ADU Zoning and Approval Process in Calabasas

In Calabasas, most single-family homes and select multifamily properties can accommodate Accessory Dwelling Units, though approval depends on the specific lot. Planning a Calabasas ADU means considering setbacks, building height, lot coverage, utility connections, parking requirements, and any HOA or CC&R guidelines. Homes near hillsides or within Wildland–Urban Interface (WUI) zones may require extra review for fire safety, drainage, and emergency access.

Our feasibility review looks at zoning, parcel layout, utilities, and site access to map the smoothest route to approval for your Calabasas Multifamily ADU. While each property is unique, this early assessment ensures your project aligns with local regulations and maximizes efficiency from planning through permitting.

  • Construction & On-Site Build – Manage foundation work, utility connections, and the installation of prefab or custom ADUs, ensuring inspections are completed for compliance.
