"What's the cost per square foot to remodel a house in Grand Rapids?" It's the most-asked question in remodeling and the single most-misanswered. Most articles give you a national average like "$100 to $200 per square foot" and call it done. That number is useless for budgeting your actual remodel because it averages across project types that don't behave the same way and across neighborhoods that don't price the same way.
This guide does the opposite. We publish a 2026 cross-tab of remodel cost per square foot across six project types (kitchen, bathroom, basement, addition, whole-home, sunroom) and seven West Michigan municipalities (Grand Rapids, Wyoming, East Grand Rapids, Forest Hills, Ada, Cascade, Kentwood). The numbers come from Thornapple Construction's actual fixed-price closes between 2023 and 2026, recalibrated to 2026 supplier pricing. Below the table you'll find a project-by-project deep dive, a methodology section, and a guide to when $/sqft is helpful versus when it will lead you to a bad budget decision.
Why $/sqft Alone Is Misleading
Before the table, a frame-setter. If you walked away from this article remembering only the cross-tab below and not the warning that comes with it, we'd have done you a disservice. Per-square-foot cost is a useful orientation tool. It is a terrible budgeting tool used alone.
Five factors swing the same project's $/sqft by 30% or more in 2026:
1. Project type concentration
Bathrooms and kitchens pack enormous fixture and material density into a small footprint. A 50 sqft hall bath holds a vanity, faucets, tile, waterproofing, glass, lighting, an exhaust fan, plumbing rough-in, and waste lines — divide a $40,000 quote by 50 sqft and you get $800/sqft. The same $40,000 spread across a 1,400 sqft basement finish comes to $29/sqft. Neither number is "wrong." They're measuring different things. The single biggest determinant of remodel $/sqft is which room or project type you're talking about.
2. Scope depth (cosmetic vs. gut)
A kitchen cosmetic refresh — paint, hardware, replace appliances, swap countertops — runs $200/sqft in Grand Rapids. A full kitchen gut with relocated plumbing, new electrical, custom cabinets, and stone counters runs $650/sqft in the same space. Same room. Same square footage. Triple the $/sqft. Scope depth is the second-biggest swing factor and the one homeowners most often underestimate.
3. Municipality
Wyoming and Kentwood — TC's home territory and Kentwood's mid-century housing — sit roughly 10–15% below Grand Rapids historic districts on the same scope. Ada and East Grand Rapids run 15–25% above as finish ambition tracks lot value: homeowners on a $1.4M Ada lot tend to choose custom millwork, designer fixtures, and natural stone where a Wyoming homeowner would choose semi-custom. The remodel is the same scope on paper; the spend per square foot is materially different.
4. Finish ambition
Semi-custom cabinets at $25,000 versus fully custom millwork at $75,000. Quartz at $4,000 versus exotic stone at $18,000. Stock fixtures versus designer brass. Across a kitchen alone, finish ambition can swing total cost by $50,000+, which is $150+/sqft on a typical kitchen footprint. This is the category where Thornapple's design phase earns its keep — we help you spend where it matters and save where it doesn't.
5. Age and condition of the existing house
A pre-1940 home in Heritage Hill or Eastown likely carries knob-and-tube wiring, cast-iron drains, plaster walls over lath, and possibly lead paint or asbestos in floor tile. A 2005 Cascade home has none of those. The remodel scope can look identical on paper while the rough-in and remediation cost differs by $25,000–$60,000. Older housing stock adds 10–25% to $/sqft for the same nominal scope.
The Big Table — 2026 $/sqft by Project × Municipality
Here is the 42-cell cross-tab. Six project types down, seven municipalities across. Numbers are 2026 ranges per finished square foot of the remodeled space (bathroom footprint for bath, kitchen footprint for kitchen, finished basement square footage for basement, addition footprint for addition, total above-grade finished sqft for whole-home, sunroom footprint for sunroom).
