specific zoning interpretation.

Correct the garage dimensions or area

The proposed garage is labelled:

6.10 m × 7.32 m = 22.2 m².

That calculation is incorrect:

6.10 m × 7.32 m = approximately 44.7 m².

The image must therefore use one of these corrections:

keep the 6.10 m × 7.32 m dimensions and change the garage area to approximately 44.7 m²; or
keep the 22.2 m² area and replace the dimensions with measurements that multiply to approximately 22.2 m².

Correct the parcel-coverage calculation

The image contains two different coverage results:

32.1% in the site-statistics panel; and
35.4% in the coverage table.

Using the stated areas of 142 m² for the house and 22.2 m² for the garage:

(142 m² + 22.2 m²) ÷ 464.5 m² × 100 = approximately 35.4%.

If the illustrated garage dimensions of 6.10 m × 7.32 m are used, the calculation becomes:

(142 m² + 44.7 m²) ÷ 464.5 m² × 100 = approximately 40.2%.

Replace the 50% R-CG coverage label

The image identifies 50% as the maximum coverage for the example R-CG property.

The current R-CG rules use a density-based system:

45% where density is below 40 units per hectare;
50% where density is at least 40 but below 50 units per hectare; and
55% where density is at least 50 units per hectare.^[3]

A single dwelling on the illustrated 464.5 m² parcel represents approximately 21.5 units per hectare. Its general starting limit would therefore be 45%, not 50%.

The maximum may also be reduced when required motor-vehicle parking is provided outside a private garage.

Correct the accessory-building size limit

The image says the maximum accessory-building area is the lesser of:

10% of the lot area; or
90 m².

That is not Calgary’s general rule.

The combined coverage of accessory residential buildings generally must not exceed the lesser of:

the building coverage of the main residential building; or
75 m² for each dwelling unit located on the parcel.^[2]

For the illustrated property, the house footprint is stated as 142 m². For a property containing one dwelling unit, the accessory-building maximum would therefore generally be 75 m², subject to parcel coverage and all other rules.

Correct the side-yard setbacks

The image shows 1.22 m as the minimum on both interior sides.

Calgary’s general accessory-building rule is:

1.2 m from a side or rear property line shared with a street; and
0.6 m from a side or rear property line in other cases.^[2]

The side boundaries in the featured image appear to adjoin neighbouring residential properties rather than streets. The general setback is therefore 0.6 m, not 1.22 m.

The rear setback is approximately correct

The image’s 0.61 m rear setback closely represents Calgary’s 0.6 m general requirement.

Where the garage door faces a rear lane, the garage apron must also generally provide 0.6 m between the rear property line and the garage door.^[1]

Remove the universal 4.57 m front setback

An accessory residential building is not permitted within the property’s actual front setback area.^[2]

The actual front setback is property-specific. It is not represented by one universal 4.57 m accessory-building setback.

Replace the image label with:

“Accessory building must remain outside the actual front setback—verify for the property.”

Correct the building height

The image shows a 4.57 m maximum. Calgary expresses the general maximum as 4.6 m, measured from the finished floor to the highest point of the building.^[1]

The image should also show:

maximum height to roof peak: 4.6 m;
maximum eaveline height: 3.0 m;
maximum one storey; and
restricted attic configuration.

Add the house-to-building separation

An accessory residential building of at least 10 m² generally requires at least 1.0 m between its closest façade and the main residential building.^[2]

The site plan should add a clear dimension between the proposed garage and the house, including any relevant cantilevers, bay windows or other projections.

Remove the universal driveway-setback label

The image shows a 1.52 m driveway setback from the front property line. This is not a universal Calgary accessory-building rule.

The plan should instead show:

the actual driveway dimensions;
which driveway serves the garage;
the garage apron at the lane;
parking-stall dimensions;
the public sidewalk and curb; and
any separate driveway approval affecting the property.

Calgary Accessory Building Setbacks

Location or condition	General rule
Side or rear property line shared with another private parcel	0.6 m
Side or rear property line shared with a street	1.2 m
Garage door facing a lane	Generally 0.6 m apron between the rear property line and garage door
Accessory building of at least 10 m² to the house	1.0 m between the closest façades
Actual front setback area	Accessory residential building not permitted

These are general rules. Zero-lot-line properties, street-side corner boundaries, rights-of-way, historical approvals and site-specific land-use districts can produce a different result.

