From Project Idea to Permit Package

Drawings That Clearly Explain the Proposed Work

Building permit drawings are the technical documents used by the municipality to understand what exists, what is changing and how the proposed construction is intended to comply with the applicable requirements.

The required package depends on the project. A small interior alteration may need floor plans and construction details, while an addition can require a site plan, all-level floor plans, roof plans, elevations, sections, structural information and energy-efficiency documentation.

Building Permit Group helps organize the drawing package around the actual property, the proposed work and the municipality reviewing the application.

Our Drawing and Permit Process

From Project Review to Municipal Submission

We organize the work into clear stages so you know what information is needed and what happens next.

1

Project Review

We review the property, proposed work and available plans, surveys or supporting documents.

2

Existing Conditions

Relevant dimensions, construction and site information are documented when required.

3

Design Coordination

The proposed layout and required specialist information are coordinated for the agreed scope.

4

Permit Package

We prepare the plans, sections, elevations, details and forms included in our services.

5

Application Support

Where included in the agreed scope, we assist with submission and address municipal comments that relate to the drawings we prepared.

Professional Coordination

When Other Professionals May Be Required

A complete application can require information from more than one discipline. The need depends on the project and applicable requirements.

Structural Engineering

Beams, foundations, retaining walls, underpinning and other structural work may require professional engineering.

Ontario Land Surveyor

Additions, garages and other exterior work may require a current survey or information based on a legal survey.

HVAC or Energy Design

Mechanical changes, new houses and some additions may require heating, ventilation or energy-efficiency documentation.

Arborist or Other Specialist Reports

Trees, conservation areas, grading, utilities or other applicable laws may require separate reports or approvals.

!

Permit Drawings Do Not Guarantee Permit Approval

The municipality issues the building permit after reviewing the complete application for compliance with the Building Code, zoning and other applicable laws. Approval timing depends on the project, application completeness, outside approvals and municipal review.

Frequently Asked Questions

Building Permit Drawing Questions

What information should I have before permit drawings begin?
Useful starting information can include an existing survey, previous drawings, property records, photographs and a clear description of the proposed work. What is actually needed is confirmed after the project and available documents are reviewed.
What if I do not have existing drawings of my house?
Existing drawings are helpful but are not always available. Depending on the project, relevant existing conditions can be documented from site measurements, available records and other reliable property information before the proposed drawings are prepared.
Can I submit my own sketches for a building permit?
Owner-prepared drawings may be accepted where the applicable requirements and any designer-qualification rules are satisfied. A simple sketch is not automatically a permit-ready drawing; the municipality may require scaled, dimensioned and sufficiently detailed documents for the proposed work.
Do permit drawings need a BCIN designer?
Ontario designer-qualification requirements depend on the building, the proposed work and any exemption that applies. Where qualification or registration information is required for the person taking responsibility for the design, it must be provided with the permit documents in the manner required by the Building Code.
When is a structural engineer required?
Engineering may be required for beams, posts, foundations, underpinning, retaining walls, large openings and other structural work. The need is confirmed after reviewing the existing conditions and proposed project.
Do you prepare drawings for existing construction without a permit?
Potentially. Existing work first needs to be documented and reviewed so the appropriate drawing, engineering, permit or inspection requirements can be identified. The municipality determines what is required and whether the existing work can be accepted or must be altered.
Can Building Permit Group submit my application?
Submission assistance can be included in the project scope. The exact service is confirmed with the homeowner and may include assembling the agreed permit documents and coordinating responses that relate to our work.
How long does it take to prepare permit drawings?
Drawing time depends on the project type, existing information, site conditions, design decisions and required specialist coordination. A project-specific schedule is provided after review.
How long does municipal permit review take?
Municipal review depends on the project classification, whether the application is complete, applicable-law approvals and any requested revisions. Ontario's Building Code establishes review periods for complete applications, but the period that applies depends on the type of project.
How much do residential building permit drawings cost?
Pricing depends on project size, complexity, existing conditions, required drawings and specialist coordination. Building Permit Group provides a project-specific quotation after reviewing the scope.
