Plot Plan vs Survey Plan in Canada: Which One Do You Need?

If you are applying for a building permit, planning a home addition, buying a property, resolving a boundary question, or preparing drawings for a municipality, you may hear two similar terms: plot plan and survey plan. They sound similar, and both may show the property from above, but they are not the same thing.

In simple terms, a plot plan is usually used to show how a proposed project fits on a lot for permit or planning review. A survey plan is usually used to show accurate legal boundary and property information prepared by a licensed land surveyor.

Knowing the difference matters because submitting the wrong document can delay your permit, confuse your contractor, or create problems when exact boundaries are needed.

siteplans.ca prepares clear, professional site plans and plot plans for Canadian homeowners, builders, designers, and property professionals. If you need to show a proposed addition, deck, garage, shed, pool, porch, carport, driveway, or other project for permit review, a clean plot plan may be the right starting point.

Quick Answer: Plot Plan vs Survey Plan

A plot plan is usually the drawing you need when you are applying for a building permit and need to show the proposed work on your property.

A survey plan is usually needed when you need legal boundary accuracy, property-line confirmation, encroachment review, title-related information, or a municipality specifically asks for a survey.

Here is the easiest way to remember it:

• Plot plan: used for permits, planning, and showing proposed work.
• Survey plan: used for legal boundary accuracy and surveyor-certified property information.

The image above shows the difference clearly. The left side shows a permit-focused plot plan with an existing house, proposed addition, setbacks, driveway, and lot layout. The right side shows a survey-style plan with precise boundary information, bearings, dimensions, structures, and legal survey details.

What Is a Plot Plan?

A plot plan is a top-down drawing of a property that shows existing structures, proposed work, property lines, setbacks, access, and other site details. In many Canadian permit situations, people also use the term site plan for this type of drawing.

A plot plan may show:

• property boundaries;
• lot dimensions;
• existing house and structures;
• proposed addition, deck, shed, garage, pool, porch, or other work;
• front, side, and rear yard setbacks;
• driveway and vehicle access;
• walkways, stairs, patios, and entrances;
• easements or rights-of-way where known;
• utilities or services where relevant;
• landscaping, open space, grading, or drainage notes where required;
• north arrow, scale, labels, dimensions, and notes.

For building permits, the main job of a plot plan is to help the municipality understand where the proposed work will be located and whether it appears to meet zoning and site-layout requirements.

What Is a Survey Plan?

A survey plan is a more formal property drawing prepared by a licensed land surveyor. It is used when accurate boundary location, legal survey information, structures relative to boundaries, easements, encroachments, or title-related issues matter.

A survey plan may show:

• legal property boundaries;
• bearings and precise boundary dimensions;
• survey monuments or markers;
• building locations relative to boundaries;
• fences, garages, sheds, decks, or other improvements;
• registered easements or encumbrances;
• rights-of-way;
• encroachments where identified;
• legal plan numbers or survey references;
• surveyor certification or professional seal where applicable.

The Association of Ontario Land Surveyors explains that a Surveyor’s Real Property Report is prepared to show the location of buildings or structures relative to the boundaries of a unit of land, and can also show physical features and registered encumbrances such as easements. [1]

Plot Plan vs Survey Plan: Main Difference

The main difference is the purpose.

A plot plan is usually created to support a project. It answers the question: Where will the proposed work go?

A survey plan is usually created to establish or document accurate property information. It answers the question: Where are the legal boundaries and existing improvements?

Question	Plot Plan	Survey Plan
Main purpose	Permit and planning review	Legal boundary and property accuracy
Usually prepared by	Drafting service, designer, homeowner, builder, or consultant	Licensed land surveyor
Shows proposed work?	Usually yes	Not always
Shows legal boundary accuracy?	May rely on available property information	Yes, when prepared as a legal survey document
Common use	Building permits, additions, decks, sheds, garages, pools	Property sale, financing, boundary verification, legal disputes, compliance
Can replace the other?	No, not when a legal survey is required	Not always, because it may not show proposed work clearly

When You Usually Need a Plot Plan

You usually need a plot plan when you are trying to show a municipality where new work will be located on your property. This is common for residential building permit applications.

A plot plan may be useful for:

• home additions;
• new houses;
• detached garages;
• sheds and accessory buildings;
• decks and porches;
• pools and hot tubs;
• carports;
• basement entrances;
• secondary suites or garden suites;
• laneway houses;
• driveway widening;
• retaining walls;
• patio covers or covered outdoor areas.

