How Much Does It Cost To Build a House In Illinois

Illinois is a state in the Midwestern United States. It has a population of 12,830,632 (as of 2018) and is the most populous state of the six states in the Midwest Region.

Illinois is bordered by Wisconsin to the north, Iowa to the west, and Missouri to the south; Kentucky and Indiana lie across Lake Michigan to its east. The Mississippi River forms its eastern border with Missouri; its western border with Iowa runs from northwest to southeast along 100th longitude west from Greenwich Mean Time (not counting effects of astronomical variations). This boundary separates Illinois from Missouri as well as Kentucky and Indiana as well as southern Wisconsin.

Building a home is one of the most exciting and stressful experiences in life. You get to design, build and own a new home, but don’t underestimate how much those three things cost. Looking at the average cost of building a house in Illinois can give you an idea of how much money you’ll need to put toward building your dream home. It’s also important to consider how long this process will take and what expenses might pop up along the way.


You can expect to pay between $1,000 and $10,000 per acre for land in Illinois. In Chicago, the average cost of land ranges from $5,000-$8,000 per acre. In Naperville, it’s about $2,500-3,500 per acre; Aurora averages at about $6-$7k; Joliet comes in around $1k-$7k; Rockford’s lands will run you between $1k and $7k.

Architectural Design

In architectural design, the architect is responsible for developing a plan that meets the client’s needs. The architect will work with other professionals including structural engineers and mechanical engineers to help create a building plan. They will also work with interior designers to develop floor plans and sketches of each room in the house.

Architects usually specialize in different types of structures such as residential or commercial buildings. It is important to hire an architect who specializes in homes as they can provide you with valuable information on how to build your dream home within your budget


Excavation is the first step in building a house. Excavation is the process of digging out the earth to make space for the foundation. This is usually done by a contractor, but you can do it yourself if you want to save money. You’ll need to get permission from your local planning department first though; some areas have certain legal requirements about how deep excavations should be, and some areas don’t allow you to dig at all.

If you decide that it’s worth doing on your own, here are some tips based on my experience:

  • Use a shovel instead of an excavator unless there’s something specific that it would be good for (like digging up rocks).
  • Make sure there aren’t any pipes or cables nearby before digging into the ground, you don’t want any surprises later down the line.
  • If possible, hire someone else who knows what they’re doing because this can get messy really fast–and expensive too if things go wrong.”


The foundation of your home will account for 25% to 50% of its total cost. The type of foundation you choose, as well as the soil conditions and size of your house, will have a significant impact on how expensive it is. If you’re building in an area with sandy soil or on top of a hill, for example, your foundation may need extra reinforcement or additional steps to make sure it can support the weight of your house.

The way that foundations are built also varies widely by region. In many parts of Illinois, for example (especially those near Chicago), concrete blocks are used rather than poured concrete slabs because they’re cheaper and easier to install; this type of foundation can cost from $50 per square foot up to $100 per square foot depending on how much work goes into laying them and how many materials must be purchased if they aren’t already available locally (e.g., pre-cast concrete panels). The cost could be even higher if there’s an issue with water drainage during construction draining away excess water means added costs not only in labor but also buying materials such as sheet metal sheeting (which would otherwise need replacing often).


Framing refers to the process of constructing the structural skeleton of a building. The wooden or metal framing members (beams, joists, trusses, rafters) are joined together to form the walls of a building and its roof and floor.

There are two main types of framing: balloon-framed houses and platform-framed houses. Balloon-framed houses were popular in America before 1920 because they were easy to build quickly with minimal labor cost. Platform framings were later introduced as a more efficient way to frame homes because they don’t require any interior load-bearing walls by themselves; instead, each wall is supported by another wall or beam behind it, thereby saving labor costs but increasing stability compared with balloon-framed homes which rely on shear walls for support at their ends only.


Siding is the covering of a building’s exterior surface. Siding materials include wood, fiber cement, and vinyl. Wood siding can be made from cedar, cypress, pine, or redwood; however, most new homes use manufactured wood products like vinyl and fiber cement. These are less expensive than natural wood siding but still, provide the look of traditional styles such as clapboard or shingle.

Windows, Doors, and Cabinetry

Windows and doors are a large part of the cost of building a house. The cost of windows and doors depends on the type of window or door, the material used, the size of the window or door, and the location where they are installed.

