Vista ADU Regulations

Vista’s ADU regulations are designed to accommodate the growing interest in secondary housing units while maintaining neighborhood character and compliance with state laws. These regulations cover a broad spectrum, including zoning laws that dictate where ADUs can be built, design criteria ensuring ADUs complement the primary residence, and building standards that uphold safety and quality. Unique aspects, such as the allowance of ADUs on multifamily properties and the city’s streamlined approach to ADU development, highlight Vista’s commitment to expanding housing options.