City of Edmonton says a site plan for house permits should include items such as municipal address, legal description, north arrow, scale, property lines, property dimensions, streets and lanes, easements, rights-of-way, restrictive covenants, site depth, site width, setbacks, and distances between buildings. [2]

City of Toronto’s homeowner building permit guide says a site plan should show property lines, lot area, rights-of-way or easements, existing and proposed buildings, dimensions, setback dimensions, and zoning information such as lot coverage. [3]

When You Usually Need a Survey Plan

You usually need a survey plan when the exact legal location of property boundaries, buildings, easements, or encroachments matters.

A survey plan may be needed for:

• buying or selling a property;
• refinancing or mortgage requirements;
• boundary disputes;
• fence disputes;
• encroachment questions;
• subdivision or land severance;
• legal property descriptions;
• municipal compliance review;
• projects very close to a property line;
• projects affected by easements or rights-of-way;
• situations where the municipality specifically requests a current survey.

City of Calgary explains that a Certificate of Compliance confirms that the locations of structures on a property comply with the Land Use Bylaw, and that this is confirmed on a Real Property Report prepared by an Alberta land surveyor. [4]

That is the important difference. A plot plan can help show a proposed project for permit review, but a survey plan or Real Property Report can provide legal survey information that a basic plot plan does not provide.

Can a Plot Plan Be Made From a Survey?

Yes. In many cases, a survey plan is one of the best starting documents for preparing a plot plan.

A survey may provide:

• accurate property boundaries;
• existing house location;
• existing garage, shed, deck, fence, or driveway location;
• easement information;
• lot dimensions;
• legal plan references;
• existing improvements relative to boundaries.

A plot plan can then add the proposed work, such as a deck, addition, garage, shed, pool, porch, driveway change, or carport.

This is often the strongest setup for a permit package: use the survey information as the base, then add the proposed work clearly for permit review.

Can a Survey Plan Replace a Plot Plan?

Sometimes, but not always.

A survey plan may show the existing property very accurately, but it may not show the proposed work. If you are applying for a building permit, the municipality usually needs to see where the new project will be located, how large it will be, and how far it will be from property lines and existing structures.

For example, an old survey may show the existing house and garage, but it may not show your proposed rear addition. In that case, the survey can be used as a base, but a permit-focused plot plan may still be needed.

Can a Plot Plan Replace a Survey Plan?

Usually no, not when legal boundary accuracy is required.

A plot plan can show property lines and dimensions based on available information, but it is not the same as a legal survey. If the municipality, lender, lawyer, buyer, neighbour, or title-related process needs official boundary confirmation, a plot plan is not a substitute for a survey plan prepared by a licensed land surveyor.

This matters most when:

• the proposed work is close to a lot line;
• the boundary location is uncertain;
• there is a dispute with a neighbour;
• a fence, garage, shed, or deck may encroach;
• a legal easement affects the work area;
• a compliance certificate or legal survey document is required;
• the municipality specifically asks for a current survey.

What a Plot Plan Usually Shows

A permit-ready plot plan should be clear and easy to review. The goal is not to create a legal survey. The goal is to help the municipality understand the property layout and proposed work.

A plot plan may include:

• property address;
• property lines and lot dimensions;
• existing house;
• existing garage, shed, deck, porch, pool, driveway, or other structures;
• proposed work clearly labelled;
• dimensions of proposed work;
• setbacks from proposed work to property lines;
• distance to existing structures;
• driveway and access;
• walkways and entrances;
• easements or rights-of-way where known;
• grading or drainage notes where required;
• north arrow, scale, legend, and notes.

For a proposed addition, City of Edmonton says the site plan must include a north arrow, property address, streets and avenues, property-line dimensions, proposed and existing buildings and structures with location, measurements, and setbacks, plus applicable caveats, covenants, and easements. [5]

What a Survey Plan Usually Shows

A survey plan focuses on measured property information and legal accuracy. Exact contents vary by province, survey type, and purpose, but a survey plan may include:

• legal property boundaries;
• bearings and distances;
• survey monuments;
• building outlines;
• fences, decks, garages, sheds, and other improvements;
• easements or registered encumbrances;
• encroachments where identified;
• adjacent streets or lanes;
• surveyor notes;
• professional certification.

The Association of Ontario Land Surveyors says a Surveyor’s Real Property Report is prepared to illustrate the location of buildings or structures relative to boundaries, and to