Windows and doors have different types such as fiberglass insulation, vinyl siding, and aluminum siding. Fiberglass insulation is cheaper than other insulations but it doesn’t last as long as some others like cedar wood or rigid foam insulation materials. Vinyl siding is cheap but does not offer much protection against weather elements like wind damage so you should make sure that it can withstand strong winds before buying them for installation into your new home construction project. Aluminum siding has the benefit of being resistant to rusting since aluminum weathers better than other types.

All these factors will help determine how much money each item will cost when building a new house so knowing this information firsthand will help save time during negotiations with builders/contractors who quote prices based on previous experience working together (experience sharing) which may lead to higher costs in order keep everyone happy (profit margins).


If you are building a new house, it’s important to consider the roofing materials. Roofing can be one of the most expensive aspects of constructing a home, so it’s worth taking time to select the best option for your needs.

Before you make any decisions about what type of roofing material you’d like to use, there are several things that you should keep in mind. First, think about where your new home will be located and how much rain it gets each year, this will help determine which type of shingle or metal panel would work best for your situation. Next, consider whether or not the area is prone to strong winds; if so then steel may be better than asphalt shingles because they’re stronger against high winds and hail storms. Finally, decide whether or not solar panels are an option; while they’re expensive upfront they could help save money on energy costs over time by reducing electricity bills during peak hours when rates tend to spike due to demand during heat waves, etc…

Exterior Trim

Exterior trim is the finishing touch on your house. Trim can be made of wood, vinyl or metal, and it can be painted, stained, or left natural. Our team will work with you to determine which kind of trim would look best with your exterior design preferences. We can also install trim inside of your home if you desire.

Interior Finishes

The next big step in building a home is the interior finishes. Interior finishes include flooring, cabinets, countertops, and other fixtures.

If you’re looking for something traditional or modern, there are several options available to you:

  • Flooring: Wood (hardwood/laminate), tile, and carpet are some of the most popular materials used on floors today. Vinyl also makes an appearance as it’s growing in popularity.
  • Cabinets: Plywood, particle board, and MDF are three common types of cabinet construction material used today.


You’re probably wondering what the average cost of flooring is in Illinois. If you’ve ever shopped around for flooring, you know that prices can vary greatly from store to store and type to type. The good news is that it’s relatively easy to find out what the going rate is when you have an idea of what type of flooring material you’d like installed in your home.

There are all sorts of types available, from carpeting to hardwood floors and everything in between, which means there are many options for homeowners looking for something new or different (or even both). If you don’t know where to begin, here are some suggestions:

  • Ask yourself: What kind of look do I want? A good way to narrow down your options is by considering what kind of style best matches your decorating tastes. Do they prefer something traditional? Modern? Contemporary? Maybe they need something functional as well as stylish; this could mean opting for engineered wood over solid wood planks because it makes more sense financially when used on staircases or other high-traffic areas where wear-and-tear may be more likely than usual due not just because these places get lots foot traffic but also because people tend not to notice them until there’s a problem. Make sure before purchasing anything online or offline too quickly without doing careful research first.”

Bathroom Fixtures and Fitting

The following are the bathroom fixtures and fittings you can expect to see in a new home. A toilet, sink faucet, bathtub faucet, shower head, and towel ring (or towel bar) will be included in your new home.

  • Toilet: $40 – $250
  • Sink Faucet: $20 – $300
  • Shower Head: $10 -$150

The prices shown above refer to standard models of each fixture or fitting. The price range depends on what brand of product you buy as well as its quality level. Trading up from a regular model to one with more features will increase your budget for these items significantly.

Electrical Works

When it comes to electrical work, you can expect a wide range of prices. The cost of electrical installation depends on the scale of your project and what you want to do with your wiring. It’s easy to underestimate how much labor is required for this type of work, especially if you are trying to figure out how much an electrician charges.

A basic installation might involve installing switches and outlets throughout the house along with lighting fixtures in each room. This will typically cost between $1-$2 per square foot depending on how many lights need replacing or installing and how many outlets there are in each room.

If you plan on doing some remodeling yourself then finding an electrician who will come by every once in a while (or even just once) can save you money because they charge by the hour rather than for their services overall like many other tradesmen do.

The biggest mistake homeowners make when hiring an electrician is thinking that all jobs require someone with specialized training, but unless they’re working on something very unusual like solar panels or industrial equipment then it’s usually not necessary for them to have any certifications beyond their license from the state board responsible for licensing electricians.