| Project Type | Grand Rapids | Wyoming | Kentwood | East GR | Forest Hills | Ada | Cascade |
|---|---|---|---|---|---|---|---|
| Bathroom remodel | $400–$800 | $375–$725 | $375–$750 | $475–$900 | $450–$875 | $500–$950 | $450–$875 |
| Kitchen remodel | $300–$650 | $275–$575 | $275–$600 | $375–$725 | $350–$700 | $400–$800 | $350–$700 |
| Basement finish | $55–$115 | $50–$100 | $50–$105 | $65–$130 | $60–$125 | $70–$140 | $60–$125 |
| Home addition (build-on) | $275–$475 | $250–$425 | $250–$435 | $325–$525 | $300–$500 | $350–$575 | $300–$500 |
| Whole-home remodel | $110–$250 | $100–$235 | $105–$240 | $130–$285 | $125–$275 | $140–$300 | $125–$280 |
| Sunroom (4-season) | $375–$500 | $350–$475 | $350–$475 | $400–$525 | $400–$525 | $425–$550 | $400–$525 |
Lower end of each band corresponds to mid-tier scope with semi-custom finishes. Upper end corresponds to full-gut scope with custom finishes. A cosmetic refresh sits below the lower end (typically 40–60% of the lower number). A bespoke ultra-luxury build can exceed the upper end by 30–50%.
A quick example. If you have a 60 sqft hall bath in Wyoming and you're planning a mid-tier gut, the table says $375–$725/sqft. The mid-point implies roughly $33,000 in total project cost. For a 60 sqft hall bath in Ada at the same mid-tier gut, the table says $500–$950/sqft, implying roughly $43,500. Same room. Same scope. Different municipality, different finish ambition. The full breakdown of what changes between those two quotes is what this guide is about.

Project-by-Project Deep Dive
$/sqft varies more by project type than by anything else. Here's what's actually inside each row.
Bathroom Remodels: $375–$950/sqft
Bathrooms hold the highest $/sqft of any remodel project type because of the density of plumbing, waterproofing, tile, fixtures, and cabinetry packed into 30–150 sqft. A 5x8 hall bath in Wyoming for a mid-tier gut lands at $375–$525/sqft. The same scope in Ada lands at $500–$700/sqft because finishes trend toward natural stone, custom vanities, and designer fixtures.
Luxury primary baths push the top of the range. A 100 sqft primary suite in East Grand Rapids with a custom walk-in shower, freestanding tub, double vanity with stone tops, heated floors, and premium fixtures lands at $750–$900/sqft. The shower glass alone runs $4,000–$8,000; the tile package $8,000–$20,000; the vanity $6,000–$15,000; plumbing rough-in and finish $8,000–$15,000. Add waterproofing, electrical, lighting, paint, and trim, and you understand the $/sqft fast.
For total project ranges by tier (half-bath through luxury primary), see our Grand Rapids bathroom remodel cost guide. For a planning-timeline view, see the bathroom remodel timeline.
Kitchen Remodels: $275–$800/sqft
Kitchens are the second-highest $/sqft and the most decision-rich category in remodeling. Cabinetry alone is typically 25–40% of total kitchen cost — semi-custom at $25,000–$45,000 versus fully custom millwork at $60,000–$120,000 on the same footprint. Countertops are another $4,000–$18,000 swing. Appliances $8,000–$30,000+. Tile, fixtures, lighting, electrical, and trim stack on top.
A 180 sqft mid-tier kitchen gut in Grand Rapids lands at $325–$500/sqft, implying $58,000–$90,000 total. The same kitchen in Ada with custom millwork and a designer appliance package can land at $600–$800/sqft, implying $108,000–$144,000. Open-concept kitchen reconfigurations (removing a wall, relocating plumbing or gas) add a structural premium of $8,000–$20,000 that pushes $/sqft 15–30% higher.
For total project ranges by tier, see our Grand Rapids kitchen remodel cost guide and the open-concept kitchen remodel pros and cons guide.
Basement Finishes: $50–$140/sqft
Basements hold the lowest $/sqft of any indoor remodel project because the structural shell already exists (foundation walls, slab, joists overhead). What you're paying for is framing, insulation, drywall, flooring, lighting, electrical, and finishes spread across 800–1,800 sqft of below-grade space. The $/sqft averages down because the footprint is large and the fixture density is modest.
A basic basement finish — open family room, half bath, simple lighting — lands at $50–$80/sqft. An entertainment basement with wet bar, full bath, theater area, and egress windows lands at $80–$120/sqft. A luxury build-out with kitchenette, custom built-ins, wine room, and high-end finishes lands at $115–$140/sqft. Egress window installation alone runs $3,500–$6,500 (see our basement egress windows guide) and bumps the $/sqft of any project that includes a bedroom requiring code-compliant egress.
