Get quotesPrefab vs custom
Prefab kits and ready-made sheds are cheapest and go up fast; a mid-quality built shed adds better materials and a real foundation; custom builds add windows, wiring, insulation and finishes at the top of the range.
How it’s calculated & sources
Cost = footprint (length × width) × per-sq-ft rate for the build type. Estimates are then scaled by a regional construction-cost factor for your area (U.S. average = 1.00).
Cost ranges from 2025–26 national home-improvement data (HomeAdvisor, Angi, Fixr and industry guides); regional factors approximate RS Means-style city cost indices. National average shed \u2248 $3,500 \u2014 prefab $10\u201340/sq ft, custom $30\u2013150/sq ft.
Results update as you type and are estimates, not a quote — site conditions, permits, and finishes move the final number. Verify with local pros.
