Plumbing & electrical drawings
Plumbing, drainage and riser layouts, electrical and lighting plans, panel schedules and fire safety plans for homes, second units and commercial spaces.
Where most of our plumbing & electrical clients start
The sheets in a typical permit set
Every property is different, so we confirm the exact list with your city. Most applications include:
EXAMPLE SHEETS · ILLUSTRATIVE
Included when you work with KS
- Plumbing fixture layout
- Drain and vent routing
- Riser diagram
- Water supply and backflow notes
- Lighting and power layout
- Smoke and carbon monoxide alarm locations
We coordinate
- Your plumber and electrician
- Electrical Safety Authority notification through your electrician
- Grease interceptor sizing for food businesses
We tell you up front if any of these apply, so there are no surprise add-ons later.
Key requirements we design for
Drains & venting
Sizes and slopes for new fixtures.
Water supply
Sizing and backflow prevention where needed.
Fixture counts
Washrooms required for commercial occupancy.
Lighting & power
Locations for outlets, switches and fixtures.
Alarms
Smoke and carbon monoxide alarm locations.
Coordination
Fitting plumbing and power around structure.
Before we design: what we check
Plumbing is about gravity. We find the main stack and the building drain, then check whether a new fixture can reach them with the right slope. Where it cannot, we plan a pump or a different layout before you commit to a floor plan.
Venting is the next most common city comment. Every fixture needs a vent path, and in finished spaces that path has to fit inside walls you already have.
For power and lighting we plan outlet and switch locations around how the room will be used, and we place alarms where the code requires them so nothing has to move after inspection.
Why these applications get sent back
These are comments plan examiners often raise. We address each one in the drawings before we submit.
From site visit to issued permit
"Had a great experience working with them for our basement second dwelling unit project. The architectural work was done very professionally, with clear drawings, good communication, and attention to detail throughout the process."
