What Is the Committee of Adjustment? (Toronto Homeowners Guide) – 416 Construction

If you’re planning a home addition, building a custom home, adding a second story, or converting a property into a duplex, triplex, or fourplex in Toronto or the GTA, you may need approval from the Committee of Adjustment before you can get a building permit.

Many homeowners don’t realize this step exists until their building permit application gets denied because the design does not meet zoning by-laws. That’s where the Committee of Adjustment process comes in.

This is one of the most important steps in the building and development process in Toronto and if done correctly, it can significantly increase your property value and development potential.

What Is the Committee of Adjustment?

The Committee of Adjustment is a municipal body that reviews and approves requests from property owners who want to build something that does not fully comply with the current zoning by-laws.

In simple terms, if your project doesn’t meet zoning rules, you must ask the city for permission. This permission is called a minor variance or consent.

Common reasons you may need Committee of Adjustment approval include:

• Building a home addition that is too large

• Building closer to the property line than allowed

• Adding a second story

• Building a laneway suite or garden suite

• Converting a single-family home into a duplex, triplex, or fourplex

• Severing a lot into two properties

• Building a new custom home that exceeds zoning limits

• Legalizing basement apartments

• Adding a rear extension

• Adding a third unit to a property

If your project does not meet zoning, you cannot get a building permit until Committee of Adjustment approval is granted.

Minor Variance vs Consent (Severance)

There are two main types of Committee of Adjustment applications:

Minor Variance

A minor variance is required when your project does not meet zoning requirements such as:

• Building height

• Lot coverage

• Floor Space Index (FSI)

• Setbacks

• Parking requirements

This is the most common type of application for:

• Home additions

• Second story additions

• Custom homes

• Rear extensions

• Basement walkouts

• Multiplex conversions

Consent (Severance)

A consent application (also called severance) is required when you want to:

• Divide a property into two lots

• Sell part of your land

• Create a new building lot

• Create easements or rights-of-way

This is common for:

• New custom home developments

• Lot severances

• Semi-detached developments

• Townhouse developments

The Committee of Adjustment Process (Step-by-Step)

Here is how the process typically works in Toronto:

1. Zoning Review & Feasibility Study

2. Architectural Drawings Prepared

3. Minor Variance / Consent Application Submitted

4. City Circulates Application to Departments

5. Public Notice Is Sent to Neighbours

6. Committee of Adjustment Hearing

7. Decision Issued (Approved / Refused / Deferred)

8. 20-Day Appeal Period

9. Building Permit Application Submitted

10. Construction Begins

How Long Does the Committee of Adjustment Process Take in Toronto?

The Committee of Adjustment process in Toronto typically takes 2 to 4 months, depending on the complexity of the project, the number of variances required, and whether the application is approved on the first submission.

However, in some cases, the process can take 6 months to 1 year to fully complete.

Delays can happen if:

• The city requests revised drawings

• There are multiple variances

• Neighbours object to the application

• The application is deferred to a later hearing

• The application is refused and must be redesigned and resubmitted

• The decision is appealed to the Ontario Land Tribunal (OLT)

• Additional studies are required (planning reports, arborist reports, grading, parking studies, etc.)

Because of this, it is very important to work with an experienced designer, planner, or design-build company that understands zoning by-laws and the Committee of Adjustment process before submitting drawings.

At 416 Construction, we review zoning, prepare architectural drawings, submit Committee of Adjustment applications, and handle the building permit and construction process, making the entire process much smoother for homeowners and investors.

Pro Tip (Very Important)

One of the biggest mistakes homeowners make is designing first and checking zoning later. This often leads to delays, redesign costs, and resubmissions.

The correct order should be:

1. Zoning Review

2. Feasibility Study

3. Architectural Drawings

4. Committee of Adjustment Application (if required)

5. Building Permit Application

6. Construction

This approach saves time, money, and reduces the risk of refusal.

Committee of Adjustment FAQs (Toronto)

Do I need Committee of Adjustment approval before a building permit in Toronto?

Yes. If your project does not comply with zoning by-laws (setbacks, height, lot coverage, FSI, parking, etc.), you must receive Committee of Adjustment approval before you can apply for a building permit.

How much does a Committee of Adjustment application cost in Toronto?

Costs vary depending on the project, but typically include city application fees, architectural drawings, planning reports (if required), and engineering drawings.

Can my neighbours stop my Committee of Adjustment application?

Neighbours can object and speak at the hearing, but the committee makes the final decision based on planning rules, not opinions.

What happens if my Committee of Adjustment application is refused?

You can redesign and resubmit, or appeal the decision to the Ontario Land Tribunal (OLT).

Do I need architectural drawings for Committee of Adjustment?

Yes. The city requires detailed architectural drawings showing the proposed construction and zoning comparisons.

Can 416 Construction handle the entire Committee of Adjustment process?

Yes. 416 Construction provides zoning reviews, architectural drawings, Committee of Adjustment applications, building permits, and full construction services across Toronto and the GTA.

Why Committee of Adjustment Approval Can Increase Property Value

Getting approval allows you to build more square footage, add additional units, or build a larger home, which can significantly increase property value.

Examples:

• Adding a second story

• Adding a rear extension

• Converting a home into a triplex or fourplex

• Building a garden suite

• Severing a lot and building a second home

• Building a larger custom home than zoning allows

Many real estate investors and developers buy properties specifically for Committee of Adjustment approvals because of the value it creates.
