Cost of adding a second story to a home in 2023

If you feel like your home is becoming overcrowded, you basically have two solutions: either move to a larger place or expand your current space.

Due to the challenges of the real estate market today, with high prices and limited options, many are inclined towards expanding their existing homes.

Think of adding a second floor to your home almost like building a new floor. For builders it’s pretty much the same process, says Gary Henley, who heads Henley Homes in Liberty Hill, Texas. They simply build the new section over the existing part of the house.

What is the price of adding a second story?

Thinking of adding another level to your home? It is not a small investment. The cost can vary widely based on many factors. This includes the size of the project, the materials you choose, and the labor rates in your area.

So, what’s the harm? On average, a second story addition costs between $300 and $500 per square foot. This means for a standard 1,000 square feet. At home, you’re looking at an expense between $150,000 and $200,000, depending on contractor platform, Fixr. For smaller homes, the cost may range from $90,000 to $120,000. Ready-made extensions are generally cheaper than custom-made ones. And bonus tip: If you can keep your existing roof intact, you’ll cut some costs, as shown by Fixr.
