Challenges With Using Construction Cost Per Square Foot

The construction per square foot cost is a good reference number when estimating how much you’ll need to build a new home. But it doesn’t tell the whole story due to the following reasons:

1.      Land Cost

The construction per square foot cost doesn’t include buying land, which you’ll need when building a custom house. In addition, even if you already have land, there are still additional costs for site development, clearing, permits, drives, utilities, etc. These are essential to the construction and will require you to spend thousands more than your budget if you use the construction cost per square foot.

2.      Excavation and basement costs

Excavation is necessary for construction, and if you’re planning to add a basement to your house, you might be digging a little deeper. But the construction cost per square foot only focuses on the livable space, which means it won’t include the cost of excavation and creating the basement. You’ll need to include this in the budget yourself to arrive at a closer estimate of what you need for the construction.

3.      Difference in Finishes, Materials, and Appliances

The actual amount you’ll spend on the house will depend on the materials. Materials and appliances usually take the most of the money spent on construction, and they’ll differ from one house to another. For example, it’s possible to spend as much as $400 per square foot if you choose to go for high-end materials and finishes in your house. The more quality and luxurious the appliances and materials you’re using, the more you’ll have to spend. Thus, knowing the construction cost per square foot in your zip code only gives you an idea of what an average home in your area might cost, and yours could cost a lot more or less depending on what you go with.

4.      Total Constructed Square Feet

Beyond your living space, your house lot might have a crawlspace, porch, garage, playground, decks, patios, etc. The construction cost per square foot doesn’t include all these costs, so you’ll have to add them. You’ll be surprised at what the actual cost of construction will look like after this.

Are Custom Homes Cheaper

Custom homes are rarely cheaper than already built homes of the same quality unless you’re the one building them yourself. Even then, you’ll only save between 6%  and 9% of the total cost, which is the contractor’s profit. With custom homes, the general contractor is specifically designing for you. So, they’ll also charge more for them to get a good profit margin. But such homes can be a great investment nonetheless, especially if you want something that matches your style. However, avoid building something that’s too distinct if you’re thinking of selling in the future.

In Conclusion

The construction cost per square foot differs from one location to another and constantly changes. The best way to determine yours is to use interactive online tools that calculate these costs once you enter your zip code. But you still need to consider additional costs.
