Open Concept Kitchen Remodel in Boise, Idaho
Remove walls, open sight lines, and create the kitchen-living space your family actually uses
Open concept kitchen remodels have dominated Boise's remodeling market for the past decade — and demand is still accelerating. The National Association of Home Builders consistently ranks open layouts as the most-requested feature in both new construction and renovation projects, and the Treasure Valley is no exception. Homeowners are tearing down the walls that separate their kitchens from living rooms, dining areas, and family spaces.
The reasons are both practical and cultural. Boise families spend more time at home than ever — remote work, home cooking, and family-centered lifestyles have made the kitchen the true center of the house. A closed-off galley or U-shaped kitchen tucked behind a wall means the cook is isolated from conversations, homework supervision, and everyday family activity. Removing that wall transforms daily life immediately.
From a real estate perspective, open concept layouts are no longer a luxury preference — they are a market expectation. Boise buyers in the $350,000–$700,000 range consistently rank open kitchens as a top-three priority. Homes with closed-off kitchens sit longer on the market, and agents frequently recommend wall removal as the single highest-impact improvement a seller can make before listing. The Treasure Valley's housing stock — packed with 1970s ranch homes, 1990s split-levels, and early 2000s colonials with segmented floor plans — provides an enormous pool of candidates for open concept conversions.
Iron Crest Remodel has completed open concept kitchen transformations throughout Boise, Meridian, Eagle, Nampa, and the surrounding Treasure Valley. We handle every phase: structural assessment, engineering, permits, wall removal, beam installation, and the full kitchen renovation that follows. This guide covers what the project involves, what it costs, and how we approach it.
The single most important question in any open concept kitchen remodel is whether the wall you want to remove is load-bearing. A load-bearing wall carries the weight of the structure above it — roof loads, second-floor loads, ceiling joists — down through the framing to the foundation. Removing it without installing a replacement support system can cause catastrophic structural failure: sagging ceilings, cracked drywall, misaligned doors, and in worst cases, partial collapse.
Here are the indicators we look for during our initial assessment:
Joist Direction
If ceiling joists run perpendicular to the wall (crossing over it), the wall is likely load-bearing. If joists run parallel to the wall, it may be a partition wall — but this alone is not conclusive. In many Boise homes, particularly ranch-style and split-levels, the main load-bearing wall runs down the center of the house parallel to the ridge line.
Below the Wall
We inspect the crawl space or basement directly beneath the wall. If there is a beam, footing, or support wall below the wall in question, it is almost certainly load-bearing. The foundation was designed to carry the concentrated load from that wall down to the footing. Boise's common crawl space construction makes this inspection straightforward in most homes.
Wall Location and Stacking
Walls near the center of the home, walls that stack directly above each other on multiple floors, and exterior walls are almost always load-bearing. In two-story Boise homes, the wall between the kitchen and living room on the main floor often supports the second-floor hallway and bedroom partition walls above it.
Original Blueprints
If available, original construction drawings identify load-bearing walls. Ada County may have copies of the original building plans on file for homes permitted after the mid-1970s. We request these during the assessment phase when they are available.
Important: Visual indicators are starting points — not conclusions. We never advise removing a wall based on visual inspection alone. Every wall removal project requires a licensed structural engineer to assess loads, design the replacement support system, and produce stamped plans that Ada County will approve for a permit. This is not optional — it is a code requirement and a safety necessity.
Once we determine that a wall is load-bearing, a licensed structural engineer takes over the design of the replacement support system. This is the most critical technical phase of the project. Here is what the engineering process involves:
Load Analysis
The engineer calculates the total load the wall currently carries. This includes dead loads (the weight of the structure itself — roof sheathing, roofing materials, ceiling joists, subfloor, second-story framing if applicable) and live loads (occupant weight, furniture, snow load on the roof). In Boise, the ground snow load is 25 pounds per square foot per the International Building Code, which factors into the beam sizing calculation.