HVAC is the most expensive part of a house. The materials alone can cost hundreds or thousands of dollars, and that’s before you pay for labor and permits. This can be a real problem if your budget is tight, but there are many ways to cut down on HVAC costs. One way is by choosing a more affordable climate control system when designing your home. If you’re building an energy-efficient house using passive solar principles (absorbing sunlight) or wind power (capturing wind), then it makes sense to use cheap insulation since these types of systems rely on natural convection currents instead of mechanical components such as fans or heating elements. These kinds of unconventional methods might not appeal to everyone but they could save homeowners hundreds or even thousands in HVAC costs over time so it’s worth considering them before making any decisions about which type of system should go inside your new home.

Labor Costs

Labor costs are the largest component of building a house, so you’ll want to know what they are before deciding on a design and location. On average, labor costs make up between 5% and 10% of the total cost of a new home. However, this percentage will vary depending on several factors:

  • The size of your house: Labor rates tend to increase exponentially with the size of the project. So while it might cost $10/per square foot for a 600-square-foot house, it could cost $20/per square foot for an 8,000-square-foot mansion.
  • The skill level and experience level: A skilled carpenter who has worked in construction for years will charge more than someone who just decided one day that he wanted to be an electrician and even more than someone who started out as an electrician but never took any classes or did anything else related to electrical work besides installing light bulbs in lamps around their home (and maybe even replacing those lamps). Not only does experience matter here; it matters how much time that person has spent working on similar projects before. For example, if you hire someone fresh out of college who majored in architecture but has no knowledge or experience with building homes yet (or even just small ones), they probably won’t know what they’re doing, which means there’s a chance they could mess something up during construction like using incorrect materials or using incorrect methods when doing things like wiring up electrical sockets throughout your house (which could lead to fires). Make sure whoever is helping build your future home has enough skill set necessary.

Building Supplies

Building supplies are the items you’ll need to construct your home. These include lumber, drywall, paint, and plumbing fixtures. Building materials can be purchased through a general contractor or in smaller quantities from home improvement stores such as Lowe’s or Home Depot. When purchasing building supplies for a new construction project, plan on spending about $40 per square foot of finished space (the average size being 1,700 square feet). This figure is only an estimate, the actual cost of your house will depend largely on its size and location.

Landscaping Costs

Landscaping costs can vary widely depending on the quality of work you want to be done and the features you want to be added. The average range is between $5,000 and $10,000. Landscaping costs tend to be higher if you want to include ponds, waterfalls, or other special features.

You’ll also need to factor in how much time it takes for your landscaper to complete his or her work so you know when he or she will be able to start working on your house.

Permits and Licenses

Permits and licenses are required for building a house in Illinois. Permits are also required for any work that is done on the land, or anything that impacts the environment of a specific area. You will need to fill out forms and get approval from the local government before you can begin construction. If you’re planning on adding any features such as solar panels or geothermal pumps, this too requires approval from state agencies. In some cases, permits are free but others may cost several hundred dollars depending on how large your project is and what county you live in.

The Illinois Department of Natural Resources (IDNR) regulates construction projects related to water wells and septic systems while other departments manage issues related to electricity supply lines, gas pipelines, telecommunications towers etcetera.”


From flooring and roofing to the installation of electrical wiring and plumbing, labor costs can account for anywhere from 30%-50% of the total cost of building a home. Contractors charge per project, per hour, or by square footage.

Electric installation costs around $20,000, depending on the size of the home and its location. Plumbing, meanwhile, is usually several thousand dollars.


Labor and materials can be the most expensive parts of building a new house. Materials include:

  • Drywall and insulation
  • Roofing and flooring
  • Siding
  • Concrete, lumber, and other foundation materials
  • Cabinets and countertops
  • Doors and windows
  • Interior appliances (e.g., sinks, oven)

The good news is you don’t have to get everything installed all at once. You can space out your expenses and install them over time.

Materials can account for about 40-45% of the total cost to build your home. Materials include things like insulation, windows, doors, cabinets, roofing shingles, and flooring.

Building supply costs have been on the rise since the start of the pandemic due to supply chain issues, restricted availability of resources, and labor shortages.

Relatively inexpensive labor rates in Illinois combined with stable material costs – make building a very affordable option compared to other parts of the country, particularly the Northeast or California.

Average Cost To Build a House In Illinois

The average cost to build a house in Illinois is $187,000. The average cost to build a home in the U.S., on the other hand, is $280,000, a difference of around 20 percent. If you’re looking for something with more square footage than that but still affordable, consider moving somewhere else.

The average cost to build a home in Illinois is $187,000

In conclusion, the average cost to build a house in Illinois is $220,034. This figure takes into account all costs associated with building a home including land acquisition, architectural design, construction labor, materials, and equipment needed for the various stages of construction.
