Calgary Fence Permit Site Plan: Corner Lots, Gates and Visibility
A residential fence can improve privacy, contain pets, control backyard access and define the edge of a property. On a Calgary corner lot, though, the fence design must also preserve clear views through the intersection for drivers, cyclists and pedestrians.
A clear Calgary fence permit site plan shows the proposed fence and gates in relation to the legal property boundaries, existing house, curbs, sidewalks, streets and corner visibility triangle.
Most ordinary residential fences do not require a building permit. A planning approval, known as a development permit, is generally required when the fence or gate exceeds the Land Use Bylaw limits or does not satisfy the corner visibility rules.[1]
Preparing the site plan before construction helps identify visibility, height, encroachment and property-line problems before posts are installed.

Does a Residential Fence Require a Permit in Calgary?
In most situations, a compliant residential fence does not require a building permit or development permit.
The City says planning approval is typically required when a fence:
- is higher than 2.0 m in the rear yard;
- is higher than 1.2 m in the front yard;
- is higher than 0.75 m inside a corner visibility triangle; or
- has a gate higher than 2.5 m.[1]
A development permit may also be needed where:
- the proposed fence conflicts with the applicable land-use district;
- a relaxation from the normal height limit is requested;
- finished grades within the corner visibility triangle exceed the permitted elevation;
- an unusual gateway or decorative entrance feature is proposed;
- a direct-control district contains different fence rules; or
- a previous development approval controls the fence design.
Planning Approval Versus Building Approval
A fence-height relaxation is generally handled as a development permit, which is a planning approval.
A standard residential fence does not normally require building-safety approval because it is not treated as a habitable building.
A separate building permit may become relevant where the project also includes:
- a retaining wall retaining 1.2 m or more of soil;
- multiple retaining walls whose combined height triggers approval;
- structural features outside ordinary fence construction;
- a swimming pool or hot tub enclosure;
- a deck, building or another permit-regulated structure; or
- work affecting public infrastructure.
The City’s project page distinguishes a fence relaxation from the building-permit requirements that can apply to retaining walls.[1]
Important Corrections to the Featured Image
The featured image is an educational illustration. It is not a legal survey, approved development permit or property-specific interpretation of Calgary’s Land Use Bylaw.
Change the visibility triangle from 6 m to 7.5 m
The image shows a triangular area measuring six metres along each side of the corner.
Calgary’s Land Use Bylaw defines a corner visibility triangle as the area formed by:
- the two curb lines at the street intersection; and
- a diagonal line intersecting both curb lines 7.5 m from the point where the curb lines meet.[3]
The image should therefore replace the three six-metre labels with a diagram based on the two curb lines and 7.5-metre measurements.
Change the obstruction height from 1.0 m to 0.75 m
Within a corner visibility triangle on a typical low-density residential parcel, buildings, fences, finished grade and vegetation must not rise more than 0.75 m above the lowest street elevation.[4]
Replace the yellow image callout with:
“Within the corner visibility triangle, buildings, fences, finished grade and vegetation must not exceed 0.75 m above the lowest street elevation.”
Correct the front-fence height
The image shows a maximum front-street fence height of one metre within six metres of the property line.
For typical low-density residential development, the general maximum is:
- 1.2 m for the portion of fence between the foremost front façade of the main residential building and the front property line; and
- 2.0 m in other locations, subject to the corner visibility requirement.[2]
There is no general six-metre-wide front-yard strip using a one-metre fence maximum.
Correct the side-street fence note
The image also shows a one-metre side-street fence limit within six metres of the property line.
That is not the general Calgary low-density residential rule.
A side-street fence may generally be up to two metres high when:
- it is not within the portion regulated by the front-façade rule;
- it remains outside the corner visibility triangle;
- the property’s district does not contain a different rule; and
- it remains on private property.
The complete corner and building layout must be shown before the permissible height can be confirmed.
Remove “gates must open inward only”
The City sources reviewed do not establish a blanket rule requiring every residential gate to swing inward.
A safer image note is:
“Show the gate swing or sliding direction and keep all gate movement within private property. Do not obstruct a sidewalk, boulevard, road or other public right-of-way.”
An inward-opening gate is often a practical way to achieve this, but it should not be presented as a universal gate rule.