Can the Building Be Placed on the Property Line?

In certain cases, a non-street side or rear setback can be reduced to zero.

The Land Use Bylaw provides possible zero-setback options when:

the accessory building is less than 10 m²;
the building wall uses maintenance-free materials and no eave projects onto the adjoining parcel; or
the adjoining owner grants and registers the required private maintenance and encroachment easements.^[2]

The complete design must also ensure that:

roof water remains on the subject property;
footings do not cross the property boundary;
eaves comply with building-code clearances;
fire protection is provided where required;
the wall can be maintained lawfully; and
no utility right-of-way is obstructed.

A homeowner should not assume that maintenance-free siding alone permits construction on the property line without a complete City review.

How Close Can the Building Be to the House?

A minimum separation of 1.0 m generally applies between a main residential building and an accessory building of at least 10 m².

The measurement is taken between the closest façades and can be affected by:

bay windows;
cantilevers;
chimneys;
attached decks;
roof overhangs;
steps and landings;
air-conditioning equipment; and
other building projections.

A proposed building closer than 1.0 m normally requires a development permit relaxation and may trigger additional building-code requirements.

Accessory Building Height

Calgary’s general height limits for an accessory residential building are:

maximum 4.6 m from the finished floor to the highest building point;
maximum 3.0 m from the finished floor to the highest eaveline;
maximum one storey; and
an attic only when it complies with the specific storage restrictions.^[1]

Attic restrictions

A permitted attic must:

have no windows;
be accessed by a removable ladder;
be used only for household storage; and
have no more than 1.5 m from the attic floor to the underside of a rafter.

A fixed stair, bedroom-style window or habitable room can cause the design to be treated differently and require redesign or additional approvals.

How Is Height Measured?

The image says height is measured from average grade. That is not the correct general measurement for the accessory-building limit shown.

Calgary’s rule measures:

the overall 4.6 m height from the finished floor to the highest point; and
the 3.0 m eaveline height from the finished floor to the intersection of the wall and roof structure.

The elevations and cross-section should show:

existing grade;
finished grade;
finished floor elevation;
wall height;
eaveline height;
roof slope;
roof peak; and
attic dimensions where applicable.

Maximum Accessory Building Area

Calgary uses two different tests when determining whether a proposed garage or accessory building is too large.

Test 1: accessory-building coverage

The combined area of the accessory residential buildings generally cannot exceed the lesser of:

the footprint of the main residential building; or
75 m² for each dwelling unit on the parcel.^[2]

Accessory buildings with a cumulative area of 10 m² or less are excluded from this accessory-building coverage calculation.

Test 2: total parcel coverage

The main house, qualifying accessory buildings and other covered structures must also remain within the maximum parcel coverage allowed by the property’s land-use district.

Passing one test does not guarantee that the other is satisfied.

R-CG Parcel Coverage

The example image assumes an R-CG property. Accessory Residential Building is a permitted use in R-CG, but the complete development must comply with both the district rules and the general low-density residential rules.^[3]

Current R-CG maximum coverage is based on density:

Development density	General maximum coverage
Less than 40 units per hectare	45%
At least 40 but less than 50 units per hectare	50%
50 units per hectare or more	55%

The maximum is reduced when required parking stalls are not located in a private garage:

21 m² where one required stall is located outside a garage; or
19 m² for each required outdoor stall when more than one stall is required.

Corrected Coverage Example for the Featured Image

The sample lot area is 464.5 m².

Option A: keep the stated garage area

existing dwelling: 142.0 m²;
proposed garage: 22.2 m²;
total building coverage: 164.2 m²; and
parcel coverage: approximately 35.4%.

Option B: keep the stated garage dimensions

existing dwelling: 142.0 m²;
6.10 m × 7.32 m garage: approximately 44.7 m²;
total building coverage: approximately 186.7 m²; and
parcel coverage: approximately 40.2%.

Both examples are below 45%, but the final result must also consider:

all other accessory buildings;
covered decks and porches;
parking-area reductions;
the actual dwelling count and density;
previous approvals;
the legal parcel area; and
the property’s current land-use designation.