Beam Sizing and Material Selection
Based on the load analysis and the span length (the distance the beam must cover without intermediate support), the engineer specifies the beam dimensions and material. Short spans (8–12 feet) may use engineered LVL beams. Longer spans (12–20+ feet) typically require steel I-beams. The beam must also fit within the available ceiling depth — dropping a beam below the ceiling line is sometimes necessary but is avoided when possible to maintain clean sight lines.
Post and Footing Design
The beam transfers the load to posts at each end (and sometimes at intermediate points for very long spans). Those posts must sit on adequate footings — the foundation must be capable of carrying the concentrated point load. In many Boise homes with crawl space foundations, new concrete pier footings are poured beneath the post locations. The engineer specifies footing dimensions and reinforcement based on the soil conditions and load.
Connection Details
The engineer designs the connections between the beam, posts, and existing framing. Steel beams require welded or bolted bearing plates. LVL beams use Simpson Strong-Tie connectors or custom steel brackets. The connections must transfer load without crushing the wood fibers or allowing lateral movement. These details are specified on the stamped plans and inspected during construction.
Stamped Plans for Ada County
The engineer produces stamped structural drawings — signed and sealed by a licensed Professional Engineer (PE) registered in Idaho. These plans are submitted with your building permit application to Boise's Planning & Development Services. Ada County reviews the engineering and issues the structural permit. The stamped plans must be on-site during all inspections. Engineering fees for a typical wall removal in Boise run $1,500–$3,500 depending on complexity.
The structural component — removing the wall and installing the replacement beam system — is a distinct cost from the kitchen renovation that follows. Here is what the wall removal phase alone typically costs in the Boise market:
Structural wall removal range: $5,000 – $20,000+
Most common projects (single wall, standard span): $8,000 – $14,000
Structural Engineering
$1,500–$3,500Licensed PE site visit, load calculations, beam and footing design, stamped plans for permit submission. Cost increases for two-story homes, multiple walls, or unusual structural configurations.
Temporary Shoring and Demolition
$1,000–$3,000Temporary support walls or adjustable steel posts are erected on both sides of the load-bearing wall to carry the load while the wall is removed and the permanent beam is installed. The existing wall is then carefully demolished, preserving any electrical, plumbing, or HVAC components for relocation.
Beam and Post Installation
$2,500–$8,000Material cost for the beam (steel I-beams cost more than LVL), posts, bearing plates, and connectors. Labor for lifting and setting the beam (steel beams often require a crane or boom), securing connections, and verifying alignment. Includes new pier footings in the crawl space if required.
Electrical, Plumbing, HVAC Relocation
$1,000–$5,000+Most interior walls contain at least electrical wiring — outlets, switches, and circuits that must be rerouted. Kitchen walls often contain plumbing supply and drain lines, and sometimes HVAC ductwork. Each system that runs through the wall adds relocation cost and may require its own permit and inspection.
Drywall, Ceiling, and Floor Patching
$1,000–$3,000After the beam is installed and hidden within the ceiling cavity (or boxed out below if a flush installation is not possible), the ceiling, floor, and adjacent walls are patched, textured, and painted to match the surrounding surfaces. Matching existing textures — particularly older popcorn or knockdown textures — requires skilled finishing.
Most homeowners do not stop at wall removal — the open concept conversion is paired with a full kitchen renovation. Once the wall is down and the space is open, it makes practical and financial sense to upgrade the kitchen at the same time. Here is what a complete open concept kitchen remodel costs in the Boise market:
Full open concept kitchen remodel: $35,000 – $100,000+
Most common projects in Boise: $50,000 – $75,000
Budget-Conscious Open Concept
$35,000–$50,000Single wall removal with standard beam, stock or semi-custom cabinets, laminate or butcher block countertops, standard appliances, LVP flooring, basic island (no plumbing). Keeps the existing kitchen footprint but opens it to the adjacent room. A practical choice for ranch homes and starter homes in Meridian, Nampa, and Caldwell.