Correct the gateway rule
A normal fence may generally be up to two metres high outside the front-fence and visibility restrictions.
The Land Use Bylaw allows up to 2.5 m at the highest point of a gate when the gate is no more than 2.5 m in length.[2]
A wider gateway does not automatically receive the 2.5-metre height allowance.
Correct the bylaw name
The image refers to “Fence By-law 20M88.”
Bylaw 20M88 is Calgary’s Street Bylaw, not a standalone Fence By-law. Residential fence height and corner visibility rules are contained primarily in Land Use Bylaw 1P2007.
What Is a Calgary Fence Site Plan?
A fence site plan is a scaled, overhead drawing of the property and the proposed fence.
It should show enough information for the owner, installer and City reviewer to determine:
- where the legal boundaries are located;
- which portions of the fence are in the front, side and rear areas;
- how high each fence section will be;
- where the gates will be installed;
- whether the property is a corner parcel;
- where the curb lines and visibility triangle are located;
- whether the fence enters City land or an easement; and
- whether trees, vegetation or grade changes affect visibility.
What Must a Fence Permit Site Plan Show?
Calgary’s current fence-permit checklist requires the site plan to include:
- the property address;
- property lines;
- the fence location;
- fence height and materials; and
- the outline of the house and other buildings on the parcel.[5]
A detailed corner-lot plan should go further and show the following.
Property information
- complete municipal address;
- legal lot, block and plan description;
- all property boundaries and dimensions;
- both street names;
- street and lane frontages;
- north arrow;
- drawing scale;
- land-use district;
- survey or Real Property Report source; and
- drawing date and revision number.
Existing site features
- existing house;
- attached and detached garages;
- sheds and accessory buildings;
- decks and patios;
- driveways and parking pads;
- existing fence sections;
- retaining walls;
- public sidewalks;
- boulevards;
- curb lines;
- public and private trees;
- hedges and shrubs near the corner;
- utility boxes, hydrants and poles;
- surface-drainage facilities; and
- registered easements and rights-of-way.
Proposed fence information
- complete proposed fence alignment;
- height of each fence section;
- fence materials;
- solid or open construction;
- post and decorative-column locations;
- pedestrian-gate location;
- vehicle-gate location;
- actual gate width;
- gate height;
- gate swing or sliding direction;
- distance from the fence to each legal boundary;
- distance from the fence to sidewalks and curbs;
- the 7.5-metre corner visibility triangle;
- sections requiring a height relaxation; and
- areas where utility or maintenance access must remain available.
What Should the Fence Elevation Show?
The City’s fence checklist also requires an elevation drawing showing:
- the property address;
- grade;
- height from the ground to the highest fence point; and
- finish materials.[5]
The elevation should identify:
- post height;
- panel height;
- gate height;
- decorative arch or gateway height;
- lattice or privacy-top height;
- retaining-wall height;
- finished grade on both sides; and
- changes in height along sloping ground.
Calgary Residential Fence Height Rules
| Fence location or feature | Typical low-density residential maximum |
|---|---|
| Between the foremost front façade and front property line | 1.2 m |
| Side or rear location outside the front-fence and visibility restrictions | 2.0 m |
| Inside a corner visibility triangle | 0.75 m above the lowest street elevation |
| Highest point of a qualifying gate | 2.5 m when the gate is no more than 2.5 m long |
These are general rules from the low-density residential provisions. Multi-residential, mixed-use, commercial, industrial and direct-control districts may use different wording or standards.
How Is Fence Height Measured?
Calgary measures fence height from grade to the highest point of the fence.[1]
The measurement can become complicated where the fence is installed:
- on sloping ground;
- on top of a retaining wall;
- beside a raised planter;
- beside a sunken patio;
- beside a driveway ramp;
- on recently added fill; or
- between properties with different ground elevations.
The site plan and elevation should show both existing and proposed grades where a level change affects the measured fence height.
What Is a Calgary Corner Parcel?
The Land Use Bylaw defines a corner parcel as a parcel adjoining two streets that intersect at an angle no greater than 135 degrees.[3]
A corner parcel generally has:
- a front property line;
- a street-side property line;
- an interior side property line; and
- a rear property line.
