Adding a second story onto your current home is a huge step. If it works, it could nearly double your home’s square footage, turning your one-story into a two-story home. You could add on a bathroom and an extra bedroom in the new space or build out your dream master bedroom.

A second-floor addition is expensive, costing $100 – $300 per square foot. A second-floor addition is the perfect way to build up, not out. This could help if your property lines are tight.

Since a second-story addition is a complex process with a high margin for error, make sure you hire an experienced contractor. Check their references on similar projects, fully vetting them before hiring them.
