If you’re budgeting a room addition in Providence, most projects run $26,588-$106,352, 6% above the $55,000 national average. What moves that number most is usually one thing: Addition Size. On its own it can swing the cost by $10,000 - $80,000+, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Build on a concrete slab instead of a crawl space or basement foundation to save $5,000-$15,000 on foundation costs.
In the Northeast (where Providence sits): High labor rates and strict building codes push costs up. Expect $125-$375 per sq ft in metro Boston, NYC, and DC areas.