The corner visibility triangle is separate from these yard classifications. It is drawn from the curb lines at the street intersection.
How the Corner Visibility Triangle Is Drawn
To draw Calgary’s general corner visibility triangle:
- identify the point where the two curb lines meet;
- measure 7.5 m along the first curb line;
- measure 7.5 m along the second curb line;
- draw a straight diagonal between the two measured points; and
- identify the triangular area enclosed by the curb lines and diagonal.
The triangle may extend across:
- the boulevard;
- the public sidewalk;
- part of the private corner yard; and
- land that does not align neatly with the property boundaries.
This is why a site plan should show the actual curb lines—not only the legal lot boundaries.
What Must Remain Low Inside the Triangle?
The low-density residential visibility rule applies to:
- buildings;
- fences;
- finished property grade; and
- vegetation.[4]
Possible obstructions include:
- solid fence panels;
- stone or masonry columns;
- gate posts;
- hedges;
- shrubs;
- low tree branches;
- raised planters;
- retaining walls;
- mailboxes;
- signs;
- stored waste bins; and
- snow piles.
A compliant low fence can still create a visibility problem if dense shrubs are planted immediately behind it.
Why the Image’s Six-Metre Triangle Is Misleading
Six metres appears frequently in driveway and parking requirements, but it is not Calgary’s general corner visibility-triangle dimension.
For the corner visibility triangle, the current general definition uses:
- curb lines; and
- 7.5-metre measurements.
Using property lines and six-metre measurements can produce a triangle that is substantially different from the area regulated by the Land Use Bylaw.
Front-Yard Fence Placement
The lower 1.2-metre fence limit applies to the portion of fence extending between:
- the home’s foremost front façade; and
- the front property line.
The site plan should therefore show:
- the legal front property line;
- the foremost front façade;
- porches and projections;
- the proposed fence alignment;
- the proposed fence height; and
- the location of any front gate.
The front-fence restriction is based on the relationship between the fence and the house façade—not a universal six-metre distance from the street.
Street-Side Fence on a Corner Lot
A side fence facing the secondary street may often reach two metres outside the corner visibility triangle, but the full layout must be reviewed.
Factors include:
- the location of the home’s foremost front façade;
- the legal front property line;
- the street-side boundary;
- the 7.5-metre corner visibility triangle;
- driveway access;
- public sidewalks;
- utility rights-of-way;
- public trees;
- developer fencing; and
- property-specific land-use rules.
A site plan should not simply label the first six metres of the street side as a one-metre fence zone.
Pedestrian Gates
The general Land Use Bylaw provisions reviewed do not establish one universal minimum pedestrian-gate width.
The site plan should show:
- actual clear opening width;
- gate height;
- hinge side;
- swing or sliding direction;
- walkway width;
- distance from the sidewalk;
- steps or grade changes;
- nearby vegetation; and
- whether it forms part of a pool enclosure.
A gate should be positioned so it can operate without extending into a public sidewalk, boulevard, street or other City interest.
Vehicle Gates
A vehicle gate should be coordinated with the legal driveway and curb crossing.
The plan should show:
- actual gate width;
- gate height;
- single-, double- or sliding-gate configuration;
- direction of movement;
- driveway width;
- curb-crossing width;
- distance from the sidewalk;
- vehicle waiting space;
- intersection visibility;
- public trees and utility poles; and
- the complete visibility triangle.
A gate does not authorize:
- a new driveway;
- a wider curb crossing;
- paving across the boulevard;
- sidewalk reconstruction; or
- vehicle access through City land.
Driveway and public-crossing approvals must be reviewed separately.
Gateway Height and Length
A decorative gateway may rise to 2.5 m at its highest point only when the gate is no more than 2.5 m in length.[2]
The plan and elevation should distinguish between:
- the moving gate leaf;
- stationary fence panels;
- gate posts;
- an overhead arch;
- decorative caps; and
- the overall gateway length.
A broad vehicle entrance with tall columns or an overhead arch may require a development permit even when the adjacent fence is compliant.
Does a Gate Have to Open Inward?
The City sources reviewed do not identify a universal inward-only requirement for ordinary residential gates.
