What size house can you put on 100 x 100 lot?

The size of the house you can build on a 100 x 100 lot depends on local zoning regulations and setback requirements. Typically, you might be allowed to cover a certain percentage of the lot with your structure, often around 25-40%. This means you could build a house that is approximately 2,500 to 4,000 square feet, but specific allowances will vary by municipality. Always check with local building codes and zoning laws for precise guidelines.
