Greenwood, IN Accessory Structures: Shed & Carport Rules (2026)

Section 10-03-13(C) requires an accessory structure to sit on "a property where there is an existing primary structure" and permits only "two (2) accessory structures of differing types" per lot, listing "Detached Garage," "Accessory Dwelling Unit," "Pool house" and "Shed or Barn" as the counted types; unlisted accessory structures are exempt from that two-structure cap. A lot over two acres may add one more accessory structure per acre, up to five total. Materials are size-tiered: a shed of "three hundred (300) square feet and less shall be made of wood, fiber cement, masonry or the same materials as the primary structure.

In no instance shall steel be utilized," while a shed over 300 square feet may use steel only if it adds a masonry wainscot at least 36 inches high, a five-foot planting strip of shrubs or evergreens along right-of-way-facing facades, or screens the structure from public view. Subsection (8) caps total residential accessory structure square footage, aggregated across every accessory building on the lot, at 150% of the primary structure's enclosed floor area; the location and height of the shed itself are governed by the district or zone table referenced in subsection (C)'s opening sentence rather than a single citywide number. A shed counts as construction of a structure, so the general building permit requirement in Section 7-11 applies before it goes up.