What Counts Toward Parcel Coverage?

Parcel coverage generally includes the footprints of qualifying buildings and covered structures.

The calculation may need to include:

the house;
attached garages;
detached garages;
sheds larger than the applicable exclusion;
covered decks;
covered patios;
gazebos;
pergolas with qualifying roof coverage;
greenhouses; and
other roofed accessory buildings.

The City’s garage guidance says an uncovered deck is not included in its example coverage calculation, while a roofed deck is included.^[1]

The site plan should provide a line-by-line breakdown rather than displaying only the final percentage.

Rear-Lane Garage Access

The image places the proposed garage beside a rear lane.

A permit-ready site plan should show:

the legal rear property line;
lane width;
garage-door position;
the 0.6 m garage apron;
driveway or apron width;
lane grade;
garage floor elevation;
utility poles and overhead lines;
catch basins and drainage channels;
fences and gates; and
vehicle manoeuvring space.

Where a garage accesses an unpaved lane, the City offers an optional lane-grade service to help establish an appropriate garage-floor elevation.^[1]

Parking Stall Dimensions

The garage and site plan must provide the required parking in usable dimensions.

Calgary’s current residential garage guidance gives these minimum parking-stall dimensions:

5.9 m × 3.0 m where the stall touches two barriers;
5.9 m × 2.85 m where it touches one barrier; and
5.9 m × 2.5 m where it touches no barriers.^[1]

Garage walls, fences and property lines are treated as barriers for this measurement.

The interior garage dimensions—not merely its exterior footprint—must be large enough to accommodate the intended parking stalls.

What Should the Site Plan Show?

The City says an applicant may modify a Real Property Report to use as the site plan. The plan must identify the proposed building’s location, size, height and distances from the property lines and house.^[1]

Property information

complete Calgary address;
legal lot, block and plan information;
current land-use district;
property boundaries and dimensions;
parcel area;
street and lane names;
north arrow;
drawing scale; and
drawing date and revision number.

Existing buildings and improvements

existing house footprint;
attached garage;
existing detached garages and sheds;
covered decks and porches;
uncovered decks and patios;
driveways and parking pads;
sidewalks and curbs;
retaining walls;
fences and gates; and
public and private trees.

Proposed building

overall exterior dimensions;
building footprint;
intended use;
finished-floor elevation;
overall height;
eaveline height;
roof shape and slope;
garage-door location;
pedestrian-door and window locations;
setbacks to all relevant property lines;
distance to the house;
garage apron;
vehicle-access route;
roof-drainage direction; and
construction-access area.

Can a Real Property Report Be Used?

Yes. Calgary says an existing Real Property Report may be modified to form the base of an accessory-building site plan.^[1]

An RPR can help establish:

legal property boundaries;
existing building locations;
registered easements;
rights-of-way;
encroachments;
existing improvements; and
surveyed dimensions.

The proposed building must be added clearly and dimensioned.

Read Site Plan vs Survey in Canada: What’s the Difference for Permits? before relying on an approximate online map for a garage close to a boundary.

Rights-of-Way and Easements

The property title and RPR should be reviewed for:

utility rights-of-way;
overland drainage rights-of-way;
maintenance-access rights-of-way;
access rights-of-way; and
other City or private easements.

Calgary states that permanent structures cannot be built in utility rights-of-way. Footings, walls and eaves are all parts of the building for this purpose.^[1]

Overland drainage rights-of-way must remain free of:

buildings;
landscaping obstructions;
debris;
fill;
fences that block flow; and
other features that interfere with drainage.

If a maintenance-access right-of-way applies, the registered document may be required with the permit application.

Roof Drainage and Lot Grading

All roof drainage from an accessory residential building must discharge onto the parcel on which the building is located.^[2]

The building should not direct water:

onto neighbouring property;
into the rear lane in a way that creates icing;
toward the house foundation;
into the garage entrance;
against a retaining wall;
into a utility right-of-way; or
across a public sidewalk.

Calgary’s positive-lot-drainage guidance says surface water should move away from building foundations toward a street, lane or swale without adversely affecting neighbouring property or public infrastructure.^[4]

A detailed site plan may show:

existing and proposed grades;
garage slab elevation;
lane elevation;
surface-flow arrows;
swales;
roof gutters and downspouts;
retaining walls;
catch basins;
low points; and
the lawful drainage route.

