A whole-home renovation touches every trade in your house at once, which is exactly why so many of them go sideways. The plumber finishes before the framer knows where the new wall goes. The electrician gets locked out of a room because drywall went up early. The homeowner signs a contract without a written payment schedule and then spends six months arguing about change orders. None of this is inevitable. It’s a planning problem, and planning problems have concrete solutions.
Define the Scope Before You Call Anyone
Before you contact a single contractor, write down what you actually want changed, room by room. Separate “must change” from “would like to change.” A kitchen that needs new electrical for code reasons is a must. A kitchen island made of reclaimed barn wood is a preference. This list becomes the backbone of every bid you request, and it keeps three different contractors from quoting three different projects.
Measure your square footage honestly. Whole-home renovations in most U.S. markets run somewhere between $150 and $400 per square foot depending on how much structural and mechanical work is involved, with kitchens and bathrooms pulling the average up because of plumbing, tile, and cabinetry costs. A 2,200 square foot house gutted to the studs and rebuilt with mid-range finishes often lands between $330,000 and $550,000. Cosmetic-only work (paint, flooring, fixtures, no wall moves) can come in at a third of that.
Choosing a General Contractor Who Won’t Disappear Mid-Project
The contractor you pick controls your schedule, your budget, and your stress level for the next several months. Spend real time on this decision instead of defaulting to the first bid that comes in low.
- Ask for three references from projects completed in the last 18 months, and actually call them. Ask what went wrong and how it was handled, not just whether they liked the final result.
- Confirm the license and insurance directly with your state licensing board and the insurance carrier, not just by looking at a certificate the contractor hands you.
- Get at least three bids built from the same written scope document. If the bids vary by more than 20-25%, ask each contractor to walk you through their line items before deciding.
- Read the payment schedule in the contract. A standard structure ties payments to completed milestones, not calendar dates. Be wary of any contractor asking for more than 10-15% as a deposit before work starts.
- Check how many active projects the contractor is running simultaneously. A GC juggling six large jobs with one project manager is likely to leave your house understaffed for days at a time.
For homeowners in the Kansas City metro, a locally established outfit like kcitygeneralcontractors.com is worth including in your bid list specifically because local contractors already have working relationships with the permit offices in Jackson, Johnson, and Wyandotte counties, which cuts down on the back-and-forth that out-of-area contractors often run into.
Sequencing the Work So You Don’t Pay to Redo It
Construction sequence is not a matter of taste, it follows the physical reality of what has to happen before what. Getting it wrong means paying a crew to rip out finished work to access something underneath it.
A typical whole-home gut renovation sequence looks like this:
- Demolition and structural work (removing or adding walls, repairing foundation issues, framing new layouts)
- Rough mechanicals: plumbing supply and drain lines, electrical wiring, HVAC ductwork, all installed before walls close up
- Inspections of rough mechanical work, required by code before anything gets covered
- Insulation and drywall
- Interior trim, doors, and paint
- Flooring, usually installed after paint to avoid drips and dust but before cabinetry in kitchens
- Cabinetry, countertops, and tile
- Fixture installation: plumbing fixtures, light fixtures, outlet covers, hardware
- Final punch list and final inspection
Flooring order is one of the most common mistakes homeowners make when they try to manage subcontractors directly. Hardwood should go down before cabinets in most cases, so the floor runs continuously under where cabinets will sit, which matters if you ever remove or reconfigure cabinetry later. Tile floors, on the other hand, are sometimes installed after cabinets to save material cost, since nobody will ever see the tile under a cabinet base. A contractor who has done dozens of these projects will have this sequencing memorized. A homeowner acting as their own GC usually learns it by paying for a redo.
Budgeting: The Numbers Nobody Puts in the Brochure
Set your renovation budget at the amount you’re willing to spend, then build in a contingency fund of 15-20% on top of that for a whole-home project, or 10% for cosmetic-only work. Older homes, anything built before 1990, tend to land at the higher end of that range because of what inspectors find once walls open up: outdated wiring, undersized electrical panels, galvanized pipe that’s corroding from the inside, or asbestos tile that needs professional abatement.
Common budget-busting discoveries include:
- Electrical panels rated at 100 amps that need upgrading to 200 amps to support modern HVAC, induction ranges, and EV charging, typically $2,500-$4,500
- Galvanized or polybutylene plumbing that needs full replacement instead of a patch job, often $8,000-$15,000 for a mid-size house
- Structural rot in sill plates or floor joists found once flooring comes up, which can add $3,000-$10,000 depending on extent
- Asbestos-containing materials in vinyl tile, pipe insulation, or popcorn ceilings in homes built before 1980, requiring licensed abatement before demolition continues
Build your budget in writing with your contractor before signing, broken down by category: demolition, structural, mechanical, finishes, fixtures, and permits. Keep the contingency fund in a separate line, not folded into the main budget, so you can see clearly when you’re dipping into it and why.
Permits: What You Need and How Long It Actually Takes
Permit requirements vary by city and county, but a whole-home renovation involving structural changes, new electrical circuits, or plumbing relocation will almost always require separate permits for building, electrical, plumbing, and mechanical work. Cosmetic work like paint, flooring, and cabinet swaps usually doesn’t require a permit at all.
Expect permit review timelines of 2-6 weeks for standard residential projects, longer if your plans include structural changes that require an engineer’s stamp. Permit fees are typically calculated as a percentage of the project valuation, often in the 1-2% range, so a $400,000 renovation might carry $4,000-$8,000 in permit costs across all trades. Skipping permits to save time or money creates real risk: unpermitted work can block a future home sale, void insurance claims after fire or water damage, and in some cases trigger a forced teardown of completed work if a municipal inspector finds it later.
A good general contractor pulls these permits as part of their scope and schedules inspections at each required stage rather than leaving it to the homeowner. Ask upfront whether permit costs and the time spent on inspections are included in the bid or billed separately, since this is a common place for line-item disputes to surface later.
Living Through the Project Without Losing Your Mind
Whole-home renovations that touch kitchens and bathrooms usually mean losing use of both for weeks at a time. Set up a temporary kitchen with a mini fridge, microwave, and electric kettle in a room that stays protected from dust, and budget for eating out or ordering in more than usual during the demolition and rough mechanical phases. If the bathroom situation gets to the point where you have no working shower in the house, ask your contractor about phasing the bathroom work so one is always functional, even if it means slightly slower overall progress.
Weekly check-in meetings with your contractor, even 15 minutes standing in the driveway, catch small problems before they become expensive ones. Walk the site yourself at least twice a week if you’re living elsewhere during construction.
Start by writing your room-by-room scope list this week, then request bids from at least three licensed, insured general contractors using that same document. Compare not just the total price but the payment schedule, the sequencing plan, and who is responsible for pulling permits. That single document will save you more money and stress than any other step in this process.
