Compare qualified professionals for the mechanical plans, HVAC design, ventilation and engineering documentation your project may need. Keep the work coordinated as you move toward building permit approval.
Not every project needs an engineer. Start with the space you are building or changing, then compare the mechanical scope your project may require.
Kitchen ventilation, make-up air, HVAC and building permit documentation as required.
Post This Project →Heating, cooling, ventilation and revised mechanical layouts for tenant improvements.
Post This Project →Project-specific ventilation, equipment coordination and mechanical plans where needed.
Post This Project →Ventilation and heating/cooling design for changing occupancy and building use.
Post This Project →Mechanical design and coordination for additions, conversions and new residential buildings.
Post This Project →Assess heating, ventilation and mechanical changes alongside the building permit plans.
Post This Project →A quote for “HVAC drawings” may not cover ventilation calculations, equipment sizing, coordination or revisions. Compare the complete deliverables before you hire.
Illustrative scope only — not a promise of deliverables, price, time or permit approval.
The right quote explains what is included, what another discipline handles and what happens when municipal review requires revisions.
Example scopes only. Your project may require a different mix of plans, calculations or professional disciplines.
Start with what the permit application requires. Broader mechanical engineering and installation coordination can follow when relevant.
Design heating, cooling and ventilation systems within the engineer's agreed scope.
Address outdoor air, exhaust and make-up air where required for the building use.
Prepare heat-loss, heat-gain or system sizing calculations within the agreed scope.
Document equipment, ductwork layouts, ventilation and technical schedules for review.
Coordinate with plumbing designers or engineers where the project needs it.
Coordinate revisions and field review where included or professionally required.
Before paying for a drawing package, understand the actual sheets, calculations and coordination included in the professional's scope.
* Included only if required and agreed with the professional.
Illustrative document checklist, not a real engineering drawing, code review or permit-ready design.
Separate engineering design, building permit coordination and installation responsibilities before you commit.
Prepares mechanical engineering design, calculations and documentation within the authorized scope.
Prepares building plans and coordinates spatial, occupancy and envelope considerations.
Assesses structural changes or equipment-support requirements where applicable.
Handles plumbing system design and required plans where needed.
Coordinates relevant life-safety, smoke control or fire-protection interfaces where required.
Installs mechanical systems within the applicable trade and regulatory scope; engineering design is separate.
Professional qualifications, sealing and trade requirements vary by province or territory and project.
Your project may need an architect, mechanical engineer and other professionals. Compare quotes, manage files and review agreed deliverables without losing track of the permit submission.
Illustrative dashboard only, not a live project or client record.
If the municipality or another consultant requests additional documents, see the new work, responsible professional and cost before approving the change.
Illustrative workflow. Added work is subject to a separately agreed scope and milestone.
Keep the building permit objective visible at every stage.
Tell professionals what you are building, changing and where the property is located.
Compare experience, drawings, calculations, timing and the proposed fee.
Agree on required plans, code-related calculations, revisions and other professional roles.
Track files, milestones, submitted plans and change requests in the project dashboard.
Use the completed professional documentation for the applicable municipal building permit process.
Use Permit Wallet to fund the agreed work through Interac e-Transfer. Review submitted deliverables and approve a milestone before its payout is initiated. Either party can raise a dispute.
*After client approval, payout is initiated and clears in seven days before bank transfer.
Illustrative files and milestone only.
Common questions from clients planning a building permit project.
A mechanical engineer may design and document heating, ventilation, air-conditioning, exhaust and related mechanical systems. Whether engineering documentation is required depends on the project, applicable building code and jurisdiction.
Some renovations and commercial fit-outs require mechanical design or professional engineering, especially where building use, ventilation, exhaust or HVAC loads change. Confirm the requirements for the specific building and location.
No. The drawing and calculation requirements depend on the project and municipality. Some building permit applications include mechanical plans, and certain standalone mechanical projects can also have their own permit process.
Compare the systems covered, plans and calculations included, equipment schedules, coordination with other disciplines, revision rounds, field reviews if applicable, timing, milestones and total fee.
Not automatically. Confirm whether ventilation calculations, heat-loss and heat-gain calculations, equipment sizing and related reports are included in the professional's proposed scope.
That depends on the engineer's authorized practice, experience, the project and local professional requirements. A building permit submission may involve a designer or architect and multiple engineering disciplines.
Where professional authentication is required, confirm the engineer is authorized to practise in the project's province or territory and that the agreed deliverables include the required authentication.
A suitably qualified mechanical engineer may design the applicable ventilation and exhaust systems. Commercial kitchen projects may also require specialized fire-protection, plumbing and other coordinated professional scopes.
Engineering design and mechanical installation are different services. Confirm whether you need an engineer, a mechanical contractor or both, and identify who is responsible for each stage.
Yes. You can post a project focused on the necessary design drawings and documentation first. Construction can be coordinated separately when your design and permitting needs are clear.
No. Independent professionals prepare or coordinate the agreed documentation, and the responsible municipality or authority reviews the application and decides whether to issue the building permit.
No. Permit.ca is a network connecting clients with independent mechanical engineers, designers, architects, contractors and other building professionals. It is not an engineering or architectural firm and does not directly provide mechanical engineering, HVAC installation or other regulated professional services.
Post your project, compare mechanical engineers by plans, calculations, experience, timing and scope, then coordinate the work as you move toward building permit approval.
