Adding a second story to your Rhode Island home is one of the most effective ways to increase living space without expanding your property footprint. Whether you're dealing with limited lot sizes in Providence, Warwick, or Cranston, or looking to maximize your coastal property value in Newport or Westerly, understanding the true costs of a second story addition is crucial for successful project planning.


How Much Does a Second Story Addition Cost in Rhode Island?


The average cost for a second story addition in Rhode Island ranges from $150,000 to $300,000, with most homeowners paying around $200,000 for a standard 1,000 square foot addition. Home addition cost in Providence, Rhode Island ranges from $150 to $301 per square foot.
