Commercial permit drawings are needed when a business is building, renovating, fitting out, changing use, adding washrooms, modifying HVAC/plumbing, or responding to city comments. A strong permit package should clearly show what exists, what is proposed, and how the work addresses zoning, Ontario Building Code, life safety, accessibility, washroom and trade requirements.
Acadia Drafting prepares permit-ready commercial drawings for business owners, landlords, contractors and tenants across Toronto and the GTA. We help organize the project scope before submission so municipal reviewers can understand the work without guessing.
☑ Existing and proposed commercial floor plans for permit submission.
☑ BCIN designer and engineer coordination when the project scope requires it.

☑ Support with city submission requirements, examiner comments and rejected permit drawings.
☑ Clear drawings for restaurants, retail stores, offices, clinics, warehouses and tenant fit-outs.

A commercial permit page should act like a hub, not a dead-end service page. If your project is a tenant fit-out, change of use, commercial washroom, HVAC change, restaurant, clinic, office, retail store or warehouse renovation, Acadia can help determine what drawings and coordination are likely needed before submission.
Our role is to turn the existing unit, proposed business use, landlord requirements and construction scope into a clear drawing package. When required, we coordinate with engineers or trade consultants so architectural, mechanical, structural, electrical and plumbing information supports the same permit application.

A strong commercial permit package usually answers five review questions: What is the existing use? What is the proposed use? What construction is changing? Are exits, washrooms, accessibility, fire/life safety, HVAC or plumbing affected? Which drawings or consultant documents are needed for the municipality?

Commercial permits can involve zoning, building code, life safety, accessibility, washrooms, HVAC, plumbing, landlord requirements and city examiner comments. These FAQs answer the questions business owners usually need before starting commercial permit drawings.
Many commercial interior renovations need a building permit when the work changes layout, partitions, exits, washrooms, plumbing, HVAC, fire/life safety, accessibility or the approved use of the space. Simple cosmetic finishes may be different, but the scope should be reviewed before construction starts.
A typical package may include existing and proposed floor plans, site/key plan information, life safety or code notes, construction details, washroom/plumbing/HVAC coordination, required forms and consultant drawings where the scope requires them.
Toronto permit fees depend on the scope. The 2026 schedule lists a minimum building permit fee of $214.79 and uses service-index calculations for many construction and alteration categories. Trade work, revisions, change of use, HVAC or plumbing items can add separate fees.
Zoning review checks whether the proposed business use and site conditions are permitted at the address. A building permit review checks whether the proposed construction or change complies with Building Code, life safety, accessibility and related requirements. Some commercial projects need both.
Yes. If the proposed business use differs from the previous approved use, the city may review occupancy, code compliance, life safety, accessibility, washrooms and ventilation. This is common when a retail, office or warehouse unit becomes a restaurant, clinic, studio or other use.
Send the unit address, proposed business use, lease or landlord requirements, existing drawings if available, photos, equipment layout, seating count if applicable, washroom/plumbing details and target opening date.
Restaurants often involve kitchen exhaust, plumbing, grease/interceptor coordination, washrooms, accessibility, ventilation, occupant load and fire/life safety review. More coordinated information usually means more review items before approval.
Yes. Send the examiner comment letter, application number and submitted drawings. We can review what the city requested, revise the drawings and coordinate missing information with the required consultants where needed.
