Mechanical System Layouts
Floor-by-floor HVAC layouts showing the proposed mechanical system and distribution.
Post your project once. Compare professionals for HVAC layouts, equipment schedules, heat-loss/heat-gain calculations, duct design, ventilation and mechanical permit support — all in one place.
A strong mechanical submission starts with drawings that clearly show equipment, ventilation, duct layouts and the calculations the reviewing authority needs.
Mechanical plans • duct layouts • equipment schedules • ventilation • calculations • details
Permit.ca is a network connecting clients with independent professionals. Each professional is responsible for their own work. Permit.ca does not guarantee municipal approvals.
A mechanical permit package may need more than a floor plan with duct lines. Equipment information, calculations, ventilation design and coordination with the building plans can all affect the submission.
A residential HVAC layout, commercial mechanical design and complex engineered system are not the same scope. Compare deliverables, calculations, qualifications and permit support before you hire.
Professional requirements vary by building type, jurisdiction and complexity. Confirm whether the quote includes design, calculations, equipment schedules, revisions and permit-response support.
Mechanical layouts, equipment schedules, ductwork and ventilation documents within the designer’s permitted scope.

Floor-by-floor HVAC layouts showing the proposed mechanical system and distribution.
Equipment type, location, size and schedules where required.
Heat-loss/heat-gain calculations, duct design calculations and mechanical ventilation calculations or design where applicable.
Updated drawings, calculations or supporting documents when the municipality requests clarification or changes.
Share the property, building type, project scope, available architectural plans, equipment information and permit stage.
Review proposed drawings, calculations, timeline, qualifications, revisions and permit-support scope.
Agree on the professional scope and fund the current milestone through the platform before that stage begins.
Keep files, calculations, messages, milestone submissions, municipal comments and revisions attached to one project.
Keep payments tied to the agreed stage — such as mechanical layouts, calculations, permit submission support or revisions.
Client funds the agreed milestone through the Permit Wallet.
The professional submits the agreed milestone deliverables.
Client reviews the submission and approves or raises an issue.
The professional receives the approved payout seven days after client approval.
Manage professional quotes, mechanical plans, equipment information, calculations, milestone submissions, municipal comments and revisions from one organized project record.
They are project drawings and supporting documents that show the proposed mechanical system, equipment, ductwork, ventilation and related design information needed for permit review. The exact requirements depend on the project and municipality.
Depending on the project, it can include mechanical system layouts by floor, equipment type/location/size, equipment schedules, heat-loss and heat-gain calculations, duct design calculations, and mechanical ventilation calculations or design.
Not always. Some projects use a stand-alone mechanical permit while others include HVAC as a related permit tied to the main building permit. The municipality determines the application path.
The required professional depends on the project, building type, jurisdiction and scope. A qualified designer, engineer or other authorized professional may be required. The professional preparing the work is responsible for their own regulated scope.
Not necessarily. HVAC drawings can be one part of a broader permit package. Architectural, structural, plumbing, electrical, fire-protection or other documents may also be required depending on the project.
Include the property address, building type, project scope, existing drawings, architectural plans if available, proposed HVAC work, equipment information, photos and any municipal comments or permit reference numbers.
No. Permit.ca is a network. Independent professionals provide the HVAC or mechanical design services. Permit.ca does not prepare or certify drawings, review technical design, issue permits or guarantee approval.
No. Clients can post a project and compare quotes without a client platform fee.
