Ordinance No. 457.108

Ordinance No. 457.108 is a legislative action by the County of Riverside that amends and replaces Ordinance No. 457 to update the building requirements for unincorporated areas of the county. The primary objective is the adoption of the 2025 Building Standards Code, including the California Existing Building Code. Additionally, the ordinance implements more restrictive local standards tailored to the specific climatic, geological, and topographical conditions of Riverside County. These local restrictions specifically impact grading, fees, refunds, ponds, agricultural registration certificates, construction without a permit, work exempt from permits, and exemptions for submittal documents prepared by registered design professionals. The ordinance incorporates several specific appendices from the 2025 California Building Code, covering agricultural buildings, patio covers, grading, and emergency housing. It also adopts appendices from the 2025 California Residential Code regarding patio covers, existing buildings and structures, tiny houses, and emergency housing. This action is categorized as an administrative and organizational change intended to streamline processing requirements and is exempt from the California Environmental Quality Act as it does not constitute a project with significant environmental impact. The primary point of contact for this matter is Sam Shahrouri, the Building and Safety Official for Riverside County.
