Full Breakdown
RMC 4-3-100 divides its standards into seven required elements: site design and building location, parking and vehicular access, pedestrian environment, recreation areas and common open space, building architectural design, signage, and lighting, each carrying an intent statement, prescriptive standards, and flexible guidelines under RMC 4-3-100.A.1. The regulations apply citywide to four overlay districts defined in RMC 4-3-100.B.1.b: District 'A' covers all Center Downtown (CD)-zoned land; District 'B' covers Residential Multi-Family (RMF) zones and assisted-living or convalescent facilities in several residential zones; District 'C' covers Urban Center (UC) and Commercial Office Residential (COR) zones; and District 'D' covers Center Village (CV), Commercial Arterial (CA), Commercial Neighborhood (CN), and Commercial Office (CO) zones, minus most Automall District uses.
Triggering activities listed at RMC 4-3-100.B.1.a include all subdivisions and short plats, all new structures, converting vacant land to parking or storage, converting between residential and nonresidential use, reoccupying a nonconforming structure vacant over a year, and any exterior facade, window, awning, or signage change on the affected portion of the building. Interior remodels that do not touch the facade and structures tied to existing aircraft manufacturing in District 'C' are exempt under RMC 4-3-100.C. Where these design rules conflict with any other section of the Renton Municipal Code, RMC 4-3-100.B.2 makes the design regulations control.
Violations & Fines
The Community and Economic Development Administrator reviews every covered downtown project against these standards and, under RMC 4-3-100.D.2, may approve, approve with conditions, or deny the proposal outright when no Hearing Examiner review applies. A downtown building permit that ignores the District 'A' site design, parking, or signage standards can be conditioned to add required setbacks or landscaping, or denied until the design is brought into compliance.