Mid-Range Open Concept
$50,000–$75,000Wall removal with flush beam, semi-custom cabinets, quartz countertops, upgraded appliance package, island with seating and electrical, hardwood or premium LVP flooring, recessed lighting, and fresh paint throughout the combined space. The most popular tier for established Boise neighborhoods and move-up homes in Eagle and Southeast Boise.
Premium Open Concept
$75,000–$100,000+Multiple wall modifications, custom cabinetry, natural stone or premium quartz countertops, professional-grade appliances, large island with sink and dishwasher, custom lighting design, hardwood flooring throughout, built-in pantry, and designer finishes. May include relocating the kitchen layout entirely for optimal flow. Common in North End Boise, Eagle foothills, and Harris Ranch custom homes.
Cost ranges are based on 2024–2025 Boise-area pricing and include materials, labor, permits, and engineering. Actual costs depend on home size, wall configuration, finish selections, and scope of kitchen renovation.
Removing a wall is the structural challenge — designing the resulting space is the creative one. An open concept kitchen that functions well requires intentional planning for traffic flow, sight lines, zoning, storage, and the relationship between kitchen work areas and living spaces. Here are the key design decisions:
Island Placement and Sizing
The kitchen island becomes the defining element of an open concept kitchen. It replaces the wall as the visual and functional boundary between kitchen and living space. Standard guidelines call for 42–48 inches of clearance on all sides of the island for comfortable movement. For islands with seating, add 12–15 inches of overhang on the living room side. In most Boise homes, an island of 4–7 feet long and 3–4 feet deep fits the space. Oversizing the island is one of the most common design mistakes — it can make the kitchen feel cramped despite the open layout.
Sight Lines and Visual Flow
One of the biggest advantages of open concept is the ability to see through the space — from kitchen to living room to backyard. Design the layout so that key sight lines are unobstructed: the view from the kitchen sink to the TV, from the stove to the backyard door, and from the living room seating area back into the kitchen. Tall upper cabinets that would block sight lines are often replaced with floating shelves or eliminated in favor of a clean transition above the island.
Traffic Flow and the Work Triangle
Open concept kitchens must accommodate both kitchen workflow (sink, stove, refrigerator triangle) and through-traffic from people moving between rooms. The most successful layouts position the primary work triangle along the perimeter walls and use the island for prep space, serving, and casual seating — keeping the high-traffic path between living room and kitchen entry clear of the cooking zone.
Zoning Kitchen and Living Areas
Even in an open layout, the kitchen and living areas need visual and functional separation. Common zoning strategies include: different flooring materials (tile in the kitchen, hardwood in the living room), a ceiling detail like a soffit or beam line where the wall was, a change in paint color or accent wall, pendant lighting over the island to anchor the kitchen zone, and an area rug to define the living room seating area. The goal is cohesion with distinction — the spaces should feel connected but not undifferentiated.
Storage Solutions
Removing a wall eliminates upper cabinets and wall-mounted storage on that wall. This lost storage must be recovered elsewhere. Solutions include: a full-height pantry cabinet or walk-in pantry, deeper base cabinets along the remaining walls, island cabinets and drawers, open shelving on adjacent walls, and built-in cabinetry in the living room side for books and display. In Boise homes where the kitchen connects to a hallway or laundry room, we often add a butler's pantry or pass-through storage zone.
Every home presents unique structural and mechanical challenges during an open concept conversion. Here are the issues we encounter most frequently in Boise's housing stock:
Electrical Wiring in the Wall
Nearly every interior wall contains electrical wiring — outlets on both sides, light switches, and circuit runs to other parts of the house. When the wall is removed, every circuit must be traced, disconnected, and rerouted through the ceiling, floor, or adjacent walls. In many Boise homes built before 2000, the kitchen-to-living-room wall carries circuits for both rooms, requiring a licensed electrician to reroute and re-terminate multiple circuits. This is permitted and inspected work.
Plumbing Lines
If the kitchen sink backs up to the wall being removed, the supply and drain lines run through it. Drain lines are particularly challenging to reroute because they require proper slope for gravity drainage. In Boise homes with crawl space construction, we can often reroute plumbing through the floor system, but slab-on-grade homes (less common in Boise but present in some older neighborhoods) may require cutting the slab — a significant additional cost.
