What to Include on a Site Plan for a Building Permit in Canada

A site plan is one of the first documents municipalities review when assessing a building permit application in Canada.

Before a reviewer looks at framing, elevations, or construction details, they usually start with the site plan.

That is because the site plan shows how your project fits on the property — and whether it appears to comply with the most important zoning and permit requirements before deeper review begins.

At siteplans.ca, one of the most common reasons we see permit applications delayed is simple: the site plan is missing information the municipality expects to see immediately.

In many situations, the project itself is completely acceptable — but the site plan does not clearly show enough detail for municipal reviewers to continue review efficiently.

Municipal reviewers are usually trying to quickly confirm:

• where the project is located on the lot,
• how close it sits to property lines,
• whether setbacks appear compliant,
• how the proposed work affects the overall property layout,
• whether existing structures are shown clearly,
• whether the drawing is organized clearly enough to review quickly.

This guide explains exactly what to include on a site plan for a building permit in Canada, why each item matters, and how to make sure your submission is clear enough to avoid unnecessary delays.

Why the Site Plan Matters So Much

For most residential permits in Canada, the site plan is one of the first things municipal reviewers check.

Before municipalities assess engineering details, structural notes, or framing information, they usually want to confirm a few practical things first:

• where the project is located on the property,
• how close it is to property lines,
• whether setbacks appear compliant,
• how the proposed work relates to existing structures,
• whether the site layout is organized clearly enough to review.

That means your site plan often determines how smoothly the permit process moves from the very beginning.

If the site plan is clear and complete, review usually moves faster.

If key details are missing, permit review often slows down immediately with correction requests or revision notices.

Municipal reviewers commonly use the site plan as the main visual reference during early permit review because it quickly explains zoning, spacing, setbacks, access, and overall project placement before deeper technical review begins.

helps reviewers understand the project quickly and reduces avoidable back-and-forth during the application process.

1. Property Lines and Lot Dimensions

Every site plan should clearly show the full property boundary.

This is one of the first things municipalities use to understand the lot and verify whether the project fits within it properly.

Your site plan should clearly show:

• all property lines,
• lot width,
• lot depth,
• overall lot dimensions,
• the complete lot shape.

Without this information, municipalities cannot properly assess setbacks, lot coverage, or project placement.

If the property lines are unclear or incomplete, permit review often slows down immediately because nearly every zoning decision depends on accurate lot information.

2. North Arrow

A north arrow is a standard requirement on most site plans submitted for permit review in Canada.

It helps municipalities understand how the property is oriented relative to the street and surrounding properties.

This allows reviewers to better understand:

• site orientation,
• frontage location,
• property access,
• overall lot layout.

Although it is a small detail, it is one of the standard checklist items municipalities expect to see on a complete permit-ready site plan.

Without a north arrow, the site plan becomes more difficult to interpret during review.

3. Street Name and Frontage

Your site plan should clearly identify the street the property fronts onto.

This helps municipalities understand:

• site access,
• front lot line location,
• frontage orientation,
• relationship to the public roadway.

This section of the site plan should commonly include:

• street name,
• front lot line,
• driveway connection to the street,
• basic frontage layout.

Street frontage also helps municipalities understand how the project relates to neighbouring lots and overall site circulation.

4. Existing Structures

A complete site plan should show all major structures already existing on the property.

Municipal reviewers need to understand the existing site condition before they can properly evaluate the proposed work.

This commonly includes:

• existing house footprint,
• garage,
• shed,
• deck,
• pool,
• driveway,
• patio or hardscape areas,
• fence where relevant,
• other visible site structures.

Even if these structures are not changing, municipalities often still need to see them because they affect:

• lot organization,
• spacing between structures,
• setback review,
• lot coverage evaluation,
• how the proposed work fits on the property.

Municipal reviewers commonly compare the proposed work against the existing site condition during early permit review.

5. Proposed Structure or New Work

The proposed work must be clearly shown and clearly labeled.

This is the main reason the municipality is reviewing the site plan in the first place.

Whether you are building:

• a deck,
• a shed,
• a garage,
• a pool,
• a home addition,
• a driveway extension,
• a patio or pergola,

the proposed work should be immediately obvious on the drawing.

Municipal reviewers should not need to guess what is new and what already exists.