However, an outward-swinging gate can create problems when it:
- crosses the property boundary;
- projects over a public sidewalk;
- enters a boulevard or street;
- blocks pedestrian travel;
- interferes with a neighbouring driveway; or
- reduces corner visibility.
Showing the gate opening inward on the site plan is often the simplest way to demonstrate that it remains within private property.
Fences and Legal Property Boundaries
Do not assume that the existing fence is located on the legal boundary.
A fence can be:
- inside the subject property;
- inside the neighbouring property;
- offset from the boundary;
- built around a tree or retaining wall;
- located partly on City land; or
- affected by an encroachment agreement.
Useful boundary information may come from:
- a current Real Property Report;
- a registered legal plan;
- verified survey monuments;
- a previous approved site plan; or
- measurements completed by an Alberta land surveyor.
Read Site Plan vs Survey in Canada: What’s the Difference for Permits? before installing a fence close to an uncertain boundary.
Using a Real Property Report
A Real Property Report can help identify:
- legal property boundaries;
- existing improvements;
- registered rights-of-way;
- encroachments;
- house and garage locations;
- retaining walls; and
- surveyed dimensions.
The proposed fence and gates can be added to a copy of the RPR to form the base of a site plan.
A Certificate of Compliance confirms whether buildings and structures shown on an RPR comply with relevant Land Use Bylaw location requirements. It does not automatically approve separate encroachments into City land or easements.[10]
Shared Property-Line Fences
Where a fence permit application places the fence on a shared property line, Calgary’s checklist requires a letter of authorization from both property owners.[5]
Before building a shared fence, neighbours should agree on:
- the legal boundary location;
- fence height;
- materials;
- finished appearance;
- gate locations;
- contractor;
- cost sharing;
- maintenance; and
- future replacement.
The City’s planning approval does not settle a private disagreement about ownership, construction cost or boundary location.
Do Not Build Onto City Property
Calgary says new fence construction is not permitted to extend onto City property.[1]
City property can include:
- road rights-of-way;
- boulevards;
- public sidewalks;
- lanes;
- parks;
- reserve lands;
- City parcels; and
- certain utility interests.
An encroachment exists when a fence or another private structure extends from privately owned land into City land or an interest held by the City.[7]
An existing encroachment may require:
- removal;
- an encroachment consent letter;
- an encroachment agreement;
- a licence of occupation; or
- another City authorization.
Approval is not guaranteed, particularly on reserve land.
Sidewalk, Boulevard and Property Line Are Different
The visible edge of a front lawn is not necessarily the property boundary.
The road right-of-way can include:
- the street;
- curb and gutter;
- boulevard;
- sidewalk;
- street trees;
- streetlights;
- hydrants; and
- underground utilities.[11]
The private property line may be behind the sidewalk or within an area that appears to form part of the homeowner’s lawn.
Utility Rights-of-Way
A utility right-of-way is an easement over private property that allows the City or utility providers to install, access and maintain infrastructure.
A site plan should identify known rights-of-way containing or protecting:
- water services;
- sanitary sewer;
- stormwater infrastructure;
- gas lines;
- electrical cables;
- telecommunication facilities; and
- other utilities.
A fence may sometimes cross a utility right-of-way, but it must not prevent access or violate the registered easement terms. Removable sections or gates may be required.
Utility Locates Before Digging
Fence-post excavation can damage gas, electric, water and communication infrastructure.
The City directs owners to contact Utility Safety Partners before digging.[9]
Public locate requests may identify lines owned by participating operators. They may not identify privately installed services such as:
- electrical wiring to a garage or shed;
- landscape-lighting cables;
- irrigation systems;
- gas lines to a barbecue or pool heater;
- private drainage pipes;
- security wiring; or
- privately installed telecommunications.
A private utility locator may be needed for those services.
Public Trees Near the Fence
The fence-permit checklist requires a Public Tree Disclosure Statement.[5]
Calgary’s public-tree form says a Tree Protection Plan is required where construction activity occurs within six metres of a public tree. Public trees must be shown on the submitted plans.[8]
Fence work can damage trees through:
- post-hole excavation;
- root cutting;
- soil compaction;
- material storage;
- vehicle access;
- grade changes;
- attachment of materials to the trunk; and
- unapproved pruning.
A tree beside the sidewalk or boulevard may be City property even when it appears to be part of the front yard.
