Full Breakdown
Waynesville added the R-CS1 Container and Small Homes Residential District by Ordinance 2277 in 2017 specifically to give shipping-container conversions and small or tiny homes their own zoning category rather than treating them as nonconforming structures. Section 405.321 permits any shipping container or small home defined for the district as a use by right. Section 405.322 sets the area regulations: a minimum lot of 4,800 square feet for a single-family dwelling, an 8-foot side yard, a 20-foot rear yard, and a lot coverage cap of 40 percent for the combined footprint of the main structure and any accessory buildings.
Section 405.323 caps building height at two and one-half stories or 35 feet above average finished grade, the same limit used in the R-1 Single-Family District. Section 405.325 layers on design standards specific to container construction: the structure must meet the International Building Code, the exterior must be modified to remove any graffiti or shipping and transportation markings and be painted or fully enclosed in vinyl, wood, cement board or brick siding, the roof must meet the city's insulation, drainage and snow-load rules, and the applicant must submit a full set of engineering plans signed and sealed by a Missouri-licensed engineer.
Section 405.326 limits an accessory shipping-container structure, such as a garage or storage building, to one container per structure unless the Conditional Use Ordinance approves more, and requires site plan approval from the Building Official. A container or small home proposed outside the R-CS1 district needs a conditional use permit from the Planning and Zoning Commission and City Council under Section 405.324.
Violations & Fines
Chapter 405's general penalty in Section 405.740 applies: a violation is a misdemeanor punishable by a fine of ten to one hundred dollars, up to twenty days in jail, or both, with each day of noncompliance a separate offense. The Building Official can deny site plan approval for a container structure that skips the required engineering plans or exterior finish standards, and can revoke a permit already issued for defective work.
