How This Estimate Is Calculated
Each project starts from the national-average cost range in its guide, then adjusts it for four factors:
- Location — labor and material prices run lower in rural areas and substantially higher in major metros like New York or San Francisco.
- Project scale — a compact build costs less than a standard one; a large or premium-sized build costs more.
- Finish quality — budget, mid-range, or high-end materials and finishes.
- DIY vs. professional labor — doing work yourself lowers cost but lengthens the timeline.
The result is broken down into materials, permits and fees, and labor. Treat it as a planning estimate and get quotes from licensed contractors before starting.
