Why Building Permit Group
Organized From the Start. Clear Through Every Step.
Residential permit projects can require several professional disciplines. We bring the property review, permit drawings, consultant coordination and municipal submission support into one organized workflow.
Project-First Planning
We Start With What You Want to Build.
The permit strategy is developed around the actual property, proposed work and municipality reviewing the application.
01
Property & Zoning Review
We review the property and applicable zoning early so design decisions are made with site-specific constraints in mind.
02
Project-Specific Drawings
Each drawing set is tailored to the actual house, proposed scope and municipality rather than built from a one-size-fits-all template.
03
Consultant Coordination
When required, we coordinate architects, qualified designers, professional engineers, structural engineers, HVAC designers, surveyors and other qualified consultants so the permit and technical information work together.
04
Municipal Review Support
We keep the permit package organized through municipal review and respond to drawing-related comments within the agreed scope.
Typical Permit Drawing Deliverables
Clear Drawings. Relevant Details. One Coordinated Package.
Depending on the project, the permit package may include some or all of the following.
Property lines, existing structures, proposed work and site conditions relevant to the application.
Dimensioned plans that distinguish existing construction from the proposed changes.
Exterior views showing building height, openings, roof form and the proposed appearance.
Sections and construction details used to communicate important assemblies and vertical relationships.
Project-specific construction and life-safety information included where applicable to the proposed work.
Coordination with architects, designers, engineers, HVAC designers, surveyors and other qualified consultants where required for the project.
Every project is different.
Municipalities may request different drawings, forms or supporting documents depending on the project type, property conditions and other applicable approvals.
When regulated professional services are required, each architect, engineer, designer, surveyor or other consultant remains responsible for the work they prepare, sign or seal.
Before Drawings Are Finalized
What Can Affect a Residential Permit?
A permit drawing set is only one part of the approval picture. Property-specific zoning, applicable law and technical requirements can influence the design, supporting documents and approvals needed before construction can begin.
Setbacks, Height & Lot Coverage
Municipal zoning by-laws can regulate where a building or addition may sit on a lot, its height, size, lot coverage, parking and other site-specific standards.
Easements & Site Constraints
Surveys, easements, existing structures and property conditions can affect placement and should be considered before the proposed design is finalized.
Construction & Life-Safety Requirements
The Ontario Building Code establishes technical requirements that may affect structure, spatial design, exits, fire safety, foundations and other aspects of residential work.
Structural Design When Required
Foundations, beams, load-bearing alterations, underpinning and other structural work may require design or review by a qualified professional engineer depending on the project.
Planning, Heritage & Conservation
Some properties or proposals can require approvals beyond the building permit process, including planning, heritage or conservation-related review where applicable.
Local Submission Requirements
Forms, drawings, supporting documents and review procedures are not identical across Ontario municipalities, so the property location matters when preparing a submission.
Requirements are property- and municipality-specific.
Ontario Building Code requirements, municipal zoning, planning approvals and other applicable
law should be reviewed using current official information for the property. Where requirements
differ or are unclear, they should be confirmed with the applicable authority rather than assumed.
Our Process
A Clear Path From Idea to Permit Review.
The exact steps can vary by project, but this is the typical sequence used to organize residential permit work.
Consultation
We review your goals, address, photos and any survey or drawings already available.
Property Review
Existing conditions and applicable zoning considerations are reviewed before design development.
Permit Drawings
Project-specific permit drawings are prepared for the proposed residential work, with qualified architectural or design professionals involved where required.
Consultant Coordination
Required information from architects, engineers, structural engineers, HVAC designers, surveyors and other qualified consultants is coordinated with the permit package.
Municipal Submission
Applicable drawings and supporting documentation are organized for submission.
Municipal Review
Drawing-related comments are addressed as required while the application moves through review.
Ontario Service Area
Residential Permit Services Across Ontario.
Ontario Building Code requirements provide a provincial technical framework, while zoning, planning procedures and submission requirements can differ by municipality. Each project should therefore be reviewed using the property address and the current requirements that apply there.

Ontario Residential Permits
Questions Homeowners Ask Before They Start.
Quick answers to the questions that usually come up before drawings, zoning review and a residential permit application.
How do I know if my project needs a building permit?
Permit requirements depend on the type of work and the municipality. New construction, home additions and many structural alterations generally require a permit. Start with the property address and proposed scope so the appropriate requirements can be reviewed.
What drawings are usually required for a residential building permit?
Depending on the project, a permit package may include a site plan, floor plans, exterior elevations, building sections and construction details. Structural or other supporting documents may also be required.
Why should zoning be reviewed before permit drawings are finalized?
Zoning can affect setbacks, lot coverage, building height, parking and other property-specific limits. Reviewing zoning early can help identify constraints before the design is finalized.
Will I need a structural engineer?
Some projects require structural engineering, especially where the work involves foundations, beams, load-bearing walls, underpinning or other structural changes. When required, Building Permit Group coordinates the project with a qualified professional engineer responsible for the engineering work they prepare and seal.
Can Building Permit Group help with the municipal submission?
Yes. Depending on the agreed scope, Building Permit Group can prepare and organize the permit drawings, coordinate required professional documentation, assist with municipal submission and address drawing-related review comments within the agreed scope.
How long does it take to get a building permit?
Review time varies by municipality, project type, application completeness and whether additional approvals or consultant information are required. Municipal review timelines are controlled by the reviewing municipality.
What should I send to start a project review?
Send the property address and a short description of what you want to build or change. Photos, a survey, existing plans or previous drawings are helpful when available.
What happens if my project does not comply with zoning?
The design may need to be revised, or a planning approval such as a minor variance may be required before the building permit can proceed.
Still not sure where your project fits?
Send us the property address and a short description of the work. We can help identify the right starting point.