HVAC Ductwork
Forced-air heating and cooling ducts sometimes run through interior walls, particularly supply registers that feed rooms on both sides of the wall. In many Boise ranch homes, the main trunk duct runs through the crawl space and branches up through interior walls to floor or wall registers. When the wall is removed, these duct branches must be rerouted — typically by extending them through the floor or running flex duct through the ceiling cavity to new register locations.
Older Homes with Multiple Load-Bearing Walls
Pre-1970s Boise homes — particularly in the North End, Bench, and Vista neighborhoods — were often framed with multiple interior load-bearing walls rather than the long-span truss systems used in newer construction. Opening up these homes may require removing or modifying multiple walls, with each requiring its own beam and engineering analysis. The compounding complexity and cost must be evaluated carefully. Sometimes a partial wall removal or a wide cased opening (6–8 feet) achieves 80% of the open concept feel at 50% of the cost.
Floor Level Changes
Split-level and raised-ranch homes — common in Boise's 1970s–1980s neighborhoods — often have step-downs between the kitchen and adjacent living spaces. The wall removal may expose a floor level transition that needs to be addressed with floor leveling, a step, or a ramp. In some cases, the subfloor structure itself differs between the two rooms, requiring floor system modifications to create a level, continuous surface.
Matching Existing Finishes
Where the wall met the ceiling and floor, there will be gaps in the ceiling texture, flooring, and wall surfaces. Matching existing ceiling textures (especially popcorn, orange peel, or knockdown) requires skilled finishing. Flooring transitions are often the most visible — if the two rooms had different flooring (carpet in the living room, tile in the kitchen), the newly unified space needs cohesive flooring throughout. This is why we recommend addressing flooring as part of the overall project.
An open concept kitchen remodel combines structural engineering with kitchen renovation — and the sequence matters. Here is our proven 7-step process from first assessment to final walkthrough:
Structural Assessment
We evaluate the wall in question — checking joist direction, crawl space support, stacking, and identifying all electrical, plumbing, and HVAC systems within the wall. We discuss your goals for the open layout, kitchen design preferences, and budget parameters. If the wall is non-load-bearing, the project is simpler and less expensive. If it is load-bearing, we proceed to engineering.
Structural Engineering
Our structural engineer partner visits the site, performs load calculations, and designs the replacement beam system — specifying beam size, material, post locations, footings, and connection details. The engineer produces stamped plans for permit submission. This phase typically takes 2–4 weeks.
Permits
We submit the stamped structural plans and permit applications to Boise's Planning & Development Services. Separate permits are filed for structural, electrical, plumbing, and mechanical work as needed. Permit review and approval typically takes 1–3 weeks in Ada County. We handle all permit applications and coordination.
Temporary Support and Demolition
Temporary shoring walls are erected to carry the load while the permanent beam is installed. The load-bearing wall is then carefully demolished. Electrical wiring, plumbing lines, and ductwork are disconnected by the respective licensed tradespeople and tagged for relocation. Debris is removed and the opening is prepped for beam installation.
Steel Beam Installation
The engineered beam — steel I-beam, LVL, or glulam — is lifted into position and secured to the support posts per the engineer's connection details. Posts are anchored to new pier footings in the crawl space. The beam is shimmed and leveled, and the temporary shoring is carefully removed. A structural inspection is scheduled with Ada County before the beam is enclosed in drywall.
Kitchen Renovation
With the wall removed and structural work inspected, the kitchen renovation begins: electrical rough-in for the new layout, plumbing for relocated or new fixtures, cabinet installation, countertop templating and installation, appliance hookup, island construction, flooring, backsplash, and lighting. This is the longest phase — typically 6–12 weeks depending on material lead times and scope.
