Hard Costs to Build a House in Illinois

Hard cost comprises the cost of things directly involved in the home-building process. This includes labor costs, material costs, etc. which play a role in estimating the project completion.

Materials costs have dropped substantially post-pandemic. This is due to global supply chains returning to normal and fewer people buying homes. The following costs are included in the home building material costs:

Drywall$1.50 to $3.50 per sq. ft.

2. Labor Cost

Many professionals are involved in the home-building process. This includes electricians, architects, floor installers, plumbers, HVAC installers, carpenters, etc. Apart, you need a contractor or a firm to manage the construction process. Usually, the contractor or the firm hires the professionals involved in the construction.

The overall project cost varies depending on each professional’s hourly rates. It may further depend on the property type, detailing, materials, and workforce. Apart, the labor costs vary based on the location. For instance, in a hot real estate housing market like Chicago, home builders and labor costs are more than in other areas.

The cost of a permit in Illinois varies per county and is usually charged in accordance with construction type, occupancy type, home building area, and project scope.

Refer to your local county’s website or office for more information on building permits.

3. Home Interior Costs

To build your dream home you would purchase the desired furniture, wall prints, rugs, carpets, artifacts, etc. You may also hire an interior designer for designing the interiors of your house.

An interior designer can help you maximize space utilization. An interior designer charges $50 to $200 on average, depending on their experience and location.

House Building Financing Options

If you have the funds to finance your dream house, you are welcome to skip this section. If not, then do not lose hope. Prepare a budget and get an estimate of how much money you need, then apply for one of the following home loans:

Home Construction Loan

There are two home loans specifically designed for home-building purposes. These include:

  • Construction-to-Permanent Loan: This loan covers both land purchasing as well home building costs. Once the construction is complete and you move into the house, the loan is converted to a traditional mortgage of 15 to 30 years.
  • Construction-only Loan: It is meant only for financing the home building, and does not cover the land purchase. After your home is ready, the entire loan amount is due. You either cover the amount by paying cash or taking out a mortgage.

Personal Loan

A personal loan will not cover your entire home-building cost. Take out a personal loan to finance a specific part of the construction. Say, you forgot to account for landscaping while budgeting your home-building finances. In such a case, a personal loan can come to your rescue.

Home Equity Loan

This applies to homeowners who already have a home and want to finance the construction of a new one. Depending on how much equity you own in your existing home, you can finance the entire construction of your new home or a part of it.

Should You Build Your Own House?

If you own land in a location you want to live in, we highly recommend building a house yourself or hiring a General Contractor to build you one. Budget 9 to 12 months for planning and construction of your new home.

If you don’t own your own land in a desirable area, we recommend you house-hunt for turnkey homes and move in quickly.
