The 120 sq ft threshold in Cincinnati trips up a lot of people — an 8x10 (80 sq ft) needs no permit, but a 12x12 (144 sq ft) does. Worth measuring before you buy. The other thing to check: Cincinnati requires sheds to be in the rear yard, and the setback from property lines varies by zoning district. A side-yard placement that works on your neighbor's lot might not be allowed on yours.

How the Process Works
Verify the Size Threshold
An 8x10 (80 sq ft) or 10x12 (120 sq ft exactly) is exempt. A 12x12 (144 sq ft) or anything larger needs a permit. Measure before you order materials.
Check Zoning and Setbacks
Cincinnati sheds must be in the rear yard with 3–5 ft setbacks from property lines. Look up your specific setback in the Cincinnati Zoning Code — it varies by district.