Hedges and Vegetation at Corners
The visibility restriction includes vegetation.
Homeowners should maintain:
- hedges;
- shrubs;
- bushes;
- ornamental grasses; and
- low tree branches
so they do not exceed the applicable 0.75-metre corner visibility limit.
A low open fence does not solve the visibility problem if a dense hedge later blocks the view through the corner.
Fence on Top of a Retaining Wall
A fence beside or on top of a retaining wall should be shown in elevation.
The drawing should identify:
- existing grade;
- retained grade;
- retaining-wall height;
- fence height;
- combined visual height;
- distance to the property line;
- drainage behind the wall; and
- whether a guard is required.
A retaining wall retaining 1.2 m or more of soil normally requires a building permit. Closely spaced retaining walls can also be evaluated using their combined height.[1]
The fence and wall should not be presented as one simple two-metre fence when the finished structure creates a much taller edge beside a neighbour, sidewalk or street.
Drainage Beside a Fence
A fence should not obstruct a surface-drainage facility or redirect runoff onto neighbouring property.
Potential problems include:
- solid fence boards trapping water;
- concrete post footings blocking a swale;
- soil piled against the fence;
- raised planters altering grade;
- snow storage blocking drainage;
- water ponding beside the house; and
- runoff freezing across a sidewalk.
The plan may show:
- surface-flow arrows;
- swales;
- catch basins;
- retaining walls;
- finished-grade changes;
- downspouts; and
- overland drainage rights-of-way.
Developer Fences and Restrictive Covenants
Some Calgary communities have fences installed by a developer along:
- major roads;
- parks;
- pathways;
- community boundaries; or
- multiple residential lots.
The City says a restrictive covenant is often registered on title for a developer fence and may establish the owner’s maintenance responsibilities and alteration rights.[1]
Before removing, modifying or attaching a private fence to a developer fence, review:
- the property title;
- registered caveats;
- architectural controls;
- community association rules;
- maintenance obligations; and
- City ownership information.
Pool Fences and Gates
A pool enclosure follows separate building-code safety requirements.
Calgary’s pool guidance requires an outdoor swimming pool to be protected by a qualifying fence, building wall, enclosure or approved safety cover. A private-pool fence generally requires a minimum height of 1.8 m.[12]
A pool gate must satisfy additional requirements, including:
- appropriate height;
- self-closing operation;
- secure latching;
- protection against unauthorized access; and
- compliance with the applicable building code.
Do not use an ordinary yard-gate detail for a swimming-pool enclosure without confirming the current pool requirements.
What Is Needed for a Fence Development-Permit Application?
The City’s current checklist requires:
- a completed Site Contamination Statement;
- a completed Public Tree Disclosure Statement;
- one site plan;
- one fence elevation; and
- authorization from both property owners when the fence is placed on a shared property line.[5]
The Development Authority may request additional information.
Depending on the property, this can include:
- a Real Property Report;
- title and registered instruments;
- corner visibility calculations;
- curb-line dimensions;
- retaining-wall details;
- tree-protection information;
- photographs;
- neighbour authorization;
- encroachment documentation; and
- revised drawings.
Typical Calgary Fence Planning Process
- Confirm the legal property boundaries.
- Check the property’s current land-use district.
- Identify the foremost front façade of the house.
- Identify the front, side, rear and street-side boundaries.
- Locate the two curb lines at the street intersection.
- Draw the 7.5-metre corner visibility triangle.
- Keep fences, grades and vegetation inside the triangle below 0.75 m.
- Select the height for each fence section.
- Position pedestrian and vehicle gates.
- Show gate movement entirely within private property.
- Check City property, rights-of-way and easements.
- Identify public trees and drainage features.
- Prepare the scaled site plan and fence elevation.
- Determine whether a development permit is required.
- Obtain neighbour authorization for a shared-line permit application.
- Submit the application where required.
- Request utility locates before digging.
- Construct the fence according to the approved or compliant layout.
Common Calgary Fence Site Plan Mistakes
- Showing a six-metre corner visibility triangle instead of 7.5 metres.
- Measuring the triangle from property lines rather than curb lines.
- Using one metre as the corner obstruction limit instead of 0.75 m.
