Whole-Home Remodel Cost: A 3,200 sqft Central Valley Example, Pencil to Paper

In the Central Valley in 2026, a cosmetic whole-home refresh runs $200,000 to $400,000. A true gut-and-reconfigure runs $400,000 to $800,000. Add an addition or a second story and the project moves to $800,000 to $1.5 million and beyond. For homeowners remodeling a 3,200-square-foot single-story house in Modesto, Turlock, or Ripon, this article works through the middle tier — the full gut — line by line.

The low end of that band assumes the foundation, roof, and exterior envelope are sound and stay. The high end assumes structural rework and full finish upgrades throughout.

The 3,200 sqft baseline assumption

For the rest of this article, picture a house that sits on half the streets in north Modesto, south Turlock, and central Ripon: a single-story home built between 1962 and 1985. Three bedrooms, two and a half baths, an attached two-car garage, a closed kitchen, a formal living room and a family room, and a small primary suite that was state-of-the-art in 1978 and reads as cramped today. The lot is flat. The plumbing is copper or PEX. The electrical panel is 200-amp and recent. The foundation is a slab in good shape.

From that baseline, a gut-and-reconfigure means: demo to studs throughout, remove one or two non-bearing walls, replace one bearing wall with a steel beam to open the kitchen to the living space, rebuild the primary suite into a real suite, replace all three baths, rebuild the kitchen from scratch, new electrical wiring throughout, new plumbing rough-ins, new HVAC ductwork, new insulation, new windows, new interior doors, new finishes, a new lighting plan, new cabinetry everywhere. The exterior envelope and roof stay.

What does structural work cost in a whole-home remodel?

On the 3,200-square-foot baseline house, structural work runs roughly $28,000 to $42,000 including engineering, steel, and framing labor — the smallest of the big line items. That covers removing the one bearing wall, dropping a steel beam, sistering floor framing where a previous owner cut joists for a fireplace insert, and reinforcing a garage header. Add $25,000 to $60,000 if a small bump-out or a bay reframe is in scope — and note that a real addition pushes the whole project into the tier above.

How much of the budget goes to the kitchen and baths?

Inside the $400K to $800K envelope, the kitchen and three baths together carry $265,000 to $383,000 — roughly half the project on most budgets. A KHB kitchen on this kind of project — custom cabinetry in rift-sawn white oak or painted poplar, a natural-stone counter, a real plaster or metal hood, a layered lighting plan, a mid-tier premium appliance package — runs $145,000 to $210,000 of the total.

The primary bath as a wet-room layout with a freestanding tub, a separate water closet, a shop-built vanity, honed stone counters, tile to the ceiling, and premium plumbing runs $68,000 to $95,000. The two secondary baths together, finished to a slightly lighter spec but still real tile, real stone, and solid-brass plumbing, run $52,000 to $78,000 combined. Add those to the kitchen and you get the concentration of cost that makes per-room budgeting the only honest way to price this work.

How much does finish tier move the rest of the budget?

Outside the kitchen and baths, finish choices move the budget by about $80,000 from the bottom of the range to the top. The variables are: floor type (engineered oak at the low end, fumed solid white-oak plank at the high end), wall finish (paint at the low end, integral-color lime plaster in feature areas at the high end), interior doors (paint-grade solid-core at the low end, custom shaker walnut at the high end), trim profile (a simple two-piece base at the low end, a custom-milled three-piece base with picture rail at the high end), and built-ins (basic at the low end, an entire library wall in white oak at the high end).

None of those finish choices are right or wrong. The right one is the one that matches how long you plan to live there, what the rest of the house calls for, and what you actually look at every day.

What are the soft costs of a whole-home remodel?

The soft costs on a whole-home remodel this size total $68,000 to $121,000: design and construction documents at $42,000 to $65,000; permit fees, plan check, and school fees if you add square footage at $9,000 to $24,000; structural engineering and Title 24 calcs at $4,500 to $9,000; construction-period insurance at $3,000 to $6,000; construction-period electrical and water at $2,500 to $5,000; and dumpsters and disposal across a seven-month project at $7,500 to $12,000.

Those soft costs are real, and they are a real chunk of the gap between an honest quote and a number that looked twenty percent lower at signing but matched ours after change orders. This is the argument for design-build in one sentence: with one team under one contract, every one of those line items is priced during the design phase, on paper, before construction makes the decisions permanent — so the gap never gets a chance to open.

Per-square-foot numbers are useless on whole-home work. The kitchens and the bathrooms carry the budget. Everything else is rounding.

How long does a whole-home remodel take?

On the baseline house with no surprises, a gut-and-reconfigure takes about seven months from demo to substantial completion, plus three to four weeks of punch and closeout. Mid-project additions to scope — a poolhouse, an outdoor kitchen, one more bathroom while the walls are open — are the most common reason a seven-month build becomes nine. Twelve months is the right number to plan for once you add design (three to four months) and pre-construction (six to eight weeks of permits and long-lead orders) to the front. From signed design agreement to handed-over house, a typical client moves back in about thirteen months after they first sit down with us.

What pushes a whole-home remodel past $800K?

Additions are the obvious one — every additional 200 square feet of new conditioned space adds $80,000 to $150,000 at our spec, and a meaningful addition puts the project squarely in the $800,000 to $1.5 million tier. A second story, even a partial one, adds $250,000 to $450,000 plus full structural redesign. Replacing the roof, the siding, or the windows across the entire envelope adds another $90,000 to $180,000. A pool, a poolhouse, a detached studio, or full landscape are separate budgets we keep separate, so they don't hide inside the house number.

The takeaway

$200K to $400K cosmetic. $400K to $800K for a true gut on the 3,200-square-foot single-story baseline. $800K to $1.5M and up once an addition enters the picture. If you are being quoted dramatically less for the same scope, the line items above are not all there — ask which ones, and get the answer in writing. The number you sign for is the number you should be moving back into, give or take change orders for things that genuinely could not be known before demo opened the walls.