Public Trees

A development-permit application may require a Public Tree Disclosure Statement.

The applicant must identify whether a public tree is:

on City land within six metres of the property; or
overhanging the property.^[6]

Where public trees are present, they should be shown on the site plan.

Construction can damage a tree through:

foundation excavation;
root cutting;
material storage;
soil compaction;
vehicle movement;
grade changes;
utility trenching; and
contact with branches or trunks.

Additional tree-protection plans and permits can be required where work affects City land or occurs close to a public tree.

Utility Locates Before Excavation

Buried utilities should be located before excavation begins.

Utility Safety Partners provides Alberta’s Click Before You Dig notification service. Homeowners can request markings for participating buried utility operators before excavation.^[8]

Possible underground services include:

gas;
electricity;
water;
sanitary sewer;
storm sewer;
telecommunications; and
other utility infrastructure.

Privately installed lines may not be covered by the public locate service. These can include:

power to an existing shed;
yard-lighting cables;
irrigation pipes;
gas lines to a barbecue;
private drainage pipes; and
security wiring.

Fire Protection Near a Property Line

Building close to a property line can trigger fire-resistance and eave restrictions.

Calgary’s current guidance says that accessory residential buildings of at least 10 m² located within 0.6 m of a side property line can require:

5/8-inch Type X drywall on the affected interior wall;
restrictions on eave projections;
non-vented soffits in specified locations;
control of wall openings; and
roof drainage retained on the subject property.^[1]

The permit drawings should identify the actual distance to the property line and provide the required construction details.

Foundation and Slab Design

The foundation design depends on:

garage size;
soil conditions;
building loads;
masonry or veneer construction;
retaining walls;
grade changes;
vehicle loads;
frost protection; and
the proposed heating system.

Calgary says a garage slab larger than 55 m² may require professional engineering when it does not have a concrete foundation extending 1.2 m below grade.^[1]

Engineering may also be required for:

unusual foundations;
poor or filled soils;
significant retaining walls;
large roof spans;
non-standard framing;
heavy storage loads; or
construction close to another foundation.

Other Permit Drawings

The site plan is only one part of a complete application.

Depending on the project, the City may also require:

floor plan;
foundation or slab plan;
roof-framing plan;
elevations of all four sides;
building cross-section;
wall and roof construction details;
beam calculations;
manufacturer’s truss layouts;
engineering drawings;
maintenance-access right-of-way documents;
abandoned-well declaration;
public-tree disclosure; and
other property-specific supporting documents.^[1]

Electrical, Plumbing and Gas Permits

A separate electrical permit is required for new electrical installations.

For a new garage, electrical work can include:

lighting;
receptacles;
garage-door opener;
electric heating;
workshop circuits;
exterior lighting;
electric-vehicle charging; and
underground or overhead supply wiring.

A plumbing permit is required for new plumbing or for extensions and alterations to an existing plumbing system.

A gas permit may be required for a gas heater or new gas piping.

The person completing each regulated trade must obtain the correct permit and arrange the associated inspection.

Accessory Buildings Cannot Be Used as Unapproved Housing

An ordinary accessory residential building cannot be used as a dwelling unit unless a Backyard Suite has been approved.^[2]

A standard detached garage, shed or workshop should not be used as:

a bedroom;
a rental suite;
a separate apartment;
a permanent sleeping cabin; or
an unapproved backyard home.

A legal backyard suite follows a different planning, building, servicing, parking and design process.

An ordinary accessory residential building also cannot have a rooftop deck or balcony.

Building Inspections

Calgary’s homeowner inspection guidance says a garage inspection can generally occur at the framing stage or when construction is complete.

The garage must normally be at lock-up stage, meaning:

doors are installed;
windows are installed;
the building is secure;
the site is safe;
required fire-rated materials are installed; and
required electrical rough-ins are ready for inspection.^[5]

The permit conditions and inspector determine whether additional inspections are required.

