What does it cost to add a master suite including bathroom to a home?

The cost of adding a master suite, including a bathroom, can vary significantly based on factors such as location, size, and the complexity of the design. On average, homeowners can expect to spend between $100,000 to $300,000 for this type of renovation. Additional costs may arise from permits, materials, and labor, so it's essential to budget for potential overruns. Consulting with a contractor can provide a more tailored estimate based on specific needs and local market conditions.
