What drives whole-house renovation cost
- Scope — cosmetic refresh vs. full gut-to-the-studs with new mechanical, electrical, and plumbing
- Home size — total square footage sets the baseline for every trade and material
- Kitchens and bathrooms — the most expensive rooms, and a whole-house reno usually touches all of them
- Structural or layout changes, updating systems to code, and any hidden issues found once walls open
Whole-House Renovation cost in Illinois — frequently asked questions
How much does it cost to gut and renovate a whole house?
A full gut renovation — new electrical, plumbing, HVAC, insulation, drywall, kitchen, baths, and finishes — sits at the high end of this range and can exceed it on larger or higher-end homes. Set size to Large and quality to High-end to model a deep gut.
Is it cheaper to renovate or tear down and rebuild?
Renovating is usually cheaper if the foundation and structure are sound. A tear-down and rebuild can make more sense when the home has major structural, foundation, or code problems, or when you want a fundamentally different layout. Compare a full-gut estimate against local new-build costs.
Should I renovate room by room or all at once?
Doing it all at once is usually more cost-efficient — shared permits, one mobilization of crews, and no repeated demolition — but requires more cash up front and often moving out. Phasing spreads the cost but you pay setup and cleanup multiple times.
