Home Remodel ROI — Costs and Resale Value for Boise Homeowners
What remodeling actually costs in the Treasure Valley, which projects tend to hold their value, and where the published cost-recovery research does — and does not — apply to a Boise home.
Quick answer
We do not publish a Boise-specific ROI ranking, because no one measures cost recovery at the Ada County level and we do not have resale data on the homes we have worked on.
Remodeling ROI measures how much of your project cost you recover when you sell your home. A $50,000 kitchen remodel that adds $35,000 to your sale price delivers a 70% return. No remodeling project consistently returns 100% of its cost — but that does not mean the investment is wasted. The gap between cost and recovered value is the price of enjoying the improvement while you live in the home.
This guide does not publish a recovery percentage for Boise. The published research that does — Remodeling magazine's annual Cost vs. Value Report and the National Association of REALTORS Remodeling Impact Report, both linked at the foot of this page — reports by broad region, not by Treasure Valley neighborhood, and we have no resale data of our own on the homes we have worked on. Rather than dress a national figure up as a local one, what follows is the cost side, which we can source: what each project runs here, and what actually moves the number.
Resale is also only part of the picture. It does not include lifestyle value (daily comfort, reduced frustration), energy savings (lower utility bills), or avoided costs (not having to move to get the features you need). For long-term Boise homeowners, these non-financial returns often outweigh the resale math.
What you spend versus what you recover at resale — the core ROI calculation.
Recent comparable sales on your street cap what any remodel can return.
Daily comfort and functionality gains that ROI percentages cannot capture.
This guide lists what each major remodeling project costs in Boise, then breaks them into budget tiers so you can see what a given budget buys. See our Boise remodel ROI overview for a condensed summary, or dive into the full rankings below.
The table below is our published Boise cost band for each service we perform, together with the factor that moves a given project within that band. These are quoting ranges, not survey averages. There is no resale-recovery column because we do not have sourced recovery data for Ada County, and inventing one would be worse than leaving it out.
| Project | Boise Cost Range | Most Projects Land At | What Moves the Number |
|---|---|---|---|
| Interior painting | $1,800–$14,000 | $4,200 | Prep: plaster repair and skim-coating in older homes is added scope, not faster work |
| Exterior painting | $2,800–$18,000 | $6,500 | Story count, siding condition, wood rot repair, and stripping failing coatings |
| Flooring replacement | $3,500–$32,000 | $9,800 | Material tier (LVP vs. engineered hardwood vs. tile) and subfloor preparation |
| Window replacement | $6,500–$28,000 | $13,500 | Window count, frame material, and custom sizing for pre-war rough openings |
| Shower remodel | $8,500–$35,000 | $17,500 | Tile format, glass enclosure type, and substrate remediation found at demo |
| Siding replacement | $8,500–$32,000 | $16,500 | Home size, second-story scaffolding, and trim detail on historic elevations |
| Bathroom remodel | $12,000–$95,000 | $25,000–$45,000 | Whether plumbing moves, and what the older housing stock hides behind the walls |
| Deck addition | $18,000–$95,000+ | $32,000–$55,000 | 24-inch frost-depth footings, elevation, and decking material |
| Kitchen remodel | $22,000–$145,000 | $45,000–$70,000 | Cabinet tier, whether walls come out, and appliance and countertop specification |
| Home addition | $60,000–$400,000+ | $145,000 | Foundation, roofline tie-in, and whether the existing structure needs reinforcement |
| Whole-home remodel | $85,000–$350,000+ | $145,000–$195,000 | Cosmetic refresh versus structural: walls, plumbing stacks, panel, and HVAC |
| ADU | $95,000–$320,000 | $165,000 | Conversion versus new build, and the distance to existing utility connections |

The most cost-efficient remodeling work in Boise shares a common trait: it delivers outsized visual impact relative to its cost. These projects change how a house reads — at the kerb and in listing photos — without structural complexity, permitting requirements, or extended timelines. For homeowners selling within one to three years, this is where a limited budget does the most visible work.
Exterior Painting ($2,800–$18,000; most projects near $6,500)
A fresh exterior paint job is one of the fastest ways to reset buyer perception, and a peeling or chalked exterior reads as deferred maintenance. Boise’s summer UV load and its freeze-thaw cycling — the city averages 87 freeze-thaw cycles a year (30-year mean, KBOI ASOS 1996–2025 via the Iowa Environmental Mesonet) — are hard on a coating, so the premium systems and full prep are the job, not an upsell. Our $6,500 reference project is a two-story, 2,200-square-foot home with lap siding in fair-to-good condition, fully prepped, primed, and given two topcoats.
