Santa Monica ADU and Energy Efficiency Rules
Santa Monica, California regulates accessory dwelling units (ADUs) and local energy-efficiency measures through city planning and building rules that work alongside state law. This guide summarizes permitting paths, technical and energy requirements, enforcement, common violations, and how to apply or appeal in Santa Monica. Refer to official city resources for full standards and current forms before filing permits.[1] For local green-building and reach-code requirements that affect new ADUs and retrofits, see the Building & Safety guidance.[2] For codified ordinances and enforcement authority, consult the Santa Monica municipal code.[3]
Overview of ADU and Energy Requirements
ADUs in Santa Monica must meet zoning, setbacks, height, parking, and building code requirements; energy-efficiency and electrification standards may apply at permit review. Planning clearance and a building permit are typically required. Where projects intersect with state ADU laws, the city implements local objective standards consistent with California requirements.