The proposed structure should stand out clearly from the rest of the site layout.

Reviewers are usually trying to quickly understand how the proposed project changes the property layout and whether the proposal appears reviewable under local zoning rules.

If the proposed work is not clearly labeled, the municipality may request clarification before continuing review.

6. Setback Dimensions

Setbacks are one of the most important things municipalities check on a site plan.

A setback is the required distance between a structure and the property line.

Most municipalities use setbacks to determine whether the proposed structure appears compliant with local zoning requirements.

Your site plan should clearly show setback distances from the proposed structure to:

• front property line,
• rear property line,
• left side lot line,
• right side lot line.

This is one of the first things municipal reviewers usually verify and one of the most common reasons site plans get sent back when missing.

Missing or inconsistent setbacks frequently delay permit approval across Canada.

7. Driveways and Access

Your site plan should show how the property is accessed.

This usually includes:

• driveways,
• walkways,
• parking access,
• pathways to the proposed structure where relevant.

This helps municipalities understand:

• site circulation,
• vehicle access,
• frontage layout,
• overall site functionality.

For garages, additions, detached structures, and larger residential projects, this becomes especially important during review.

Access-related details help municipalities evaluate whether the site still functions properly after the proposed work is completed.

8. Decks, Stairs, and Landings

If your project includes a deck, stairs, or landings, these elements should appear clearly on the site plan.

This is often overlooked on residential permit drawings.

Even when the deck platform itself is shown, stairs and landings are sometimes omitted even though they still affect:

• overall footprint,
• setbacks,
• site spacing,
• municipal review.

These features should be included wherever relevant because municipalities commonly review the full built footprint, not only the main structure itself.

Missing stairs or landings can create setback inconsistencies that delay permit approval later during review.

9. Accessory Structures

Accessory structures should be shown and labeled clearly on the site plan.

This commonly includes:

• sheds,
• detached garages,
• pool houses,
• cabins,
• gazebos,
• other detached structures.

These structures often affect:

• lot coverage,
• spacing between buildings,
• setback review,
• overall lot organization.

Even if these structures are not changing, municipalities often still need to see them because reviewers want a complete understanding of the property layout before approving additional construction.

10. Easements, Utilities, and Site Constraints

Some properties contain additional constraints that affect where building is allowed.

Where relevant, your site plan should show:

• easements,
• rights-of-way,
• utility corridors,
• septic systems,
• wells,
• drainage paths,
• slopes or retaining walls,
• restricted areas shown on municipal or property records.

These may not apply to every property, but when they do, they are important during municipal review.

If these constraints are relevant and missing from the site plan, municipalities may not be able to properly evaluate the proposed project.

These site conditions often determine where structures can legally or practically be placed on the property.

11. Scale and Drawing Clarity

A site plan should always be drawn to scale.

Most municipalities expect a scaled, legible drawing with:

• clear labels,
• consistent dimensions,
• organized spacing,
• readable linework,
• professional clarity.

A site plan can technically contain the correct information and still create delays if the layout is difficult to read.

Clarity matters just as much as completeness.

Municipal reviewers often review many applications each day, so organized drawings help speed up the permit review process significantly.

12. Project-Specific Details

Some permit applications require additional site plan details depending on the project type.

For example:

• Shed permits may require the proposed shed location, rear and side setbacks, slab or foundation location, and distance to existing structures.
• Deck permits may require deck dimensions, distance to lot lines, stairs, landings, and relationship to the house.
• Pool permits may require pool location, fencing, gates, equipment location, and distance to property lines.
• Garage permits may require driveway access, parking layout, garage footprint, and setbacks.
• Addition permits may require the addition footprint, connection to the existing house, lot coverage, and surrounding access.

Project-specific information helps reviewers understand the exact type of work being proposed and how it affects the property.

Why Complete Site Plans Help Permits Move Faster

Most permit delays happen because municipalities need more information before they can continue review confidently.

A complete site plan reduces those delays by helping municipalities quickly verify:

• project placement,
• setbacks,
• site layout,
• property access,
• zoning-related details.

The easier the drawing is to review, the easier it becomes for municipalities to move the application forward.

That is why complete, organized site plans often lead to faster review and fewer correction requests.