Finish Work and Final Walkthrough
Ceiling and wall surfaces are finished — drywall patching, texturing, and painting throughout the combined space. Trim, hardware, outlet covers, and final touch-ups are completed. All permit inspections are finalized. We conduct a detailed walkthrough with you, create a punch list of any remaining items, and ensure everything meets your expectations before the project is closed.
Boise's housing stock includes several common floor plan types that are prime candidates for open concept kitchen remodels. Here is what the conversion looks like for each:
Ranch Homes (1960s–1990s)
Before: Closed galley or U-shaped kitchen separated from the living room by a full wall. A small pass-through window or swinging door may connect the two spaces. The dining area is either a separate room or an extension of the kitchen, cut off from the living room.
After: The dividing wall is removed and replaced with a flush beam hidden in the ceiling cavity. A kitchen island with seating replaces the wall as the visual divider. The kitchen, dining, and living areas flow as one continuous space. Sight lines extend from the kitchen sink to the backyard — a transformation that makes these modest-sized homes feel significantly larger. This is the most common open concept project in Boise.
Split-Level Homes (1970s–1980s)
Before: Kitchen on the upper level with a wall separating it from the adjacent living or family room. The split-level design already creates distinct zones — the wall between the kitchen and living room adds further segmentation. These homes often feel compartmentalized and dark.
After: The wall between the kitchen and upper-level living room is removed. In split-levels, this wall is almost always load-bearing because it sits above the lower-level bearing wall. A steel beam replaces it, and the floor level transition is addressed (level, step, or integrated design feature). The result opens the entire upper level into a bright, connected living space. Natural light from living room windows now reaches into the kitchen — a dramatic improvement.
Two-Story Colonials and Traditionals (1990s–2010s)
Before: Formal dining room between the kitchen and living/family room, with walls on both sides. The kitchen may already have a breakfast nook but is closed off from the main living space. A formal living room near the entry may be rarely used while the family room behind the kitchen is the daily gathering space.
After: The wall between the kitchen and family room is removed (or the wall between the kitchen and formal dining, converting the dining room into an extension of the kitchen). In two-story homes, these walls typically support second-floor loads, requiring a substantial beam — often a steel W8 or W10 I-beam for spans of 14–20 feet. The reward is a spacious great room feel that transforms how the main floor functions. Support posts are concealed within the island or at wall terminations.
Open concept kitchen remodels involve multiple building systems, and Boise's permitting requirements reflect that complexity. Here are the permits typically needed:
Structural Permit
Required for any load-bearing wall removal. Must include stamped structural engineering plans from a licensed PE registered in Idaho. The permit covers the beam installation, post connections, and any foundation modifications (new pier footings). A structural inspection is required before the beam is enclosed. Boise's Planning & Development Services processes structural permits — typical review takes 1–3 weeks.
Electrical Permit
Required when circuits are relocated, new circuits are added, or the electrical panel is modified. An open concept kitchen remodel almost always involves electrical work — rerouting circuits from the removed wall, adding island electrical (outlets, pendant lighting), and upgrading kitchen circuits for appliances. A licensed electrician pulls the permit, and inspections are required at rough-in and final stages.
Plumbing Permit
Required if plumbing lines are relocated or new fixtures are added — such as moving the kitchen sink to an island location or adding a prep sink. Drain line relocations require particular attention to slope and venting. The plumbing permit covers both the relocation of existing lines and any new fixture installations.
Mechanical (HVAC) Permit
Required if ductwork, gas lines, or the range hood exhaust system is modified. Removing a wall that contains HVAC duct runs necessitates rerouting those ducts. Adding or relocating a gas line for a range or cooktop also requires a mechanical permit. The permit ensures all gas connections and ductwork meet current code.
Ada County Engineering Approval
All structural engineering plans must meet Ada County's adopted building codes (currently the 2021 International Residential Code with Idaho amendments). The county reviews the PE's calculations and drawings as part of the structural permit process. For complex projects involving multiple walls or unusual structural conditions, the county may request additional engineering documentation or a third-party review.