For total project ranges, scope tiers, and the moisture-and-code considerations that drive basement budgets, see our Grand Rapids basement remodel cost guide and the basement finishing cost guide.
Home Additions: $250–$575/sqft
Additions sit between bathrooms/kitchens and whole-home remodels on the $/sqft scale because everything is new construction: foundation, framing, roof, exterior siding and windows, full MEP rough-in, insulation, drywall, and finishes. You're not remodeling an existing shell — you're building a new one and tying it into the existing house.
A single-room addition (sunroom, mudroom, primary suite) in Wyoming or Kentwood lands at $250–$400/sqft. The same addition in Ada lands at $350–$500/sqft. Second-story additions push 15–30% higher because the existing foundation and first-floor structure must be reinforced before the new floor can sit on top. Multi-room additions and bump-outs that integrate with the existing roofline carry a tie-in premium of $5,000–$15,000 to make the addition read seamlessly from the street.
For total project ranges by addition type, see our home addition cost guide, the home addition cost guide blog, the two-story addition cost guide, and our analysis of home addition vs. moving.
Whole-Home Remodels: $100–$300/sqft
Whole-home remodel $/sqft is the lowest of any indoor remodel project — but for a counterintuitive reason. The total project budget is the highest of any category (a Tier 4 full gut to studs runs $425,000–$550,000), but it's spread across 2,000–4,000 sqft of finished space. The dense-spend areas (kitchen and bathrooms) get averaged with the low-spend areas (hallways, bedrooms, common areas) where fixture and tile density is low.
A whole-home cosmetic refresh in Wyoming lands at $100–$135/sqft. A mid-tier renovation in Grand Rapids lands at $130–$175/sqft. A full gut in Ada lands at $215–$300/sqft. A gut-plus-addition in East Grand Rapids can push past $300/sqft once you stack a 400 sqft primary suite addition with custom finishes onto a 2,400 sqft existing footprint.
The whole-home page on this site publishes the per-municipality $/sqft band by scope tier (refresh, mid, premium, luxury) and the six-tier project ladder from $150K refresh to $750K+ estate-level. For the full breakdown, see our whole home remodel cost Grand Rapids guide and our 2026 remodeling cost report.
Sunrooms (Four-Season): $350–$550/sqft
Sunrooms carry their own $/sqft band because of the engineered glass packages, frost-protected foundations, and HVAC integration required for year-round use. A three-season sunroom (no HVAC, double-pane Low-E glass, mini-split or none) runs $200–$300/sqft in West Michigan. A four-season sunroom with full HVAC tied into the main system, triple-pane glass, and a frost-protected foundation runs $350–$500/sqft.
Integrated room additions with sunroom features — built to read as part of the original house from the street, with matching roofline and siding — sit at the upper end ($450–$550/sqft) because of the tie-in detailing. The Ada and East Grand Rapids markets trend toward integrated builds; Wyoming and Kentwood projects more often choose three-season builds with optional HVAC upgrades later.
For total project ranges and three-season vs. four-season decision criteria, see our sunroom addition Grand Rapids guide and the sunroom addition cost guide.
Methodology — Where These Numbers Come From
Most cost-per-square-foot articles online don't tell you where their numbers come from. Here is how we built the cross-tab above.
Source 1: TC fixed-price closes, 2023–2026
Thornapple Construction operates on fixed-price contracts, which means every project closes with a known final number tied to a known scope. We pulled the actual close prices on every bathroom, kitchen, basement, addition, whole-home, and sunroom project completed between January 2023 and April 2026 across all seven municipalities listed. We divided each project's close price by the finished square footage of the remodeled space and grouped by project type and municipality. The midpoint of each band reflects the mid-scope variant; the lower end reflects cosmetic-leaning scope; the upper end reflects full-gut or luxury scope with custom finishes.
Source 2: 2026 supplier pricing
2023–2025 close prices were recalibrated to 2026 supplier pricing. Cabinetry, tile, fixtures, lumber, drywall, paint, and labor rates have all moved between 2023 and 2026 — some up, some flat. We applied current 2026 unit pricing on every major line item to make the numbers in the table reflect what a new project signed in May 2026 would actually quote at. Projects that closed in 2023 at materially different prices were not used as-is; they were adjusted to current pricing or excluded.
