Why a kitchen addition is priced as a full project

Three things that make it different from a straight room addition.

Plumbing has to extend, not just relocate

New floor space for a kitchen usually means extending supply and drain lines further than a same-footprint renovation would, which is its own scope of work.

Electrical load adds up fast

A kitchen's appliance circuits, task lighting and often an island add meaningfully to the electrical scope compared with a bedroom or office addition of the same size.

It still has to fit the setback

Extending the kitchen footprint is subject to the same rear-yard setback rule as any other addition, so we confirm your lot has room before designing the layout.

Why the price is a full-project figure, not a rate per square foot

A kitchen addition is priced as a full-project total, because the cost is driven as much by plumbing, electrical and cabinetry as by the structural shell itself. Two kitchen additions of the same square footage can differ by tens of thousands of dollars depending on appliance specification and finish level, which is why we quote this project as a whole rather than a bare per-square-foot rate.

What decides a kitchen addition's real cost

How far the plumbing has to travel

New floor space usually means extending supply and drain lines further than a same-footprint renovation. Ask how far the new layout moves the sink and dishwasher from the existing rough-in.

What the electrical scope includes

Appliance circuits, task lighting and an island add up. Ask for the electrical scope as its own line, not folded into a general 'rough-in' allowance.

What the cabinetry and finish allowance covers

This is usually the biggest swing factor between two kitchen addition quotes of the same size. Ask what's included in the number and what upgrades would add.

How the addition's footprint fits your setback

Extending the kitchen is subject to the same rear-yard setback rule as any other addition. Ask to see your lot's specific measurement.

Free Site visit and zoning check before any price
25% Rear yard setback as a share of lot depth, most urban neighbourhood zones (minimum 6 m)
1.5 m Common local footing depth used to clear frost
4 to 12 weeks Typical time to get a City of Ottawa permit

Kitchen Addition questions

Is a kitchen addition the same as a kitchen renovation?

No. An addition extends the house's footprint to add new floor space for the kitchen, which is a structural and permit project. A renovation within the existing walls doesn't add floor area and is a different scope entirely.

Why is a kitchen addition priced as a full project instead of per square foot?

Because plumbing, electrical and cabinetry drive so much of the cost that two additions of the same size can vary by tens of thousands of dollars depending on finish level. A single per-square-foot rate would hide that variation.

Can I add an island as part of the addition?

Yes, and it's worth telling us early, since an island typically needs its own electrical and sometimes plumbing rough-in, which we'll scope into the design from the start.

Does a kitchen addition need a building permit?

Yes, any addition that adds floor area needs a City of Ottawa building permit, and the plumbing and electrical work needs its own inspections as part of that process.