Common Calgary Accessory Building Site Plan Mistakes

Using dimensions that do not match the stated building area.
Providing two different parcel-coverage percentages.
Using 50% as the maximum for every R-CG property.
Using 10% of lot area or 90 m² as the accessory-building maximum.
Showing 1.22 m as the ordinary interior side-yard setback.
Applying a universal 4.57 m front setback.
Measuring height from average grade instead of the finished floor.
Leaving the 3.0 m eaveline limit off the elevations.
Failing to show the 1.0 m house-to-building separation.
Measuring from a fence instead of the legal property line.
Failing to show the 0.6 m garage apron beside the lane.
Leaving an existing shed out of the accessory-building total.
Leaving a roofed deck out of parcel coverage.
Ignoring outdoor-parking reductions to maximum coverage.
Building over a utility right-of-way.
Blocking an overland drainage right-of-way.
Directing roof water onto neighbouring property.
Failing to show public trees.
Starting excavation before obtaining utility locates.
Beginning construction before the permit is issued.

Calgary Accessory Building FAQs

Does a detached garage require a building permit?

Yes. A detached garage larger than 10 m² requires a building permit.

Does a small shed under 10 m² require a permit?

It typically does not require a building permit, but it must still comply with zoning, setback, height, coverage, drainage and right-of-way rules.

What is the normal rear setback?

The general rear setback is 0.6 m when the boundary adjoins a lane or another private property.

What is the normal interior side setback?

The general setback from an interior side boundary shared with another property is 0.6 m.

When does a 1.2 m setback apply?

It applies where the accessory building’s side or rear property line is shared with a street.

Can a garage be built on the property line?

Potentially, when the applicable zero-setback conditions are met. Maintenance-free materials, eave restrictions, drainage and registered easements may be involved.

How far must the garage be from the house?

An accessory building of at least 10 m² generally requires one metre between its closest façade and the house.

Can the building be located in the front yard?

It cannot be located within the actual front setback area.

Is the front setback always 4.57 m?

No. The actual front setback is property-specific.

What is the maximum height?

The general maximum is 4.6 m from the finished floor to the highest point.

What is the maximum eaveline height?

The maximum is generally 3.0 m from the finished floor.

Can the garage have a second storey?

No. An ordinary accessory residential building is generally limited to one storey, although a restricted storage attic is permitted.

Can the garage have a rooftop deck?

No. An ordinary accessory residential building cannot have a rooftop deck or balcony. A proposal containing one requires different approval and is not guaranteed to be accepted.

What is the maximum accessory-building area?

The combined area is generally limited to the lesser of the main residential building’s footprint or 75 m² per dwelling unit.

Is the maximum always 10% of the lot?

No. The 10% rule shown in the image is incorrect for Calgary’s general accessory-building provisions.

What is the maximum R-CG parcel coverage?

It depends on development density. It is generally 45%, 50% or 55%, with possible reductions for required parking located outside a private garage.

What coverage applies to the illustrated single-house example?

A single dwelling on the illustrated 464.5 m² lot is below 40 units per hectare, so the general starting point is 45%.

Is the image’s 32.1% coverage calculation correct?

No. Using the image’s stated 22.2 m² garage area gives approximately 35.4%. Using its stated garage dimensions gives approximately 40.2%.

Does an uncovered deck count toward parcel coverage?

The City’s garage guidance excludes uncovered decks from its example calculation. A covered deck is included.

How much apron is needed between a lane and garage door?

The general minimum is 0.6 m from the lane-side property line to the garage door.

Can the garage be built over a utility right-of-way?

No. Permanent structures, including footings, walls and eaves, are not permitted in utility rights-of-way.

Where must roof water drain?

All roof drainage must remain on the subject parcel and should follow the approved positive-lot-drainage pattern.

Can the building be used as a bedroom or rental suite?

No. Residential occupation requires approval as a legal Backyard Suite or another permitted residential use.

Can an existing RPR be used as the site plan?

Yes. Calgary says an RPR can be modified to show the proposed building and required dimensions.

Can the plan be revised after City comments?

Yes. The site plan can be updated using corrected survey measurements, revised dimensions, zoning comments, grading information or a redesigned building.

Official Sources

Calgary’s land-use, permit, parking and parcel-coverage rules can change. Individual properties may also be affected by site-specific districts, development permits, zero-lot-line plans, rights-of-way, restrictive covenants, flood regulations, public trees and previous relaxations. Confirm current property-specific requirements with the City of Calgary before construction begins.