Source 3: Municipality calibration
The seven municipalities don't have identical labor rates, permit costs, or housing stock. Wyoming and Kentwood reflect TC's home market and the bulk of our closes. Grand Rapids historic districts (Heritage Hill, Eastown, Creston) carry a hidden-conditions premium for pre-1940 stock that adds 10–25% to the same scope. Ada, East Grand Rapids, and Forest Hills carry a finish-ambition premium of 15–25% as customer expectations track lot value. Cascade sits close to Forest Hills with a slightly smoother township permit flow.
What's not in the numbers
The table excludes: hidden-conditions overruns (we absorb these inside our fixed-price contracts because they're our risk to manage, not yours), homeowner-driven change orders mid-build, and exterior or landscape work bundled with whole-home projects. For the full list of cost categories that go into a remodel, see our 2026 remodeling cost report.
When $/sqft Is Helpful — and When It's Misleading
$/sqft is a useful number when used correctly. It is dangerous when used as the only budgeting input.
When it's helpful
- Sanity-checking a quote. If a contractor quotes your 60 sqft Wyoming bathroom at $50,000 ($833/sqft), the cross-tab tells you that's above the Wyoming range — fair questions to ask are whether the finish package is luxury-tier and whether the existing house has hidden conditions inflating the quote.
- Translating square footage to a budget range. If you know your kitchen is 180 sqft and you live in Grand Rapids, $300–$650/sqft implies $54,000–$117,000 total. You can then look at the kitchen cost-guide tiers and decide which scope tier matches your goal.
- Comparing project types. A 300 sqft addition versus a 100 sqft bath remodel: the addition will cost roughly 2–3x more in total but actually less per square foot. Useful when you're choosing between expanding versus renovating.
- Identifying neighborhoods that fit your budget. If you're house-shopping and a renovation is part of the calculus, the cross-tab tells you that the same renovation in Wyoming will run 15–25% less than in Ada — useful for total-cost-of-ownership math.
When it's misleading
- As the sole basis for budgeting. $/sqft is an average. Your project is a specific scope in a specific house. Use a detailed estimate or a fixed-price contract for your actual budget number.
- Across project types. Comparing kitchen $/sqft to whole-home $/sqft is meaningless — they measure different spend densities. Stay within a project type when using the number.
- For ultra-small or ultra-large projects. A 20 sqft powder room and a 200 sqft primary bath behave very differently — fixed costs (permits, mobilization, demo protection) dominate the small projects, while finish ambition dominates the large ones. Both distort the $/sqft.
- For homes with unusual conditions. A foundation in distress, severe water damage, asbestos remediation, or significant electrical or HVAC replacement can add $20,000–$80,000 to a project — none of which is captured in a generic $/sqft band.
- When the contractor is using "estimate" instead of "contract." A contractor's $/sqft estimate is a guess. A fixed-price contract is a commitment. Compare the numbers in this table to a fixed-price contract, not to a ballpark "from $150/sqft" line.
Estimate vs. Fixed-Price Contract
Most remodelers in West Michigan quote remodels as "estimates" with a built-in allowance structure for finishes, fixtures, and unforeseen conditions. The number you see in the proposal is rarely the number you pay — change orders, allowance overruns, and "we found something behind the wall" add-ons typically push the final number 15–40% above the original estimate.
Thornapple Construction works on fixed-price contracts. The quote we deliver after the design phase is the price you pay for the agreed scope, with the only adjustments being owner-directed change orders that you initiate and approve in writing. We absorb the risk of hidden conditions because that's our job to assess during the design phase. The $/sqft numbers on this page are derived from those fixed-price closes — they reflect what homeowners actually paid, not what was originally estimated.
Read more about how the design-first, fixed-price model works on our process page, or see the contract-vs-estimate framing on the whole home remodel cost page.
How to Use This Table in Your Planning
Three steps.
- Identify your project type and municipality. Find your cell in the table. Note the range.
- Estimate your scope depth. Cosmetic-leaning sits below the lower number (40–60% of it). Mid-tier sits at the midpoint. Full gut or luxury sits at the upper number. Custom or bespoke can exceed the upper number by 30–50%.
- Multiply by your square footage to get an orientation range. Then use our cost estimator to narrow that range, and use a discovery call to get a fixed-price quote on the actual scope.
