The Permit Journey

Seven Steps in the Residential Building Permit Process

The exact requirements vary by project and municipality, but most residential permit applications follow this general path.

1

Initial Project Review

We learn what you are planning, review the available documents and identify the general permit scope.

2

Property & Zoning Review

Relevant setbacks, lot coverage, building height, use, parking and property constraints are reviewed.

3

Existing-Condition Documentation

Measurements, photographs, survey information and relevant existing construction are documented.

4

Design & Permit Drawings

Scaled, dimensioned and coordinated drawings are prepared for the proposed residential work.

5

Engineering & Specialist Coordination

Structural, mechanical, plumbing, energy, grading or other supporting information is coordinated where required.

6

Application & Municipal Submission

Required forms, drawings and supporting documents are organized for municipal submission. Applicable municipal fees are paid as required by the reviewing authority.

7

Review Comments & Permit Decision

The municipality reviews the proposed work for Building Code compliance and applicable law, which can include local zoning requirements, before a permit decision.

Municipal Plan Examination

What Happens During Municipal Review?

The municipality examines the application according to the project type and applicable review requirements.

01

Zoning Review

Land use, building placement, setbacks, height, parking and other zoning requirements are examined.

02

Building Code Review

Plans are examined for applicable Ontario Building Code requirements.

03

Specialist Review

Mechanical, plumbing, drainage or other specialist reviews may apply depending on the project.

04

Decision

The municipality may approve the application, request revisions or identify outstanding requirements.

Review Comments

What Happens if the Municipality Requests Revisions?

Review comments are a normal part of many permit applications. They may request clarification, additional information or changes to the submitted drawings.

  • Comments related to our scope are reviewed
  • Required clarifications or revisions are coordinated
  • Updated drawings are prepared for resubmission
  • Major scope changes may require additional services
After Permit Issuance

Approved Documents Must Guide Construction

Construction must follow the issued permit and approved drawings. Required inspections must be requested at the appropriate stages.

  • Keep approved permit documents available on site
  • Build according to the approved drawings
  • Book required municipal inspections
  • Coordinate changes before covering the work
  • Submit revisions when permit changes are required
Avoidable Permit Delays

What Can Slow Down a Permit Application?

Incomplete Drawings

Missing dimensions, details or uncoordinated plans can create review questions.

Missing Forms

Outdated, unsigned or incomplete application forms can hold up intake.

Zoning Issues

Setback, height, parking or use issues may require additional review or approvals.

Outstanding Applicable Law

Heritage, conservation, planning or other approvals may need to be resolved.

Uncoordinated Engineering

Structural and architectural information must agree across the permit package.

Design Changes During Review

Major changes can require new drawings, specialist updates and additional review.