Read full ROI analysisInterior Painting ($1,800–$14,000; most projects near $4,200)
A whole-house repaint of walls, ceilings, trim, and doors is the cheapest way to make every room in a house read as maintained. Most of the cost is labour and most of the labour is prep, which is why a North End or Bench home costs materially more than a same-size newer house: plaster repair, skim-coating, and bonding primer are added scope rather than a faster version of the same work.
Read full ROI analysisFlooring Replacement ($3,500–$32,000; most projects near $9,800)
Consistent flooring across an open plan is one of the few changes that reads as higher quality to nearly every buyer. LVP runs $4–$8 per square foot installed in Boise and engineered or solid hardwood $8–$18, so the whole-home number is set mostly by material tier and by how much subfloor preparation the house turns out to need.
Read full ROI analysisShower Remodel ($8,500–$35,000; most projects near $17,500)
A dated fiberglass tub-surround is the single most common complaint we hear about Boise’s 1970s–1990s housing stock. A tub-to-shower conversion with a properly waterproofed pan, tiled walls, and a semi-frameless enclosure typically runs $8,500–$14,000 — a contained scope that changes the room without touching the rest of the bathroom.
Read full ROI analysisSiding Repair and Partial Replacement
Full re-siding starts at $8,500 and runs to $32,000, but localised work — replacing failed sections, rebuilding trim, and repainting — sits well below that and removes the visual cue buyers read as neglect. If your home is in the City of Boise hillside area or Wildland Urban Interface, note that the Fire Prevention Code requires non-combustible siding there: fiber cement qualifies, and LP states its SmartSide engineered wood is Class C (Class III) under ASTM E84 and is not an ignition-resistant material under IWUIC Section 503.2.
Read full ROI analysisThe $25,000–$75,000 range covers the mid-range renovations that buyers weight most heavily during showings and appraisals. At this budget, you can fully transform a single major room or upgrade an entire exterior system. Cost recovery as a percentage tends to fall as project size rises — that is the consistent finding across the national cost-vs-value research — while the total dollars added to the home rise. Which of those you optimise for is the real decision at this tier.
Kitchen Remodel
$45,000–$70,000 — Where most land
Semi-custom cabinets, quartz countertops, a modest island addition or expansion, new appliances, LVP flooring, and a new backsplash. On-site construction on a kitchen of this scope runs one to two weeks, with demo held until cabinets and appliances are on site.
Full ROI breakdownBathroom Remodel
$25,000–$45,000 — Where most land
Full demo, a tiled shower surround with a frameless glass enclosure, new vanity and countertop, tile or LVP flooring, updated lighting, and quality fixtures. In Boise’s older housing stock, budget for what demo uncovers — galvanised supply, subfloor repair, and asbestos testing are discovery items here more often than homeowners expect.
Full ROI breakdownSiding Replacement
$8,500–$32,000 — Typical: $16,500
Installed prices in Boise run about $5–$10 per square foot for vinyl, $8–$13 for LP SmartSide engineered wood, and $10–$16 for James Hardie fiber cement. In Boise, HZ5 is the correct Hardie climate line. The City issues re-siding under Permit 428, priced from declared project value on the adopted fee schedule.
Full ROI breakdownWindow Replacement
$6,500–$28,000 — Typical: $13,500
Builder-grade double-pane Low-E vinyl runs $300–$500 per window installed; the premium welded-corner vinyl we specify runs $500–$900; fiberglass runs $550–$950. A 20-window replacement on a typical Boise ranch or two-story lands at $6,000–$10,000 in builder-grade vinyl and $10,000–$18,000 in premium vinyl.
Full ROI breakdownDeck Addition
$32,000–$55,000 — Where most land
A deck extends living space outdoors, and in Boise every footing has to reach the 24-inch design frost depth, which is more excavation and concrete than a shallow-frost market needs. Cedar and pressure-treated lumber remain the most cost-effective decking; note that composite and PVC boards are combustible and are not a WUI substitute for non-combustible construction.
Full ROI breakdownWhole-Home Flooring
$3,500–$32,000 — Typical: $9,800
Luxury vinyl plank or engineered hardwood throughout main living areas. Across 2,000 square feet, quality LVP works out to roughly $8,000–$16,000 and engineered hardwood to roughly $16,000–$32,000. Consistent flooring across an open plan reads as higher quality than mixed materials.
Full ROI breakdownWhy the Mid-Range Tier Is Where Most Projects Sit
Our own quoting bands cluster here: the average Boise kitchen remodel runs $45,000–$70,000, the average bathroom $25,000–$45,000, the average deck $32,000–$55,000. That is not a statement about resale — it is simply where the scope most homeowners want and the price of doing it properly meet.
