Full Breakdown
Gresham Community Development Code Section 10.0200 sets sliding setbacks for detached accessory structures like sheds. Sheds under 200 sq ft need a 3-foot setback from side and rear lot lines; 200-499 sq ft sheds need 5 feet; 500-1,000 sq ft structures must meet the underlying zoning district's standard setback; anything over 1,000 sq ft is limited to lots larger than one acre. No accessory structure may sit closer to the street than the dwelling's front wall, and any shed placed within 5 feet of a side or rear property line must be moveable: built on skids or a slab with embedded pull loops, not a permanent foundation.
Violations & Fines
A shed placed too close to a lot line, ahead of the house's front wall, or set on a permanent foundation within the 5-foot moveable zone doesn't conform and must be relocated or rebuilt to meet Section 10.0203.