For a worked example: a homeowner in Forest Hills planning a mid-tier 180 sqft kitchen gut. Forest Hills kitchen row: $350–$700/sqft. Mid-tier midpoint: $525/sqft. Implied total: $94,500. That's the orientation number. The cost estimator will narrow it; the discovery call will lock it.
Frequently Asked Questions
What is the average remodel cost per square foot in Grand Rapids in 2026?
There is no single answer because $/sqft swings dramatically by project type. In 2026, bathroom remodels in Grand Rapids run $400–$800/sqft, kitchens $300–$650/sqft, basement finishes $55–$115/sqft, home additions $275–$475/sqft, whole-home remodels $110–$250/sqft, and four-season sunrooms $375–$500/sqft. Municipality shifts each band: Wyoming and Kentwood sit roughly 10–15% below Grand Rapids; East Grand Rapids, Forest Hills, Ada, and Cascade sit 15–25% above as finish ambition tracks lot value.
Why is bathroom cost per square foot so much higher than whole-home cost per square foot?
Bathrooms pack enormous spend density into a tiny footprint. A 50 sqft bathroom can hold a $7,000 vanity, $4,000 of tile, $3,500 in fixtures, plumbing rough-in, waterproofing, glass, electrical, and finishes — divide $40,000 by 50 sqft and you get $800/sqft. Whole-home remodels spread the same kinds of finishes across hallways, bedrooms, and common areas where fixture density is low, so the $/sqft averages down. The $/sqft number is essentially a measure of spend density, not a measure of quality or efficiency.
How much does it cost per square foot to add an addition to a house in Michigan?
In West Michigan, home additions run $250–$575/sqft in 2026 depending on municipality and finish level. Single-room additions and primary suite additions are typically $275–$475/sqft in Grand Rapids and Wyoming, $325–$525/sqft in East Grand Rapids and Forest Hills, and $350–$575/sqft in Ada. Second-story additions push 15–30% higher because the existing foundation and first-floor structure must be reinforced. The $/sqft is high relative to whole-home remodel $/sqft because the addition includes new foundation, framing, roof, and full MEP — items the existing house already has.
Is $100 per square foot a realistic remodel budget in Grand Rapids?
$100/sqft is realistic for basement finishing in Wyoming or Kentwood and for whole-home cosmetic refreshes in lower-cost municipalities. It is not realistic for any kitchen, bathroom, addition, or sunroom remodel — those project types start at 2.5x to 4x that number because of fixture and material density. If a contractor quotes $100/sqft for a kitchen or bath in 2026, the quote is either incomplete (missing scope items that will surface as change orders), or the contractor is undercutting price to win the job and intends to make it up through change orders mid-build.
Why does the cost per square foot vary by neighborhood in Grand Rapids?
Three reasons. First, housing stock: Grand Rapids historic districts (Heritage Hill, Eastown, Creston) have pre-1940 homes with knob-and-tube wiring, plaster walls, and cast-iron drains that add hidden-condition costs. Second, finish ambition: in Ada, East Grand Rapids, and Forest Hills, remodel finish levels track lot values, so homeowners often choose custom millwork, premium fixtures, and natural stone — the same kitchen square footage costs more because of what's installed in it. Third, permit and municipal differences: townships like Cascade and Ada have faster permitting than the City of Grand Rapids, which can affect timeline and indirectly schedule premium.
How is cost per square foot calculated for a remodel?
Total project cost divided by finished square footage of the remodeled space. For a bathroom, that's the bathroom footprint only. For a whole-home remodel, it's the total above-grade finished square footage of the house. For an addition, it's the new addition footprint (not including the existing home). The number is useful as a sanity check on a quote and as a way to translate between square footage and total budget, but it should never be the sole basis for deciding whether a quote is reasonable. Scope depth, finish ambition, and house condition each move the number by 30–50%.
When is per-square-foot cost a misleading way to budget a remodel?
Whenever it's used as the sole budgeting input. $/sqft averages mask the four factors that actually drive your specific quote: project type concentration (bath/kitchen fixtures pack expense density), scope depth (cosmetic vs. full gut shifts the number by 3x), finish ambition (semi-custom vs. fully custom can double it), and the age and condition of your existing house (hidden conditions in pre-1940 stock add 10–25%). Use $/sqft for orientation — to know if a quote is in the right neighborhood. Use a detailed scope-by-scope estimate, ideally a fixed-price contract, for actual budgeting.