The mid-range tier also avoids the neighborhood ceiling problem that catches premium renovations. A kitchen finished to the level of the rest of your street is priced by the comps. One finished well above it is paid for by you. Before you settle a budget, have an agent pull recent comparable sales within a few blocks and look at what those kitchens actually contained.
Large projects are consistently the weakest performers as a percentage of cost and the strongest in total dollars added. They also provide the greatest lifestyle transformation — a factor that matters enormously for homeowners planning to live in the home for five or more years. At this size the recovery percentage only tells half the story: the other half is whether the investment lets you stay in a home you love instead of paying to move.
Full Kitchen Gut ($85,000–$145,000)
Custom cabinetry, natural stone or premium quartz countertops, professional-grade appliances, layout reconfiguration with wall removal and structural beams, and high-end lighting. This is the top of our published Boise band and it is the scope that justifies it — not a finish upgrade on the mid-range scope, but a different project.
Full ROI analysisRoom Addition ($60,000–$400,000+; most projects near $145,000)
An addition buys usable space the existing footprint cannot provide. A ground-floor bump-out runs $60,000–$90,000 fully finished; a full room addition with its own foundation, framing, and roofline tie-in falls in the $95,000–$160,000 range; a second story over an existing ranch runs $180,000 to $400,000+ depending on whether the structure below needs reinforcement. Every new footing has to reach the 24-inch design frost depth.
Full ROI analysisADU / Accessory Dwelling Unit ($95,000–$320,000; most projects near $165,000)
Boise allows an ADU of 900 square feet or 70% of the primary dwelling, whichever is less, with a maximum of two bedrooms and two stories, and setbacks that follow the underlying zone. A garage conversion runs $95,000–$145,000; a new detached 600-square-foot one-bedroom unit runs $145,000–$220,000. We do not publish a rental-income figure or a payback period, because we do not have a sourced Boise rent series to base one on — use your own market research for the income side.
Full ROI analysisWhole-Home Remodel ($85,000–$350,000+; most projects $145,000–$195,000)
A comprehensive renovation touching kitchen, bathrooms, flooring, lighting, paint, and potentially structural elements. The range is wide because allocation matters more than total spend: a cosmetic refresh and a renovation that removes load-bearing walls, relocates plumbing stacks, and upgrades the panel to 200-amp service are different projects at the same address.
Full ROI analysisWhen a Lower Recovery Percentage Still Makes Sense
A modest percentage of a large number can still be a larger number than a high percentage of a small one. For homeowners who need more space or fundamentally different functionality, the recovery percentage is less important than the absolute value increase and the cost of the alternative — moving.
Run that comparison with your own figures rather than a rule of thumb. Ask your agent what your home would list for today, what it would list for with the work done, and what the full cost of selling and buying again would be — commission, closing costs, moving, and the difference in your mortgage rate. Compare that total against the quoted cost of the renovation. We publish a cost for our half of that equation; nobody can publish yours.
National cost-recovery research provides a starting point, but five Treasure Valley dynamics bear on what a remodel is worth here. None of them can be reduced to a percentage we could source, so they are described rather than quantified.
Neighborhood Price Ceiling
Every Boise neighborhood has an implicit value ceiling set by comparable sales. Over-improving beyond that ceiling means you cannot recover the excess investment regardless of quality. We deliberately do not publish per-neighborhood price bands here: we have no licensed source for Ada County sale prices, and a band that is a year stale is worse than none. Ask an agent to pull sold comparables within a few blocks of your address, filtered to homes of your size and age, and read the ceiling off real sales rather than off a contractor's table.
In-Migration Buyer Demographics
Buyers relocating from Portland, Seattle, San Francisco, and Los Angeles are accustomed to modern finishes — quartz countertops, walk-in showers, open-concept layouts, and quality cabinetry. In our experience quoting here, that expectation shows up in what buyers ask about. We have not measured the premium it produces and will not publish a figure for it — treat it as a reason to expect updated homes to compete well, not as a number to underwrite a budget with.
Housing Stock Age and Inventory
Boise's housing stock is dominated by 1990s–2010s construction with oak cabinets, laminate countertops, fiberglass tub/showers, and builder-grade fixtures. These homes are structurally sound but aesthetically dated — the ideal candidate for mid-range remodeling. In established neighborhoods where new construction is limited (North End, Bench, East End), updated existing homes face less competition from new builds, which further supports remodel ROI.