Iron Crest Remodel handles all permit applications, engineering coordination, and inspections. We work with Boise's permitting office regularly and understand the documentation requirements, typical review timelines, and inspection scheduling. You do not need to visit the permit office or coordinate with inspectors — that is our responsibility as your general contractor.
How much does it cost to remove a load-bearing wall in Boise?
Load-bearing wall removal in Boise typically costs $5,000–$20,000+ depending on the wall length, required beam size, number of new support posts, and whether electrical, plumbing, or HVAC systems run through the wall. This includes structural engineering, permits, temporary shoring, demolition, steel or LVL beam installation, and drywall finishing. A licensed structural engineer's stamped plans are required by Ada County before any load-bearing wall can be removed.
How do I know if a wall in my Boise home is load-bearing?
Common indicators include: the wall runs perpendicular to ceiling joists, it sits directly above a beam or wall in the basement/crawl space, it is located near the center of the home, or it is an exterior wall. However, visual inspection alone is never sufficient. We perform a structural assessment that includes checking joist direction, examining the crawl space or basement for support alignment, and reviewing any available original blueprints. A licensed structural engineer provides the definitive answer and designs the replacement beam system.
Do I need a permit to remove a wall for an open concept kitchen in Boise?
Yes. Any load-bearing wall removal in Boise requires a structural permit through Boise's Planning & Development Services. You will also need stamped structural engineering plans approved by Ada County. If the project involves relocating electrical circuits, plumbing lines, or HVAC ductwork — which is common — separate electrical, plumbing, and mechanical permits are also required. Non-load-bearing partition wall removal may not require a structural permit, but electrical and plumbing permits apply if those systems are affected.
How long does an open concept kitchen remodel take in Boise?
A full open concept kitchen remodel — including wall removal, structural beam installation, and complete kitchen renovation — typically takes 8–16 weeks from demolition to completion. The structural engineering and permit phase adds 3–6 weeks before construction begins. Wall removal and beam installation alone takes 1–2 weeks. The kitchen renovation portion (cabinets, countertops, plumbing, electrical, flooring, finishes) accounts for the remaining 6–12 weeks depending on material lead times and project scope.
Can any wall be removed to create an open concept kitchen?
Most walls can be removed or partially removed, but the approach and cost depend on whether the wall is load-bearing, what systems run through it, and the structural configuration above. Load-bearing walls require replacement support — typically a steel I-beam or engineered LVL beam with posts at each end. Some walls contain critical plumbing stacks, main electrical panels, or HVAC trunk lines that can be relocated but add significant cost. In rare cases with multiple load-bearing walls converging, partial removal with a remaining column or peninsula may be the most practical solution.
Will removing a wall between my kitchen and living room affect my home's resale value?
In the Boise real estate market, open concept kitchen-living layouts are consistently among the most desirable features for buyers. Removing the wall between a closed-off kitchen and adjacent living space typically increases both functional living area and perceived square footage. Zillow and Redfin data consistently show that homes with open concept layouts sell faster and for higher prices in the Treasure Valley. The key is professional execution — properly engineered beam installation, quality kitchen finishes, and cohesive design between the connected spaces.
What type of beam is used when removing a load-bearing wall?
The beam type depends on the span length, load requirements, and ceiling height constraints. Steel I-beams (W-flange) are used for long spans and heavy loads — they are the strongest option per inch of depth. Engineered LVL (laminated veneer lumber) beams are common for moderate spans and are easier to attach drywall to. Glulam beams provide a wood appearance if the beam will remain exposed. Your structural engineer specifies the exact beam size, material, and connection details based on load calculations. Beams in Boise homes typically range from 4x12 LVL for short spans to W8x steel for longer runs.
Can I keep a kitchen island where the old wall was?
Yes, and this is one of the most popular design choices in Boise open concept remodels. The island can be positioned directly where the wall stood, maintaining a natural division between kitchen and living areas while preserving the open sight lines above. If the beam requires support posts, the island can be designed to conceal a post. The island location also works well for routing electrical and plumbing to the island since the subfloor is already opened up during wall removal.