- Using one metre as the normal front-fence maximum instead of 1.2 m.
- Applying a six-metre one-metre-high strip along the side street.
- Failing to show the foremost front façade of the house.
- Showing every gate as subject to an inward-only rule.
- Failing to show the gate swing or sliding direction.
- Using the 2.5-metre gateway allowance for a gate longer than 2.5 m.
- Measuring from an existing fence instead of the legal boundary.
- Leaving sidewalks, boulevards and curbs off the drawing.
- Building a fence on City property.
- Ignoring a utility right-of-way.
- Leaving public trees off the permit plan.
- Failing to account for hedges and vegetation inside the visibility triangle.
- Ignoring retaining-wall and grade changes.
- Blocking a drainage swale.
- Modifying a developer fence without reviewing the title covenant.
- Using ordinary gate details for a pool enclosure.
- Digging fence-post holes before obtaining utility locates.

Calgary Fence Site Plan FAQs
Does a normal residential fence require a permit?
Usually not. A development permit is generally required when the fence, gate or corner condition does not meet the Land Use Bylaw.
What is the maximum front-fence height?
The general low-density residential maximum is 1.2 m between the home’s foremost front façade and the front property line.
What is the maximum side- or rear-fence height?
The general maximum is 2.0 m outside the front-fence and corner visibility restrictions.
How large is Calgary’s corner visibility triangle?
The general definition uses two curb lines and a diagonal intersecting both curb lines 7.5 m from the corner where they meet.
Is the triangle measured from the property lines?
No. Calgary’s general definition uses curb lines.
Is the six-metre triangle shown in the image correct?
No. It should be replaced by the City’s general 7.5-metre curb-line triangle.
How high can a fence be inside the visibility triangle?
Buildings, fences, finished grade and vegetation generally cannot rise more than 0.75 m above the lowest street elevation.
Is the one-metre visibility limit in the image correct?
No. The general Calgary low-density residential limit is 0.75 m.
Can a side-street fence be two metres high?
Potentially, where it is outside the corner visibility triangle and does not fall within another restricted fence area. The property’s district and complete layout must be reviewed.
Does a gate have to open inward?
The City sources reviewed do not establish a universal inward-only rule for ordinary residential gates. The gate should remain within private property and avoid obstructing public space.
How high can a gate be?
The highest point may generally reach 2.5 m when the gate is no more than 2.5 m long.
Can a wide vehicle gate also be 2.5 metres high?
Not automatically. The special 2.5-metre height provision applies only when the gate is no longer than 2.5 m.
Can a gate swing over the sidewalk?
It should be designed to operate within private property and not obstruct or encroach into the public sidewalk, boulevard or street.
Can the fence be built on the shared property line?
Potentially, but the boundary should be verified. A fence permit application placing the fence on a shared line requires authorization from both property owners.
Can I rely on the existing fence as the legal boundary?
No. Existing fences are sometimes offset or located partly outside the legal property.
Can I build the fence to the sidewalk?
Only when the legal property extends to that location and all visibility and encroachment requirements are satisfied. The sidewalk and boulevard are often within City right-of-way.
Do I need to show curb lines?
Yes, on a corner lot. Calgary’s corner visibility triangle is based on curb lines.
Do trees and hedges count as visibility obstructions?
Yes. Vegetation is expressly included in the low-density residential visibility rule.
Do public trees need to be shown?
Yes, for a fence permit application. Construction within six metres of a public tree can require a Tree Protection Plan.
Can the fence cross a utility right-of-way?
Possibly, but it must comply with the registered easement and preserve utility access. Property-specific confirmation may be needed.
Do I need utility locates?
Yes. Utility Safety Partners should be contacted before fence-post excavation.
Does a fence on a retaining wall use the same simple height rule?
The fence and wall should be shown in elevation. Retaining-wall permits, grade changes and the combined visual condition may require additional review.
Does a pool fence follow these same rules?
Pool enclosures have additional building-code safety requirements, including greater minimum height and regulated gate operation.
What drawings are needed for a fence relaxation?
The City requires a site plan and elevation, together with the applicable forms and supporting information.
Can the plan be revised after City comments?
Yes. It can be updated using corrected survey information, curb measurements, revised heights, gate details, tree requirements or City review comments.