The Building Season
The constraint we can speak to is the building season, not the selling season. Interior work runs year-round. Exterior work — siding, painting, decks, window openings — is weather-bound: Boise's January mean low is 25.9°F and the city averages 87 freeze-thaw cycles a year (30-year mean, KBOI ASOS 1996–2025 via the Iowa Environmental Mesonet), which rules out coatings and some concrete work for part of the year. If you intend to list, work backwards from the exterior window, because that is the part of the schedule that cannot be compressed.
Wildland-Urban Interface (WUI) Compliance Value
Portions of Boise's hillside area fall within the wildland-urban interface, and there the material choice is not a preference. Under City of Boise Permit 428, roof coverings and siding installed in the hillside area or the WUI must be non-combustible as regulated by the Boise Fire Prevention Code. Fiber cement qualifies. Standard vinyl and wood do not, and LP states its SmartSide engineered wood is Class C (Class III) under ASTM E84 and is not an ignition-resistant material under IWUIC Section 503.2 — so it is not a WUI substitute either. Composite and PVC decking is combustible as well. We do not publish an insurance-premium figure for compliant construction; ask your carrier, because the answer is carrier-specific.
What home remodel project has the highest ROI in Boise?
We do not publish a Boise-specific ROI ranking, because no one measures cost recovery at the Ada County level and we do not have resale data on the homes we have worked on. The two organisations that do publish cost-recovery research are Remodeling magazine (the annual Cost vs. Value Report, reported by region rather than by Boise neighborhood) and the National Association of REALTORS (the Remodeling Impact Report); both are linked at the foot of this page and both should be read at the source rather than paraphrased by a contractor. What we can give you with confidence is the cost side: what each project actually runs in the Treasure Valley, quoted from the work we do here. The qualitative pattern those national reports share is that modest, high-visibility exterior work recovers a larger share of its cost than a large interior renovation, while the large renovation adds more total dollars. Which of those matters to you depends on your neighborhood's price ceiling and how long you plan to stay.
How much does a full kitchen remodel cost in Boise?
A cosmetic-to-mid-range refresh — new cabinets, quartz countertops, LVP flooring, and updated fixtures without structural changes — runs $22,000 to $38,000. The range most Boise homeowners actually land in is $45,000 to $70,000: a comprehensive remodel with semi-custom cabinets, quartz countertops, a modest island addition or expansion, new appliances, flooring, and a backsplash. A full gut with wall removal, structural beams, custom cabinetry, and premium appliances and countertops in a larger kitchen runs $85,000 to $145,000. Those are our published Boise ranges, not a national average. What we will not tell you is what share of any of them comes back at resale — that figure depends on your neighborhood's comparable sales and the condition of the homes you are selling against, and no published table captures it for a specific Boise street.
Is it worth remodeling if I plan to stay in my Boise home for 10+ years?
For a long stay, weight lifestyle value more heavily than resale recovery. The daily comfort and functionality you get from an updated kitchen, bathroom, or outdoor living space accumulates over a decade in a way that a cost-recovery percentage cannot capture, and a percentage measured at a sale you are not going to make is not a number you can spend. The practical sequence for homeowners staying put is to fix the things that frustrate you daily first — a cramped kitchen, a single outdated bathroom, a cold or draughty envelope — and leave resale-focused cosmetic work until a sale is a realistic timeline item, because finishes chosen eight years early will read as dated by the time they matter.
Does Boise's housing market change what a remodel is worth?
Almost certainly, but we have not measured it and we will not publish a number we cannot source. Local conditions that plainly bear on resale are visible without a statistic: the Treasure Valley has drawn sustained in-migration from higher-cost West Coast markets, much of Boise's housing stock is structurally sound 1990s–2010s construction with dated interiors, and new-build inventory inside established neighborhoods such as the North End, the Bench, and the East End is limited. Each of those argues that updated homes compete well here. None of them supports a specific premium expressed in percentage points, and any contractor who quotes you one for Boise is estimating. If you want a defensible figure for your own home, ask a local agent to pull comparable sales for updated and un-updated homes on your block — that is the only data that reflects your actual market.
How do I avoid over-improving a Boise home?
Compare your project's finished scope to what comparable homes in your immediate neighborhood already include, not to what you have seen online. Every neighborhood carries an implicit value ceiling set by recent sales, and spending past that ceiling is the single most reliable way to lose money on a remodel — a kitchen finished well above everything else on the street is paid for by you and priced by the comps. Two other categories deserve caution in Boise specifically. Removing a feature buyers expect, such as converting an attached garage to living space without replacing the parking, narrows your buyer pool. So does a highly personal buildout — a specialised home gym, a purpose-built studio — which serves your use rather than a broad expectation. Neither is a bad decision if you are staying; both are a risk if you are selling within a few years.
