Second Story Addition Cost Calculator
Adding a second story is one of the most effective ways to double your living space without giving up your yard. However, building up is a complex project that requires careful planning, strong structural support, and a substantial budget. Our second story addition cost calculator gives you a clear picture of what to expect before you hire architects or contractors.
Understanding the Costs of Building Up
When you add a second floor, your contractor must reinforce the foundation, alter the roofline, and extend plumbing and electrical systems. Key cost factors include:
- Structural Reinforcement: Ensuring your existing walls and foundation can carry the massive weight of a new floor.
- Roof Removal and Replacement: Tearing off the old roof and framing a new one once the second story is framed.
- Interior Finishes: The quality of drywall, flooring, and bathroom fixtures you select for the new space.
Average Price Per Square Foot
Most homeowners pay between $150 and $400 per square foot for a second-story addition. Basic bedrooms and playrooms fall on the lower end, while adding full bathrooms and luxury master suites pushes the cost higher.
