Interior remodeling means changing the inside of a house without extending it: reworking layouts, replacing finishes, upgrading systems and reconfiguring how rooms relate to each other. It sits between decorating and building an addition.
The scope varies enormously, so the useful way to approach it is room by room, because each room has a different cost per square foot and a different set of constraints.
What each room costs and why they differ so much
Kitchens and bathrooms are the expensive rooms because they are trade-dense. Every square foot contains plumbing, electrical, ventilation, waterproofing and cabinetry. Kitchens run $300 to $650 per square foot, bathrooms $350 to $700.
Living spaces, bedrooms and dining rooms are the cheapest because they are mostly finish work: flooring, walls, trim, lighting. Sixty to one hundred and forty dollars per square foot for a comprehensive refresh, less if the walls stay where they are.
Basements and attics sit in between, and their cost is dominated by the envelope rather than the finish: moisture control, insulation, conditioning and egress. One hundred and ten to two hundred and thirty dollars per square foot.
The structural work that connects them, removing walls to open a plan, sits on top of all of it, typically four to twelve thousand dollars per bearing wall with engineering.
The order to take rooms in
- Systems throughout. Electrical, plumbing and HVAC work that affects multiple rooms goes first, while walls are open.
- Structural changes. Wall removals and openings, before any finishes anywhere.
- Kitchen. The longest single project and the one that most disrupts daily life. Getting it done releases the rest.
- Bathrooms. One at a time in a house with more than one, so there is always a working bathroom.
- Living spaces and bedrooms. Finish work, quicker and much less disruptive.
- Flooring. Late, running continuously through the finished spaces.
- Trim, paint and lighting. Last.
Mistakes we see most often
- Finishing bedrooms first because they are cheap and easy, then damaging them moving materials through for the kitchen.
- Doing bathrooms simultaneously in a two-bathroom house.
- Laying flooring before the messy work is done.
- Sequencing room by room in isolation, so the electrician visits six times instead of once.
What this means in the Capital Region
In older Capital Region homes the most common interior remodeling project is opening up a compartmentalised ground floor. These houses were built with separate rooms for separate functions, and modern households generally want the kitchen connected to where people actually are.
That is nearly always a structural question, and in a balloon-framed house the wall you want to remove may be carrying load from two storeys. It is routine work with a properly sized beam and a load path to the foundation, and it is the single item most worth establishing the cost of before planning anything else.

Frequently asked questions
How much does interior remodeling cost?
Sixty to three hundred dollars per square foot depending entirely on the room. Kitchens and bathrooms are at the top because they are trade-dense; bedrooms and living rooms are at the bottom because they are mostly finish work.
Should I do the whole house at once?
If you can move out and fund it, yes. It is more efficient on mobilisation, permits and trade visits, and it avoids finished rooms being damaged by later work. If you are living in it, phasing is more comfortable and costs somewhat more.
What order should I remodel rooms in?
Systems and structure first, then kitchen, then bathrooms one at a time, then living spaces, then flooring, then trim and paint.
Do I need a permit for interior remodeling?
For anything structural, electrical or plumbing, yes. For pure finish work, generally not. Most whole-house interior projects include permitted work somewhere in them.
