Rancho Cucamonga, CA Building Safety: Green Building Code (2026)

010's adoption of the 2025 California Green Building Standards Code. 020 requires new buildings or substantial renovations, both nonresidential and residential, to comply with all mandatory provisions of the city's Green Building Compliance Matrix for that use type, maintained by the planning director, in addition to CalGreen's own mandatory provisions; compliance is checked during discretionary entitlement review or minor design review. Municipal projects face a higher bar: buildings over 7,500 square feet must implement all CalGreen Tier 1 mandatory provisions or earn 100 points on the optional matrix.

'Substantial renovation' is defined as work covering 35 percent or more of existing floor area, or any addition of new floors, with attached (but not detached) garages counted and increases aggregated over a three-year period. Buildings under 1,500 square feet are exempt unless the planning director determines otherwise, as are major and minor utilities, wireless facilities, construction storage yards, mining and processing, recycling facilities, storage yards, and temporary uses. 030 creates two voluntary incentive tiers: 'RC Green 100' projects hitting CalGreen Tier 1 or 100 matrix points get priority processing, while 'RC Green 200' projects hitting Tier 2 or 200 points get priority processing plus a reduction in one site development standard, such as setback, square footage, or required parking spaces. These provisions were adopted by Ordinance No. 1000 in 2022.
