What is changing?
New walls, equipment, fixtures, occupancy, use or building systems can affect the drawing scope.
Drawings • coordination • review support
Not sure which drawings your project requires? 4MS can review the scope, coordinate the necessary design disciplines and prepare clear, permit-ready documentation for municipal review.

01 / Start with the scope
That is a normal starting point. The required documentation depends on the building, proposed use, existing conditions and municipal review path. 4MS begins by clarifying what is changing and which architectural or engineering inputs may be required.
Tell us what you are planning ↗New walls, equipment, fixtures, occupancy, use or building systems can affect the drawing scope.
Existing plans, landlord drawings, surveys and equipment information help establish a reliable starting point.
Architectural, mechanical, electrical, plumbing or structural information may be needed depending on the work.
The applicable municipality determines submission requirements and ultimately decides whether a permit is issued.
02 / Permit package capabilities
Each package is tailored to the scope and coordinated so reviewers and contractors can understand the design intent.
Project definition
Review the proposed work, available information and likely design disciplines before documentation begins.
Building layout
Floor plans, layouts, elevations and related information through qualified project professionals where applicable.
Building systems
Equipment, ventilation, ductwork, water, drainage and fixture requirements coordinated with the space.
Wider disciplines
Coordinate additional engineering information when it forms part of the agreed project scope.
Submission documents
Clear documentation organized to support municipal review without guaranteeing permit approval.
After submission
Coordinate applicable responses and revisions when the reviewing authority requests clarification.
03 / Project path
A defined sequence helps owners, contractors and consultants understand what happens next and where decisions are required.
Gather available plans, photos, equipment details and known building information.
Clarify the proposed work, intended use and likely disciplines.
Develop architectural and engineering solutions for the agreed scope.
Align layouts, systems, equipment and discipline interfaces.
Prepare and assemble clear documentation for municipal review.
Support the submission workflow as agreed and respond to applicable questions.
Coordinate reasonable drawing updates arising from review comments.
Develop or clarify information needed for pricing and construction where included.
04 / Common project types
Renovations and changes of use often affect several building systems at once. Coordinating them early creates a clearer submission package.
Layouts, kitchen equipment, HVAC, exhaust, make-up air, plumbing and related coordination where applicable.
Floor-plan, ventilation, comfort, washroom and building-system documentation for new or converted spaces.
pharmacy and medical spaces with coordinated layouts, fixtures, ventilation and tenant-improvement requirements.
Leasehold improvements, renovations and fit-outs within existing commercial buildings.
Coordinate documentation when a space’s proposed operation differs from its previous use.
Permit and engineering documentation where appropriate to the project and agreed scope.
4MS prepares coordinated documentation and can support applicable municipal review comments. The authority having jurisdiction determines submission requirements, review timelines and whether a permit is issued.
05 / Review support
Review comments may request clarification, additional information or revisions. When those comments relate to the agreed scope, 4MS can coordinate responses across the relevant disciplines and update documentation as appropriate.
06 / Common questions
Permit requirements vary by project and municipality. A scope review is the most reliable place to begin.
Existing drawings, photos, site information, the intended building use, proposed changes, equipment details and known landlord or municipal requirements are useful starting points.
4MS can review the proposed work and available information to help identify likely architectural and engineering scope. Final submission requirements are determined by the applicable authority.
Yes. Tenant improvements, renovations and change-of-use projects commonly begin with an existing space and partial building information.
Yes. Mechanical, HVAC, plumbing and other applicable disciplines can be coordinated within a broader permit package.
Comments relating to the agreed scope can be reviewed, coordinated and addressed through updated documentation where appropriate.
No. 4MS prepares permit-ready documentation and provides review support, but approval decisions and timelines remain with the municipality or other applicable authority.
