Summary
Renton's development code makes compostables storage mandatory infrastructure, not optional: every new or infill residential, commercial, and industrial project, including single-family and middle-housing lots, must build in dedicated deposit space for compostables alongside refuse and recyclables.
A. APPLICABILITY: The provisions of this Section shall apply to all new and infill residential, commercial, and industrial development, as well as other nonresidential uses, requiring the establishment of on-site refuse, recyclables, and compostables deposit areas, as well as designated collection points for refuse, recyclables, and compostables. C.1. The refuse, recyclables, and compostables deposit areas and collection points for single-family dwellings, middle housing, and cottage house developments shall be apportioned, located, and designed as follows: a. Storage Space: Storage space for refuse, recyclables, and compostables carts must be provided either within a garage, accessory structure, or outside. Storage space for carts must measure at least two feet by six feet (2' x 6') floor area and sixty inches (60") high.

Full Breakdown
RMC 4-4-090 governs on-site refuse, recyclables, and compostables infrastructure citywide. Subsection A applies the requirement to all new and infill residential, commercial, and industrial development and other nonresidential uses, mandating the establishment of on-site refuse, recyclables, and compostables deposit areas and designated collection points as a condition of development, not merely a service customers can opt into. For single-family dwellings, middle housing, and cottage house developments specifically, RMC 4-4-090(C)(1)(a) requires storage space for compostables carts to be built either inside a garage or accessory structure, or outside on the same lot, sized to at least two feet by six feet with 60 inches of vertical clearance if placed in a garage, and identified on the building's floor plans.
The deposit area must also be screened from public view under 4-4-090(C)(1)(b) using wood, masonry, or ornamental metal, and it cannot be used to satisfy required parking space. 5 square feet per unit for recyclables deposit areas (unless the project uses individual curbside carts) and collocated compostables and refuse areas dispersed across the site if it has more than one building, fenced or screened with a six-foot wall where outdoors. Commercial, industrial, and other nonresidential uses scale the requirement by building size, up to 100 square feet minimum for larger retail projects. A screening detail plan has to be approved by the Development Services Division before building or construction permits issue.
Violations & Fines
A building or construction permit will not issue without Development Services Division approval of a screening detail plan that includes compliant compostables deposit area design, per RMC 4-4-090(B)(11). Decisions under this section can be appealed to the Community and Economic Development Administrator within 15 days in writing under RMC 4-4-090(G).
