Commercial Washroom Permit Drawings in Toronto & the GTA
Commercial washroom work often needs more than a simple contractor sketch. When a project adds fixtures, relocates plumbing, changes partitions, upgrades accessibility, affects ventilation or supports a new commercial use, the city may need scaled permit drawings and code information before work starts.
Acadia Drafting prepares permit-ready commercial washroom drawings for tenants, landlords, contractors and business owners. We help show the proposed layout, plumbing fixture locations, barrier-free clearances, ventilation coordination and construction notes in a format municipal reviewers can understand.
☑New commercial washrooms, restroom banks and staff washrooms.
☑Barrier-free washroom upgrades and accessibility coordination.
☑Plumbing fixture layout, fixture counts and rough-in coordination.
☑Ventilation, exhaust, ceiling and trade coordination when required.
Commercial Washroom Projects We Can Help With:
- Adding a washroom to a retail, office, clinic, salon, gym, warehouse or restaurant unit.
- Relocating toilets, sinks, lavatories, floor drains or accessible washroom fixtures.
- Renovating a public washroom, staff washroom, universal washroom or multi-stall restroom.
- Upgrading an existing washroom for barrier-free access, turning space, grab bars or door clearances.
- Coordinating washrooms as part of a tenant fit-out, change-of-use or commercial interior renovation.

What Your Washroom Drawing Package Includes
A useful commercial washroom permit package should make the construction scope clear and show how the washroom works with the rest of the unit. The goal is to reduce city comments by showing dimensions, fixture locations, accessibility clearances and required coordination up front.
Depending on the project, Acadia can prepare or coordinate:
- Existing and proposed floor plans with washroom location, room names and dimensions.
- Toilet, sink, lavatory, urinal, floor drain and service sink locations where applicable.
- Barrier-free washroom layouts, door swings, turning space and fixture clearances.
- Partition, wall, door, ceiling and finish notes related to the washroom scope.
- Plumbing fixture schedule notes and consultant coordination when required.
- Ventilation or exhaust coordination for new or altered washroom layouts.
- OBC notes for accessibility, life safety and use/occupancy coordination.
- City comment revisions after permit review.
When Does a Commercial Washroom Need a Permit?
A permit is commonly required when the work changes plumbing, walls, fire/life-safety conditions, accessibility, ventilation or the approved use of the space. Cosmetic refreshes may be simpler, but the moment fixtures, drainage, partitions or barrier-free requirements are involved, the project should be reviewed before construction.
| Project Type | Why It Can Trigger Review | What to Show in the Drawings |
|---|---|---|
| Adding a new commercial washroom | New fixtures, partitions, doors, drainage, ventilation and accessibility may affect the permit scope. | Existing/proposed plans, fixture layout, plumbing coordination, wall/door notes and accessibility clearances. |
| Relocating toilets, sinks or drains | Moving plumbing can affect fixture counts, drainage runs, floor penetrations and inspection requirements. | Fixture locations, rough-in notes, floor drain locations, pipe coordination and affected floor/wall areas. |
| Barrier-free washroom upgrade | Public washrooms often need accessible paths, door widths, turning space, grab bars, signage and counter-height review. | Clear dimensions, turning radius, door swing, grab bar/fixture locations, lavatory clearance and signage notes. |
| Multi-stall washroom renovation | Partitions, fixture counts, exits, travel paths, finishes and ventilation can require coordinated review. | Stall layout, fixture schedule, reflected ceiling/exhaust notes and construction details. |
| Washroom work inside a tenant fit-out | The washroom is reviewed with the rest of the commercial unit layout, exits, occupancy and trade work. | Coordinated tenant layout, washroom plan, life-safety notes and consultant drawings if needed. |
| Washroom work tied to a change of use | A new business use can change washroom demand, accessibility expectations, occupant load or code review items. | Existing/proposed use plans, occupant load/code notes, fixture layout and zoning/use support where required. |
Washroom Permit Drawings vs. Related Commercial Permits
Commercial washrooms often overlap with broader permit scopes. Separating the scopes early helps the owner, tenant, contractor and landlord understand what needs to be submitted and which consultants may be needed.
| Scope | Best Fit | What Acadia Focuses On |
|---|---|---|
| Commercial washroom permit drawings | Adding, moving or upgrading washrooms inside an existing commercial unit. | Fixture layout, dimensions, accessibility, plumbing/HVAC coordination and permit-ready notes. |
| Tenant fit-out permit drawings | A leased unit is being built out for a new tenant, with washrooms as one part of the work. | Full unit layout, partitions, exits, washrooms, mechanical/plumbing coordination and construction notes. |
| Change-of-use permit drawings | The business use changes, such as retail to restaurant, office to clinic or warehouse to showroom. | Use review, occupant load, washroom/code requirements, accessibility and city comment support. |
| Mechanical/HVAC permit drawings | New or modified exhaust, make-up air, ductwork or mechanical systems are required. | Mechanical coordination and HVAC permit support where the washroom scope triggers it. |

Usually, yes. Adding a commercial washroom normally affects plumbing fixtures, drainage, partitions, doors, ventilation and accessibility, so the city may require permit drawings before construction starts.

A typical package may include existing and proposed floor plans, washroom layout drawings, fixture locations, dimensions, accessibility clearances, construction notes, reflected ceiling or exhaust coordination, and plumbing/mechanical consultant drawings where required.
Many public commercial washrooms must account for barrier-free access. The exact requirement depends on the building, use, renovation scope and existing conditions, but items like path of travel, door width, turning space, grab bars, signage and fixture clearances should be reviewed early.
Possibly. If the project adds fixtures, changes drainage, modifies exhaust, affects existing building systems or requires trade coordination, plumbing or mechanical information may be needed. Acadia can coordinate with consultants when the project scope requires it.
